Grill Asparagus Perfectly Every Time: Top Tips

You know that feeling when you're staring at a bundle of asparagus at the market, thinking, "I could grill this," but you're pretty sure you'll end up with either a pile of charcoal or a sad, floppy mess? That's exactly why we're here. The truth about how to grill asparagus perfectly is that it's not about luck or fancy equipment.

It's about reading a few visual cues, controlling your heat, and nailing the timing.

In our research, the difference between mediocre and perfect grilled asparagus comes down to one thing: the visual doneness test. A properly grilled spear holds its bright green color, develops caramelized char marks, and bends slightly at the tip when lifted. That's the "nod" we'll walk through step by step.

As of 2026, most home grill masters still overcook their vegetables by relying on timers instead of visual cues, so let's fix that today.

Quick Answer

Heat your grill to medium-high, about 400-450°F. Snap off the woody ends. Toss spears in olive oil and kosher salt.

Grill 3-8 minutes depending on thickness. Turn halfway through. Remove when tips "nod" and spears are bright green with char marks.

Serve immediately.

What You Need Before the Grill Is Even Hot

Getting perfectly grilled asparagus starts long before the flame touches the vegetable. You need the right spears, the right tools, and the right oil. Let's break down each piece so you're not scrambling mid-cook.

The Spears: Thickness Matters More Than You Think

Asparagus thickness isn't just about aesthetics. It determines your entire cooking strategy. Pencil-thin spears (under 1/2 inch) cook in about 3-4 minutes and need constant attention.

Standard spears (1/2 to 3/4 inch) are the sweet spot, taking 5-6 minutes with a nice balance of crisp exterior and tender interior. Jumbo spears (over 3/4 inch) take 7-8 minutes and handle higher heat without burning.

When you're at the store or farmer's market, don't grab the first bundle. Look for spears with tightly closed tips and firm stalks. If the cut ends look dried out or cracked, move on.

Fresher spears snap cleanly and hold up better on the grill.

Tools That Save You From Disaster (Grill Basket vs. Bare Grates)

Your grilling surface matters more than most people realize. Here's the quick breakdown:

A grill basket is your best friend if you're cooking thin spears. The holes let heat and smoke hit the asparagus while keeping everything contained. If you're going bare-grate, place spears perpendicular to the grates so they don't fall through.

Oil, Salt, and the One Seasoning You Should Skip

Keep it simple. Olive oil is ideal because it has a smoke point around 375-405°F, which handles your 400-450°F grill without burning. Kosher salt enhances natural sweetness without overpowering it.

That's genuinely all you need for perfect grilled asparagus.

Here's what to skip: garlic powder. It burns quickly at grilling temps and leaves a bitter, acrid taste. Same goes for dried herbs.

Save those for after grilling if you want them. If you're feeling adventurous, a light squeeze of lemon after cooking adds brightness without compromising the grill flavor.

Step 1: The Snap – Finding the Exact Point Where the Woody End Begins

The most common mistake with asparagus is not trimming enough off the bottom. The woody, fibrous end ruins the texture of every bite. But cutting too much wastes perfectly good asparagus.

Here's the trick: hold the spear with both hands, one near the base and one in the middle. Gently bend until it snaps naturally. The asparagus breaks exactly where the tender flesh ends and the woody stem begins.

It's not random. It's a biological weak point that's been there all along.

If you're cooking a large batch, snap one spear first, then line up the rest against it and cut them to match. This keeps everything uniform for even grilling. Don't snap each one individually, you'll drive yourself crazy and end up with inconsistent lengths.

What about peeling? Unless you've got exceptionally thick jumbo spears, skip it. Peeling removes the outer layer that helps spears hold their shape on the grill.

For pencil-thin spears, peeling is pointless you'll lose half the vegetable.

Step 2: Coating and Seasoning – How to Get Even Coverage Without Pooling Oil

Pouring oil directly onto the pile and hoping for the best doesn't work. You'll end up with some spears drowning while others stay dry and burn. The technique is simple but specific.

Put your prepared spears on a rimmed baking sheet. Drizzle about one tablespoon of olive oil per pound of asparagus over the top. Then use your hands to toss and rub the spears, making sure every surface gets a thin, even coating.

The oil should barely coat the spears, giving them a slight sheen without any pooling at the bottom of the pan.

Season with kosher salt right after oiling. Don't salt before the oil, the salt won't stick evenly. And wait to season until just before grilling.

Salt draws moisture out of vegetables over time, and we want the exterior dry enough to caramelize rather than steam.

Here's a pro tip: if your spears are uneven in thickness, cut them so they're similar in size before coating. This ensures everything cooks at the same rate, which is the real secret to perfectly grilled asparagus.

Step 3: Reading the Heat – Why 400-450°F Is the Sweet Spot (and How to Know You're There)

Temperature control is where most home cooks get into trouble. Too low and the asparagus steams instead of charring. Too high and you've got burnt exteriors with raw, crunchy centers.

The ideal grill surface temperature is 400-450°F. This range delivers those beautiful caramelized char marks while protecting the interior moisture. It's hot enough to trigger the Maillard reaction but gentle enough to cook the spear through.

How do you know you're in the zone without a fancy thermometer? Hold your hand about five inches above the grate. You should be able to keep it there for about five seconds before needing to pull away.

That means you're in the medium-high range. If you can't make it past two seconds, it's too hot.

Preheating is non-negotiable. Give your grill at least 10-15 minutes with the lid closed before placing any asparagus on it. Charcoal grills need a little longer, until the coals are covered in gray ash with a warm orange glow peeking through.

For gas grills, set all burners to medium-high and let the grates heat fully before adding your oiled spears. This ensures your grill marks will actually form, and the spears won't stick to the surface.

Step 4: The Grill Layout – Perpendicular Placement and Why Crowding Ruins Everything

Placement on the grill affects doneness more than you might expect. Think of it like this: hot air and flames need to circulate around each spear. If they're stacked on top of each other, the ones underneath steam rather than grill.

Place each spear perpendicular to the grill grates. This gives you maximum contact with the hot surface and prevents the spears from sliding between the bars. A grill basket changes the rules slightly, but you still want airflow between the spears.

Leave space between each spear. A finger's width of gap is the minimum. If you're cooking a big batch for a crowd, work in smaller batches instead of cramming everything on at once.

Crowding leads to two problems: uneven cooking and a drop in grill temperature.

Here's the science bit. When you load up a grill, the temperature drops significantly. It takes time to recover, and that recovery period is when your asparagus ends up steaming.

By keeping batches manageable, you maintain steady heat and get those beautiful char marks without fail.

The first side cooks for most of the total time. For standard spears, that's about 3-4 minutes with the lid open. You'll see the spears start to soften slightly and develop some blistered skin.

That's your cue to flip.

Once flipped, the second side cooks faster. About 2-3 minutes for standard spears. You're not looking for equal char on both sides.

You want one side with deep caramelized marks and the other with lighter grill lines. That contrast is part of what makes grilled asparagus so visually appealing.

Don't fiddle with the spears constantly. Let them sit. If you're using tongs, pick them up gently.

Piercing the flesh with a fork releases moisture and dries out the interior. Tongs are the right tool because they grip without damaging the spear's structure.

The lid position matters too. Leave it open for direct heat cooking. Closing the lid turns your grill into an oven, which accelerates cooking and can lead to overcooked, limp spears before you even notice.

Unless you're dealing with jumbo spears that need extra heat penetration, keep the lid up and watch the sizzle.

Step 5: The Flip – Visual Cues for the Exact Right Moment

You don't need a timer. You need your eyes. The flip happens when the first side shows clear signs of caramelization, about 60-70% of the total cook time.

For pencil-thin spears, that's around 2 minutes. For standard spears, 3-4 minutes. Jumbo spears, 5-6 minutes.

But here's the thing: those numbers are starting points, not gospel. Your specific grill, the outdoor temperature, and the thickness of your spears all shift the timeline.

Look for these visual cues before flipping:

• The spears have developed a bright green color with glossy, blistered skin
• You can see dark brown or black char marks where the spear touches the grate
• The spears have started to soften but still hold their shape when lifted
• Watery liquid is no longer pooling on the surface (that means surface moisture has evaporated)

If the spears look shriveled or gray-green, you've waited too long. If they're still pale and wet with no char, give them another minute. Trust what you see, not what the clock says.

Using tongs, flip each spear gently. If a spear resists the flip or sticks to the grate, leave it for another 30 seconds. It's not ready yet.

Forcing it will tear the skin and leave behind valuable flavor.

The second side doesn't need as much color. Just enough char to mark it. Once you flip, you're most of the way to done.

Start checking for doneness after about 90 seconds on the second side.

One more thing about the flip: don't rotate spears 180 degrees unless you're going for cross-hatch marks. That's a restaurant-style presentation trick that requires two flips and adds minimal flavor. For home cooking, a single flip is all you need.

If you're noticing hot spots on your grill, adjust spear placement during the flip. Move spears from the hotter zones to cooler ones, or vice versa, to encourage even cooking across the entire batch. This is especially important on charcoal grills where heat distribution is rarely uniform.

Step 6: The Doneness Test – The "Nod" and Other Visual Checks That Beat Any Timer

Here's where everything comes together. The perfect doneness isn't about minutes, it's about how the spear behaves. The "nod" test is the most reliable method we've found in our research.

Pick up a spear with your tongs, holding it horizontally. Let the tip hang free. If the spear is perfectly cooked, the top inch or two will gently droop downward, ceiling toward the ground.

That's the "nod." It means the interior is tender without being mushy. The spear still holds its shape overall, but the tip shows flex.

If the spear stands completely rigid with no bend at the tip, it needs more time. If it folds over completely like a wet noodle, it's overcooked. The range between those extremes is narrow, maybe 60 seconds of cooking time, which is why visual checks beat timers every time.

Here are the other visual checks that confirm doneness:

• Color: Bright, vivid green with no gray or olive tones. Gray indicates overcooking
• Texture: Blistered skin with visible char marks. The surface should look slightly wrinkled, not smooth and glossy
• Aroma: Smoky caramelization with a hint of sweetness. If you smell sulfur or cabbage, you've gone too far
• Sizzle: The spears should still sizzle slightly when you lift them. If they're quiet, they've lost too much moisture

The USDA recommends cooking vegetables to an internal temperature that ensures food safety, but for asparagus, the texture and color cues matter more than any number. As noted in USDA guidelines for safe produce handling, washing your spears before grilling and keeping them at proper temperatures prevents any foodborne illness risks. The heat from your grill easily handles any surface pathogens.

Pencil-Thin Spears (3-4 Minutes)

These cook fast. Start checking for the nod at the 3-minute mark. They can go from perfect to overcooked in under 45 seconds, so stay vigilant.

The window for removing them is small.

Standard Spears (5-6 Minutes)

The forgiving middle ground. Check at 5 minutes, then again at 5.5 minutes if needed. These give you a little breathing room, but don't wander off.

Jumbo Spears (7-8 Minutes)

These need the full time and benefit from slightly lower heat. If your grill runs hot, move them to a cooler zone after the first flip. Check for the nod at the 7-minute mark and go from there.

Once you pull the spears off the grill, they continue cooking from residual heat. That's why removing them at the first sign of the nod is so important. If you wait until they look fully done on the grill, they'll be overdone by the time you serve them.

Transfer the spears to a serving platter immediately. Don't stack them in a pile where they'll trap steam and continue cooking. Spread them out in a single layer.

If you're serving a crowd, you can keep them warm by loosely tenting foil over the platter for a few minutes, but don't leave them covered long. Condensation forms and ruins that crisp-tender texture.

The Visual Guide to Char: Good Blistering vs. Burnt Disaster

Not all char is created equal. Understanding the difference between beautiful caramelization and bitter burning is what separates decent grilled asparagus from genuinely perfect grilled asparagus.

Good char looks like this: dark brown patches with occasional black tips on the edges. The surface has a slightly wrinkled, blistered appearance. When you bite into it, you get a smoky, slightly sweet flavor with no bitterness on the finish.

Burnt asparagus looks like this: large areas of solid black, ash-gray coloring, or shriveled, paper-thin skin. The flavor turns acrid and unpleasant, masking the natural sweetness of the vegetable entirely.

Here's a quick reference table for what to look for:

The sweet spot is medium char. You want visible grill marks spanning about 30-40% of the spear's surface. This comes from letting the spears sit long enough on each side without moving them around excessively.

What causes burnt spears? Usually one of three things: the grill is too hot, you're using too much oil that drips and flares up, or you've walked away and let time slip. All three are fixable with the techniques we've covered already.

Common Mistakes That Turn Perfect Asparagus Into a Floppy Mess

Even experienced cooks make these errors. Let's go through the five most common ones so you can avoid the disappointment of ruined asparagus.

Mistake #1: Skipping the Snap (Woody Texture)

You're in a hurry, so you just chop off the bottom inch and call it done. That's not enough. The woody portion extends further up than most people think.

Skipping the snap means every bite has a fibrous, stringy texture that's unpleasant no matter how well you grill the rest.

Mistake #2: Too Much Oil (Flare-Ups and Soggy Results)

More oil doesn't mean more flavor. It means dripping oil hitting the flames, causing flare-ups that coat your asparagus in soot. It also creates a steamed texture instead of a grilled one.

Use that one tablespoon per pound and no more.

Mistake #3: Overcrowding (Steaming Instead of Grilling)

When spears overlap, they trap steam between each other. The result is gray-green, limp asparagus with no char marks at all. You're not grilling at that point.

You're steaming with a hint of smoke.

Mistake #4: Grilling Cold Spears (Uneven Cooking)

Straight from the fridge to the grill means the exterior cooks before the interior warms up. Let your trimmed, oiled spears sit at room temperature for 15-20 minutes before grilling. This ensures even cooking throughout.

Mistake #5: Walking Away (Asparagus Goes From Perfect to Ruined in 60 Seconds)

Asparagus has a narrow window between done and destroyed. Thin spears especially can cross that line in under a minute. Stay at the grill.

This isn't the time to run inside for another drink.

Grilled Asparagus vs. The Alternatives: Is the Grill Actually Worth It?

People ask us all the time whether the grill is truly worth the effort compared to other cooking methods. The short answer is yes, but only if you want that specific smoky, caramelized flavor. Here's how grilling stacks up:

Roasting is the closest competitor. You get even browning and a sweet flavor, but you miss that smoke component entirely. For a weeknight when you don't want to fire up the grill, roasting at 425°F for 12-15 minutes works beautifully.

Steaming is the texture killer. It produces limp, waterlogged spears with no flavor development. If you're only steaming because you think it's healthier, skip it.

Grilling doesn't add unhealthy fats beyond the light oil coating, and it makes vegetables far more appealing.

Sautéing in a hot skillet gets you close to grilling. The high heat creates similar caramelization. But you lose the smoky element, and it's easier to overcrowd a pan than a grill grate.

The grill wins for flavor and texture, period. The only reason to skip it is time or weather, and that's what the indoor alternatives are for.

How to Grill Asparagus Without a Grill: Indoor Options That Come Close

Sometimes the weather doesn't cooperate. Sometimes you just don't want to deal with charcoal. We get it.

You can still get respectable grilled asparagus without ever stepping outside.

Cast-Iron Grill Pan (The Closest Substitute)

A cast-iron grill pan is the best indoor mimic for outdoor grilling. The raised ridges create those signature char marks, and the heavy iron holds heat like a pro grill grate. Preheat the pan over medium-high heat for a full five minutes.

It needs to be smoking hot before the oiled spears hit the surface.

The downside is ventilation. Smoke accumulates quickly indoors, so turn on your range hood and crack a window. If you don't have a grill pan, a regular cast-iron skillet works too, just without the aesthetic grill marks.

Broiler Method (Vertical Heat, Same Char Effect)

The broiler is the overlooked hero of indoor vegetable cooking. It delivers intense, direct heat from above that caramelizes the natural sugars in asparagus beautifully. Position your oven rack about six inches from the broiler element.

Place oiled, seasoned spears on a rimmed baking sheet in a single layer.

Broil for 4-6 minutes, flipping once halfway through. The top surface will blister and char while the interior stays crisp-tender. Check frequently because broilers cook fast and unevenly.

Different spots in your oven will char faster than others, so rotate the pan if needed.

What to Serve With Grilled Asparagus (and How to Repurpose Leftovers)

Perfectly grilled asparagus is a side dish that can anchor an entire meal. It pairs naturally with proteins and grains without needing much else to shine.

Pairings That Make It a Full Meal

Grilled steak is the classic companion. The smoky char on both the beef and the asparagus creates a cohesive flavor profile that feels intentional rather than thrown together. Grilled chicken works similarly, especially with a lemon-herb marinade.

For seafood, grilled salmon or shrimp match well. The asparagus's slight bitterness cuts through the richness of the fish. Over a bed of risotto or quinoa, grilled asparagus adds texture and visual appeal that makes a vegetarian main course feel complete.

Add a soft-boiled egg and shaved Parmesan on top of the grilled spears, and you've got a bistro-style salad that's substantial enough for lunch. The warm asparagus slightly wilts the greens underneath, creating a nice layered effect.

Cold Asparagus for Salads and Grain Bowls

Leftover grilled asparagus is a gift the next day. Chop cold spears into 2-inch pieces and toss them into a farro or quinoa salad. The smoky flavor infuses the entire dish.

They also work beautifully chopped into omelets or frittatas for breakfast.

To keep leftovers at their best, store them in an airtight container in the fridge for up to three days. Don't reheat them in the microwave. Eat them cold, or warm them gently in a hot skillet for 30 seconds per side.

Frequently Asked Questions

Should I Peel Asparagus Before Grilling?

No, except for the thickest jumbo spears. Peeling removes the outer layer that holds the spear together on the grill. For standard and pencil-thin spears, the skin blisters and caramelizes beautifully as-is.

For jumbo spears over 3/4 inch thick, a vegetable peeler run from just below the tip to the base helps even out the cooking.

Do I Need to Soak Asparagus in Water First?

No. Soaking adds moisture that you'll have to evaporate before caramelization can happen. It promotes steaming instead of grilling.

Your spears should be dry to the touch after oiling, with just a thin sheen of olive oil. If anything, less moisture is better.

Can I Use Frozen Asparagus on the Grill?

Technically yes, but the texture suffers. Frozen asparagus releases significant water as it thaws, which means steaming instead of grilling. If you're in a pinch, thaw completely and pat every spear dry before oiling.

Expect mushy tips and less distinct grill marks. Fresh asparagus is always worth the difference.

How Do I Keep Asparagus Warm Without Overcooking It?

Spread cooked spears in a single layer on a serving platter. Loosely tent with foil for up to 10 minutes. Don't pile them up, and don't leave them covered longer than that.

If you need to keep them warm longer, your best bet is to slightly undercook them by about a minute and let residual heat finish the job.

Can I Prep Asparagus the Night Before?

You can snap and trim the spears a day ahead. Store them in the fridge in a sealed container with a damp paper towel. Don't oil or season them until just before grilling.

Doing it earlier draws out moisture and can make the spears wilt before they ever hit the heat.

The Final Verdict: A 60-Second Checklist for Perfect Grilled Asparagus Every Time

Here's everything we've covered, distilled into a quick reference you can use at the grill. Save this checklist, print it, or memorize it. It takes about a minute to run through.

• Snap the woody ends, don't guess where they start
• Coat with 1 tablespoon olive oil per pound, then add kosher salt
• Preheat the grill to 400-450°F with the lid closed for 10-15 minutes
• Place spears perpendicular to grates with finger-width gaps between them
• Grill 2-4 minutes per side depending on thickness, lid open
• Flip when blistered and bright green with visible char marks
• Remove when the tip "nods" gently downward
• Spread in a single layer and serve immediately

That's the whole process. No complex equipment, no tricky techniques, just attention to what your asparagus is telling you. Once you've done it a couple of times, you'll read the cues automatically.

You'll know exactly when to flip and precisely when to pull the spears off the grill.

The confidence that comes from understanding the visual cues is the real payoff here. You're no longer guessing with a timer. You're cooking with your eyes, adjusting on the fly, and producing consistently perfect results.

That's what knowing how to grill asparagus perfectly is really about. It's not a recipe. It's a skill, and now you've got it.

Real Scenarios: What Grilling Looks Like in Practice

Let's put all these cues together in a few real situations you'll actually encounter. Each one shows how the visual checks adapt to the conditions in front of you.

The Farmer's Market Bundle. You bought thick, jumbo spears from a local grower. They're uneven, some nearly an inch thick. Don't worry.

Snap each one individually, toss in oil and salt, grill over medium heat (around 400°F) for 6 minutes per side. The nod test still applies, just later. Check at the 7-minute mark and adjust from there.

The Last-Minute Weeknight. You've got pencil-thin spears and a screaming-hot gas grill. Your window is tight. Grill them for 90 seconds per side, pull them when the tips just start to bend, and serve immediately.

They'll finish cooking on the plate, so don't wait for the full nod.

The Cookout for Eight. Asparagus for a crowd means batch cooking. Grill one batch, transfer to a platter in a single layer, and tent loosely with foil. Start the next batch while the first rests.

Each batch takes 6-8 minutes, so plan for about 20 minutes of grill time total.

Expert Tips for Taking Grilled Asparagus to the Next Level

Once you've mastered the basics, these refinements elevate your results.

Add a finishing acid. A squeeze of fresh lemon juice over the hot spears brightens the smoky flavor and cuts through the oil. It's the single easiest upgrade you can make.

Sprinkle with flaky salt right before serving. The coarse crystals provide bursts of salty crunch that contrast beautifully with the tender flesh. Standard kosher salt works fine for grilling, but flaky sea salt really shines at the end.

For heat lovers, a pinch of red pepper flakes after grilling adds warmth without overwhelming the asparagus's natural flavor. You can also add them to the oil before coating for deeper penetration.

Store your leftover grilled asparagus in a sealed container in the fridge. They'll keep for up to three days. Chop them cold into salads, pasta, or omelets for an easy flavor boost later in the week.

Frequently Asked Questions

How Do I Know When Grilled Asparagus Is Done?

The nod test is your best guide. Pick up a spear with tongs and hold it horizontally. If the tip droops gently downward, it's done.

Color matters too. Bright green with visible char marks means ready to eat.

Why Is My Asparagus Soggy?

Too much oil or overcrowding causes soggy spears. Excess oil creates steam, and overlapping spear traps moisture between them. Use one tablespoon of oil per pound and leave finger-width gaps between spears on the grate.

Can I Marinate Asparagus Before Grilling?

Yes, but keep it simple. A light marinade with lemon juice, olive oil, and herbs works well for 15-30 minutes. Skip sugar-based marinades, they burn quickly at grilling temperatures.

Pat spears dry before oiling to avoid steaming.

Should the Grill Lid Be Open or Closed?

Keep it open for standard and pencil-thin spears. The lid traps heat and turns your grill into an oven, which overcooks the exterior before the interior catches up. For jumbo spears, closing the lid briefly on the second side helps cook them through.

Tighten up the beginning of your article introduction to be more direct and benefit-driven, taking into account the true search intent. Use a shorter, punchier structure; eliminate the throat-clearing and focus on the immediate "reader pain point" while keeping the keyword in sentence 1 or 2. Aim for 2-3 punchy sentences that throw the reader into the action.

Then add a second paragraph that in a sentence or two introduces the visual doneness method and why it's superior to timers, using a metric or timing anchor, ending with a transition to the Quick Answer section.

Safety, Storage, and Grill Maintenance

Proper handling keeps your grilled asparagus safe to eat and your equipment in top shape. The USDA recommends washing fresh produce under running water before trimming. Since you're cooking at 400-450°F, any surface bacteria are easily eliminated, but washing also removes dirt and residue.

After grilling, don't leave spears sitting out longer than two hours. That's the USDA's safe window for perishable foods at room temperature. If you're serving outdoors in warm weather, shrink that window to one hour.

For storage, cooled asparagus goes into an airtight container in the fridge. It stays good for up to three days. Reheat gently in a hot skillet for 30 seconds per side, or eat cold in salads.

Avoid the microwave, it turns the texture mushy.

Cleaning your grill grates after cooking prevents rust and stuck-on food buildup. Brush hot grates with a wire grill brush right after you pull the food off. Then wipe with a paper towel dipped in a little oil to create a protective layer for next time.

Troubleshooting Quick Fixes

If your asparagus is consistently burning on the outside but raw in the center, your grill is running hotter than you think. Dial it back to around 375°F and extend the cook time slightly. The visual cues stay the same, they just take longer to appear.

When to Skip Grilling Altogether

Honestly, some asparagus just isn't worth grilling. If your spears are limp, slimy, or have a strong sulfur smell at the market, they're past their prime. Grilling won't improve them.

Choose a different vegetable or a different cooking method.

Also, skip grilling if you're cooking for someone who can't eat charred foods due to digestive sensitivities. Roasting or steaming provides a milder flavor that's easier on the stomach. Asparagus is still delicious those ways, just different.

Final Checklist for Next Time

• Snap woody ends, don't cut blind
• Coat with one tablespoon olive oil per pound
• Season with kosher salt just before grilling
• Preheat grill to 400-450°F for 10-15 minutes
• Place spears perpendicular to the grates
• Keep finger-width gaps between spears
• Grill 3-8 minutes total based on thickness
• Flip once when blistered and bright green
• Remove when the tip "nods"
• Serve immediately in a single layer

That's the entire process. Run through this checklist once or twice, and the visual cues become second nature. You'll know exactly when to flip and pull without even thinking about it.
