1. Selecting and Preparing the Asparagus

Choose fresh, firm asparagus with tightly closed tips. Thicker spears are better for grilling because they won’t fall through the grates and are less likely to overcook.

Preparation steps:

1. Wash and trim – Rinse the asparagus and snap off the tough woody ends (usually the bottom 1–2 inches).

2. Dry thoroughly – Moisture prevents proper browning.

3. Season lightly – Toss the asparagus with olive oil, salt, and black pepper. You can add minced garlic or lemon zest for extra flavor.

2. Preheating the Gas Grill

Preheat your gas grill to medium-high heat (400–425°F / 200–220°C) for about 10 minutes with the lid closed. Make sure the grates are clean and lightly oiled to keep the asparagus from sticking.

You can grill directly on the grates, or use a grill basket or foil sheet if your asparagus spears are thin.

3. Grilling the Asparagus

Place the asparagus in a single layer across the grill grates, perpendicular to prevent them from slipping through.

• Cook time: 5–8 minutes total

• Turn every 2–3 minutes for even charring

• Close the lid occasionally to trap heat and enhance smokiness

Once the asparagus turns bright green with light char marks, remove it from the grill immediately to prevent overcooking.

4. Finishing Touches

After removing from the grill, drizzle the asparagus with a finishing touch to enhance flavor:

• Lemon juice or balsamic glaze for brightness

• Grated Parmesan cheese for a savory note

• Crushed red pepper for mild heat

• Olive oil and garlic butter for richness

Toss gently and serve warm.

5. Additional Grilling Tips

• Don’t overcrowd the grill—give each spear room for heat circulation.

• Keep an eye on thin asparagus; they cook very quickly.

• For smoky flavor, grill with the lid closed part of the time.

• Use tongs to turn the asparagus instead of a fork to avoid piercing the spears.

• For easy cleanup, line the grill with foil brushed in oil before cooking.

6. Serving Ideas

Grilled asparagus is a versatile side dish that pairs perfectly with:

• BBQ steak or chicken

• Grilled salmon or shrimp

• Roasted potatoes and vegetables

• Fresh pasta or salad

You can also chill grilled asparagus for use in cold salads, wraps, or as a topping for pizza and sandwiches.
