Grilling asparagus is a delicious and healthy way to enjoy this versatile vegetable. However, getting the cooking time right can be tricky, and overcooked or undercooked asparagus can ruin your meal. In this article, we’ll discuss how long to grill asparagus to achieve tender, flavorful, and perfectly cooked spears every time.
Selecting and Preparing Your Asparagus

Before you start grilling, you need to choose the right asparagus and prepare it properly. Look for firm, bright green asparagus spears that are uniform in size, with tightly closed tips. The thicker the spears, the longer they will take to cook, so adjust your cooking time accordingly.
To prepare your asparagus for grilling, wash the spears under cold running water and trim off the tough, woody ends. You can do this by bending the spears near the bottom until they snap. The snapped ends will be the tough part you want to remove.
Preheating the Grill

Before grilling your asparagus, make sure your grill is clean and preheated. Preheat your grill to medium-high heat, around 400┬░F, and lightly oil the grates to prevent the asparagus from sticking.

Now it’s time to grill your asparagus. Place the spears on the grill in a single layer, making sure they are not too crowded. You can also use a grilling basket to keep the asparagus from falling through the grates.
Grilling Time
The cooking time for asparagus will depend on the thickness of the spears and the heat of your grill. Here’s a general guideline for how long to grill asparagus:
- Thin asparagus spears (1/4 to 1/2 inch thick) should be grilled for 2-3 minutes per side.
- Medium asparagus spears (1/2 to 3/4 inch thick) should be grilled for 3-4 minutes per side.
- Thick asparagus spears (3/4 to 1 inch thick) should be grilled for 4-5 minutes per side.
Checking for Doneness
To check if your asparagus is done, use tongs to gently lift one spear from the grill and pierce it with a fork or knife. It should be tender but still slightly firm. If it’s too crunchy, grill for another minute or so.
Grilling Options
If you want to add some extra flavor to your asparagus, try grilling it with some olive oil, salt, and pepper, or drizzle some lemon juice over it before serving. You can also grill asparagus wrapped in bacon for a decadent treat.
