How To Make Grilled Asparagus

Getting Started:

Get the grill ready by turning the heat on medium-high, it needs to be nice and hot before adding the asparagus.
Prepare spears by washing them well and trimming off the woody ends, pat dry.

Basic Recipe Ingredients:

2 tablespoons of extra-virgin olive oil
1 pound (1 bunch) asparagus
Kosher salt
Freshly ground pepper

Directions:

Toss or brush the asparagus with oil so they’re evenly coated, sprinkle with salt and pepper (you can do this in a bowl or in a ziploc bag).
Lay each spear directly on the grill (sideways from the grill direction so they won’t fall through) and cook with the lid open. Turn the asparagus frequently to cook evenly.
Grill until just tender and the tips begin to brown (total cooking time is approximately 5 minutes up to 10 minutes depending on thickness of spears).

That’s how easy it is! More tips below…

Tips

Tasty Twist: Try drizzling your favorite vinaigrette dressing over the asparagus once it’s cooked, nice kick of flavor! Or you can add it to the oil when coating the stalks (use about 1/2 tablespoon of vinaigrette to 1 tablespoon olive oil).
Lemon & Garlic Twist: Add 1 Tablespoon of fresh lemon juice with 1 tablespoon of olive oil, use this to coat the asparagus before adding to the grill. If you’d like a bit of garlic in the mix, add 1 crushed clove. Let the spears sit in this mix for a few minutes before grilling.
Less Fussy To Handle: If grilling asparagus is too fussy for you (having to turn and handle each spear one at a time), here’s a tip for you: Soak bamboo skewers in water for about 20 minutes (so they won’t catch on fire), then stick 4 to 5 stalks of asparagus onto skewers (one skewer on each end–spear sideways). You’ll be grilling and flipping bunches of asparagus quickly with this method!
Non-stick Spray: A quick and easy way to make asparagus non-stick is to spray them with non-stick cooking spray first (instead of coating them with olive oil). If you do spray them, do this on a plate and not directly on the barbecue since the spraying could ignite a fire.
No Barbecue or Grill? Try these in the oven! Arrange oil coated and seasoned asparagus spears on a baking sheet and stick under the broiler in the oven (preheated). Turn once and remove from oven when tender (approximately 5 to 10 minutes).
