Snap the ends off of each asparagus stalk. You'll want to remove 1-2 inches from the bottom.
Placed the trimmed asparagus on a rimmed baking sheet, drizzle with olive oil and season with lemon zest, minced garlic, onion powder, salt and pepper.
Place the seasoned asparagus in the air fryer basket and cook for 5-6 minutes. Transfer the asparagus to a plate, squeeze lemon juice and serve.
