Step 1

Trim the chewy ends off the asparagus, about an inch or two from the bottom, either cutting them with a sharp knife or snapping with your hands.

Step 2

Spray the bottom of the air fryer with olive oil.

Step 3

Place the asparagus in the air fryer, in a single layer as much as possible (it's okay if some overlap a little though), and spray lightly with olive oil. Sprinkle with salt and pepper.

Step 4

Air fry at 400 degrees F for 7-10 minutes, until crisp but not blackened and burned. Thin pieces will take only 7 minutes or so, while thicker pieces could take 10 or even 11 minutes, depending on their size. Check them often after 7 minutes to make sure the asparagus does not burn.

Step 5

Serve immediately, sprinkling with some vegan parmesan, if desired. Store leftover asparagus in the refrigerator for 2-3 days, and reheat in the air fryer for about 2 minutes to re-crisp.
