Place asparagus into air fryer basket. Spray (or drizzle) with oil, and add a pinch of salt.
Air fry at 380 degrees for 7 to 8 minutes, stopping once to shake the basket for even roasting. Cooking time can vary depending on your air fryer and the thickness of the asparagus. So start checking doneness at about 5 minutes. I like it when they are starting to brown with crispy tips. If the stalks are especially wide, it may take as long as 10 minutes. Remove when they reach your preferred doneness.
Notes
Instead of or in addition to salt, you can season the asparagus with vegan feta cheese, lemon juice, lemon zest, vegan hollandaise sauce, and/or your favorite seasoning salt. I especially like Penzeys' Fox Point seasoning. Storage & reheating instructionsStore any leftovers in a covered container in the refrigerator. It will keep 3 to 5 days.When you’re ready to eat it, throw it back into the air fryer basket. Cook at 380 degrees until warm. Or reheat for 30 to 60 seconds in the microwave.
