Wash the asparagus and trim the bottom edges off the asparagus (approximately 1 inch).
Brush the olive oil onto the asparagus and season with the salt and pepper.
Place the asparagus in the air fryer basket. Cook at 400 degrees F (do not preheat the air fryer as it may cause the asparagus to be over cooked).
Cook for 3-5 minutes depending on the thickness of your asparagus. Start with 3 minutes and then cook for an additional 1 minute at a time until the asparagus is the tenderness that you prefer.
Remove from the basket once done and enjoy!
Notes
Watch the asparagus closely as it's cook as it doesn't take long to overcook. This is also great topped with fresh lemon juice once it's done cooking!
