Drizzle the asparagus with the olive oil and season with garlic salt, salt, and pepper as desired.
Spray the bottom of the air fryer pan with non-stick cooking spray for easy clean up.
Place the asparagus in a single layer in the bottom of the air fryer.
Set the air fryer to 400℉ and set the timer for 8 minutes. If asparagus is thin, start checking for doneness at 6 minutes.
Notes
You could substitute garlic salt with garlic powder, if desired.When asparagus is done cooking, it is delicious if you squeeze the juice from 1/2 a lemon on top and sprinkle with a little big of Parmesan cheese.If your air fryer is smaller, you might have to cook your bunch of asparagus in separate batches.
