Preheat air fryer to 400F. Toss asparagus with oil, seasonings, and parmesan. Spread out evenly in the air fryer basket. Cook for 3-10 minutes, depending on the thickness of the spears. Thinner spears will cook in 3 minutes. Thicker could take up to 12 minutes. I recommend checking them every 3 minutes or so!
