Preheat air fryer to 400F. Toss asparagus with oil, seasonings, and parmesan. Spread out evenly in the air fryer basket.
12 ounces asparagus , 1 tablespoon oil , ½ teaspoon garlic powder, ½ teaspoon onion powder, salt and pepper taste , 2 tablespoon grated parmesan
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!

Notes
To store: Store in the refrigerator and reheat in the microwave. To freeze: You could freeze this asparagus after cooking it for sure, up to 3 months in an air-tight container. You may not want to, though. The texture is likely to be akin to canned asparagus when you defrost it. Very soggy and kind of stringy. But some people don't mind freezer food. I'm more picky!
