NOTE: I have purchased LARGE chicken legs before, and the measurements in this recipe only covered 3 chicken legs and the cook time of 20 minutes was not nearly enough. So reducing the temperature of the air fryer and cooking for a longer period of time may also be necessary if using large chicken legs. (A temperature of 400 degrees may burn the butter/parmesan crust if cooked at a high temp for too long.)
Melt butter in shallow dish and add in parmesan cheese, garlic powder, salt and pepper.
Place chicken legs (in a single layer, do not stack on top of one another) in to air fryer.
Cook on 400 degrees for 20-25 minutes.
Air fryers can be different. Make sure internal temp of chicken legs have reached 165 degrees.
For PLAIN (no garlic parmesan) you can simply cook the legs in the air fryer without the spices and seasonings. NOTE: you may want to coat the legs in a little olive oil to prevent sticking.For BBQ Chicken Legs, see notes in blog post for tips to make them the best!
