Season wings with garlic salt and black pepper.

Preheat air fryer to 400 degrees for 3 minutes then spray the basket with non-stick cooking spray. In a single layer, place the wings in the basket and spray with cooking spray. Set the timer for 15 minutes. After 10 minutes, flip the wings and spray the other side. Air fry 10 minutes longer or until wings are golden brown, and a meat thermometer reaches 180 degrees.

In a small pot, melt the butter and garlic.

Toss warm wings with garlic butter and Parmesan cheese. Serve warm or room temperature.
