Pat wings dry and season lightly with salt and pepper.
Set the air fryer to 375 and cook the wings for 25 minutes, flipping them over at about the last 5 minute mark.
Bump the heat up to 400 and continue cooking for 5 more minutes to get them nice and crispy. While the wings cook for the last 5 minutes, melt the butter.
In a separate bowl mix the Parmesan, ranch seasoning and garlic powder in a large bowl.
Once wings are done, toss them in the melted butter then in the Parmesan mixture.
