Dump frozen chicken wings into air fryer basket. It's ok if they overlap because they will shrink as they cook. The amount you can cook at once will depend on the size of your air fryer.
Cook at 350˚F/177˚C for 10 minutes to thaw.
Season both sides of chicken with garlic salt and pepper.
Cook at 380˚F/193˚C for 25 minutes, flipping halfway through cooking time.
Coat chicken with your favorite BBQ sauce.
Cook at 400˚F/204˚C for 5 minutes. Serve warm and enjoy!
Notes
My 4-qt air fryer fits just over 2 pounds (almost 2.5 pounds) of frozen wings at one time.
