11. In a small bowl, mix together Buffalo sauce, melted butter, garlic powder, onion powder, salt, and pepper – this is the marinade.
22. Place the chicken breast in a bowl or resealable bag, pour the marinade over it, and seal. Refrigerate for at least 30 minutes.
33. Preheat the air fryer to 190°C (375°F) – this takes about 3-5 minutes.
44. Remove the chicken from the marinade and place it in the air fryer basket. Cook for 15-18 minutes, flipping halfway through (after 7-9 minutes). Check internal temperature – it should reach 74°C (165°F).
55. Serve immediately, hot, with celery sticks and blue cheese dressing if desired.
