To add a touch of sweetness and tanginess, try making honey mustard chicken breasts in the air fryer. In a bowl, mix together honey, Dijon mustard, garlic powder, salt, and pepper. Coat the chicken breasts with the honey mustard mixture. Preheat the air fryer to 375°F (190°C). Place the chicken breasts in the air fryer basket and cook for 15-18 minutes, flipping halfway through. The result will be juicy chicken breasts with a sticky and flavorful honey mustard glaze.
