For a sweet and tangy flavor, try this honey mustard chicken breast recipe. In a small bowl, mix together honey, Dijon mustard, garlic powder, salt, and pepper. Coat the chicken breasts with the honey mustard mixture and let them marinate for 30 minutes. Preheat the air fryer to 375°F (190°C) and cook the chicken for 12-15 minutes, flipping halfway through, until it reaches an internal temperature of 165°F (74°C). Serve with a side of steamed rice or roasted potatoes.
