The chicken breast can be seasoned with salt, pepper, or other seasonings that you prefer.
Coat the air fryer basket with olive oil cooking spray.
Place chicken in the air fryer basket and cook at 390*F for 6 minutes.
Open the air fryer and carefully turn the chicken, coat with additional spray if needed, and cook for an additional 6-8 minutes or until it reaches an internal temperature of at least 165*F.
Remove and serve.
Notes
All air fryers heat differently, so it may need a few extra minutes to reach the correct internal temperature.
