Make the sauce by adding all of the sauce ingredients to a bowl and mixing well.
Preheat air fryer to 400° Fahrenheit. Even if it doesn't have a preheat function, preheat it for a few minutes.
If desired, spray your air fryer basket with cooking oil. Place the chicken breasts in the basket.
Set the breasts to cook for a total of 30 minutes (you'll flip them after 15 minutes).
After 15 minutes of cooking, flip the breasts.
Cook for another 10-20 minutes, or until the chicken reaches an internal temperature of 165° in the thickest part of the breast.
In the last few minutes of cooking, brush the sauce on both sides of the breasts. Note: Don't brush the sauce on too early, as it will burn after a few minutes. If you don't want to risk it burning, simply brush the sauce on after the chicken is completely cooked.
Remove the chicken and serve.
