Yes, you can bread rather than just season your air fryer chicken breast but this will increase the calories and the cooking time. I would also spray the breasts with olive or avocado oil after breading and cook at a lower temp for a longer period of time so the batter doesn't burn before the chicken is cooked. As always when using the air fryer for breaded recipes use a 2-step dry breading rather than a wet batter. This will allow you to get a crispy result without having the breading misshape and even come off as the hot air circulates.
