Preheat your air fryer at 400°F for 5 minutes.
Spray the hot air fryer basket with olive oil.
Spray one side of how ever many chicken breast cutlets will fit in your air fryer basket until the panko and bread crumbs are damp (I could fit 3). If the crumbs go in dry, they will come out dry, not golden brown and may burn.
Place the chicken breast slices oiled side down into your air fryer basket.
Spray the tops of your chicken with oil until the panko and bread crumbs are damp.
Air Fry at 370°F for 7-8 minutes.
Lightly spray the chicken with oil, flip the chicken, and lightly spray the chicken again.
Air fry at 370°F for another 2-5 minutes, when they are golden brown, and plate the chicken.
Repeat for the rest of the chicken breast slices.
Serve with your tonkatsu sauce you made, veggies and rice.
