Sandwich the chicken beasts between 2 pieces of parchment paper and pound until 1" thin.
Combine breadcrumbs, pork panko and parmesan cheese in a bowl.
In a separate bowl add the egg whites.
Dip the chicken breasts into the egg whites, then into the breadcrumb mixture, coating the whole piece.
Dip back into the egg white and coat piece in breadcrumb mixture for a second time.
Air fry on 390 for approx 15-17 minutes until chicken is cooked through. Flip overhalf way to make sure all breading is getting crispy.
During last 1 minute, add cheese on top of cutlet and let finish baking so cheese is melted onto of the chicken cutlet. Remove once done and set aside.
