Set up your breading station in three shallow dishes. In one dish, prepare the dry batter mixture by combining the cornstarch, garlic powder and Italian seasoning. In another dish, beat an egg until smooth. In the last dish, combine Italian-style breadcrumbs and grated Parmesan cheese.
Prepare the chicken breasts. Slice the boneless, skinless chicken breasts horizontally without cutting all the way through to create a butterfly cut. Then, spread both sides and flatten the chicken breasts with the flat side of the meat mallet.
Next, season the chicken breast filets with paprika and salt.
Preheat the air fryer to 400°F (204°C).
Bread the tenderized chicken breasts. First, dredge them in the dry batter, shaking off any excess. Then, dip each chicken breast into the beaten egg. Lastly, coat them in the breading mixture, pressing gently to help the crumbs adhere. Repeat the process until all chicken breasts are breaded, and place them on a wire rack or plate.
Air fry chicken parm for 10 minutes. Start by carefully transferring the breaded chicken Parmesan in the preheated air fryer, then spray them with high-heat cooking oil. Cook both sides for 5 minutes.
After 10 minutes, add 2 tablespoons of marinara sauce and mozzarella cheese. Continue air frying chicken Parmesan for 2-3 minutes or until the cheese is melted and bubbly. To ensure that the chicken is fully cooked, the internal temperature should reach 165°F (74°C) or higher.
Serve your air fryer chicken parm! Top it off with chopped parsley. Enjoy!
