Use shallow bowls to create a dredging station by adding egg whites into one shallow bowl and make breadcrumb mixture with Italian seasoning, and ground black pepper into the other shallow bowl. Set both bowls aside.

Preheat your air fryer to 400°F.

Pat dry chicken breasts with paper towels on a cutting board or baking sheet.

Cover chicken with plastic wrap and gently tap with a meat mallet or meat tenderizer so they are all uniform in size, about ¼-inch thick.

Dip each piece of chicken into the egg mixture and then into the breading mixture until each piece is fully coated.

Place the breaded chicken on a baking sheet until all cutlets have been breaded.

Prepare the air fryer basket with cooking spray, then add the chicken pieces in a single layer to allow room for the air to circulate and chicken to evenly cook.

Spray the tops of the pieces of chicken with olive oil spray.
