01 - Preheat the air fryer to 400°F for 3 minutes before starting.
02 - Pat the chicken breasts dry with paper towels. If thick, pound to even thickness of about 3/4 inch for uniform cooking.
03 - In a shallow bowl, whisk together eggs and milk until fully combined.
04 - In another shallow bowl, combine panko, parmesan, garlic powder, Italian seasoning, paprika, salt, and pepper. Mix thoroughly.
05 - Dip each chicken breast into the egg mixture, coating completely, then press into the parmesan breadcrumb mixture, ensuring an even, thick crust adheres to all sides.
06 - Lightly spray both sides of the coated chicken breasts with olive oil spray to promote golden crisping.
07 - Arrange chicken breasts in a single layer in the air fryer basket. Cook in batches if necessary to avoid overcrowding.
08 - Air fry for 9 minutes at 400°F until the bottom crust begins to golden.
09 - Flip the chicken, spray again lightly with oil, and air fry for another 7 to 9 minutes until the crust is golden brown and the internal temperature reaches 165°F.
10 - Let the chicken rest for 3 minutes before slicing and serving to allow juices to redistribute.
