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