01 - Preheat air fryer to 400°F for 5 minutes.
02 - Pat chicken breasts dry with paper towels. If thick, pound to even 3/4-inch thickness using a meat mallet.
03 - Arrange three shallow bowls: first with flour, second with beaten eggs, third with panko mixture (combine breadcrumbs, Parmesan, garlic powder, paprika, salt, and pepper).
04 - Dredge each chicken breast in flour, shaking off excess. Dip into egg wash, then press firmly into panko mixture to coat evenly on all sides.
05 - Lightly spray both sides of each breaded chicken breast with cooking oil.
06 - Place chicken in single layer in air fryer basket without overlapping. Air fry at 400°F for 7 minutes.
07 - Flip chicken breasts, spray lightly with oil again, and air fry for additional 6-8 minutes until golden brown and internal temperature reaches 165°F.
08 - Let chicken rest for 2-3 minutes before serving to allow juices to redistribute.
