Prepare the Chicken: If the chicken breasts are thick, pound them to an even thickness for uniform cooking. Season both sides with salt and pepper.
Set Up Breading Station: In one shallow bowl, whisk together the egg and milk. In another bowl, combine breadcrumbs, Parmesan cheese, garlic powder, Italian seasoning, salt, and pepper.
Bread the Chicken: Dip each chicken breast in the egg mixture, allowing excess to drip off. Then coat in the breadcrumb mixture, pressing firmly to adhere.
Air Fry the Chicken: Preheat the air fryer to 400°F (200°C). Lightly spray the basket with cooking spray. Place the breaded chicken breasts in the basket in a single layer, making sure they aren’t touching. Spray the tops lightly with olive oil.
Cook: Air fry for 10-15 minutes, flipping halfway through, until the chicken is golden brown and reaches an internal temperature of 165°F (75°C).
Serve: Let the chicken rest for a few minutes before slicing. Serve with your favorite sides and enjoy!
