Prep the chicken. Slice each chicken breast horizontally to create thin cutlets.
Pat dry with paper towels for better browning. If needed, lightly pound to an even 1/2-inch thickness.
Season. Sprinkle both sides with a pinch of salt and pepper. This simple step boosts flavor all the way through.
Set up the dredging station. Place flour in one shallow bowl.
Beat eggs in a second bowl. In a third bowl, mix breadcrumbs, Parmesan, garlic powder, onion powder, oregano, 1/2 teaspoon salt, and black pepper.
Coat the chicken. Dredge each cutlet in flour (shake off excess), dip in egg, then press into the breadcrumb mixture until fully coated. Set on a plate.
Preheat the air fryer. Heat to 380°F (193°C) for 3–5 minutes.
A hot basket helps the coating turn crisp fast.
Spray and arrange. Lightly spray the air fryer basket. Place cutlets in a single layer without overlapping. Spray the tops of the cutlets lightly with oil.
Air fry the first side. Cook at 380°F (193°C) for 6–7 minutes until the coating sets and starts to brown.
Flip and finish. Carefully flip, spray again, and cook 4–6 more minutes.
The chicken should reach an internal temp of 165°F (74°C) and look golden brown.
Add sauce and cheese. Spoon about 2 tablespoons marinara over each cutlet, then top with a generous sprinkle of mozzarella and a little extra Parmesan.
Melt. Air fry at 360°F (182°C) for 2–3 minutes, just until the cheese is melted and bubbly.
Rest and serve. Let the chicken rest for 2 minutes so the coating stays crisp. Garnish with chopped basil or parsley. Serve with pasta, bread, or salad.
