Prepare the breading station: Place flour in one shallow dish. Whisk eggs in a second dish. In a third dish, combine Panko breadcrumbs, 1/4 cup of the grated Parmesan cheese, garlic powder, oregano, salt, and pepper.
Dredge each chicken cutlet first in the flour, shaking off excess. Dip it into the egg mixture, letting excess drip off. Finally, press the cutlet firmly into the breadcrumb mixture to coat both sides completely.
Preheat your air fryer to 380°F (195°C) for 3 minutes.
Lightly spray the air fryer basket with olive oil spray. Place the breaded chicken cutlets in a single layer in the basket, ensuring they do not overlap. Spray the tops of the cutlets lightly with olive oil spray.
Air fry for 10 minutes. Flip the cutlets carefully. Air fry for another 5 to 7 minutes, or until the internal temperature reaches 165°F (74°C).
Remove the chicken from the air fryer. Top each cutlet with marinara sauce and a slice of mozzarella cheese, then sprinkle with the remaining 1/4 cup of Parmesan cheese.
Return the chicken to the air fryer basket. Cook at 380°F (195°C) for 2 to 3 minutes, just until the cheese is melted and bubbly.
Garnish with fresh parsley before serving.
Notes
For a lower-carb option, substitute Panko breadcrumbs with almond flour mixed with grated Parmesan cheese.
If your air fryer basket is small, cook the chicken in batches to maintain crispiness.
Do not skip spraying the breading with oil; this helps it brown and crisp up properly.
