Prep the oven or air fryer: For oven baking, preheat to 425°F (220°C) and line a sheet pan with parchment. Place a wire rack on top if you have it.
For air fryer, preheat to 400°F (205°C) for 3–5 minutes.
Pat the chicken dry: Use paper towels to remove excess moisture. Dry chicken equals crispier crust.
Set up three bowls: In one, add flour with a pinch of salt and pepper. In the second, whisk eggs and milk. In the third, mix panko, Parmesan, garlic powder, onion powder, paprika, Italian seasoning, 1/2 teaspoon salt, and black pepper.
Coat the chicken: Dredge each piece in flour (shake off extra), dip in egg, then press firmly into the panko-Parmesan mixture. Press to help the crumbs stick and fully coat all sides.
Arrange on the pan or air fryer basket: Space them out so air can circulate.
For baking, drizzle or brush lightly with oil. For air frying, spray both sides with oil spray.
Cook: Oven: Bake 14–18 minutes, flipping halfway. Add a light drizzle of oil after flipping if needed.
They’re done when the coating is golden and the internal temp reaches 165°F (74°C).
Air fryer: Cook 9–12 minutes, flipping at 6 minutes, until golden and cooked through.
Optional extra crisp: Broil for 1–2 minutes at the end, watching closely to avoid burning.
Rest and serve: Let sit 3 minutes to keep the juices in. Squeeze lemon over the top, sprinkle parsley, and serve with your favorite dips.
