Prep the chicken: If using breasts, slice them horizontally into cutlets.
Pound to an even 1/2-inch thickness between two sheets of parchment. Pat dry and season both sides with salt and pepper.
Set up dredging station: Place flour in one shallow dish. Beat eggs in a second dish.
In a third dish, mix breadcrumbs, Parmesan, garlic powder, and paprika.
Coat the cutlets: Dredge each piece in flour (shake off excess), dip in egg, then press into the breadcrumb mixture until fully coated. Place on a tray and let sit 5 minutes so the coating adheres.
Preheat the air fryer: Heat to 390°F (200°C) for 3–5 minutes. Lightly spray the basket with oil.
Air fry the schnitzels: Arrange cutlets in a single layer without overlapping.
Lightly spray tops with oil. Cook for 6–8 minutes, flip, spray again, and cook another 4–6 minutes until golden and the internal temperature reaches 165°F (74°C).
Add the mozzarella: Top each schnitzel with 1–2 slices of fresh mozzarella. Return to the air fryer for 1–2 minutes until the cheese just melts.
Finish with Caprese toppings: Transfer to plates.
Top with tomato slices and basil. Drizzle with a little olive oil and a swirl of balsamic glaze. Add a pinch of salt and pepper to the tomatoes.
Serve: Plate with a handful of arugula or a simple salad.
A squeeze of lemon on the schnitzel brightens everything.
