Set up three shallow dishes: one with flour, one with beaten eggs, and one with breadcrumbs mixed with 0.5 cup Parmesan cheese, salt, and pepper.
Dredge each chicken cutlet first in flour, then dip in the beaten eggs, and finally coat thoroughly with the breadcrumb mixture.
Heat olive oil in a large oven-safe skillet over medium-high heat. Fry the chicken cutlets for about 3-4 minutes per side until golden brown and cooked through.
Remove chicken from the skillet and place in a baking dish. Spoon marinara sauce over each cutlet, then top with shredded mozzarella and the remaining 0.25 cup Parmesan cheese.
Bake in the preheated oven for 10-15 minutes, or until the cheese is melted and bubbly and the sauce is heated through.
Garnish with fresh basil leaves, if desired, before serving.
Notes
Serve with your favorite pasta, a side salad, or garlic bread.
