Preheat your oven to 400°F (200°C).
Flatten the chicken breasts to ensure even cooking.
Season the chicken with salt and pepper.
Set up a breading station with flour, beaten eggs, and breadcrumbs mixed with Parmesan.
Dredge each chicken breast in flour, dip in eggs, and coat with breadcrumbs.
Heat olive oil in a skillet over medium heat.
Fry the breaded chicken until golden brown, about 4-5 minutes per side.
Place the fried chicken in a baking dish.
Top each piece with marinara sauce and mozzarella cheese.
Bake in the oven for 15 minutes, or until the cheese is bubbly and golden.
