Preheat your oven to 400°F (200°C).
Place the flour in a shallow dish and season with salt and pepper.
In another dish, beat the eggs.
In a third dish, spread the breadcrumbs.
Dip each chicken breast into the flour, shaking off the excess.
Next, dip the chicken into the beaten eggs.
Finally, coat the chicken in breadcrumbs.
Heat olive oil in a skillet over medium heat.
Fry the chicken until golden brown on both sides, about 5 minutes per side.
Transfer the chicken to a baking dish, top with marinara sauce, mozzarella, and Parmesan.
Bake in the preheated oven for 20 minutes or until the cheese is bubbly.
