Preheat your oven to 400°F (200°C). Lightly grease a 9x13-inch baking dish.
Season the chicken cutlets on both sides with salt and pepper.
Set up a breading station with three shallow bowls. Place the flour in the first bowl, the beaten eggs in the second, and mix the breadcrumbs with 0.25 cup of the Parmesan cheese in the third.
Dredge each chicken cutlet in the flour, shaking off any excess. Dip into the eggs, then press into the breadcrumb mixture to coat completely.
Heat the olive oil in a large skillet over medium-high heat. Fry the breaded chicken cutlets until golden brown and crispy, about 3 to 4 minutes per side. Transfer the browned chicken to the prepared baking dish.
Spoon marinara sauce over each chicken cutlet. Top evenly with the shredded mozzarella cheese and the remaining 0.25 cup of Parmesan cheese.
Bake in the preheated oven for 10 to 15 minutes, or until the cheese is melted and bubbly and the chicken reaches an internal temperature of 165°F (74°C).
Garnish with fresh chopped basil before serving.
Notes
