Preheat your oven to 425°F (220°C).

Place the chicken breasts between two pieces of plastic wrap and pound them to an even thickness of about 1/2 inch.

Season the chicken with salt and pepper.

Prepare three shallow bowls: one with flour, one with beaten eggs, and one with a mixture of breadcrumbs and Parmesan cheese.

Dredge each chicken piece in the flour, dip in the egg, and coat in the breadcrumb mixture.

Heat olive oil in a large oven-safe skillet over medium-high heat. Sear the chicken until golden brown on both sides, about 2-3 minutes per side.

Spread marinara sauce over the seared chicken and top with shredded mozzarella cheese.

Transfer the skillet to the oven and bake for 10-15 minutes or until the cheese is bubbly and the chicken is cooked through.

Garnish with fresh basil and serve hot.
