Preheat your oven to 375°F.
Flatten the chicken breasts using a mallet for even coating.
Mix breadcrumbs, panko, and grated Parmesan in a shallow dish.
Add salt and pepper to taste.
Dredge the chicken in flour, dip in beaten eggs, and coat with the breadcrumb mixture.
Ensure each piece is well-covered.
Heat olive oil in a skillet over medium heat.
Cook the chicken until golden brown, approximately 4 minutes per side.
Transfer chicken to a baking dish.
Pour tomato sauce over each piece and top with mozzarella cheese.
Bake in the preheated oven for 15-20 minutes until the cheese is melted and bubbly.
Garnish with fresh basil before serving.
