Preheat your oven to 400°F (200°C) and spray a baking dish with nonstick cooking spray.
Set up three shallow dishes: one with flour seasoned with salt and pepper, one with beaten eggs, and one with seasoned breadcrumbs.
Coat each chicken breast in flour, dip in egg wash, then roll in breadcrumbs until fully covered.
Place the coated chicken in the baking dish, drizzle with olive oil, and bake for 25-30 minutes until golden brown.
Remove from oven, spoon marinara sauce over each piece, top with mozzarella and Parmesan cheese, and return to the oven for an additional 10-15 minutes until bubbly.
Garnish with fresh basil before serving.
