Slice each chicken breast in half horizontally to create thinner cutlets.
Place the cutlets between two sheets of plastic wrap and gently pound them to about 1/2 inch thickness.
Season both sides with salt, pepper, garlic powder, and onion powder.
Set up a breading station: Place the flour in one shallow dish, beat the eggs in a second dish, and combine the breadcrumbs, Parmesan cheese, and chopped basil in a third dish.
Dredge each chicken cutlet in flour, shaking off the excess.
Dip into the beaten eggs, then coat with the breadcrumb mixture, pressing gently to adhere.
In a large skillet, heat the olive oil over medium heat.
Add the breaded chicken cutlets and cook for about 4-5 minutes per side, or until golden brown and cooked through.
Remove the cutlets from the skillet and place them on a baking sheet.
Spoon a little marinara sauce over each cutlet and sprinkle with shredded mozzarella cheese.
Broil in the oven for 2-3 minutes, or until the cheese is melted and bubbly.
Serve immediately with additional marinara sauce on the side.
