Place the chicken breasts between two sheets of plastic wrap and pound them to an even thickness of about 1/2 inch.
In a shallow dish, place the flour. In another dish, beat the eggs with a pinch of salt and pepper. In a third dish, mix the breadcrumbs with 1/2 cup of grated Parmesan cheese, oregano, and garlic powder.
Dredge each chicken breast in flour, shaking off the excess. Then dip into the egg mixture, allowing any excess to drip off. Finally, coat the chicken in the breadcrumb mixture, pressing gently to ensure the crumbs adhere well. Repeat for both chicken breasts.
In a large skillet, heat about 1/4 inch of olive oil over medium heat. Once hot, carefully add the breaded chicken. Cook for about 5-7 minutes on each side or until golden brown and cooked through (internal temperature should reach 165°F).
Preheat your oven to 375°F (190°C). Place the fried chicken breasts in a baking dish. Spoon marinara sauce evenly over each piece. Sprinkle the remaining Parmesan cheese and top with shredded mozzarella cheese.
Bake in the preheated oven for about 15 minutes, or until the cheese is bubbly and lightly golden. For an extra bubbly effect, you can broil for an additional 2-3 minutes—keep an eye to prevent burning.
Once out of the oven, let it rest for a few minutes. Garnish with fresh basil leaves before serving.
Notes
For extra crispiness, ensure the oil is hot before frying.
