Creating this Chicken Parmesan is straightforward if you follow these step-by-step instructions:

1. Preheat Oven: Preheat your oven to 400°F (200°C) and prepare a baking dish by lightly greasing it with olive oil or cooking spray.
2. Prep Chicken: Place chicken breasts between two sheets of plastic wrap. Use a meat mallet to pound them to an even thickness for uniform cooking.
3. Season Chicken: Season both sides of the chicken with salt and black pepper.
4. Prepare Breading Station: Set up three bowls: one with flour, one with beaten eggs, and the third with breadcrumbs mixed with oregano and garlic powder.
5. Bread the Chicken: Dredge each chicken breast in flour, shaking off excess. Then dip in beaten eggs, followed by coating with breadcrumbs until well covered.
6. Pan-Fry Chicken: In a large skillet over medium heat, add olive oil. Once hot, add chicken breasts and cook for 5-6 minutes on each side until golden brown and crispy.
7. Transfer to Baking Dish: Place the fried chicken in the greased baking dish, ensuring they are arranged without overlapping.
8. Add Sauce and Cheese: Spoon marinara sauce evenly over each piece of chicken. Top generously with shredded mozzarella and grated Parmesan cheese.
9. Bake: Place the baking dish in the oven and bake for 20 minutes, or until the cheese is bubbly and golden.
10. Rest Before Serving: After taking it out, allow the Chicken Parmesan to rest for 10 minutes. This helps the flavors to meld together and makes it easier to serve.
