Preparing Baked Chicken Parmesan can be effortless if you follow these steps:

1. Preheat the Oven: Set your oven to 400°F (200°C) and prepare a baking dish by greasing it lightly.
2. Prep the Chicken: Place the chicken breasts between two sheets of plastic wrap and pound them to an even thickness for uniform cooking.
3. Prepare the Breading: In a bowl, mix breadcrumbs, grated Parmesan cheese, garlic powder, onion powder, oregano, salt, and pepper.
4. Beat the Eggs: In a separate bowl, beat the eggs until well mixed.
5. Coat the Chicken: Dip each chicken breast into the egg mixture, allowing excess to drip off, then coat it in the breadcrumb mixture, pressing gently to adhere.
6. Arrange in Baking Dish: Place the breaded chicken in the prepared baking dish, spaced evenly apart.
7. Bake: Bake in the preheated oven for 20-25 minutes or until the chicken is cooked through and golden brown.
8. Add Sauce and Cheese: Remove the chicken from the oven, spoon marinara sauce over each piece, and top with shredded mozzarella cheese.
9. Final Bake: Return to the oven and bake for an additional 5-10 minutes, or until the cheese is melted and bubbly.
10. Cool: Let the dish cool for a few minutes before serving.
