Creating Baked Chicken Parmesan is straightforward if you follow these simple steps:

1. Preheat the Oven: Begin by preheating your oven to 400°F (200°C). This ensures even cooking.
2. Prepare Chicken: Place the chicken breasts between two pieces of plastic wrap or parchment paper. Pound them to an even thickness, about 1-inch thick for even cooking. Season both sides with salt and pepper.
3. Set Up Breading Station: In one bowl, whisk the eggs. In a second bowl, combine the breadcrumbs, grated Parmesan cheese, garlic powder, and dried oregano.
4. Coat Chicken: Dip each chicken breast first in the egg, letting any excess drip off, followed by coating it in the breadcrumb mixture. Press down slightly to ensure the coating sticks.
5. Arrange on Baking Sheet: Line a baking sheet with parchment paper or lightly grease it. Place the breaded chicken breasts on the sheet, ensuring they don’t touch.
6. Bake Chicken: Bake in the preheated oven for 20 minutes until the chicken is cooked through and golden brown.
7. Add Marinara and Cheese: Remove the baking sheet from the oven. Spoon marinara sauce generously over each chicken breast, then top with shredded mozzarella cheese.
8. Return to Oven: Bake for an additional 10-15 minutes, or until the cheese has melted and is bubbly.
9. Prepare to Serve: Once done, remove from the oven and let the chicken rest for a few minutes.
10. Garnish: If desired, garnish with fresh basil leaves to add a beautiful touch and extra flavor.
