Baked Chicken Parmesan is easy to prepare if you follow these straightforward steps:

1. Preheat Oven: Preheat your oven to 400°F (200°C).
2. Prepare Chicken: Lightly season the chicken breasts with salt and pepper on both sides.
3. Create Breading Stations: In one bowl, place the flour. In another bowl, beat the eggs. In a third bowl, mix the breadcrumbs, garlic powder, onion powder, oregano, and Parmesan cheese.
4. Coat Chicken: Dredge each chicken breast in flour, then dip it in the egg, followed by coating it with the breadcrumb mixture. Ensure each piece is well coated.
5. Arrange on Baking Sheet: Place the breaded chicken breasts on a baking sheet lined with parchment paper or lightly greased.
6. Bake Chicken: Bake in the preheated oven for 20 minutes.

8. Return to Oven: Put the chicken back in the oven and bake for an additional 10-15 minutes, until the cheese is bubbly and golden.
9. Check Doneness: Make sure the chicken reaches an internal temperature of 165°F (75°C).
