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

1. Preheat the Oven: Begin by preheating your oven to 425°F (220°C).
2. Prepare Chicken: Place the chicken breasts between two sheets of plastic wrap and pound them to an even thickness using a meat mallet.
3. Set Up Breading Station: In a shallow dish, combine the breadcrumbs, grated Parmesan cheese, garlic powder, onion powder, Italian seasoning, salt, and pepper. In another shallow dish, place the flour, and in a third dish, beat the eggs lightly.
4. Bread the Chicken:
– Dredge each chicken breast in the flour, shaking off the excess.
– Dip it into the beaten eggs, ensuring it’s fully coated.
– Finally, coat the chicken in the breadcrumb mixture, pressing it on firmly to help it stick.
5. Arrange on Baking Sheet: Place the breaded chicken breasts on a lightly greased baking sheet.
6. Bake: Bake in the preheated oven for 20-30 minutes, or until the chicken is golden brown and cooked through. An internal temperature of 165°F (75°C) is ideal.
7. Add Marinara Sauce (Optional): If desired, add marinara sauce on top of each chicken breast during the last 5 minutes of baking. Sprinkle additional Parmesan cheese on top for extra flavor.
8. Garnish and Serve: Once done, remove the chicken from the oven and let it rest for a few minutes before serving. Optionally, garnish with chopped parsley for a fresh finish.
