Follow these simple steps to create your own Longhorn Steakhouse Parmesan Chicken:

1. Preheat Oven: Begin by preheating your oven to 400°F (200°C).
2. Prepare Chicken: If the chicken breasts are thick, pound them to an even thickness for uniform cooking.
3. Set Up Breading Stations: Place flour in one bowl, beaten eggs in another, and a mixture of breadcrumbs, Parmesan cheese, garlic powder, onion powder, smoked paprika, salt, and pepper in a third bowl.
4. Coat the Chicken: Dredge each chicken breast in flour, ensuring it’s fully coated. Shake off any excess flour.
5. Dip in Eggs: Next, dip the floured chicken into the beaten eggs, allowing any extra to drip off.
6. Final Coating: Press each chicken breast into the breadcrumb mixture until evenly coated.
7. Heat Oil: In a large skillet, heat olive oil over medium heat. Make sure the oil is hot but not smoking.
8. Cook Chicken: Add the coated chicken breasts to the skillet. Cook for about 4-5 minutes on each side, or until they are golden brown and cooked through.
9. Bake: Transfer the skillet to the preheated oven. Bake for an additional 10-15 minutes for added crispiness.
10. Add Marinara: Once cooked, remove the skillet from the oven. Spoon marinara sauce over the chicken, and sprinkle extra Parmesan cheese on top if desired.
11. Garnish and Serve: Optionally, garnish with fresh basil or parsley before serving.
