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

1. Preheat Oven: Preheat your oven to 400°F (200°C).
2. Prepare Chicken: If needed, pound the chicken breasts to an even thickness for uniform cooking.
3. Set Up Breading Station: In one bowl, place the all-purpose flour. In a second bowl, beat the eggs. In a third bowl, mix breadcrumbs, grated Parmesan cheese, garlic powder, salt, pepper, and Italian herbs.
4. Coat the Chicken: Dredge each chicken breast in flour, shaking off any excess. Next, dip in the beaten eggs, allowing the excess to drip off. Finally, coat the chicken in the breadcrumb mixture, pressing gently to adhere.
5. Heat Olive Oil: In a large skillet, heat olive oil over medium-high heat.
6. Sear the Chicken: Once the oil is hot, add the breaded chicken breasts. Sear for 3-4 minutes on each side until golden brown.
7. Bake Chicken: Transfer seared chicken to a baking dish. Bake in the preheated oven for 15-20 minutes or until the internal temperature reaches 165°F (74°C).
8. Serve: Optional—heat marinara sauce for serving alongside the chicken.
9. Garnish: If desired, sprinkle fresh parsley over the chicken before serving.
