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

1. Preheat Your Oven: Begin by preheating your oven to 400°F (200°C). This prepares it for cooking the chicken perfectly.
2. Prep Chicken: Take the chicken breasts and pound them to an even thickness, making them uniform for cooking.
3. Season the Flour: In a shallow dish, mix the flour with a pinch of salt. This gives the chicken an extra layer of flavor.
4. Prepare the Egg Mixture: In another shallow bowl, whisk together the eggs and milk until blended evenly.
5. Combine Breadcrumbs: In a third dish, mix the Italian seasoned breadcrumbs, grated Parmesan cheese, garlic powder, onion powder, and black pepper.
6. Coat Chicken: Dip each chicken breast into the flour, shaking off the excess. Then, coat it in the egg mixture, and finish with the breadcrumb mixture, pressing down to adhere well.
7. Heat Oil: In a large skillet, heat the olive oil over medium heat. Make sure it’s hot enough to sizzle when you add the chicken.
8. Cook the Chicken: Carefully place the breaded chicken breasts in the hot oil. Cook for 4-5 minutes on each side until golden brown.
9. Bake in the Oven: Once browned, transfer the chicken to a baking dish and place it in the preheated oven. Bake for 15-20 minutes or until the chicken reaches an internal temperature of 165°F (75°C).
10. Garnish and Serve: After baking, garnish with fresh parsley and serve hot. Pair it with sides of your choice, such as mashed potatoes or a fresh salad.
