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

1. Prepare Chicken: Start by preheating your oven to 400°F (200°C). Flatten each chicken breast to an even thickness for uniform cooking.
2. Set Up Breading Stations: In one shallow bowl, place the flour. In another bowl, whisk together the eggs and milk. In a third bowl, combine the Parmesan cheese, breadcrumbs, garlic, Italian seasoning, salt, and pepper.
3. Bread the Chicken: First, dredge each chicken breast in flour, shaking off the excess. Next, dip it into the egg mixture, then coat it thoroughly in the Parmesan breadcrumb mixture.
4. Fry the Chicken: In a large skillet, heat the butter over medium heat. Once hot, add the breaded chicken breasts. Cook for 4-5 minutes on each side until golden brown and cooked through.
5. Bake the Chicken: Transfer the browned chicken to a baking dish. Bake in the preheated oven for 10-15 minutes to ensure thorough cooking.
6. Check Doneness: Use a meat thermometer to confirm that the internal temperature reaches 165°F (75°C).
7. Garnish: Once done, remove the chicken from the oven and let it rest for a few minutes. Garnish with freshly chopped parsley before serving.

These steps will guide you in creating this incredible dish effortlessly.
