Creating Longhorn Steakhouse Parmesan Chicken at home is straightforward. Follow these easy steps to whip up this delicious meal:

1. Preheat Oven: Preheat your oven to 375°F (190°C) and lightly grease a baking dish.
2. Prepare Chicken: Pat the chicken breasts dry with a paper towel. Place them between two sheets of plastic wrap and pound them to an even thickness for consistent cooking.
3. Mix Breading Ingredients: In a shallow dish, combine the grated Parmesan cheese, breadcrumbs, garlic powder, paprika, salt, and black pepper.
4. Prepare Egg Mixture: In another bowl, whisk together the eggs and milk until well combined.
5. Coat Chicken: Dip each chicken breast into the egg mixture, allowing excess to drip off. Then coat it in the breadcrumb mixture, pressing firmly to adhere.
6. Arrange in Baking Dish: Place the coated chicken breasts in the prepared baking dish, ensuring they are not crowded.
7. Bake: Bake for 25-30 minutes, or until the chicken is golden brown and reaches an internal temperature of 165°F (75°C).
8. Add Marinara (Optional): If desired, spoon marinara sauce over each piece of chicken for added flavor and moisture during the last 5 minutes of baking.
9. Garnish: Once done, remove the chicken from the oven and let it rest for a few minutes. Sprinkle with fresh parsley for a pop of color.
10. Serve: Cut into the chicken to reveal the juicy interior and enjoy your homemade Longhorn Steakhouse-inspired meal!
