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

1. Preheat the Oven: Set your oven to 375°F (190°C) and prepare a baking dish by lightly greasing it with olive oil.
2. Prepare the Coatings: In a shallow bowl, mix the grated Parmesan cheese, breadcrumbs, garlic powder, onion powder, paprika, salt, and black pepper.
3. Prepare the Egg Mixture: In another bowl, whisk together the eggs and milk until well combined.
4. Coat the Chicken: Dip each chicken breast into the egg mixture, allowing any excess to drip off. Then, coat thoroughly with the breadcrumb mixture, pressing to adhere.
5. Arrange on Baking Dish: Place the coated chicken breasts into the prepared baking dish. Make sure they are not crowded.
6. Drizzle Olive Oil: Lightly drizzle the tops of the chicken with olive oil for an extra crispy texture.
7. Bake: Place the baking dish in the preheated oven and bake for 25-30 minutes or until the chicken is cooked through and the tops are golden brown.
8. Check for Doneness: Use a meat thermometer to ensure the internal temperature of the chicken reaches 165°F (75°C).
9. Garnish: Once out of the oven, sprinkle with freshly chopped parsley for an added pop of color and flavor.
10. Rest: Allow the chicken to rest for a few minutes before serving to retain its juices.
