Creating Longhorn Steakhouse Parmesan Chicken at home can be a straightforward endeavor when following these easy steps:

1. Preheat the Oven: Begin by preheating your oven to 400°F (200°C).
2. Prepare Baking Sheet: Line a baking sheet with parchment paper or spray it with cooking spray to prevent sticking.
3. Prepare Breading Station: Set up a breading station with three shallow dishes. In the first dish, beat the eggs. In the second dish, combine the breadcrumbs, Parmesan cheese, garlic powder, onion powder, salt, and pepper. The third dish can remain empty.
4. Coat Chicken: Take each chicken breast and first dip it into the beaten eggs, ensuring each piece is well coated.
5. Dredge in Breading Mixture: Next, transfer the chicken breasts to the breadcrumb mixture, pressing down to coat thoroughly.
6. Arrange on Baking Sheet: Place the coated chicken breasts on the prepared baking sheet, ensuring they have some space between each piece.
7. Drizzle with Oil: Lightly drizzle olive oil over the chicken to help it crisp up during cooking.
8. Bake: Place the baking sheet in the preheated oven and cook for 20–25 minutes or until the chicken reaches an internal temperature of 165°F (74°C).
9. Check Doneness: Use a meat thermometer to ensure the chicken is fully cooked; the juices should run clear.
10. Serve Hot: Remove the chicken from the oven and let it rest for a few minutes before serving. Garnish with fresh parsley if desired.
