Creating Longhorn Steakhouse Parmesan Chicken is a straightforward process. Follow these simple steps to achieve a delectable result:

1. Preheat the Oven: Start by preheating your oven to 400°F (200°C). This ensures the chicken cooks evenly and achieves a crispy exterior.

2. Prepare the Breading Station: In three separate shallow bowls, set up your breading stations. In the first bowl, add flour. In the second bowl, beat the eggs. In the third bowl, mix the Parmesan cheese, breadcrumbs, garlic powder, Italian seasoning, salt, and pepper.

3. Coat the Chicken: Take each chicken breast and dip it first in the flour, then into the beaten eggs, and finally into the Parmesan-breadcrumb mixture. Press the coating firmly onto the chicken to ensure it adheres well.

4. Arrange on Baking Sheet: Place the coated chicken breasts on a greased baking sheet. Make sure they are not crowded to allow even cooking.

5. Bake: Bake the chicken in the preheated oven for 25-30 minutes or until the chicken reaches an internal temperature of 165°F (75°C) and the breading is golden brown.

6. Prepare the Sauce: While the chicken is baking, prepare the sauce. In a small bowl, combine mayonnaise and lemon juice. Mix well and set aside.

7. Serve: Once the chicken is cooked through, remove it from the oven. Let it rest for a few minutes before serving.

8. Drizzle the Sauce: Serve the chicken warm and drizzle the creamy mayonnaise sauce over the top for added flavor.

These straightforward steps will help you recreate the mouthwatering Longhorn Steakhouse Parmesan Chicken with ease and satisfaction.
