Creating Copycat Longhorn Steakhouse Parmesan Chicken is as easy as following these simple steps:

1. Preheat the Oven: Preheat your oven to 400°F (200°C) to prepare for baking the chicken.

2. Prepare the Coating: In three separate bowls, place the flour, beaten eggs, and a mixture of breadcrumbs and grated Parmesan cheese.

3. Season the Chicken: Season each chicken breast on both sides with salt, pepper, onion powder, and Italian seasoning.

4. Dredge the Chicken: Coat each chicken breast in flour first, shaking off excess. Next, dip into the beaten eggs, followed by the breadcrumb mixture, ensuring a thorough coating.

5. Pan-Fry the Chicken: In a large skillet, melt butter over medium heat. Add the coated chicken breasts and cook for about 4-5 minutes on each side, or until golden brown and cooked through.

6. Prepare the Sauce: In the same skillet, lower the heat and add minced garlic. Sauté for about 1 minute before adding heavy cream. Simmer for a few minutes until it thickens slightly.

7. Combine and Bake: Add the cooked chicken back to the skillet, spooning the creamy sauce over each piece. Bake in the oven for an additional 10-15 minutes for extra flavor infusion.
