Creating Longhorn Steakhouse Parmesan Chicken is simple if you follow these step-by-step instructions:

1. Prepare the Chicken: Begin by seasoning the chicken breasts with salt, pepper, garlic powder, and Italian seasoning on both sides.
2. Cook the Chicken: Heat olive oil in a large skillet over medium heat. Add the seasoned chicken breasts and cook for about 5-7 minutes on each side until they are golden brown and cooked through. Internal temperature should reach at least 165°F (75°C).
3. Prepare the Sauce: Reduce heat to low. In the same skillet, pour in the cooking cream and stir, incorporating any browned bits from the chicken for extra flavor.
4. Add Cheese: Gradually whisk in the grated Parmesan cheese until the sauce is smooth and creamy. Allow it to simmer for a few minutes until it thickens.
5. Combine: Once the sauce has reached your desired consistency, return the cooked chicken to the skillet, coating each piece with the creamy sauce.
6. Serve: After simmering for another 2-3 minutes, remove from heat. Garnish with freshly chopped parsley.
7. Plate: Serve the chicken immediately, spooning additional sauce over the top.

With these straightforward steps, you’re sure to create a fantastic dish that mimics the flavors of the beloved original.
