Creating Chicken Fillet in Spicy, Creamy Garlic-Parmesan Sauce with Fries is straightforward and enjoyable by following these steps:

1. Prepare the Fries: If using frozen fries, follow package instructions for cooking. For homemade fries, slice potatoes, season with salt, and bake or fry until golden and crispy.

2. Season the Chicken: Pat the chicken fillets dry with paper towels. Season both sides with salt, pepper, and Italian seasoning.

3. Sear the Chicken: Heat olive oil and butter in a large skillet over medium-high heat. Once hot, add the chicken fillets. Cook for about 5-7 minutes on each side or until fully cooked and golden brown. Remove from the skillet and set aside.

4. Make the Sauce: In the same skillet, reduce the heat to medium. Add minced garlic and red pepper flakes. Sauté for about 1-2 minutes, until fragrant.

5. Add Cream and Cheese: Pour in the heavy cream and bring it to a boil. Lower the heat and add grated Parmesan cheese, stirring until melted and fully incorporated.

6. Combine and Season: Return the chicken fillets to the skillet, coating them in the creamy sauce. Simmer for an additional 2-3 minutes to meld the flavors together.

7. Adjust Seasoning: Taste and adjust the seasoning, adding more salt, pepper, or red pepper flakes as needed.

8. Serve: Plate the chicken fillets with generous amounts of the spicy garlic-Parmesan sauce poured over the top. Add a side of crispy fries to the plate.

9. Garnish: Sprinkle freshly chopped parsley over the dish for an extra splash of color.

By following these steps, you will create an amazing Chicken Fillet in Spicy, Creamy Garlic-Parmesan Sauce with Fries that is sure to impress everyone at your table.
