Creating Chicken Cordon Bleu with Swiss Cheese Sauce can be simple if you follow these steps:

1. Preheat Your Oven: Preheat your oven to 375°F (190°C).
2. Prepare Chicken: Place chicken breasts between two sheets of plastic wrap. Gently pound them to an even thickness of about 1/2 inch using a meat mallet or rolling pin.
3. Assemble Chicken: Lay a slice of ham and a slice of Swiss cheese on each chicken breast. Roll the chicken tightly and secure with toothpicks.
4. Prepare Breading Station: Set up three shallow bowls—one with flour, one with beaten eggs, and one with breadcrumbs mixed with garlic powder, paprika, salt, and pepper.
5. Bread the Chicken: Dredge each chicken roll in flour, then dip it in the egg, and finally coat it with breadcrumbs. Ensure each piece is well-coated.
6. Heat Oil: In a large oven-safe skillet, heat olive oil over medium heat. Once hot, add the chicken rolls and sear them for about 3-4 minutes on each side until golden brown.
7. Bake: Transfer the skillet to the preheated oven and bake for about 20-25 minutes, or until the chicken is cooked through and reaches an internal temperature of 165°F (75°C).
8. Prepare Swiss Cheese Sauce: While the chicken bakes, prepare the sauce. In a saucepan, heat the heavy cream over medium heat. Stir in the shredded Swiss cheese and Dijon mustard until melted and smooth.
9. Remove Toothpicks: Once the chicken is done, remove it from the oven and let it rest for 5-10 minutes. Carefully remove the toothpicks.
10. Serve: Slice the Chicken Cordon Bleu and drizzle with the Swiss cheese sauce. Garnish with fresh parsley for added color and flavor.
