Follow these easy steps to create your own crispy and creamy Chicken Cordon Bleu with Dijon sauce:

1. Preheat the Oven: If baking, set your oven to 375°F (190°C). Prepare a baking dish by greasing it lightly or lining it with parchment paper.

2. Prepare Chicken: Place each chicken breast between two pieces of plastic wrap. Using a meat mallet or rolling pin, gently pound them to an even thickness of about ½ inch.

3. Season: Season both sides of the chicken breasts with salt and pepper for added flavor.

4. Add Filling: Lay two slices of ham and two slices of Swiss cheese on top of each chicken breast. Fold the chicken over to encase the filling. Secure with toothpicks if necessary.

5. Set Up Breading Station: Place the flour, beaten eggs, and breadcrumbs in three separate shallow dishes.

6. Coat Chicken: Dredge each chicken roll in flour, shaking off excess, then dip into the beaten eggs, and finally coat with breadcrumbs. Ensure an even coating for maximum crispiness.

7. Heat Oil: In a large skillet, heat olive oil or butter over medium-high heat until hot.

8. Cook Chicken: Carefully place the chicken rolls in the skillet and sauté until golden brown on both sides (about 3-4 minutes per side). Transfer to the prepared baking dish if baking.

9. Finish in Oven: Bake in the preheated oven for an additional 15-20 minutes or until the chicken is cooked through (internal temperature of 165°F or 75°C).

10. Prepare Dijon Sauce: In a small saucepan over medium heat, combine heavy cream and Dijon mustard. Stir until heated through and well combined, about 3-4 minutes. Add salt and pepper to taste.

11. Rest the Chicken: Once cooked, remove the chicken from the oven and allow them to rest for about 5-10 minutes before removing toothpicks.

12. Slice and Serve: Using a sharp knife, slice the chicken rolls in half to reveal the cheesy, ham-stuffed center.
