2 large thin boneless, skinless chicken breasts (about 1½ pounds)
¾ tsp salt, divided
¾ tsp freshly ground black pepper, divided
4 thin slices black forest ham
1 cup (4 oz) shredded Gruyère, Emmenthal, or Swiss cheese
½ cup all-purpose flour
2 large eggs
1 tbsp Dijon mustard
1 cup Dynasty Japanese Style Panko Breadcrumbs
3 tbsp unsalted butter, melted and slightly cooled
¼ cup grated Parmigiano Reggiano cheese
Sauce:
3 tbsp unsalted butter
3 tbsp minced shallots
2 tbsp all-purpose flour
1½ cups chicken stock
⅓ cup heavy cream
¼ tsp salt
⅛ tsp freshly ground black pepper
1 tsp Dijon mustard
2 tbsp grated Parmigiano Reggiano cheese
1 tsp fresh chopped thyme
Directions
Prepare the Chicken for Filling: Lay each chicken breast vertically, smooth side down, on a 12x16-inch piece of plastic wrap that is positioned horizontally. Evenly season the rough sides (facing up) with ½ teaspoon salt and ½ teaspoon pepper.
Place ¼ cup shredded Gruyère in the center of each ham slice. Fold the ham over the cheese, starting with the sides and then the top and bottom. This encases the cheese within the ham, forming neat packets. Place the packets seam-side down to keep them closed.
Assemble and Roll: Place these ham and cheese packets atop the seasoned chicken breasts, towards the end closest to you. Begin rolling the chicken away from you, enclosing the ham and cheese packet tightly. As you roll, tuck in the chicken's sides. Once rolled, wrap the chicken tightly in the plastic wrap, squeezing gently to seal and twisting both ends to form a log-like shape. Repeat with the remaining pieces. Refrigerate the chicken for at least 30 minutes or up to 1 day.
Preheat the oven to 375°F and set an oven rack in the middle position. Line a rimmed baking sheet with aluminum foil and spray with nonstick cooking spray.
Bread the Chicken: Set out three large shallow bowls. Place the flour in the first bowl. Beat the eggs and mustard in the second bowl. In the third bowl, mix the Dynasty Japanese Style Panko Breadcrumbs, butter, Parmigiano Reggiano cheese, and the remaining ¼ teaspoon each of salt and pepper. Set up a breading station in this order: flour, egg/mustard mixture, panko mixture.
Remove the plastic wrap from the chicken cordon bleu rolls. Gently dredge each roll in the flour, coating evenly all around; dip in the egg/mustard mixture; then dredge in the panko mixture, turning and patting to adhere. Place the breaded chicken on the prepared baking sheet. Bake for about 25 minutes, until lightly golden and cooked through. Allow the chicken to rest on the baking sheet for 5 minutes before serving with the sauce. If you wish to slice it into pinwheels, use a serrated knife with a gentle sawing motion, as the breading can be delicate.
While the chicken bakes, make the sauce. In a medium skillet over medium heat, melt the butter. Add the shallots and cook, stirring occasionally, until softened, 2 to 3 minutes. Stir in the flour and cook, stirring constantly, for about 1 minute. Add the chicken stock, stirring to combine, and then bring to a boil. Add the heavy cream, salt, pepper, mustard, and Parmigiano Reggiano and simmer until thickened, about 2 minutes. Add the thyme, then taste and adjust seasoning if necessary.
