Ingredients

2 chicken breasts cut in half
8 slices sliced ham
8 slices Sliced Swiss cheese
2 tablespoons Dijon mustard
2 tablespoons Mayonnaise
3/4 teaspoon salt
1/2 teaspoon pepper
1/2 teaspoon paprika
1/2 teaspoon garlic powder
Fresh Parsley optional

Topping

2 cups panko bread crumbs
6 tablespoons butter melted

Sauce

4 tablespoons flour
4 tablespoons butter
2-3 tablespoons mustard use more for a bigger kick
2 cups milk or 1 1/2 c milk and 1/2 c chicken stock
salt & pepper to taste
1/4 teaspoon cayenne pepper optional

Instructions

Prep for the Chicken Cordon Bleu Casserole

Preheat the oven to 350°F degrees and spray a 9 x 13 baking dish with nonstick cooking spray.
Spread the panko breadcrumbs on a baking sheet and place in the oven for 10-12 minutes stirring occasionally till golden. Set aside to cool.
While the breadcrumbs are in the oven make the sauce.

How to Make Dijon Mustard Sauce

In a sauce pot over medium heat add the butter and cook until melted.
Once the butter is fully melted, add the flour and whisk quickly. The mixture will be thick and bubbly.
Once it thins out, you can stop whisking. Let cook for 3 minutes stirring occasionally. Add the mustard, milk, salt, pepper, and cayenne and mix well. Let cook for 2-3 minutes. Set aside and let cool.

Assemble the Casserole

Slice each individual chicken breast in half length wise so you have 2 thin pieces of chicken from each chicken breast.
Place the chicken breast halves in the casserole dish in a single layer
Mix mustard, mayo, salt, pepper, paprika, and garlic, divide evenly (1 tablespoon per chicken), and spread on top of the chicken.
Layer two slices of ham over each piece of chicken, and pour 1 cup of sauce over the ham and chicken.
Then add 2 slices of Swiss cheese on top of each piece of chicken.
In a medium bowl add the 6 tablespoons of butter and melt in the microwave. (30 - 45 seconds in the microwave)
Add the panko breadcrumbs to the melted butter and mix well. Spread the panko bread crumbs on top of the casserole.
Bake for 25-30 minutes or until the chicken reaches an internal temperature of 165 degrees.
Reheat remaining sauce to serve with casserole; optional. Thin with water or chicken stock according to preference. I like to add another cup or two of water to make it a lot thinner and easier to pour as a sauce.
