  • 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



  • 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


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.
