For the Casserole:

  • 4 cups cooked and shredded chicken breast
  • 8 slices ham, thinly sliced
  • 8 slices Swiss cheese
  • 1 cup shredded mozzarella cheese

For the Dijon Cream Sauce:

  • 1/4 cup unsalted butter
  • 1/4 cup all-purpose flour (or almond flour for low-carb)
  • 2 cups whole milk (or unsweetened almond milk for low-carb)
  • 2 tablespoons Dijon mustard
  • 1 teaspoon garlic powder
  • Salt and black pepper to taste


  1. Preheat the Oven: Preheat your oven to 375°F (190°C) and grease a baking dish.
  2. Layer the Casserole:
  • Spread the shredded chicken evenly across the bottom of the baking dish.
  • Layer the thinly sliced ham over the chicken.
  • Arrange the Swiss cheese slices over the ham.
  1. Prepare the Dijon Cream Sauce:
  • In a saucepan, melt the butter over medium heat.
  • Add the flour and whisk continuously to create a roux.
  • Gradually pour in the milk, whisking constantly to avoid lumps.
  • Stir in the Dijon mustard, garlic powder, salt, and black pepper.
  • Allow the sauce to thicken to a creamy consistency.
  1. Pour Over Layers:
  • Pour the Dijon cream sauce over the layers in the baking dish, ensuring an even distribution.
  1. Top with Mozzarella:
  • Sprinkle the shredded mozzarella cheese over the top layer.
  1. Bake:
  • Bake the casserole in the preheated oven for 25-30 minutes or until the top is golden brown and the casserole is bubbly.
  1. Broil (Optional):
  • If desired, broil the casserole for an additional 2-3 minutes to achieve a crispy top layer.
  1. Rest and Serve:
  • Allow the Chicken Cordon Bleu Casserole to rest for a few minutes before slicing and serving.

Cook’s Notes:

  • You can use store-bought rotisserie chicken as a time-saving shortcut.
  • Experiment with different cheese blends or add herbs for extra flavor.
  • For a keto version, use almond flour in the Dijon cream sauce and unsweetened almond milk to reduce the carb content.
  • For a low-carb version, opt for almond flour in the sauce and minimize higher-carb vegetables if adding any.
