Ingredients
  

For the Casserole
  • 2 lbs boneless, skinless chicken breasts cut into 1-inch cubes
  • 1 tsp garlic powder
  • 1/2 lb sliced deli ham such as Black Forest
  • 8 slices Swiss cheese
For the Creamy Dijon Sauce
  • 4 tbsp unsalted butter
  • 1/4 cup all-purpose flour
  • 2 cups milk
  • 4 oz cream cheese softened
  • 2 tbsp Dijon mustard
  • 1/4 tsp nutmeg
  • Salt and black pepper to taste
For the Topping
  • 1 cup Panko breadcrumbs
  • 4 tbsp butter melted
  • 1/4 cup grated Parmesan cheese

Equipment

  • 1 9x13 inch Baking Dish
  • 1 Saucepan
  • 2 Mixing Bowls

Method
 

  1. Preheat oven to 375°F (190°C). Lightly grease a 9x13 inch baking dish.
  2. Season the chicken cubes with salt, pepper, and garlic powder. Arrange them in a single layer in the prepared baking dish.
  3. Layer the sliced ham over the chicken.
  4. To make the sauce, melt 4 tbsp of butter in a saucepan over medium heat. Whisk in the flour and cook for 1 minute. Gradually whisk in the milk until smooth. Cook until the sauce thickens, about 5-7 minutes. Remove from heat and stir in the cream cheese, Dijon mustard, nutmeg, salt, and pepper until smooth.
  5. Pour the creamy sauce evenly over the chicken and ham. Top with slices of Swiss cheese.
  6. In a small bowl, combine the panko breadcrumbs, 4 tbsp of melted butter, and Parmesan cheese. Sprinkle this mixture evenly over the casserole.
  7. Bake for 25-30 minutes, or until the sauce is bubbly and the topping is golden brown. Let it rest for 5-10 minutes before serving.

Notes

For best results, use freshly shredded Swiss cheese for a smoother melt.
You can assemble the casserole up to 24 hours in advance without the topping. Add the topping just before baking.
