• 8 ounces Swiss cheese, thinly sliced (about 12 slices).

Sauce Ingredients

• Chopped parsley (optional) – for garnish.

Equipment Needed

• 9×13-inch casserole dish
• Nonstick cooking spray
• Medium saucepan
• Whisk
• Measuring cups and spoons
• Spoon or spatula for spreading
• Oven

Preparation Method

Step 1: Preheat Oven and Prepare Casserole Dish

Preheat the oven to 350°F (175°C). Spray a 9×13-inch casserole dish with nonstick cooking spray. This ensures easy cleanup and prevents sticking.

Step 2: Layer Chicken, Ham, and Cheese

Evenly spread 5 cups shredded chicken in the prepared baking dish.

Next, layer 9 ounces sliced Black Forest ham, cut into strips, over the chicken. Make sure the ham is evenly distributed for consistent flavor in every bite.

Place 8 ounces Swiss cheese on top of the ham. Overlap slices as necessary to cover the entire surface.

Step 3: Prepare the Creamy Dijon Sauce

In a medium saucepan, melt 6 tablespoons butter over medium heat.

Whisk in:

• 1 tablespoon Dijon mustard
• 1 tablespoon lemon juice (if using)
• 1 teaspoon garlic powder
• ½ teaspoon salt
• ¼ teaspoon nutmeg (if using)
• ¼ teaspoon cayenne pepper (if using)

Sprinkle in 6 tablespoons all-purpose flour, whisking constantly to form a smooth paste (roux).

Slowly add 3 cups whole milk, about ¼ cup at a time, whisking after each addition until smooth before adding the next portion.

Allow the sauce to simmer for 4 minutes or until thickened, whisking occasionally.

Step 4: Pour Sauce Over Casserole

Pour the sauce evenly over the cheese layer, spreading carefully to cover all corners and ensure every bite will be creamy and flavorful.

Step 5: Prepare and Add Panko Topping

In a small bowl, combine 1½ cups Panko breadcrumbs with 4 tablespoons softened butter. Mix until the breadcrumbs are evenly coated with butter.

Sprinkle the breadcrumb mixture evenly over the casserole. This will create a crispy, golden crust once baked.

Step 6: Bake

Bake the casserole uncovered in the preheated oven for 30–40 minutes, or until the sauce is bubbling and the Panko topping is golden brown.

Step 7: Rest and Serve

Remove the casserole from the oven and let it sit for 5 minutes. This allows the sauce to set slightly, making it easier to serve.

Optionally, sprinkle with chopped parsley for a pop of color and fresh flavor. Serve warm.

Tips and Notes

• Ensure the Panko topping is golden brown for maximum crunch.
• Allowing the casserole to rest for 5 minutes improves texture and prevents sauce from spilling when serving.
• Use freshly shredded chicken for best texture and flavor.
• Optional spices like nutmeg and cayenne pepper add depth; adjust according to your taste preference.
• For extra flavor, consider adding sautéed mushrooms or onions to the chicken layer.
