Step-by-Step Instructions

Searing the Oven:

Preheat your oven to 350 degrees Fahrenheit. Lightly spray a 9 by 13-inch casserole dish with nonstick spray to ensure easy cleanup and prevent sticking.

Layering the Base:

Spread five cups of shredded chicken evenly across the bottom of the casserole dish. This forms a hearty foundation for the flavors to build on.

Adding the Ham:

Next, layer nine ounces of deli-style black forest ham, cut into strips, over the shredded chicken. The smoky ham adds savory interest in every bite.

Cheese Layer:

Place eight ounces of Swiss cheese slices over the ham. Overlap the slices slightly so they fit snugly into the casserole and melt evenly.

Making the Sauce:

In a medium saucepan over medium heat, melt six tablespoons of unsalted butter. Once melted, whisk in one tablespoon of Dijon mustard, one tablespoon of lemon juice if you are using it, one teaspoon of garlic powder, half a teaspoon of salt, and optional quarter teaspoons of nutmeg and cayenne pepper. Whisk continuously to combine all the flavors.

Thickening the Sauce:

Sprinkle six tablespoons of all-purpose flour over the butter and spice mixture. Keep whisking steadily to form a smooth paste without lumps. This step is crucial for a creamy, lump-free sauce.

Adding Milk:

Slowly pour in three cups of whole milk, adding about a quarter cup at a time. Whisk constantly to keep the mixture silky and smooth before adding the next portion of milk.

Simmering:

Allow the sauce to simmer gently for about four minutes while whisking occasionally. It will thicken beautifully and develop a rich flavor.

Pouring the Sauce:

Pour the thickened sauce evenly over the cheese layer, making sure to reach into all corners of the casserole so every bite is coated with the creamy goodness.

Preparing the Topping:

In a small bowl, combine one and a half cups of Panko breadcrumbs with four tablespoons of softened unsalted butter. Mix well until the breadcrumbs are evenly coated. Then spread this mixture evenly over the top of the casserole for a crispy, golden crust.

Baking:

Place the casserole uncovered in the preheated oven. Bake for 30 to 40 minutes, or until the sauce is bubbling and the Panko topping has turned a lovely golden brown.

Resting and Serving:

Remove the casserole from the oven and let it rest for five minutes. This resting time allows the sauce to set slightly, making it easier to serve. Optionally, sprinkle chopped parsley on top for a fresh, vibrant finish.

My favorite ingredient in this dish has to be the black forest ham. Its smoky sweetness pairs so perfectly with the tangy mustard sauce. I remember one Thanksgiving when we made this casserole as a comforting change from the usual turkey; it quickly became the new tradition.

Storage Tips

Place leftovers in an airtight container to maintain freshness and keep the sauce from drying out. For best results, reheat individual servings in the microwave or warm the entire casserole in the oven at a low temperature until heated through. If you plan to freeze, wrap tightly with foil and plastic wrap. Thaw overnight in the fridge before reheating.

Ingredient Substitutions

For a gluten-free version, replace the all-purpose flour with a gluten-free flour blend and choose gluten-free Panko or crushed gluten-free crackers for the topping. Swiss cheese can be swapped for Gruyère or Emmental for a different but equally delicious flavor profile. Add a layer of fresh spinach or cooked broccoli between the ham and cheese for extra nutrition and color.

Serving Suggestions

Pair this casserole with lightly steamed green beans or a crisp side salad with vinaigrette to balance the richness. A glass of crisp white wine or sparkling water with lemon complements the creamy sauce beautifully. A simple garlic bread or dinner rolls work great to soak up any extra sauce on the plate.
