What is Chicken Cordon Bleu Casserole?
Chicken Cordon Bleu is traditionally a stuffed chicken breast filled with ham and Swiss cheese, breaded and pan-fried or baked. While delicious, the classic preparation can be time-consuming and fussy. The casserole adaptation captures all the beloved flavors in a simplified, layered format, making it perfect for busy weeknights, potlucks, or holiday gatherings.
This version maintains the elegant flair of the original dish while offering the creamy, cheesy, and savory goodness that makes casseroles such beloved staples of comfort food.
Ingredients You’ll Need
For the Casserole Base:
-
4 cups cooked chicken, cubed or shredded (rotisserie chicken works great)
-
8 oz deli-style ham, chopped
-
2 cups Swiss cheese, shredded
-
2 tablespoons butter
-
2 tablespoons all-purpose flour
-
1 ½ cups milk
-
½ cup heavy cream (or use all milk for a lighter version)
-
2 tablespoons Dijon mustard
-
1 teaspoon garlic powder
-
½ teaspoon onion powder
-
Salt and freshly cracked black pepper, to taste
For the Topping:
-
1 cup Panko breadcrumbs
-
2 tablespoons butter, melted
-
¼ cup Parmesan cheese, grated
-
Optional: 1 teaspoon dried parsley for garnish
Step-by-Step Instructions
1. Prepare the Creamy Sauce
In a medium saucepan over medium heat, melt 2 tablespoons of butter. Whisk in the flour and cook for 1–2 minutes to form a roux. Slowly whisk in the milk and cream, stirring continuously until smooth and thickened.
Add Dijon mustard, garlic powder, onion powder, salt, and pepper. Let the sauce simmer for 3–5 minutes, then stir in half of the shredded Swiss cheese. Mix until melted and creamy.
2. Assemble the Layers
Preheat your oven to 375°F (190°C). In a lightly greased 9x13-inch baking dish, layer the cubed or shredded chicken evenly across the bottom. Scatter the chopped ham over the chicken.
Pour the cheese sauce evenly over the top. Sprinkle the remaining shredded Swiss cheese over the sauce.
3. Prepare the Crunchy Topping
In a small bowl, combine Panko breadcrumbs, melted butter, and grated Parmesan. Mix until the breadcrumbs are coated and golden. Spread the topping evenly over the casserole.
4. Bake Until Golden and Bubbling
Bake uncovered for 25–30 minutes, or until the cheese is bubbly and the top is golden brown. If desired, broil for the last 2–3 minutes for an extra-crispy crust.
Let rest for 5 minutes before serving.
