Ingredients

For the Casserole:

• 4 cups cooked chicken, shredded or cubed
• 6 slices of deli-style ham, chopped
• 6 slices of Swiss cheese (or 1 cup shredded Swiss cheese)

For the Sauce:

• 3 tablespoons unsalted butter
• 3 tablespoons all-purpose flour
• 2 cups milk (whole milk or 2%)
• 1/2 teaspoon garlic powder
• 1/2 teaspoon onion powder
• 1/2 teaspoon Dijon mustard
• 1/4 teaspoon paprika
• Salt and black pepper, to taste
• 1/2 cup grated Parmesan cheese

For the Topping:

• 1 cup panko breadcrumbs
• 2 tablespoons unsalted butter, melted
• 1/4 cup grated Parmesan cheese
• 1 teaspoon dried parsley

Step-by-Step Instructions

Step 1: Preheat the Oven

1. Preheat your oven to 375°F (190°C). Grease a 9×13-inch baking dish and set it aside.

Step 2: Prepare the Chicken Layer

1. Spread the cooked chicken evenly across the bottom of the prepared baking dish.

Step 3: Add the Ham and Cheese

1. Scatter the chopped ham evenly over the chicken layer.
2. Lay the slices of Swiss cheese over the ham, or sprinkle shredded Swiss cheese evenly across the top.

Step 4: Make the Creamy Sauce

1. In a medium saucepan, melt the butter over medium heat. Once melted, whisk in the flour to form a smooth paste (roux). Cook for 1–2 minutes, stirring constantly.
2. Gradually whisk in the milk, ensuring no lumps form. Add the garlic powder, onion powder, Dijon mustard, paprika, salt, and pepper.
3. Continue to cook, whisking frequently, until the sauce thickens and coats the back of a spoon (about 3–5 minutes).
4. Stir in the grated Parmesan cheese and mix until melted and smooth.

Step 5: Assemble the Casserole

1. Pour the creamy sauce evenly over the chicken, ham, and cheese layers in the baking dish.

Step 6: Prepare the Breadcrumb Topping

1. In a small bowl, mix the panko breadcrumbs, melted butter, grated Parmesan, and dried parsley. Toss until the breadcrumbs are evenly coated.
2. Sprinkle the breadcrumb mixture evenly over the casserole.

Step 7: Bake

1. Bake the casserole in the preheated oven for 30–35 minutes, or until the topping is golden brown and the sauce is bubbling around the edges.

Step 8: Cool and Serve

1. Remove the casserole from the oven and let it rest for 5–10 minutes before serving. This allows the layers to set and makes it easier to portion.

Ingredient Background

Chicken

Cooked and shredded or cubed chicken serves as the hearty base of this casserole. Rotisserie chicken is a convenient option, but leftover grilled or baked chicken works just as well.

Ham

Thinly sliced deli ham adds a savory, smoky flavor that complements the creamy sauce and Swiss cheese.

Swiss Cheese

Swiss cheese melts beautifully and provides the mild, nutty flavor characteristic of traditional Chicken Cordon Bleu. Gruyère or provolone can be used as alternatives.

Panko Breadcrumbs

Panko breadcrumbs create a light, crispy topping that contrasts perfectly with the creamy casserole layers.

Dijon Mustard

A small amount of Dijon mustard adds depth and a subtle tanginess to the creamy sauce.

Technique Tips

Layer Evenly: Distribute the chicken, ham, and cheese evenly for balanced flavor in every bite.

Thicken the Sauce: Whisk the sauce continuously as it cooks to prevent lumps and ensure a smooth consistency.

Golden Topping: Keep an eye on the casserole in the last few minutes of baking to prevent the breadcrumbs from over-browning.

Shredded Cheese: If using shredded Swiss cheese, grate it yourself for better melting. Pre-shredded cheeses often contain anti-caking agents that can affect texture.

Alternative Presentation Ideas

Individual Servings: Assemble the casserole in small ramekins for single-serving portions, perfect for dinner parties or meal prep.

Roll-Up Style: Roll slices of ham and cheese around small chicken pieces, then place them in the dish and cover with sauce and breadcrumbs for a fun variation.

Vegetable Layer: Add a layer of steamed broccoli or spinach between the chicken and ham for extra nutrients and color.

Additional Tips for Success

Make-Ahead Option: Assemble the casserole up to 24 hours in advance, cover it tightly, and refrigerate. Add the breadcrumb topping just before baking.

Use Leftovers: This recipe is a great way to use leftover chicken or ham from a holiday meal.

Reheat Properly: To reheat, cover the casserole with foil and bake at 350°F (175°C) for 15–20 minutes. Uncover for the last few minutes to crisp the topping.

Recipe Variations

Low-Carb Version: Replace the panko breadcrumbs with crushed pork rinds or almond flour for a keto-friendly version.

Gluten-Free Option: Use gluten-free breadcrumbs and substitute the flour in the sauce with cornstarch or gluten-free flour.

Cheesy Upgrade: Add a layer of shredded mozzarella or sharp cheddar for extra cheesiness.

Spicy Casserole: Add a pinch of cayenne pepper or red pepper flakes to the sauce for a subtle kick.

Freezing and Storing

Refrigeration: Store leftover casserole in an airtight container in the refrigerator for up to 3 days.

Freezing: To freeze, assemble the casserole but don’t add the breadcrumb topping. Wrap the dish tightly in plastic wrap and aluminum foil, and freeze for up to 2 months. Thaw overnight in the refrigerator, add the topping, and bake as directed.

Healthier Twist Ideas

Lean Protein: Use skinless chicken breasts or turkey for a leaner option.

Low-Fat Dairy: Substitute regular milk with low-fat milk and use reduced-fat cheese for a lighter version.

Add Veggies: Incorporate vegetables like zucchini, mushrooms, or asparagus into the layers for added fiber and nutrients.

Whole Wheat Breadcrumbs: Use whole wheat panko for a healthier topping with more fiber.

Serving Suggestions for Events

Family Dinner: For a comforting family meal, serve this Chicken Cordon Bleu Casserole alongside roasted vegetables such as carrots, broccoli, or Brussels sprouts. Add a simple green salad with a light vinaigrette to balance the rich flavors of the casserole. A warm loaf of crusty bread or dinner rolls on the side is perfect for soaking up the creamy sauce, making it a complete and satisfying dinner that everyone will love.

Potluck Favorite: This casserole is a standout dish for potlucks or gatherings, as it’s easy to prepare in advance and travels well. Transport it in a disposable aluminum baking dish for convenience and less cleanup. Garnish with fresh parsley or thyme sprigs right before serving to add a pop of color and an elegant touch. Pair it with other potluck classics like pasta salad or fruit platters for a well-rounded spread.

Holiday Spread: This casserole shines on a holiday dinner table, served alongside traditional sides such as mashed potatoes, green beans, cranberry sauce, and stuffing. Its creamy, cheesy layers complement festive dishes perfectly, adding a hearty and comforting element to the meal. For an extra festive touch, sprinkle the top with a mix of chopped parsley and dried cranberries before serving.
