- 1 cup milk: Creates the base for the luscious sauce, contributing smoothness without overpowering.
- 1/2 cup heavy cream: Boosts richness, making the casserole irresistibly creamy.
- 4 tablespoons butter, melted: Used both in the sauce and the topping for flavor and silkiness.
- 2 tablespoons all-purpose flour: Thickens the sauce to just the right consistency.
- 1 cup chicken broth: Adds depth and savory undertones to the creamy mixture.
- 1 tablespoon Dijon mustard: Gives a subtle tangy kick that elevates the traditional flavors.
- 1 teaspoon garlic powder: Infuses warmth and savory notes throughout.
- 1/2 teaspoon onion powder: Adds a mild, sweet pungency that balances the dish.
- 1/2 teaspoon salt: Enhances all the flavors to perfection.
- 1/2 teaspoon black pepper: Provides a gentle peppery heat for complexity.
- 1/2 cup grated Parmesan cheese: Used in the topping for a salty, nutty crunch.

How to Make Chicken Cordon Bleu Casserole Recipe
Step 1: Prepare the Base Layers
Start by preheating your oven to 375°F and lightly greasing a 9×13-inch baking dish. Spread the cubed day-old bread evenly across the bottom—this layer will soak up all the flavorful sauce later and provide a lovely textural contrast. Next, layer the shredded chicken breast over the bread, then sprinkle the chopped ham, and finally scatter the shredded Swiss cheese on top. These layers set the stage for the creamy sauce to tie everything together.
Step 2: Make the Creamy Sauce
In a saucepan over medium heat, melt 2 tablespoons of butter and whisk in the flour to create a roux; cook it for about a minute to get rid of that raw flour taste. Gradually whisk in the chicken broth, milk, and heavy cream until the sauce is smooth and creamy. Add in the Dijon mustard alongside garlic powder, onion powder, salt, and pepper. Keep cooking and stirring until the sauce thickens slightly—this rich, velvety sauce is what makes the casserole absolutely irresistible.
Step 3: Assemble and Add the Topping
Pour the prepared sauce evenly over the layered ingredients in your baking dish, allowing it to soak into the bread and coat the chicken, ham, and cheese. For the finishing touch, mix the panko breadcrumbs, grated Parmesan, and the remaining melted butter in a small bowl. Sprinkle this mixture generously over the top—this will bake up crisp and golden, adding that perfect crunchy contrast to the creamy casserole.
Step 4: Bake and Rest
Place the casserole in the oven and bake for 30 to 35 minutes, or until bubbly and the topping turns a gorgeous golden brown. Once out of the oven, allow it to rest for about 5 minutes to let the flavors meld and the casserole to set slightly before serving. Sprinkle the chopped fresh parsley over the top for a pop of color and freshness.
How to Serve Chicken Cordon Bleu Casserole Recipe
Garnishes
A sprinkle of fresh parsley is more than just pretty—it adds a subtle herbal brightness that cuts through the rich cheese and creamy sauce, refreshing your palate with every bite. For an extra special touch, a few thin slices of green onions or chives can also work beautifully.
Side Dishes
This Chicken Cordon Bleu Casserole Recipe pairs wonderfully with lightly dressed green salads, steamed vegetables like asparagus or green beans, or even a simple roasted root vegetable medley. The goal is to balance the richness with some fresh or roasted veggies for a well-rounded meal.
Creative Ways to Present
For dinner parties or family gatherings, try serving this casserole in individual ramekins for a personalized touch. You can also top each portion with a little extra cheese and breadcrumbs, then broil for a minute or two for an extra crispy cap. If you want to impress, garnish with edible flowers or fresh herb sprigs to brighten up the plate visually.
Make Ahead and Storage
Storing Leftovers
Once cooled, store any leftovers in an airtight container in the refrigerator for 3 to 4 days. The casserole’s flavors actually deepen over time, making it a delicious next-day meal.
Freezing
This casserole freezes beautifully. Prepare and assemble it as directed, but do not bake. Cover it tightly with foil or plastic wrap and freeze for up to 2 months. When ready to enjoy, bake from frozen—just add an extra 15 minutes to the baking time and ensure it’s heated through before serving.
Reheating
Reheat individual portions in the microwave or in the oven at 350°F until warmed through. If reheating a whole casserole, cover with foil to prevent over-browning, then remove the foil near the end for that crisp topping. This method keeps the dish creamy inside with the perfect crunch on top.
FAQs
Can I use a different type of cheese in this Chicken Cordon Bleu Casserole Recipe?
Absolutely! While Swiss cheese is traditional and melts beautifully, Gruyere or even a mild mozzarella can add a wonderful twist. Choose cheeses that melt well and complement the savory ham and chicken.
Is it necessary to use day-old bread?
Day-old bread is ideal because it’s a bit drier and absorbs the creamy sauce without becoming soggy. If you don’t have day-old bread, you can lightly toast fresh bread cubes before layering.
Can I make this casserole gluten-free?
Yes, simply substitute the all-purpose flour with a gluten-free flour blend and use gluten-free breadcrumbs. Make sure the chicken broth and other ingredients don’t contain hidden gluten.
What’s the best way to shred cooked chicken for this recipe?
Using two forks to pull apart warm cooked chicken works well, or if you have a stand mixer, use the paddle attachment on low speed for a quick shredding session. Rotisserie chicken is a fantastic shortcut here.
Can I prepare this recipe ahead and bake it later?
Definitely! Assemble the casserole up to the point before baking, cover tightly, and refrigerate for up to 24 hours. When ready, bake as directed—just add a few extra minutes if it’s coming straight from the fridge.
