Ingredients You’ll Need

The beauty of Chicken Cordon Bleu Casserole is how a handful of familiar ingredients magically combine to create a dish that’s cozy, flavorful, and crave-worthy. Each ingredient has a role—whether it’s lending richness, creaminess, or that essential buttery crunch on top.

• Egg noodles: Wide, tender noodles serve as the hearty base and catch all the creamy sauce.
• Seasoned breadcrumbs: These add a golden, crisp finish that’s classic for cordon bleu.
• Butter (melted): Blended with breadcrumbs, it helps them brown beautifully and adds richness.
• Cream of chicken soup: This shortcut ingredient makes the sauce velvety and flavorful with minimal effort.
• Sour cream: Adds a tangy creaminess to the casserole’s sauce.
• Milk: Thins the sauce just enough so it coats every bite.
• Dijon mustard: The secret weapon—it wakes up all the flavors with a pop of subtle sharpness.
• Shredded Swiss cheese: Essential for its nutty, melty goodness that makes cordon bleu, well, cordon bleu!
• Shredded mozzarella cheese: Melts beautifully and adds a stretchy, mild cheesy bite.
• Shredded cooked chicken: Use leftover chicken or rotisserie for convenience, or quickly poach your own.
• Sliced deli ham: Salty and savory, it adds that unmistakable cordon bleu touch—cut in strips so it’s easy to eat in every forkful.

How to Make Chicken Cordon Bleu Casserole

Step 1: Preheat the Oven

Set your oven to 400℉ so it’s ready to create that bubbly, golden finish we all look forward to with Chicken Cordon Bleu Casserole. This temperature ensures everything melds together and that the topping gets irresistibly crunchy.

Step 2: Boil the Egg Noodles

Bring a big pot of salted water to a rolling boil, then cook your egg noodles until they’re just al dente—tender, but not mushy. Drain them well so they don’t water down your creamy sauce later on.

Step 3: Mix Breadcrumb Topping

While your noodles cook, quickly combine the seasoned breadcrumbs and melted butter in a small bowl. This will be your crowning crunchy layer, so don’t skip it! Set aside until assembly.

Step 4: Make the Creamy Sauce Base

In your 9″x13″ baking dish (no extra bowl needed!), whisk together the condensed cream of chicken soup, sour cream, milk, and that magical spoonful of Dijon mustard. Stir in both the Swiss and mozzarella cheeses for a luscious sauce you’ll want to dive into with a spoon.

Step 5: Assemble the Casserole

Add your cooked egg noodles, shredded chicken, and strips of ham directly to the creamy sauce. Give everything a gentle stir so every piece gets coated with flavor. Sprinkle the buttery breadcrumbs evenly on top—this is what creates that Cordon Bleu signature crunch.

Step 6: Bake to Golden Perfection

Pop the dish in your preheated oven and bake for 20 to 25 minutes. The casserole should be heated through and the breadcrumb topping should be gorgeously crisp and golden. Once it’s out, let it rest for 5 minutes to set up and make serving easier.

How to Serve Chicken Cordon Bleu Casserole

Garnishes

A sprinkling of fresh chopped parsley or chives right before serving adds a burst of color and a slight freshness that pairs beautifully with the creamy, cheesy flavors. If you’re feeling fancy, a dusting of cracked black pepper really sets it off.

Side Dishes

Pair your Chicken Cordon Bleu Casserole with something bright and crisp to balance the richness—a green salad with a tangy vinaigrette is always a hit. Steamed green beans or roasted asparagus make lovely, colorful sides that fill out the meal without competing for attention.

Creative Ways to Present

For a fun twist, try baking the casserole in individual ramekins for a dinner party—everyone gets their own golden-crusted portion! Or, scoop hearty servings onto toasted, buttery baguette slices for an elevated snack at your next casual gathering. Kids especially love it when it’s cut into squares for easy, handheld bites.

Make Ahead and Storage

Storing Leftovers

Let any leftover Chicken Cordon Bleu Casserole cool completely, then cover tightly and refrigerate for up to four days. The flavors actually deepen overnight, making for some irresistible next-day lunches!

Freezing

You can easily freeze this casserole either before baking or after. For best results, wrap tightly in a layer of plastic and foil, and freeze for up to three months. If freezing unbaked, wait to add the crumb topping until just before you’re ready to bake.

Reheating

To reheat, cover with foil and warm in a 350℉ oven until hot throughout, about 20 minutes. For that just-baked crunch, uncover for the last 5 minutes. Individual portions also heat up well in the microwave; just add a splash of milk if needed to loosen the sauce.

FAQs

Can I use rotisserie chicken for Chicken Cordon Bleu Casserole?

Absolutely! Rotisserie chicken is a wonderful shortcut for this dish and keeps everything moist and flavorful. Just shred or chop it up and you’re ready to go.

What can I use instead of Swiss cheese?

Gruyère is a classic swap if you have it on hand, or you can use any mild, melty cheese like provolone. Just be sure to keep some of the signature nuttiness that makes Chicken Cordon Bleu Casserole special.

Can I prepare Chicken Cordon Bleu Casserole in advance?

Definitely! You can assemble the casserole (up to the breadcrumb topping) and store it covered in the refrigerator for a day in advance. Add the topping right before baking for the best texture.

Is there a way to lighten up this recipe?

For a lighter take, use reduced-fat dairy products and lean ham, or substitute plain Greek yogurt for sour cream. You could also swap half of the noodles for cooked cauliflower for a veggie boost!

How do I keep the noodles from getting mushy?

Make sure to cook the noodles just until al dente and drain them well. They’ll finish soaking up flavor from the sauce as the casserole bakes without becoming too soft.
