There’s comfort food, and then there’s Chicken Cordon Bleu Casserole—the kind of dish that wraps you in warmth with every single bite. This recipe takes everything we love about the elegant French classic—tender chicken, smoky ham, melted Swiss cheese, and that irresistible creamy sauce—and transforms it into an easy, family-friendly casserole that’s perfect for busy weeknights yet impressive enough for Sunday dinner. Topped with buttery, golden breadcrumbs that shatter against your fork, this dish delivers restaurant-quality flavor with a fraction of the effort.
I’ll never forget the first time I made this chicken cordon bleu casserole. It was the week after Thanksgiving, and I was drowning in leftover ham with no idea what to do with it all. My kids were getting tired of ham sandwiches, and I desperately needed inspiration. That’s when I remembered my grandmother’s traditional chicken cordon bleu—that fancy stuffed chicken dish she’d make for special occasions. I wondered: what if I could capture those same flavors without all the pounding, rolling, and frying? The result exceeded my wildest expectations. The creamy Swiss cheese sauce enveloped tender chunks of chicken and ham, while the crispy breadcrumb topping provided the perfect textural contrast. My teenagers—notoriously picky eaters—went back for thirds. This creamy chicken cordon bleu casserole has been in regular rotation ever since.
A Visual Delight: The Ultimate Chicken Cordon Bleu Casserole
The sight of this casserole fresh from the oven is enough to make anyone’s mouth water. Imagine a spoon lifting a generous portion from a bubbling baking dish, trailing long, impossibly stretchy strings of melted cheese that simply refuse to let go. The filling is a gorgeous, creamy amalgamation of tender pasta, chunks of seasoned chicken, and pink pieces of ham, all suspended in a luscious, ivory-colored cheese sauce that clings to every element. On top, golden-brown breadcrumbs have formed a perfectly crispy crust, some edges darker and more caramelized than others, creating an irresistible texture. Flecks of fresh green parsley dot the surface, adding color and freshness to the rich dish. The sauce is clearly thick and creamy—not watery—pooling slightly around the edges of the serving spoon. It’s the kind of image that stops you mid-scroll and sends you straight to the kitchen.
Why This Chicken Cordon Bleu Casserole Recipe Is a Winner
Traditional chicken cordon bleu is delicious but labor-intensive. You have to pound chicken breasts thin, layer them with ham and cheese, roll them up tightly, bread them, and then carefully pan-fry or bake them without having them fall apart. This casserole captures every bit of that flavor—the Swiss cheese, the Dijon mustard, the smoky ham, the tender chicken—in a format that’s exponentially easier to prepare.
The homemade cheese sauce is the heart of this dish. Made with butter, flour, milk, and plenty of Swiss cheese, it’s velvety smooth and deeply flavorful. The Dijon mustard adds that quintessential cordon bleu tang, while a touch of nutmeg—the classic French seasoning—adds warmth and complexity. The pasta absorbs just enough sauce to become tender and flavorful while still holding its shape, and the breadcrumb topping bakes to golden, buttery perfection.
Complete Ingredients for Chicken Cordon Bleu Casserole
For the Casserole Base:
- 12 oz (340g) pasta (penne, rotini, or egg noodles)
- 2 cups cooked chicken, cubed or shredded (rotisserie chicken works great)
- 1.5 cups diced ham
- 2 cups shredded Swiss cheese, divided
For the Creamy Swiss Cheese Sauce:
- 4 tablespoons butter
- ¼ cup all-purpose flour
- 2.5 cups whole milk
- ½ cup chicken broth
- 2 tablespoons Dijon mustard
- ½ teaspoon garlic powder
- ¼ teaspoon smoked paprika
- ⅛ teaspoon nutmeg
- Salt and white pepper to taste
For the Crispy Breadcrumb Topping:
- 1 cup panko breadcrumbs
- 3 tablespoons melted butter
- 2 tablespoons grated Parmesan cheese
- Fresh parsley for garnish
Step-by-Step Instructions for Chicken Cordon Bleu Casserole
- Preheat and Prepare: Preheat your oven to 350°F (175°C). Spray a 9×13-inch baking dish with cooking spray and set aside. This size is perfect for feeding a family of 6 with room for seconds.
- Cook the Pasta: Bring a large pot of salted water to a boil. Cook the pasta according to package directions, but pull it out 1 to 2 minutes before it reaches al dente—it will continue cooking in the oven. Drain well and set aside.
- Make the Cheese Sauce: In a large saucepan, melt the butter over medium heat. Whisk in the flour and cook for 1 to 2 minutes, stirring constantly—this cooks out the raw flour taste. Slowly pour in the milk and chicken broth, whisking continuously to prevent lumps. Continue cooking and whisking until the sauce thickens enough to coat the back of a spoon, about 5 to 7 minutes.
- Season the Sauce: Remove the saucepan from heat. Whisk in the Dijon mustard, garlic powder, smoked paprika, and nutmeg. Add 1 cup of the shredded Swiss cheese and stir until completely melted and smooth. Season with salt and white pepper to taste. The sauce should be rich, creamy, and deeply flavorful.
- Combine the Components: In a large bowl, combine the cooked pasta, cubed chicken, and diced ham. Pour the warm cheese sauce over the mixture and stir gently until everything is evenly coated. The sauce should cling to every piece of pasta, chicken, and ham.
- Assemble the Casserole: Transfer the mixture to your prepared baking dish, spreading it evenly. Sprinkle the remaining 1 cup of Swiss cheese over the top in an even layer.
- Prepare the Topping: In a small bowl, combine the panko breadcrumbs, melted butter, and Parmesan cheese. Toss until the breadcrumbs are evenly coated with butter. Sprinkle this mixture evenly over the cheese-topped casserole.
- Bake to Perfection: Bake uncovered for 25 to 30 minutes, until the casserole is bubbling around the edges and the breadcrumb topping is deeply golden brown. For extra crispiness, broil for 1 to 2 minutes at the end, watching carefully to prevent burning.
- Rest and Serve: Let the casserole rest for 5 to 10 minutes before serving—this allows the sauce to thicken slightly and makes for easier portioning. Garnish with fresh chopped parsley and serve hot.
Essential Notes for the Best Chicken Cordon Bleu Casserole
- Use rotisserie chicken for the easiest preparation—it’s already seasoned and perfectly tender.
- Don’t skip the Dijon mustard—it’s essential for authentic cordon bleu flavor.
- For a thicker sauce, reduce the chicken broth or add an extra tablespoon of flour.
- Undercook your pasta slightly—it absorbs liquid during baking and you don’t want mushy noodles.
- Use white pepper instead of black for a more elegant appearance—no dark specks in your creamy sauce.
- This casserole reheats beautifully—store leftovers in the refrigerator for up to 4 days.

Presentation Tips for Chicken Cordon Bleu Casserole
This creamy chicken cordon bleu casserole presents beautifully straight from the baking dish. Set the dish on a wooden trivet or heatproof mat in the center of your table for family-style serving. The golden breadcrumb topping is the star, so resist the urge to garnish too heavily—a simple scattering of fresh parsley provides color without overwhelming the visual appeal. For individual portions, use a large spoon to scoop servings onto warm plates, making sure to get some of that crispy topping on each portion. A sprig of fresh thyme on the side adds an elegant touch.
Perfect Pairings for Your Chicken Cordon Bleu Casserole
This rich, creamy casserole pairs best with wines that have enough acidity to cut through the cheese sauce. An unoaked Chardonnay is a classic choice, offering crisp apple notes that complement the Swiss cheese beautifully. Alternatively, a dry Riesling or Sauvignon Blanc provides refreshing contrast. For red wine lovers, a light Pinot Noir works surprisingly well.
For sides, keep things simple and fresh to balance the richness. A crisp Caesar salad, steamed green beans with lemon butter, or roasted asparagus spears are all excellent choices. Garlic bread is always welcome for those who want to soak up every last bit of that delicious sauce.
Recipe Variations for Chicken Cordon Bleu Casserole
Cheese Alternatives: While Swiss is traditional, Gruyère offers a nuttier, more complex flavor. Provolone or even a mild white cheddar work well too. For a stronger flavor, mix in some sharp white cheddar with the Swiss.
Pasta Options: Penne and rotini are ideal because their shapes hold the sauce well. Egg noodles create a more homestyle feel. Shells and farfalle also work beautifully. For low-carb, try cauliflower florets instead of pasta.
Protein Swaps: Turkey works wonderfully in place of chicken. For a special occasion, try veal—the traditional protein in European cordon bleu. Vegetarians can substitute chicken with extra-firm tofu or chickpeas.
Add Vegetables: Stir in frozen peas, sautéed spinach, steamed broccoli florets, or roasted asparagus pieces for added nutrition and color.
Dump-and-Bake Version: For an even easier version, mix uncooked pasta with Alfredo sauce, chicken broth, chicken, and ham. Bake covered for 40 minutes, then add toppings and bake uncovered until golden.
Frequently Asked Questions About Chicken Cordon Bleu Casserole
Can I make chicken cordon bleu casserole ahead of time?
Absolutely! Assemble the casserole completely but hold off on the breadcrumb topping. Cover and refrigerate for up to 24 hours. When ready to bake, add the topping and bake as directed, adding 10 to 15 minutes to the cooking time since it’s starting cold.
Can I freeze this casserole?
Yes! Prepare the casserole without the breadcrumb topping, cover tightly with plastic wrap and foil, and freeze for up to 3 months. Thaw overnight in the refrigerator before baking. Add the breadcrumb topping just before baking for maximum crispiness.
My cheese sauce is lumpy—what went wrong?
Lumpy sauce usually results from adding the milk too quickly or not whisking constantly. If you end up with lumps, strain the sauce through a fine-mesh sieve or blend it with an immersion blender until smooth.
Can I use cream of chicken soup instead of making sauce from scratch?
You can, but the homemade sauce is significantly better in both flavor and texture. If using canned soup, combine one can of cream of chicken soup with one cup of milk and half a cup of Swiss cheese for a simpler (though less impressive) version.
What’s the best way to reheat leftovers?
For best results, reheat individual portions in a 350°F oven for 15 to 20 minutes until heated through. The microwave works for quick reheating but will soften the breadcrumb topping. Add a splash of milk if the sauce seems too thick after refrigeration.
My husband doesn’t like Swiss cheese—what can I substitute?
Provolone, mild white cheddar, Havarti, or Gruyère are all excellent substitutes. The sauce may taste slightly different, but the dish will still be delicious. Some families even prefer a mozzarella and Parmesan combination.
