Chicken Cordon Bleu Casserole is a cozy twist on a classic dish, combining tender chicken, ham, and melty Swiss cheese all baked together with a crunchy topping. It’s got that lovely mix of creamy and crispy textures that make it feel like a special meal but without the fuss. The flavors are familiar and comforting, perfect for a family dinner or anytime you want something satisfying.
I love making this casserole when I want a meal that feels fancy but comes together quickly. It’s one of those dishes that gets better the next day, so I often make enough to have leftovers—though it rarely lasts that long in our house! Adding a touch of Dijon mustard to the sauce gives it a little kick that I always find myself sneaking more of.
My favorite way to serve this is with a simple green salad or some steamed veggies on the side to balance out the richness. It’s also great with a crusty bread to soak up any extra sauce. This casserole is the kind of meal that brings everyone to the table happily, and for me, that’s what cooking is all about.
Key Ingredients & Substitutions
Chicken and Ham: Using cooked chicken breast gives a mild flavor and tender texture. Leftover chicken or rotisserie chicken work great. For ham, pre-cooked deli ham or even turkey ham are good substitutes if you want a lighter option.
Pasta: Egg noodles add a soft, hearty feel, but you can swap with any pasta you like, such as penne or rotini. Just cook it al dente to avoid mushy casserole.
Swiss Cheese: This cheese melts beautifully, delivering the traditional cordon bleu taste. If you can’t find Swiss, Gruyère or mozzarella make excellent choices for meltiness and flavor.
Cream of Mushroom Soup: This adds creaminess and depth. If you prefer, use cream of chicken soup or a homemade white sauce to keep it gluten-free and fresher tasting.
Dijon Mustard: Just a teaspoon lifts the flavors wonderully. If you don’t have Dijon, yellow mustard or even a dash of horseradish can add a nice zing.
How Do I Keep the Casserole Creamy Without Getting Soggy?
Balancing creaminess and texture is key in this dish. Here’s how to ensure it stays just right:
- Cook pasta until just al dente—it will continue cooking in the oven, so this prevents it from turning mushy.
- Use well-drained chicken and ham to avoid extra moisture leaking into the casserole.
- Combine your creamy ingredients (soup, sour cream, mayo) thoroughly so every bite is smooth, but avoid adding too much liquid.
- Sprinkle crushed potato chips or breadcrumbs on top for a crispy contrast that keeps the casserole from feeling heavy.
- Let the casserole rest 5-10 minutes after baking before serving, allowing it to set and thicken slightly.
Equipment You’ll Need
- 9×13-inch baking dish – perfect size for layering and baking the casserole evenly.
- Large mixing bowl – makes it easy to combine the chicken, ham, noodles, and cheese.
- Medium bowl – for whisking the creamy sauce ingredients smoothly.
- Whisk – helps blend the sauce without lumps.
- Wooden spoon or spatula – great for mixing ingredients without crushing pasta.
Flavor Variations & Add-Ins
- Swap ham for cooked bacon or prosciutto for a smoky twist and rich flavor.
- Use Gruyère or mozzarella cheese instead of Swiss for a different melty, mild taste.
- Add sautéed mushrooms or spinach for extra veggies and earthiness.
- Mix in a teaspoon of smoked paprika or cayenne for a little heat and depth.

Yes, you can use frozen chicken, but be sure to fully thaw it in the refrigerator before cooking. This helps ensure even cooking and prevents excess moisture in the casserole.

Absolutely! Prepare the casserole up to the baking step, cover it tightly, and refrigerate for up to 24 hours. When ready, bake as directed, adding a few extra minutes if baking from cold.
What Can I Substitute for Cream of Mushroom Soup?
You can use cream of chicken soup or make a simple homemade white sauce to keep it gluten-free. A blend of butter, flour, milk, and seasonings works great as a creamy base.
How Should I Store Leftovers?
Store any leftovers in an airtight container in the refrigerator for up to 3 days. Reheat in the oven or microwave until warm, stirring occasionally for even heating.
