How to Make Chicken Cordon Bleu Casserole Recipe
Step 1: Prepare Your Baking Dish
Start by preheating your oven to 350ºF to ensure it’s nice and hot for baking. Lightly spray a 9×9-inch baking dish with cooking spray to prevent sticking and make for easy cleanup later. This simple prep step sets the stage for your casserole to bake evenly and come out perfect every time.
Step 2: Mix the Filling
In a large bowl, combine the cooked chopped chicken, diced ham, sour cream, grated Swiss cheese, Dijon mustard, onion powder, garlic powder, and the can of cream of chicken soup. This mixture is the flavorful heart of your Chicken Cordon Bleu Casserole Recipe. Stir until all ingredients are fully incorporated, creating a creamy, satisfying blend that will fill your casserole with rich, balanced flavors.
Step 3: Assemble in the Baking Dish
Spread the chicken and ham mixture evenly into the prepared baking dish. Make sure it’s level to ensure even baking and that every bite gets that wonderful combination of protein and creamy sauce. This is where the magic really starts to come together before baking.
Step 4: Add the Topping
Combine the crushed Ritz crackers and melted butter in a small bowl, mixing until the crumbs are evenly coated. Sprinkle this buttery cracker topping generously over the chicken mixture. This topping will transform into a golden, crispy layer that contrasts beautifully with the creamy interior.
Step 5: Bake Until Golden
Bake the casserole uncovered for 30 to 40 minutes until it’s bubbling around the edges and the cracker crust is a stunning golden brown. This baking time is perfect to meld the flavors while achieving that irresistible crunchy topping that makes this Chicken Cordon Bleu Casserole Recipe stand out.
How to Serve Chicken Cordon Bleu Casserole Recipe

Garnishes
For a fresh pop of color and flavor, sprinkle chopped fresh parsley or chives on top after baking. These bright greens add a lovely herbal note that balances the richness of the casserole, giving every bite a little extra zing and a polished presentation.
Side Dishes
This casserole pairs wonderfully with simple, crisp sides like a light mixed green salad with vinaigrette, steamed green beans, or roasted asparagus. These vegetables bring freshness and crunch to your meal, complementing the creamy warmth of the casserole perfectly without overpowering it.
Creative Ways to Present

You can also serve it atop fluffy mashed potatoes or buttered noodles to turn it into an extra comforting feast that feels like a true indulgence.
Make Ahead and Storage
Storing Leftovers
After enjoying your casserole, any leftovers can be kept in an airtight container in the refrigerator for up to 3 days. This makes for an easy second meal that just needs reheating, preserving all those delicious flavors and creamy textures.
Freezing
You can freeze this casserole either before baking or after it has cooled down. Store it in a freezer-safe container or wrap tightly with foil and plastic wrap. It will keep well for up to 2 months, making it a fantastic option for meal prep or busy weeknights when time is tight.
Reheating
Reheat leftovers in the oven at 350ºF until warmed through, about 20 minutes, to maintain that crispy topping. Alternatively, the microwave works for a quick fix but might soften the crust. For best texture, reheat uncovered and watch carefully to avoid drying out.
FAQs
Can I use different cheeses in this Chicken Cordon Bleu Casserole Recipe?
Absolutely! While Swiss cheese is traditional and provides that signature nutty flavor, you can experiment with Gruyère, mozzarella, or even cheddar if you prefer a sharper or creamier twist. Just make sure the cheese melts well for that perfect creamy texture.
Is it necessary to use cooked chicken for this recipe?
Yes, cooked chicken is essential because the casserole primarily needs to bake long enough to meld flavors and crisp the topping, not to cook raw meat. Using pre-cooked chicken saves time and ensures the chicken stays moist and tender inside the casserole.
Can this Chicken Cordon Bleu Casserole Recipe be made gluten-free?
Definitely! Swap out the Ritz crackers for gluten-free crackers, and ensure the cream of chicken soup is gluten-free as well. This simple substitution lets you enjoy the same great flavors without gluten concerns.
What can I substitute for sour cream if I don’t have any?
If you don’t have sour cream on hand, Greek yogurt is a fantastic substitute that also adds some tanginess and creaminess. Just make sure to use plain, full-fat yogurt for the best texture and flavor.
Can I add vegetables to this casserole?
Yes, you can add cooked vegetables like broccoli, peas, or mushrooms for added nutrition and texture. Just be mindful not to add too much moisture or your casserole might become a bit soggy. Lightly steamed or sautéed veggies are best.
Final Thoughts
This Chicken Cordon Bleu Casserole Recipe is the ultimate comfort food that brings all the classic flavors of a timeless dish into a cozy, easy-to-make meal. It’s perfect for busy weeknights, family dinners, or any time you want to treat yourself to something warm, cheesy, and utterly satisfying.
