Ingredients You’ll Need

3 cups dry rotini pasta: This small, spiral-shaped pasta holds onto the sauce beautifully, but other types like ziti or penne would work just as well.
3 cups shredded Swiss cheese: Provides that creamy texture and nutty flavor that complements the other ingredients perfectly. You can substitute with shredded mozzarella or provolone if you like.
2 cups cooked and shredded chicken: I recommend using rotisserie or leftover chicken to save time on busy nights.
2 cups diced cooked ham: Holiday leftovers are a great way to use up extra ham, but deli ham also works like a charm.
10.5-ounce can condensed cream of chicken soup: This is the star of the sauce, providing sweetness and creaminess. You can opt for a healthier version or make your own if desired.
3-4 cloves garlic, finely minced: Fresh garlic has a lovely bite and aroma. If you’re in a pinch, about 1 teaspoon of garlic powder can substitute.
1 teaspoon Dijon mustard: Adds a tangy flavor that elevates the dish; avoid yellow mustard for this recipe.
½ teaspoon salt: Start with this amount and adjust to your taste.
½ teaspoon freshly ground black pepper: It gives a touch of warmth that balances the richness.
1 sleeve Ritz crackers, lightly crushed: Perfect for that extra crunch on top. You can use panko breadcrumbs for a slightly different texture.
2 tablespoons grated Parmesan cheese: This adds a lovely salty note to the topping.
¼ cup salted butter, melted: Rich buttery flavor that brings everything together. If you use unsalted butter, add a pinch of salt.
Fresh parsley, optional for garnishing: A little sprinkle on top right before serving makes for a beautiful presentation.

How to Make Chicken Cordon Bleu Casserole

Preheat the Oven: Begin by preheating your oven to 400°F. Spray a 9×13-inch casserole dish with cooking spray or grease it lightly, and set it aside.
Prepare the Pasta: In a large pot of boiling, salted water, add the 3 cups of dry rotini pasta. Cook until al dente according to package instructions, then drain, rinse under cool water, and set aside.
Mix the Filling: In a large bowl, combine the shredded Swiss cheese, cooked and shredded chicken, diced ham, condensed cream of chicken soup, minced garlic, Dijon mustard, salt, and pepper. Stir until everything is well coated.
Combine Pasta with Filling: Gently fold the drained pasta into the filling mixture, ensuring everything is evenly combined without overmixing.
Assemble the Casserole: Spoon the mixture into your prepared baking dish. Using a spatula, lightly smooth out the top without packing it down too firmly.
Make-Ahead Option: If you want to prepare this ahead of time, cover the unbaked casserole tightly with plastic wrap or foil and store in the refrigerator for up to 48 hours. When you’re ready to bake, take it out of the fridge one hour before to let it come to room temperature.
Prepare the Topping: In a large bowl (you can reuse the one from the filling mixture), add the crushed Ritz crackers. Using a wooden spoon, lightly break them into pieces, keeping some larger chunks for texture.
Mix the Topping: Stir in the grated Parmesan cheese and drizzle the melted butter over the cracker mixture. Toss until the crackers are lightly coated.
Top the Casserole: Evenly sprinkle the cracker topping over the casserole filling, making sure to cover it generously.
Bake the Casserole: Place the dish in the preheated oven and bake uncovered for about 20 minutes. Rotate the pan halfway through to help the topping brown evenly. If the crackers start to darken too quickly, cover the casserole with foil for the second half of baking.
Garnish and Serve: Once done, allow your casserole to cool for a moment. Optionally, garnish with fresh parsley before diving in!

Storing & Reheating

You can store any leftovers at room temperature for a few hours or in the fridge for up to 4 days, ideally in an airtight container to keep it fresh. Freezing is a great option too—just ensure you use a freezer-safe container. It can stay frozen for up to three months. When you’re ready to enjoy it again, simply thaw in the refrigerator overnight and reheat in the oven at 350°F for about 20–25 minutes until heated through, ensuring the topping remains crispy.

Chef’s Helpful Tips

Be careful not to overcook the pasta; al dente is perfect as it will continue to cook in the oven.
Using room temperature ingredients, especially when mixing the filling, ensures a nice, even consistency.
If you’re short on time, rotisserie chicken is a lifesaver. It’s flavorful and simplifies the prep!
Don’t skimp on the butter for the topping. It keeps the crackers from getting too dry.
Feel free to mix up the cheeses! Smoked gouda or a sharp cheddar can bring a fun twist to the flavors.

Not only does this Chicken Cordon Bleu Casserole shine with its rich, comforting flavors, but it also allows for creativity in the kitchen! You can use what you have, swap out ingredients, or even add veggies.

Can I use uncooked chicken in this casserole?

You can, but make sure to adjust your cooking time. Use thinly sliced or cubed raw chicken and ensure it’s thoroughly cooked to 165°F before serving.

Can I make this Chicken Cordon Bleu Casserole gluten-free?

Absolutely! Swap the rotini pasta for a gluten-free variety and use gluten-free crackers or breadcrumbs for the topping.

How do I refresh leftovers?

To refresh leftovers, add a splash of chicken broth or cream before reheating in the oven to restore moisture. Cover it with foil as it warms to prevent the top from getting too brown.

Can I customize the cheese used in this casserole?

Yes! While Swiss cheese is traditional, experimenting with other cheeses like Monterey Jack or even a blend of your favorites can add a unique flavor profile.
