How to Make Chicken Cordon Bleu Casserole Recipe
Step 1: Prepare Your Oven and Pasta
Start by preheating your oven to 375°F (190°C) and greasing a 9×13-inch casserole dish with nonstick spray. Then boil your cavatappi pasta until it’s just al dente, about 7 to 8 minutes. This ensures your pasta holds its shape and bite throughout baking, preventing mushiness in the final dish.
Step 2: Mix the Creamy Sauce
In a large bowl, combine the cream of chicken soup, half & half, Dijon mustard, fresh parsley, seasoned salt, and black pepper. Stir until the ingredients are fully blended into a smooth, fragrant sauce that promises to coat every bit of pasta and chicken perfectly.
Step 3: Add Cheese, Chicken, and Pasta
Now fold in the shredded Swiss cheese, diced rotisserie chicken, and the cooked cavatappi pasta. Mixing these ingredients here ensures that every bite of your Chicken Cordon Bleu Casserole Recipe is rich and well-balanced, with pockets of melty cheese and savory chicken.
Step 4: Assemble the Casserole
Pour the combined mixture into your prepared casserole dish, spreading it evenly so it bakes uniformly. This step sets the stage for that golden bubbly finish we all love in a good casserole.
Step 5: Prepare and Add the Topping
In a small bowl, combine the melted butter, panko breadcrumbs, and grated Parmesan cheese. Sprinkle this mixture generously over the casserole to create a crunchy, flavorful golden crust that contrasts beautifully with the creamy base.
Step 6: Bake to Perfection
Place the casserole in your preheated oven and bake for 25 to 30 minutes. You want the topping golden brown and crisp, with the casserole bubbling around the edges—a clear sign that this Chicken Cordon Bleu Casserole Recipe is ready to serve.
How to Serve Chicken Cordon Bleu Casserole Recipe

Garnishes
A sprinkle of fresh parsley or finely chopped chives brightens the presentation and adds a fresh, herbal note that complements the rich flavors beautifully. For a touch of elegance, a few thin slices of lemon can also be served on the side to add a subtle zest.
Side Dishes
This casserole pairs wonderfully with light green salads dressed with vinaigrette to cut through the richness. Roasted vegetables like asparagus or Brussels sprouts add a nice earthy contrast, and for heartier appetites, some garlic bread on the side is always a crowd-pleaser.
Creative Ways to Present
For a festive dinner, serve the Chicken Cordon Bleu Casserole Recipe in individual ramekins topped with the crispy breadcrumb mixture. This makes for a charming presentation and is perfect for portion control. Alternatively, layering the casserole over a bed of fresh spinach just before serving adds a colorful, healthful twist.
Make Ahead and Storage
Storing Leftovers
Leftovers of this Chicken Cordon Bleu Casserole Recipe can be stored in airtight containers in the refrigerator for up to 3 days. To keep the topping crispy, store the topping separately if you anticipate leftover crust chunks.
Freezing
If you want to enjoy this dish later, it freezes exceptionally well. Assemble the casserole but do not bake it yet; cover tightly with foil and freeze for up to 2 months. When ready to eat, thaw overnight and bake as directed, adding a few extra minutes to ensure thorough heating.
Reheating
Reheat leftovers covered in the oven at 350°F (175°C) for about 20 minutes until warmed through. To refresh the crunchy topping, remove the cover during the last 5 minutes of reheating. This keeps every bite of your Chicken Cordon Bleu Casserole Recipe just as delightful as the first go-around.
FAQs
Can I use a different type of cheese?
Absolutely! While Swiss cheese is traditional and offers a nutty flavor, Gruyère or fontina can also work beautifully for that melty, creamy texture with a slightly different twist.
Is it necessary to cook the chicken beforehand?
This recipe uses rotisserie chicken for convenience, but any cooked chicken will do—grilled, baked, or even leftover chicken from another meal works wonderfully here.
Can I substitute the pasta for a gluten-free option?
Yes, just swap the cavatappi for your favorite gluten-free pasta. Keep cooking times in mind, as gluten-free pasta can vary in texture and bake time slightly.
What can I use instead of cream of chicken soup?
If you prefer homemade, a simple sauce made from butter, flour, milk, and chicken broth can replace the canned soup. It takes more effort but lets you control every ingredient.
How can I make this casserole more kid-friendly?
Simply reduce or omit the Dijon mustard to mellow the flavor, and consider adding a sprinkle of mild cheddar cheese on top to appeal to younger taste buds.
