• 3 cups shredded Swiss cheese: Melts beautifully for that classic chicken cordon bleu taste.
• 2 cups rotisserie chicken, diced: Tender, flavorful chicken that makes this casserole a meal.

• ¾ cup plain panko bread crumbs: Crunchy topping that adds contrast and texture.
• ¼ cup grated Parmesan cheese: Sharp and nutty, it boosts the topping’s flavor.

How to Make Chicken Cordon Bleu Casserole

Step 1: Preheat and Prepare Your Dish

Begin by heating your oven to 375°F (190°C). Grease a 9×13-inch casserole dish with nonstick spray to prevent sticking and make cleanup easier. This simple prep step sets you up for smooth sailing through the recipe.

Step 2: Cook the Pasta

Bring a large pot of salted water to a boil and cook the cavatappi pasta until just al dente—about 7 to 8 minutes. Drain well, making sure the pasta doesn’t become mushy, as you want it to hold its shape and texture in the casserole.

Step 3: Whip Up the Creamy Sauce

In a large mixing bowl, combine the cream of chicken soup, half & half, Dijon mustard, chopped parsley, seasoned salt, and black pepper. Stir until you achieve a smooth sauce that’s creamy and flavorful. This sauce is the magic glue that brings all the casserole’s layers together.

Step 4: Mix It All Together

Add the shredded Swiss cheese, diced rotisserie chicken, and cooked pasta to your sauce bowl. Fold everything together gently but thoroughly, ensuring each piece of pasta is coated, the chicken distributed evenly, and the cheese begins to melt into that beautiful mixture.

Step 5: Assemble the Casserole

Pour the combined mixture into your prepared casserole dish, smoothing it out evenly so each bite is balanced with pasta, chicken, and creamy sauce. This layering step sets the stage for baking perfection.

Step 6: Make and Add the Topping

In a small bowl, stir together melted butter, panko breadcrumbs, and grated Parmesan cheese until the crumbs are fully coated. Sprinkle this mixture evenly over the top of the casserole—it’ll create an irresistible crunchy crust that seals in all the tasty goodness while adding texture contrast.

Step 7: Bake to Golden, Bubbly Perfection

Place the casserole in your preheated oven and bake for 25 to 30 minutes, or until it’s bubbling around the edges and the breadcrumb topping is a gorgeous golden brown. Once baked, let it rest a few minutes to set before diving in.

How to Serve Chicken Cordon Bleu Casserole

Garnishes

A sprinkle of extra fresh parsley on top adds a pop of vibrant green and fresh aroma that complements the richness of the casserole. You can also try a light dusting of freshly grated Parmesan for an extra cheesy finish.

Side Dishes

This casserole pairs beautifully with crisp, bright side salads like a simple mixed greens salad with lemon vinaigrette or classic Caesar. Steamed green vegetables such as broccoli or green beans also provide a crunchy, fresh contrast to the creamy casserole.

Creative Ways to Present

For a fun twist, serve individual portions in ramekins topped with jewel-like chives or microgreens for an elegant plated look. Alternatively, add a wedge of lemon on the side to brighten each serving with a little citrus sparkle.

Make Ahead and Storage

Storing Leftovers

Store any leftover Chicken Cordon Bleu Casserole in an airtight container in the refrigerator for up to 3 days. This dish reheats beautifully and often tastes even better the next day once the flavors have melded further.

Freezing

You can freeze the casserole before baking. Assemble it fully, cover tightly with foil or plastic wrap, then freeze for up to 2 months. When ready, bake it from frozen adding about 15 extra minutes to the baking time for a piping-hot dinner.

Reheating

Reheat leftovers in the oven at 350°F (175°C) until warmed through and the breadcrumb topping regains its crispness. For a quicker option, microwave individual portions, though the topping won’t stay as crunchy.

FAQs

Can I use fresh chicken instead of rotisserie chicken?

Absolutely! You can cook and dice fresh chicken breasts or thighs, but rotisserie chicken adds extra flavor and saves time. Just be sure your cooked chicken is tender and seasoned well.

Is Swiss cheese necessary or can I substitute?

Swiss cheese is traditional and gives a nutty flavor that pairs beautifully with Dijon mustard, but Gruyère or provolone are great substitutes if you want a milder or slightly different cheesy profile.

Can I make this casserole gluten-free?

Yes! Use gluten-free pasta, substitute gluten-free cream of chicken soup, and swap regular panko breadcrumbs for a gluten-free variety. The casserole will still be delicious and comforting.

What can I do if I don’t have half & half?

You can mix equal parts whole milk and light cream to substitute for half & half, or just use whole milk for a lighter version, though the sauce might be a bit less rich.

How do I prevent the casserole from becoming soggy?

Make sure to drain your pasta well and avoid over-saucing. Also, the breadcrumb topping plays a crucial role in adding that crispy texture that balances the creamy filling perfectly.
