Ingredients You’ll Need

The beauty of this dish lies in a handful of reliable ingredients that come together for bold, irresistible flavor. Each one adds something essential — whether it’s creaminess, depth, or that signature melty, cheesy pull. Here’s everything you’ll need:

Cooked chicken (3 cups, shredded or chopped): Rotisserie chicken makes this step a breeze, and ensures every bite is juicy and tender.
Diced ham (1 1/2 cups): Adds a salty, savory touch that’s classic in cordon bleu recipes.
Swiss cheese (2 cups, shredded): Melts beautifully for that signature creamy, slightly nutty flavor; Gruyère or mozzarella also work in a pinch.
Cream of chicken soup (1 can, 10.5 oz): The backbone of the sauce, creating a rich and creamy base without extra fuss.
Sour cream (1/2 cup): Adds silkiness and a welcome tang that keeps everything luscious.
Dijon mustard (1 tablespoon): Lends a gentle sharpness and brings all the flavors together.
Garlic powder (1/4 teaspoon): For a mellow, aromatic layer of flavor throughout the casserole.
Onion powder (1/4 teaspoon): Another aromatic boost, giving you that slow-cooked depth instantly.
Black pepper (1/4 teaspoon): Just enough to balance the creamy richness without overpowering.
Seasoned breadcrumbs (1 cup): The magic for a crispy, toasty golden crust.
Melted butter (2 tablespoons): Helps the breadcrumbs brown up perfectly, adding a hint of richness.
Chopped parsley (for garnish, optional): A fresh pop of color and flavor on top — it’s optional, but delightful.

How to Make Chicken Cordon Bleu Casserole

Step 1: Prep the Oven & Baking Dish

Start by heating your oven to 375°F so it’s hot and ready when your casserole is assembled. Give your 9×13-inch baking dish a quick coat of nonstick spray or a swipe of butter. This simple step means your Chicken Cordon Bleu Casserole will lift out in perfect, creamy squares every single time.

Step 2: Mix Up the Creamy Filling

In a large mixing bowl, bring together your cooked chicken, diced ham, most of the shredded Swiss cheese (save a little for topping), cream of chicken soup, sour cream, Dijon mustard, garlic powder, onion powder, and black pepper. Stir until everything is completely combined and evenly coated — you’ll start to see (and smell!) all those rich, savory flavors melding beautifully.

Step 3: Assemble the Casserole

Spread your creamy chicken and ham mixture into the prepared baking dish, pressing it gently into all the corners. Smooth it out with a spatula so the top is level, making it easier to add that irresistible crunchy topping later.

Step 4: Make the Buttery Breadcrumb Topping

In a small bowl, stir together the seasoned breadcrumbs and melted butter. This creates the ultimate golden, savory crust for your Chicken Cordon Bleu Casserole. Sprinkle the buttered crumbs evenly over the top of the casserole, then follow with the rest of your Swiss cheese for extra meltiness.

Step 5: Bake Until Golden and Bubbly

Slide your assembled casserole into the oven, uncovered, and bake for 25 to 30 minutes. You’re looking for the edges to bubble and the top to turn perfectly golden. Once it’s ready, let your casserole rest for about 5 minutes before serving — this helps all those luscious layers hold together.

How to Serve Chicken Cordon Bleu Casserole

Garnishes

A sprinkle of fresh chopped parsley not only looks gorgeous but also adds a hint of brightness that cuts through the richness. You could also try snipping chives over the top or adding a few lemon zest curls for a little extra color and zing. The finishing touch goes a long way in making your Chicken Cordon Bleu Casserole look extra inviting at the table.

Side Dishes

Chicken Cordon Bleu Casserole is so satisfying on its own, but pairing it with a crisp green salad or some simply steamed green beans really rounds out the meal. If you’re craving something heartier, roasted potatoes or buttered noodles make terrific companions for all that ultra-creamy sauce.

Creative Ways to Present

If you want a fun twist, portion the casserole into individual ramekins for a dinner party or Sunday lunch — it’s personal and a little fancy! Or, scoop it onto toasted bread rounds for a warm appetizer. However you serve it, everyone will love discovering the layers of flavor baked into every bite of this Chicken Cordon Bleu Casserole.

Make Ahead and Storage

Storing Leftovers

Leftover Chicken Cordon Bleu Casserole keeps beautifully in the refrigerator. Transfer any cooled portions to an airtight container (or simply cover the baking dish with foil or plastic wrap) and store for up to 3 days. The flavors deepen overnight, making leftovers extra delish for lunch the next day!

Freezing

This casserole is a dream for make-ahead meals! To freeze, assemble the casserole up to the breadcrumb step, then wrap it tightly in both plastic wrap and foil. It will keep nicely for up to 2 months. When you’re ready to serve, just thaw overnight in the fridge, add the breadcrumb and cheese topping, and bake as directed.

Reheating

To reheat, cover individual servings with foil and warm in a 350°F oven until heated through (about 15-20 minutes). For a crisper topping, uncover during the last 5 minutes. The microwave works in a pinch too — just use a lower power setting so the cheese melts gently and the chicken stays moist.

FAQs

Can I use rotisserie chicken instead of cooking my own?

Absolutely! Rotisserie chicken is my personal shortcut for getting this Chicken Cordon Bleu Casserole on the table fast. Just shred or chop, and you’re good to go.

What can I use instead of Swiss cheese?

Swiss cheese is traditional, but Gruyère gives wonderful flavor too. If you prefer something even milder, mozzarella or a mix of your favorite cheeses will still taste fantastic.

Can Chicken Cordon Bleu Casserole be assembled ahead of time?

Definitely! Assemble everything (except the breadcrumb topping) up to a day in advance, cover tightly, and refrigerate. When you’re ready to bake, just add the topping and pop it in the oven.

Is this dish gluten free?

Not as written, because of the breadcrumbs and canned soup. But swap in gluten-free breadcrumbs and use a gluten-free condensed soup, and your Chicken Cordon Bleu Casserole will be entirely gluten free!

How do I know when the casserole is ready?

The casserole is done when the top is golden and the edges are bubbling—usually after 25 to 30 minutes in the oven. Let it rest for a few minutes before serving so it sets up nicely.

Final Thoughts

There’s just something magical about the combination of savory chicken, smoky ham, and creamy cheese in this Chicken Cordon Bleu Casserole. It’s a dish that always brings smiles (and second helpings!) around the table. Give it a try soon and see why it’s one of my go-to comfort food favorites — you might just find it becomes a regular star in your dinner rotation too.
