How to Make Chicken Cordon Bleu Casserole Recipe
Step 1: Preheat and Prepare
Start by preheating your oven to 350°F (175°C). Lightly grease a baking dish to ensure the casserole doesn’t stick and comes out easily once baked. This simple prep step sets the stage for a hassle-free cooking experience.
Step 2: Mix the Filling
In a large bowl, combine the shredded cooked chicken, chopped turkey or chicken slices, shredded Swiss cheese, and the Dijon mustard. Stir these ingredients together gently but thoroughly, making sure every bite will have that perfect balance of meat and cheese.
Step 3: Add Soup and Season
Pour in the cream of chicken soup, which adds creamy richness and a comforting texture to this casserole. Season with salt and pepper to taste, then stir the mixture until everything is evenly incorporated. This step ensures the casserole will be bursting with flavor throughout.
Step 4: Assemble and Add Topping
Transfer the creamy chicken mixture into the prepared baking dish, spreading it out evenly. Sprinkle the breadcrumbs over the top to create that irresistible golden crust. This crunchy layer makes the casserole truly special.
Step 5: Bake to Perfection
Bake in your preheated oven for 25 to 30 minutes. Keep an eye out for a bubbly casserole with a nicely browned breadcrumb topping. This indicates your Chicken Cordon Bleu Casserole Recipe is ready to be enjoyed.
Step 6: Let it Rest and Serve
Once baked, allow the casserole to cool for a few minutes before serving. This brief rest helps it set a little, making portions easier to serve and ensuring every bite is just perfect.
How to Serve Chicken Cordon Bleu Casserole Recipe

Garnishes
Fresh herbs like chopped parsley or thyme add a lovely pop of color and brightness to balance the richness of the casserole. A light sprinkle of freshly grated Parmesan cheese on top right before serving can add an extra layer of flavor that your guests will adore.
Side Dishes
This Chicken Cordon Bleu Casserole Recipe pairs beautifully with a crisp green salad or some steamed seasonal vegetables to add freshness and crunch. Roasted potatoes or a simple buttered rice pilaf also complement the creamy casserole while keeping the meal satisfying and well-rounded.
Creative Ways to Present
For a charming twist, serve small individual portions in ramekins or mini casserole dishes. This not only looks elegant but also makes it easy for guests to enjoy without fuss. Alternatively, pair it with crusty bread to scoop up every last bit of creamy goodness — it’s a guaranteed hit at any table.
Make Ahead and Storage
Storing Leftovers
Leftover Chicken Cordon Bleu Casserole can be stored in an airtight container in the refrigerator for up to 3 days. This makes it perfect for easy lunches or next-day dinners when you want something comforting and quick.
Freezing
You can freeze the casserole either before baking or after. If freezing before, assemble it in a freezer-safe dish and cover tightly with foil and plastic wrap. It will keep well for up to 2 months. When ready to use, thaw overnight in the fridge and then bake as directed.
Reheating
To reheat, warm individual portions in the microwave or heat the whole casserole in a 350°F oven until hot and bubbling again. Adding a little extra cheese on top during reheating can refresh the dish and make it taste just like fresh.
FAQs
Can I use pre-cooked rotisserie chicken instead of cooked chicken?
Absolutely! Using rotisserie chicken is a fantastic shortcut that adds extra flavor and saves time. Just shred it well before mixing into the casserole.
Is it possible to make this recipe gluten-free?
Yes, simply substitute the regular breadcrumbs with gluten-free breadcrumbs or crushed gluten-free crackers. The rest of the ingredients are naturally gluten-free, making this dish adaptable for special diets.
Can I use a different cheese instead of Swiss?
Definitely. Gruyere, mozzarella, or even cheddar can work well if you want to experiment with flavors or use what you have on hand. Each cheese will bring a unique twist to the casserole.
What can I do if I don’t have cream of chicken soup?
You can easily make a homemade version by combining butter, flour, chicken broth, and milk to create a creamy sauce. This will give you a fresher taste and control over the seasoning.
How do I make this casserole more kid-friendly?
To suit younger palates, reduce the mustard a bit or leave it out entirely, and consider adding a little more cheese for creaminess. You can also mix in some finely chopped cooked broccoli or carrots for added nutrition and mild flavor.
Final Thoughts
