Easy Chicken Cordon Bleu Casserole

When I was in college, I had Classic Chicken Cordon Bleu for the first time. And I loved it so, so much. 

Several years later, when I was married and experimenting with recipes, I got to thinking about that Chicken Cordon Bleu and figured it would be pretty easy to get the same flavors in an easy chicken casserole recipe.

If you’ve ever made traditional chicken cordon bleu – which is pure comfort food, by the way – you know it can take a while with all the extra steps. 

This casserole gives you those same great flavors in a fraction of the time. You can use rotisserie chicken or leftover chicken, and it comes together quickly in one dish.

This easy recipe is in our family’s regular meal rotation – we eat it at least once or twice a month.

Tools Needed

• 9×13-inch baking dish
• Large microwave-safe bowl
• Small mixing bowls
• Whisk
• Mixing spoon or spatula
• Fork (for fluffing stuffing)
• Measuring cups and spoons

Ingredients

These ingredients are all easily found at your local grocery store and come together to make a delicious casserole!

• Cornbread stuffing mix
• Butter
• Hot water
• Cooked diced chicken (boneless skinless thighs, breasts, or pulled rotisserie chicken)
• Ham, diced (sandwich meat or deli ham)
• Swiss cheese, diced
• Cream of chicken soup
• Whole Milk
• Dijon mustard or spicy brown mustard
• Panko bread crumbs
• Butter, melted

How to Make Chicken Cordon Bleu Casserole

With only 10 minutes of prep and 30 minutes in the oven, this recipe is fast and easy – and perfect for busy weeknights!

1. Preheat the oven to 350°F. 
2. In a microwave-safe bowl, combine the stuffing mix, water, and butter. Microwave for 5–6 minutes, then fluff the stuffing with a fork.

3. Add the diced chicken, chopped ham, and shredded cheese to the hot stuffing and stir until evenly combined.
4. Spray a 9×13-inch casserole dish with nonstick spray, then spread the stuffing mixture evenly in the bottom of the pan.

5. In a small bowl, whisk together the soup, milk, and mustard.
6. Pour the mixture evenly over the casserole and spread out evenly to the edges of the pan.

7. In another small bowl, stir together the breadcrumbs and melted butter until well coated. Sprinkle the breadcrumb mixture evenly over the top of the casserole
8. Bake for 35–40 minutes, or until hot and bubbly. For an extra crispy topping, switch the oven to broil for the last 1–2 minutes to brown the breadcrumbs. Watch closely so it doesn’t burn.

9. Enjoy!

Recipe Variations

Chicken Cordon Bleu Casserole with Stuffing

Instead of cornbread stuffing, you could use traditional bread stuffing. As a southern girl, I can’t bring myself to eat that stuff, but I’m sure it would be fine 😉

Using Raw Chicken

If you only have raw chicken breasts or thighs on hand (boneless skinless), dice them into bite-sized pieces and cook them in a skillet with olive oil until no longer pink before assembling the casserole.

Pasta Variation

You can also make this casserole with pasta instead of stuffing. Simply cook a short pasta such as penne, rotini, or bowtie until al dente and use it in place of the cornbread stuffing. Toss the cooked pasta with the diced chicken, ham, and Swiss cheese, then pour the soup, milk, and mustard sauce over the mixture. Transfer to the casserole dish, top with the buttery Panko breadcrumbs, and bake as directed until hot and bubbly.

Pro Tips

• Use good Swiss cheese for the best flavor and melt.
• Don’t skip the Dijon mustard. It adds a tangy depth that makes this taste like traditional chicken cordon bleu.
• This recipe is a great way to use up leftover chicken, so keep it in mind the next time you have extras from dinner.
• If using pasta, cook it just until al dente since it will continue cooking in the oven.
• Let the casserole rest before serving so the sauce stays creamy instead of running.

What to Serve with Chicken Cordon Bleu Casserole

This delicious dish goes well with so many sides. We most often serve it with green beans or broccoli, or sometimes green salads.

Storage and Reheating

Store leftovers in an airtight container in the refrigerator for 3-4 days. The flavors get even better after sitting overnight.

To reheat, cover the casserole with foil and warm it in the oven until heated through. You can also microwave individual portions, though the topping won’t stay quite as crispy.

Can You Freeze Chicken Cordon Bleu Casserole?

Yes, this casserole freezes very well. Assemble the casserole but do not bake it. Wrap tightly and freeze for up to three months.

When ready to bake, thaw overnight in the refrigerator and bake as directed, adding a little extra time if needed.
