🧾 Ingredients

This is an overview of the ingredients. You'll find the full measurements and instructions in the green recipe card (printable) at the bottom of the page.

Labeled ingredients for this recipe.

📖 Variations

  • For the Chicken: Use shredded chicken breast, chopped thighs, frozen (and thawed) pulled meat, or a ready-to-go rotisserie chicken from your local grocery store.
  • Swap the Ham: You can chop up some deli ham if you don't have any precooked. I ask for extra thick slices so that it's easier to cube.
  • Make It a Full Meal: Stir in some cooked rice and a bag of frozen peas or carrots (or both!) and you've got carbs, veggies, and protein!
  • Add Some Spice: It's not exactly part of the classic dish, but you can substitute the ground mustard with smoked paprika or a pinch of cayenne pepper for a little kick.
  • Make it Southwest-Style: Add a can of diced tomatoes with green chilies, and substitute the cheese for Pepper Jack or Monterey Jack. 
  • Add Extra Veggies: Mushrooms and chopped asparagus are also yummy in cordon bleu casserole.
  • Make it Deluxe: Substitute the provolone with Swiss cheese slices or smoked Gouda. Then, swap the onion and garlic powder for the real thing. Carmelize the onions, first, if you have some extra time.
  • Other Helpful Ideas: Instead of mustard powder, add a bit of your favorite dijon mustard. Cream of chicken soup works in place of the mushroom. Also, garnish with some fresh herbs when serving, like parsley or rosemary.

🔪 Instructions

This is an overview of the instructions. Full instructions are in the green recipe card at the bottom of the page.

Step by step images showing how to make chicken cordon bleu casserole.
  1. In a large bowl, mix the soup, milk, and spices.
  2. Stir in the chicken and ham.
  3. Pour mixture into a prepared baking dish.
  4. Cover the top of the casserole with cheese, bread crumbs, and melted butter. Bake.

🧊 Make it a freezer meal

I love having several extra meals in my freezer but not all recipes can be frozen. Luckily this one freezes like a champ.

Double or quadruple the recipe and then follow the instructions below to have a delicious dinner at your fingertips.

Don't re-freeze the leftovers.

How to assemble

  1. Spray a 9x9 casserole dish with no-stick cooking spray or oil it. Disposable aluminum casserole pans work fine.
  2. In a large mixing bowl, mix the condensed cream of mushroom, milk, dry mustard, onion powder, garlic powder, salt, and ground pepper.
  3. Whisk to combine.
  4. Add the diced ham and the cooked chicken. Mix to coat them with the condensed soup mixture.
  5. Pour into the prepared baking dish. Spread evenly in the pan.
  6. Place the cheese slices on top.
  7. Sprinkle the grated Parmigiano cheese on top of the Provolone slices.
  8. Cover tightly with plastic wrap then wrap with aluminum foil. This will help prevent freezer burn.
  9. Label it with the name and date.
  10. Freeze for up to 4 months

How to thaw and bake

  1. The night before you plan to bake the casserole remove it from the freezer. Take the aluminum foil off but leave the plastic wrap on and put in the refrigerator to thaw.
  2. About an hour before serving remove the plastic wrap.
  3. Top the casserole with the Panko breadcrumbs.
  4. Bake at 350F for 30-40 minutes. If the breadcrumbs brown to fast tent a piece of aluminum foil loosely over the top.
  5. Casserole will register 165F in the center when you stick an instant-read thermometer in the center.
  6. If the chicken cordon bleu casserole wasn't completely thawed it may take a few minutes more.

Bake from frozen

I get it. Sometimes you don't think about getting it out to thaw or life happens unexpectedly and you have a frozen casserole on your hands.

No worries!

  • Remove casserole from freezer.
  • Take off the aluminum foil AND the plastic wrap.
  • Do NOT add Panko crumbs yet. Put the aluminum foil back on the dish, sealing it tightly.
  • Bake at 350F for 40 minutes. Make sure it's not still frozen in the middle. if it is return to the oven for 10 minutes.
  • Remove from oven, remove the aluminum foil, and add the Panko crumbs and return to the oven for 10 to 15 minutes.
  • Serve.

🥫 How to store leftovers

Chicken cordon bleu casserole is an easy weeknight dinner with leftovers that taste just as good as the first night—as long as they're stored and reheated properly!

Refrigerate or freeze

Once the meal has cooled, cover the casserole dish with a lid or some plastic wrap.

You can also scoop the casserole leftovers into an airtight container but try to keep the breadcrumb topping facing up. Refrigerate for up to three days.

You can also freeze leftovers for up to 3 months.

How to reheat leftovers

Avoid using the microwave to rewarm the leftovers, for best results. It's similar to this chicken piccata casserole - it'll work okay, but the topping won't be as crisp.

Instead, place the leftover chicken cordon bleu casserole into a ramekin or heat-proof bowl. Then, warm it up in an air fryer set at 350 F degrees for three to four minutes.

You can also use a preheated oven if you don't have an air fryer. It'll work the same way to heat up the creamy insides while keeping the panko breadcrumbs crisp. However, it'll take a little longer than in an air fryer.

💭 Things to know

Expert Tip: Since all of the meat used in this casserole is fully cooked, you might not need to bake it for the full length of time. It just needs to warm through. Don't overcook it or it'll dry out.

  • "Parmigiano" generally refers to a type of Parmesan cheese that has been aged for a few years. If you can't find it, use grated Parmesan.
  • This delicious casserole is great as is, but it's even better served over a bit of rice or buttered egg noodles. That way, you can enjoy every bit of the cheesy, saucy goodness.
  • Chicken cordon bleu casserole makes a great freezer meal. Assemble it in an aluminum foil casserole pan (leave off the breadcrumbs, though) and freeze until you're ready to eat. Bake until warmed through, adding the breadcrumbs for the last 20-30 minutes. It could take up to an hour and a half to bake fully from frozen.
  • The aroma of the creamy sauce is heavenly, but don't dig in right away. The casserole is piping hot straight out of the oven.

👩‍🍳 FAQs

What is chicken cordon bleu?

A classic chicken cordon bleu recipe refers to a flattened piece of chicken stuffed with (or wrapped around) a piece of ham and some cheese. Then, the whole thing is coated in crispy breadcrumbs and fried. It's yummy, but kind of an involved process.

Why is it spelled cordon "bleu" and not "blue?"

"Cordon bleu" is a French term for "blue ribbon." And, let me tell you, after one bite of this easy chicken cordon bleu casserole, you'll want to award it all of the ribbons!

Can I use sour cream or cream cheese in the sauce?

I don't recommend fully replacing the cream of mushroom soup or milk with sour cream or cream cheese. However, if you're looking to add a bit more richness, you can definitely add a spoonful of either into the sauce mixture.

Notes

Storage:
Once it has cooled, cover the casserole dish with a lid or some plastic wrap. You can also scoop the casserole leftovers into an airtight container, but try to keep the breadcrumb topping facing up. Refrigerate for a maximum of three days.
You can freeze the casserole for up to 3 months either baked or unbaked. It's best if you leave the topping off until just before baking.
For best results, avoid using the microwave to rewarm the leftovers. It'll work okay, but the topping won't be as crisp. For best results place the leftovers in a ramekin or heat-proof bowl, in the air fryer at 350 degrees F for 3 to 4 minutes or until the desired temperature.
Tips:
  • Since all of the meat used in this casserole is fully cooked, you might not need to bake it for the full length of time.
  • "Parmigiano" generally refers to a type of Parmesan cheese that has been aged for a few years. If you can't find it, use freshly grated Parmesan.
  • Chicken cordon bleu casserole makes a great freezer meal. Be sure to scroll back up to the Freezer meal section for instructions.
  • The aroma of the creamy sauce is heavenly, but don't dig in right away - give it a minute or two to rest.
