I love chicken cordon bleu. This has been on my to-do list since my husband and I went to a fundraiser back in May. They had the best chicken cordon bleu ever. I knew I could make the same flavors into a killer casserole.
My casserole version was a hit with my family. I wasn’t sure if the kids would like the Swiss cheese (honestly, I’m not a huge Swiss cheese fan), but it worked so well with this flavor combination that there were no complaints.

What is Chicken Cordon Bleu
Here is a little history on this iconic dish (compliments of Wikipedia):
A cordon bleu or schnitzel cordon bleu is a dish of meat wrapped around cheese (or with cheese filling), then breaded and pan-fried or deep-fried. (Veal) cordon bleu is made of veal pounded thin and wrapped around a slice of ham and a slice of cheese, breaded, and then pan fried or baked.[1] For chicken cordon bleu chicken breast is used instead of veal.[2]Ham cordon bleu is ham stuffed with mushrooms and cheese.[3]
The origins of cordon bleu as a schnitzel filled with cheese are in Switzerland, probably about the 1940s, first mentioned in a cookbook from 1949. The earliest reference to “chicken cordon bleu” in The New York Times is dated to 1967, while similar veal recipes are found from at least 1955.[6]
What kind of sauce goes with Chicken Cordon Bleu
We love this creamy lemon sauce on our Chicken Cordon Bleu Casserole. It is rich with the butter and cream cheese and the lemon juice, mustard, and white wine really help the flavors to pop.
Sometimes I just make the sauce and drizzle on chicken tenders or vegetables.
How to Make Chicken Cordon Bleu Casserole
First Step: Grease a 9 x 13 baking dish. Layer cooked chicken and ham in the casserole dish.
Second Step: Make the sauce. Season it to taste with salt and black pepper. It is easiest to mix the sauce with an electric mixer. Spread it on top.
Do I really need a whole stick of butter?
This is the most common question I get about this recipe. Yes, I do use 4 ounces, or one stick, of butter. Mix the room temperature sauce ingredients until smooth, and the butter will not separate.
Third Step: Layer on the cheese.
Fourth Step: Bake in the preheated oven until hot, bubbly, and golden. You can broil it for a minute or two at the end to brown the cheese. Watch it closely.
Storage
Store leftovers in the fridge for 4-5 days in an airtight container or covered with plastic wrap. The flavors develop further in the refrigerator, so it’s great to make ahead and reheat. I reheat individual portions in the microwave.
You can freeze this. Prep the casserole, but don’t bake. Cover with foil. Put in the freezer for up to 2 months. Let thaw overnight in the fridge and then bake as directed. This is ideal for busy nights!
Tips & Tweaks
I’ve had readers sub in other mild cheeses like provolone, mozzarella, or Havarti so feel free to tailor this to your family’s tastes.
One of the most important things for this recipe to make sure the chicken is nice and juicy. If the chicken is moist this will be moist and flavorful. If you are started with dry chicken I recommend making 1.5 times the sauce to compensate. Or even doubling it.
You can even save a step by baking chicken tenderloins, draining the cooking liquid, and then proceeding with the recipe. No shredding required!

Chicken Cordon Bleu Casserole – Low Carb
Ingredients
- 6 cups shredded cooked chicken (from about 2 lb chicken)
- 6 oz ham cut into bite size pieces
- 4 oz butter melted
- 6 oz cream cheese softened
- 1 tbsp dijon mustard
- 1 tbsp white wine (optional)
- 1 oz lemon juice
- 1/2 tsp salt
- 5 oz swiss cheese
Instructions
- Preheat the oven to 350. Put the chicken in the bottom of a 9 x 13 baking dish. Layer the pieces of ham on top.
- In a large bowl with an electric mixer combine the melted butter, softened cream cheese, white wine (if using), mustard, lemon juice, and salt. Blend until a thick sauce forms. Spread this sauce over the chicken and ham in the baking dish.
- Lay the slices of swiss cheese on top of the sauce. Bake for 30-40 minutes until hot.
- I broiled it for 2 minutes at the end so the cheese would get more golden and bubbly. If you decided to do that do not leave it unattended. It’s very easy to burn the cheese topping.

Very good but I’d recommend doubling the sauce. It seemed to disappear in the oven, but the flavor was outstanding regardless!
Very good but will definitely cut back on the butter!
Whole family loved it 😊
What kind of ham do you use? Is it deli sliced ham (like for sandwiches?) or is it cubed ham? Or a ham steak cut up?
I prefer to use cut up deli ham. But any of those will work. I prefer the deli ham because it adds that ham flavor without changing the texture like bigger pieces of ham do.
I made them into cups with carb balance street taco shells as the crust in a muffin pan!!
Delicious 😋.
Making this delicious recipe for the second time tonight. It’s quickly becoming a fav. Thank you Taryn 😊
It’s always nice to find a recipe my carb-loving bf and 9 y/o will also eat! I cooked two chicken breasts in the instant pot, shredded them, and put them in a 8×8 pan. Covered with ham, about half of a (diced) zucchini, then sauce. Topped with Swiss. Cooked for 35 mins, with a few more under the broiler.
It turned out really great, and the 8×8 made more than enough for three of us. We each ate 1/4, and there’s 1/4 leftover. I’ll definitely make it again, but I’ll use half as much butter and lemon juice next time. (I followed the recipe for the sauce, but it makes sense that you wouldn’t need ‘as much’ sauce for the smaller pan.) The zucchini also added a little liquid when it cooked down.
This was so good!! when I make it again, I will cut the butter in half. Maybe throw in a half bag of cauliflower rice to make it “firm up” a little. My husband and I loved it, thank you!
Good idea…but had to punch it up a bit.
– cut butter in half
– increase cream cheese by 50%
– added chunks of gruyere which I mixed in with the chicken
– spiced up the sauce with smoked paprika, cayenne, onion powder and cumin
Might need a little heavy whipping cream as well, probably 1/3 cup.
Giving 4/5 stars when you completely change the recipe isn’t helpful. The original recipe is great as is.
Meh…I liked it ok and followed the recipe exactly. If I make it again, I would use shredded cheese instead of sliced. It got too tough to eat in the finished dish.
my college age boys request this casserole constantly! they are keto followers, work out and very fit (dont know who raised them) lol my husband even enjoys it too. super easy with rotisserie chicken and i always have to make a double batch. thanks for recipe
I love this recipe! Do you know if this can be prepared ahead of time and frozen?
Yes, I’ve had readers freeze this successfully. I haven’t frozen it myself but I’d suggest freezing after you layer the ingredients (with cooked chicken) but before baking. Make sure your chicken isn’t dry.
I am just starting out on a keto/weight loss journey. It has been hard to find a recipe both my son and I can eat with minimal adjustments for him. We have also been looking for a good, easy cordon bleu recipe for a while now. This one is also keto so it’s a triple winner! There’s only two of us so I halved the meat amounts but left the sauce alone and just covered the top with cheese. I did sprinkle on some herbs de provence after the first taste. That put the flavor over the top. My son is not a fan of mustard in any form but he loved it! I served it with some buttered noodles for him. I will be making this again!
Hi, was just wondering..why the use of melted butter in the sauce? Is it just for taste?
Taste and texture. It’s delicious. Trust me. I could eat this sauce with a spoon. lol.
I’m giving this 5 stars since it is so good. But I think it needs some adjustments. 1 ounce lemon!?! I just juiced 1/2 lemon. I added about 1/2 tsp smoked paprika and the same garlic powder. Those were the only changes. My sauce wasn’t thick. Probably because of the lemon. It was still very good and melded nice even with runnier sauce. But it was so so rich! Next time I’m not doing butter but adding a nut milk. There will be a next time though. I thoroughly enjoyed it.
Delicious recipe. My husband wanted it again the next night!
I followed your instructions and even patted my ham dry but the sauce was quite liquidy – definitely butter. You called for 4 ounces of butter which is 8 Tablespoons. Should it be 4 Tablespoons? As my dear hubby loves butter he had no complaints!
(I think it would have helped if we would have let it sit but 10 minutes but it just looked too good to wait!)
Yes, it does thicken as it cools. I use a full 8 tablespoons of butter but if you want to use 4 tablespoons that would be fine.
