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.

What can I use to replace the wine?
It is optional. You can use a little chicken broth if you need to thin the sauce.
What can I use to replace the ham? I went through many of the comments below and didn’t see a substitute for ham.
You can just leave it out if you want. If you don’t eat pork smoked turkey would add a nice flavor.
New Seasons market carries a black forest Turkey that would give the flavor without the pork.
We were out of ham, so I used bacon cut into bit sized pieces instead. Delicious!!!
I’ve never cooked with wine before but always love it when others do. What’s a good, dry wine to cook with (I only drink moscato and I know that won’t work 😂)
Pinot Grigio is my fave because I don’t mind drinking a glass too 🙂
Is there a substitute for the dijon mustard and if so what is it ?
You can just omit it. Or use any other mustard or a pinch of dry mustard.
Does the pan need to be greased ahead of time?
No, I don’t normally grease the pan for this. If you’d like to you can.
Oh my Goodness this was good! Even BETTER the next day reheated in the toaster oven, not the microwave. I served it w/ homegrown frozen green beans. That sauce could be used just with green beans for an amazing side dish! It definitely needed double the sauce. I’m not a huge swiss cheese fan, but mixed with the cream cheese and butter, it was perfect! This is “company worthy” as we say at our house. I actually had a guest the first time I made it and she loved it too. And people think we are suffering without all the carbs… pffft! LOL
Excellent! Hubs loved it. Added Costco’s plain non-fat yogurt to the sauce, along with butter, wine, lemon and cream cheese. A fantastic sauce which could do double duty as a dip for appetizers. At least that’s what I’m planning to do with it next Christmas. Will make this dish again (maybe try it w/o the butter). Thank you!!!!
Thank you so much for this recipe! It’s the first “low-carb” casserole my kids actually liked!
The absolutely best Keto friendly casserole I have made yet!! Thank you for posting this! lol Simply delishly yummy!! 🤤😋
I’m allergic to citrus; any suggestions on sauce alternatives?
You can just leave the lemon juice out. I’d recommend using the optional white wine if you are leaving out the lemon. Otherwise, add a little chicken broth to thin the sauce.
What serving size is the nutritional info based on? About a cup? I’m trying to log it into my app but we didn’t split it up by the servings amount when we made it.
I have not measured it by cups. Sorry! I just eye up the servings.
I made this recipe for the first time last night. We absolutely LOVED it!!!
The recipe is easy to follow and easy to make!!! This will definitely be one of my “go to” recipes!!!
Do you use deli ham or can I use spiral ham I have left over from Christmas?
Leftover spiral ham works great!
Is it possible to make and place in fridge over night, and pop it in the oven the next day after work?
Yes. Enjoy!
Made it just as is – my sauce wasn’t “saucy” but I put it in clumps all over knowing it would melt/spread. Used Costco shredded rotisserie chicken. Did broiler at the end. So easy – comforting and delicious. Thank you
Yes, this is a thick sauce. Using rotisserie chicken is a great time saver! Thanks for that tip.
I never leave comments, but this casserole is absolutely delicious! We ate the leftovers tonight, and if anything it was even more delicious. This may become a weekly dish at our house! My husband is not on Keto, but he loved it, too. I know I will use the sauce on other dishes as well.
Thank you for leaving your comment! I’m so glad you both liked it 😀
I have high cholesterol, and am diabetic. Is there anything you can suggest to reduce the fat and cholesterol? I’m struggling with this diagnosis (3 weeks), and could just cry. I can’t find any recipes that fit this new lifestyle
I’m so sorry Sharon. I am definitely not an expert in this. Have you looked into Trim Healthy Mama? That balances having low fat (healthy carb) and high-fat meals.
May I suggest checking out what Dr Bill Cole has to say about diabetes, cholesterol and inflammation? There is hope but you won’t likely hear the truth from a conventional MD.
