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 is the serving size? Thanks!
There are 8 servings (listed near the times). I just eye it up. The easiest way to figure out an exact serving is to weigh your casserole dish before and after and then divide the weight by 8.
Wish you had put the doubled sauce suggestion at the beginning .
Also to make ahead, do I cook completely and then reheat to serve later?
I have never doubled the sauce myself. That is a lot of butter and a lot of cream cheese. I’ve found 1x the sauce to be fine.
You can prep the entire dish up to 2 days ahead and then bake when ready to serve.
will this turn out okay if cream cheese is not used?
You need to sub something else in the sauce. Ricotta cheese, sour cream, another soft cheese, a combo of those. Otherwise the sauce is just butter.
Thank you so much! I didn’t have cream cheese and I can’t get to your recipe through Pinterest anymore. I LOVE this recipe and have been using it for years! Thank you so much
I made this as directed, but doubled the sance. Served over noodles. This dish is so good! Will be making this often. Easy and very flavorful.
Can i add instant white rice to this?
You would have to add liquid too, I think. Otherwise it might not cook.
Very good!!! Easy too!! The only issue I had is that the sauce needs to be doubled. My chicken was very moist, but sauce is soaked up ! Great leftovers too!!
This is absolutely delicious! I drizzled about a 1/4 cup chicken broth on top prior to baking. Then I sprinkled finely chopped scallions on top when done. Had it with fresh roasted green beans. Thank you for such a flavorful recipe!
Absolutely delicious 😋 I’ve made this several times and everytime my whole family gobbles it up.
Yumola!!!!
Delicious! I served with homemade mashed potatoes and corn. followed recipe exactly, whole family loved it .
I made this for my boyfriend who is on Keto. It is an absolutely delicious casserole. I can’t keto due to being too skinny, so I’m going to try and formulate a recipe with some kind of carb added. Maybe some buttery bread crumbs on top?
I would recommend to everyone to add in the wine, it kicks this recipe to the next level!
Thank you so much for this awesome recipe!
For yourself, you could always serve on a bed of egg noodles. And then for your boyfriend this keto pasta is great.
Love love love!
Thank you for putting the nutrition information on there. But how much is a serving I couldn’t find it?
I made it exactly as listed and it came out looking the same as the photos. The chicken was juicy but the casserole lacked flavor. It needs more of something – dijon, black pepper – something! I served it to three people and no one liked it. We tossed the rest. I’m not sure it’s worth tweaking in a second attempt. Just my experience…..
This does have a full tablespoon of dijon mustard in it. Are you sure you followed this recipe?
My didn’t turn out nearly as cheesy and was much drier than pictured. Discovered I forgot the butter. Oh man!! And I think the pre-shredded Swiss cheese was drier as well. Trying to figure out if I can add melted butter to it as I reheat leftovers.
Pin button doesn’t work
My tech support fixed that this morning. Sorry for the inconvenience.
This was so wicked good! I used a rotisserie chicken and it was perfect. It was rich and so hard to stop eating. Thank you for something different with all of my favorite flavors!
My fam loves this!
