Chicken Cordon Bleu Casserole
This Chicken Cordon Bleu Casserole has been a reader favorite for years, earning hundreds of 5-star reviews for its creamy sauce and perfect keto-friendly topping. This easy chicken casserole delivers all the classic flavors of ham-wrapped chicken without the tedious rolling and breading.
I love chicken cordon bleu. After trying an incredible chicken cordon bleu at a fundraiser years ago, I knew I wanted to turn those flavors into an easy casserole. With chicken, ham, and Swiss cheese in a creamy Dijon sauce, you won’t miss the breading one bit. Since you aren’t coating or stuffing the chicken, it is quick and easy.
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 everyone cleaned their plates.
Why you’ll love this recipe:
- Quick Prep: No rolling or stuffing required.
- Family Friendly: Even non-keto eaters crave this sauce.
- Meal Prep Ready: Tastes even better as leftovers the next day.
Tips for the Best Cordon Bleu Casserole
- The Chicken: Rotisserie chicken cuts prep time in half. Or bake chicken tenderloins, drain the liquid, and then use those in this recipe (no shredding required).
- Dry Chicken: One of the most important things for this recipe is to make sure the chicken is nice and juicy. If the chicken is juicy, the casserole will be too. If you are starting with dry chicken, I recommend making 1.5 times the sauce to compensate. Or even doubling it.
- The Sauce: If the sauce is too thick, whisk in a tablespoon of heavy cream until smooth.
- Cheese: I’ve had readers substitute in other mild cheeses like provolone, mozzarella, or Havarti, so feel free to tailor this to your family’s tastes.
- The Topping: For that signature crunch without the carbs, I recommend crushed pork rinds or almond flour mixed with butter and seasoned with garlic salt.
- Preventing Breakage: Make sure your cream cheese is softened to room temperature before mixing to ensure a velvety consistency.
The Best Creamy Keto Sauce for Cordon Bleu
We love this creamy lemon sauce on our Chicken Cordon Bleu Casserole. It is rich with 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 it 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!

Chicken Cordon Bleu Casserole
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!
