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.

oh my. this was fantastic! my family loved it. recipe printed and add to my regulars. Thanks!!
I just don’t what the serving size is. Most of these keto recipes don’t list it. So is it a cup? That’s what I’m assuming.
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.
Its in the oven now…I par roasted the chicken tenderloins……Ill let the oven finish them…and cut them into pieces….looks delish..so far….I can’t wait!! Lolol Great recipe!!
Have you tried adding par-cooked cauliflower to add fiber? I have a recipe for ham and cauliflower casserole that is similar to this recipe
Yup, cauliflower and/or broccoli are great in this! Or cauli-rice.
Halved everything except the sauce because there are only 3 of us. My super picky 12 year old even liked it which makes it a keeper in its own!
Delicious. It’s so much easier than Chicken Cordon Bleu. I’m saving this on Pinterest.
Does this freeze well?
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.
The recipe for Chicken Cordon Bleu Casserole sounds yummy & easier than rolling in ham. I am lactose intolerant , is the something I can substitute for the cream cheese? I can hard hard aged cheese like aged swiss, which I love but no cream cheese, cottage cheese or anything like that. Wonder how greek yogurt would be?
I use a combination of coconut cream and mayo in my dairy-free chicken zucchini casserole: https://joyfilledeats.com/chicken-zucchini-casserole/
A combo of mayo and yogurt could work too.
Sorry for all bad typos, recent eye surgery and not doing well…need to proofread first. 🙂
Net carbs????
It’s in the recipe card. This has 0 fiber so total carbs and net are the same. 2 carbs per serving. There are 8 servings.
I’m so excited to try this recipe! I have a question though! Can I assemble this the night before, and cook it the next day?
Yes. I hope you enjoy it!
This was delicious! My whole family loved it, but my VERY picky 12-year-old son loved it SO much that he had THREE SERVINGS!! I have a hard enough time getting him to eat one serving at dinnertime, so I was blown away!! This is definitely a recipe I will be making again – thank you!!
I’ve made it twice now, and my family really enjoys it! Thanks for the recipe!
Love this recipe. Made it several times 😋
This looks amazing but several don’t like swiss cheese. Any other cheese suggestions?
Cant wait to try!!!
Have you tried baby swiss? It is very mild. Mild provolone and mozzarella work well too.
This recipe is a keeper! I am so happy I found it this evening. I just happened to have left over sliced ham and swiss cheese from sandwiches last week.
So I did improvise a little as I only had one large chicken breast….
I pounded, seasoned (with olive oil, salt, pepper, garlic powder, onion powder , and chile) , and baked one large chicken breast at 450 for 17 mins then drained the juices and sliced the chicken into pieces.
I then immediately layered the ham, the cream cheese mixture (used only 4 oz cream cheese and 2 oz butter) , and cheese on the hot chicken and put in oven for 30 mins then broiled for 2 mins. It was perfection!! I will seriously be making this for years to come. Never making chicken cordon bleu any other way as casseroles are just the way to go!
I so want to make this for my family, have you ever used a rotisserie chicken in this dish? Do you think it would work with flavors? Thanks for sharing this amazing recipe!
Yes, you can use rotisserie chicken. I also use chicken tenderloins a lot and don’t shred them. I just drain the cooking liquid and then add the sauce and toppings.
