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.

A friend told me about this website and this is the first recipe I have tried. It was delicious and I can’t wait to try more. I have a slight lactose intolerance so I substituted Kite Hill cream cheese and Violife Mozzarella Shreds. This was so easy to make and so tasty!
Was a great supper the other night. But in the future I will add more cheese. And maybe a Parmesan or mozzarella cheese as well.
Served a group of 15 ladies this and it was devoured. They loved it!!!
My absolute favorite recipe and bonus, my kids and husband love it too! We’ve loved every recipe we’ve tried from this site, but the chicken cordon bleu is definitely one for the weekly/monthly rotation.
Looks delicious. Does it freeze well, before or after baking. I love to cook several days a wee , freezing food to heat up later
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.
This is a family favorite! Everyone loves it!
Great easy recipe that all my family (kids included) loved!!
I made this recipe in the Crockpot. Cooked my chicken in the crockpot, then just added the rest of the ingredients. It turned out great! My family of 4 loves it and it’s always a crowd pleaser when I take it somewhere.
My whole family loves this dish! I’ve made it many times but I use provolone instead of the Swiss.
Has anyone tried using this sauce with shrimp?
That’s a great idea! I haven’t tried it but maybe someone else will answer who has.
I made this tonight using boneless skinless chicken thighs and it was absolutely amazing.
Delicious!
This recipe is simply delicious! I made it for my family this evening and they absolutely loved it. My husband especially kept saying how much he loved it. The combo of tender chicken with salty ham, slightly tangy cream sauce, and gooey cheese made for an outstanding dish. And it was easy to put together – I just baked chicken tenderloins at 400deg for 20min, drained the juices, and added the ham, sauce, and cheese. It was in the over so quickly. This will be in my regular rotation going forward. Thank you for making such delicious recipes, dear friend!
Thank you for sharing!
What’s the serving size for this?
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.
Delicious recipe! Tastes just like chicken cordon bleu. I made it today and my husband and I had it for dinner. We both enjoyed it. Will definitely be making this again and again. I didn’t have Swiss cheese but I sprinkled shredded Colby Jack on top. Turned out great!
