Chicken Cordon Bleu Casserole
If you are looking for a much easier, but still classically-flavored chicken cordon bleu recipe than this casserole is the recipe for you!
I’m not really a casserole lover, I must admit (do you still love me??). Something about all those ingredients trapped together makes me uncomfortable, especially in light of the fact that “open and dump” casseroles just aren’t my thing, really.
But I have had success with a few other wonderful casseroles in my lifetime and this chicken cordon bleu concoction ranks right up there.
In fact, it just might take the casserole cake for deliciousness.
Tender potatoes coated in a creamy, rich cheese sauce are layered in a dish and topped with chicken and ham.
All of these lovely ingredients are covered in the same silky sauce and topped with a buttery bread crumb crust.
The casserole is baked until bubbly and golden and the result is such a wonderful combination of flavors that it made me realize I can put off conquering “real” chicken cordon bleu for a while and enjoy this instead.
A perfect dish to take-in to someone, equally perfect for a potluck, and it made wonderful leftovers. Personally, I had to tie my arms to my chair in order to resist going back for thirds.

Chicken Cordon Bleu Casserole
Ingredients
Topping:
- 4 slices white sandwich bread, torn into quarters
- 2 tablespoons butter, melted
Filling:
- 3 pounds russet potatoes, about 4-5 medium, peeled and sliced 1/8-inch thick
- 1 teaspoon salt
- 4 tablespoons butter
- 1 medium onion, chopped
- 1 teaspoon dried thyme
- 3 medium garlic cloves, finely minced
- 6 tablespoons all-purpose flour
- 2 cups low-sodium chicken broth
- ¾ cup heavy cream or milk
- 6 ounces Swiss cheese, shredded, about 2 cups
- 2 tablespoons Dijon mustard
- ¼ teaspoon cayenne pepper
- 2 pounds boneless skinless chicken breasts, trimmed of excess fat and sliced thinly
- 9 ounces deli ham, chopped
- 2 tablespoons minced fresh parsley leaves
Instructions
- For the topping, process the bread and butter in a food processor until coarsely ground. Set aside.
- For the filling, preheat the oven to 400 degrees, making sure the oven rack is in the middle. Place the potatoes, 6 cups water and 1 teaspoon salt in a large pot.
- Bring to a boil over high heat, then reduce the heat to a simmer and cook, uncovered, until the potatoes are partially cooked, about 2 minutes (don’t overcook because they will continue to cook in the oven!). Carefully drain potatoes, or remove them with a slotted spoon, and transfer them to a bowl. Set aside.
- Meanwhile, melt the butter in a medium saucepan over medium heat. Add the onion, thyme, and 1/2 teaspoon salt. Cook until the onions are softened, about 6 minutes. Add the garlic and cook until fragrant, stirring constantly, about 1 minute. Add the flour and cook, stirring constantly, until golden, about 1 minute (this helps cook out the flour taste in the roux). Slowly whisk in the chicken broth and the cream or milk. Bring the mixture to a simmer, whisking often, until slightly thickened (if using milk instead of cream, you may have to cook longer for it to thicken up a bit).
- Off the heat, whisk in the Swiss cheese, Dijon, and cayenne pepper until smooth. Season with salt and pepper to taste. Cover and set aside until ready to use.
- Toss the potatoes with half of the sauce and spread into the bottom of a lightly greased 9X13-inch baking pan. Layer alternating pieces of the chicken and ham over the potatoes, overlapping as needed. This is not a scientific procedure, just make sure that the chicken is in a single layer (not on top of each other) so that it cooks thoroughly. Pour the remaining sauce evenly over the chicken and sprinkle with the bread crumb topping.
- Bake until the chicken is cooked through and the casserole is bubbling, 30 to 35 minutes (add about 5-7 additional minutes onto the baking time if baking it after it has chilled in the refrigerator for more than a couple of hours). Sprinkle with parsley and cool for 10 minutes before serving.

We didn’t like this and our potatoes were not cooked enough. Sorry. But there have been so many over the years that we have loved and cook all the time. Chicken pot pie with biscuits, enchiladas casserole, gyro etc
I want to call BS on the 20 minute prep time. Very frustrated.
What’s the cooktime difference if I use yukon golds instead of russets? thanks!
It should be about the same.
I made this tonight for the first time and it was a big hit with my entire family of five. My husband normally hates casseroles and he said it was delicious and would ask for it again. Thanks for such a yummy recipe!!
Another dinner hit!
Don’t think our 4 year old or or 2 year old came up for air!
Have made this several times and it is absolutely Fabulous!!
It freezes really well. Just let cool completely in the fridge, cut into bricks,
wrap with foil and stick in a bag. Re heat at 350 degrees right out of the freezer for
60 minutes.
Today cheese, chicken and potatoes were on sale. Calculated the cost per meal (serving 8) is $1.42!! Wow! This recipe wins in so many ways. Thank You for sharing.
I was very skeptical indeed, but I am a believer!
Turned out so yummy even though I forgot to add the garlic.
The topping was the best part, but I did add some garlic powder and salt after tasting a bite. The white bread method will be my go-to from now on when it comes to crispy toppings!
I made this for dinner tonight . I split this into 2 8×8 square casserole dishes. My husband and I had one casserole and I took the other one to my mom who is undergoing chemo. This casserole was a big hit! I really liked the subtle kick from the dijon mustard. Thanks for another stellar recipe.
I finally made this recipe tonight and it was so delicious. It took some time to prepare, but it was really worth the effort. It was a big hit with the family so I plan to make it again and again. The only change I made was that I substituted panko crumbs for the fresh bread crumbs.
Hi Mel. I am trying to figure out how you made this ahead. Did you assemble it all the night before and then bake it the next day? Or, did you bake it, store it baked in the refrigerator, and then just heated it up?
I want take this to a friend who just had a baby. I want to make it as easy as possible for her and do not want her to do much work besides sticking it in the oven.
Sara – I assembled it and refrigerated – then baked the next day.
Delicious! I even subbed rice milk and brown rice flour and my kids wanted to drink the sauce it was that good. Thanks for always sharing awesome recipes that are family friendly Mel. I’m always coming to your site first when trying to come up with recipes. (Love the giant cookie recipe for gifts!) Thank you so much.
Mel – This dish made me look like a rockstar. I did two batches in one day; one for a mom who just had her fifth baby and one for us and our guests that evening.
Empty plates. Practically licked clean. And the mom said that her I-like-what-I-like-and-not-much-else husband loved it. He even went out of his way to tell me so.
THANK YOU. You’ve saved my day yet again.
First i must say that im your new biggest fan! I ade 3 recipes from your blog this week- ALL amazing!!!
This may be a stupid question but the chicken/ham, do you place the ham on top of the chicken layer?
Anne-Marie – I just alternate the ham and chicken so it’s all mixed in together (in a single layer). Does that make sense?
Hi Mel. I want to make this for friends at my annual Christmas party and I want to assemble it in the morning before serving it that night. I plan to use shredded rotisserie chicken already cooked- will that be okay? Also can I assemble the entire casserole and put it in the refrigerator for at least 9 hours and then allow an extra 15 minutes in the oven ? Thank you!!!!
Kathryn – I think the already cooked chicken should be ok – I worry a little that it might get dried out since the original recipe calls for uncooked chicken but hopefully it will be ok. I think you could definitely assemble ahead of time – the only risk you might run is the potatoes browning before baking. Good luck!
Made this last week and it was delicious!! Very creamy comfort food. Loved the potatoes and using my food processor to cut them made preparation simple. Loved the little crunch of the breadcrumbs on top too. So good:) everyone agrees to add it into our meal rotation
I’ve been a fan forever of your site and wanted to let you know how I made this meal gluten free. I am uber sick pregnant and was craving a casserole of all things and was beside myself trying to find something that didn’t have rice (being gf, you eat a ton of rice) and that I could adapt. This won on all accounts. I used about 3 large tbs of cornstarch to thicken rather than the flour and then took your advice and found an old gf bagel in the freezer that my gf daughter didn’t like and used it for the bread topping. My kids, who are good eaters but don’t love potatoes, loved this meal. I also used bacon instead of ham since it was all I had but no real change with that. My favorite – the cayenne. I love me some heat and next time, I’ll add a pinch more. Mmm, mmm good!
Hi Mel~I am serving this for dinner tonight. I have made it before and we loved it. As I was making this, I was thinking….I wonder what Mel uses for chicken broth? Do you buy a specific brand or make your own? Just curious since you are my go-to food blog!! Thanks for doing a great job!
Hi Katrina – I don’t always have homemade chicken stock in the freezer. When I do, I use it, but if not, my go-to is Swanson’s Natural Goodness 33% Less Sodium. Love it and use it like crazy.
I just made this for dinner tonight. The kids are going crazy over it. This will definitely be served at our table over and over again. Thanks for the great recipe!
We made this tonight and everyone said it was a “keeper”. Thanks for getting me out of my dinner doldrums! I downloaded a couple of other recipes this weekend to use in the coming nights.
Anna – after all these comments and I think you are the first to notice the parsley error! Thanks for the heads up – I sprinkle it on top after the casserole has finished baking. Glad you liked the recipe!
Thank you for this awesome recipe. It was absolutely worth all the trouble translating the american units into european units 🙂 I just have one (silly) question, what do you do with the parsley?
Thank you for a recipe that does not contain “cream of anything” soup. Can’t wait to try this.
Does this bake uncovered?
Julie – yes, this bakes uncovered.
Mel, I made this and both my husband and I loved it! I left out the cayenne pepper and it was still amazing! I have also made your Chicken Cordon Bleu (which was SO good BTW!) and really liked the bread crumbs on that much better than the ones in the casserole recipe. Just curious if you could substitute that for the topping in this recipe instead.
Thanks for sharing your recipes! I have yet to find one that we don’t like!
I made this the other night and substituted brown rice for the potatoes because I wanted to freeze half of it. It still tasted great!!
Working through your recipes, so just had to try this one the other day! It was wonderful! I had a little bit of trouble with baking time, ended up keeping it in the oven for extra 20 minutes, I must have either cut potatoes too big or did not boil them enough, but the end result was amazing. Very comforting meal: left overs were even better! To the next recipe to try for lunch! Keep them coming girl!
Hi Mel,
I had some extra deli ham I needed to use up at the school. So I made this recipe leaving out the cayenne. Of course I had to adapt the recipe to feed 60 but was easy to do . Instead of potatoes (I didnt want to peel that many) I used egg noodles and it married very well with the chiken, ham an sauce. Just cooked them halfway and they were perfect. Using the noodles also counted as the bread component so I killed two birds with one stone. Love this website. I also do all the in house catering for the agency I work for, will definitely be adding this to my catering menu.
Thanks,
Teresa
I was very careful to follow the directions when I prepared this amazing sounding casserole. It smelled wonderful and looked beautiful at the end of the cooking time. Unfortunately, when we sat down to eat it, the chicken was still raw. Was I incorrect in assuming thinly sliced raw chicken was to be used in the recipe?
Hi Linda – you are correct, the chicken is uncooked when assembled in the casserole. I’m sorry it didn’t cook well for you. I don’t know why it would be different – I have made this countless times and the chicken has cooked through. I’m sorry!
I made this today and it was a BIG hit with my family – even with my “hotdog and nuggets ONLY” 3yr old. I LOVE the sauce – it’s incredible. And slicing the chicken breast really thin and placing it on top like that baked up so tender. YUM! Thanks!
I made this last week for me and the hubby. I accidentally put honey mustard in the sauce rather than the dijon–the bottles were the same color in the fridge! It was still fantastic! Since it is just the two of us I decided to freeze half and see what happened. I was worried that the texture of the potatoes would be nasty, but it was just as good as the first night! Thanks for sharing. I love gawking over other food blogs too, but when I’m looking for something to actually make, I come straight here. I always seem to have the ingredients around that you use in your recipes. I’ve been a faithful follower/stalker of your blog for over 2 years now! Not sure what I’d do without you–you’re the greatest!
I have read your blog for a while now, but this is the first time I have ever left a comment. I never really do. But I had to tonight because a miracle happened at our house. My 6 year old and my 3 year old, who have to be the most pickiest eaters ever, asked for seconds!! Believe me when I say that that never happens. I was delicious, just like all the other yummy dishes I have made from your site. Thanks for helping me get my little ones, who could best Ghandi in a hunger strike, to eat and ask for more. 🙂
I have made this a few times, everyone loves it, but tonight I wanted to use up some of the NYE nibbles so used the leftovers from the cheese board instead of Swiss (a very stinky Danish Blue, Red Leicester with caramelised onions, and a sharp White Cheddar.) Also I chopped up a little summer sausage instead of ham. It was still really yummy and it’s nice to see the fridge with a little more space. Thanks Mel, for yet another fab recipe!
Annette – your cheese selections for this dish sound fantastic! I love the possibilities this could open up. Thanks for checking in…
Just tried this recipe out for a football gathering. 12 picky, full-grown men agree… delicious! I’ve had two generous helpings and I still want more. Wow. Thanks!
Darcy – that’s the real test…and if 12 picky adults liked it, then I’d say it was a success! Thanks for letting me know!
Mel,
I really want to make this for a meal swap….and I understand the concern with the potatoes and freezing…..what do you think if I used frozen hashbrown in place of the fresh potatoes? Love that I can make it GF easily too!
Joey – I think using frozen hash browns is actually a great idea. Let me know if you try it!
I love this!!! Made it for the 2nd time tonight & even made a pan for a friend that just had a baby. THANK YOU. Love your recipes!!
Becky – thanks for your comment! This is a great take-in meal option…hope your friend liked it!
