Chicken Cordon Bleu Casserole is any easy casserole with layers of chicken, ham, a delicious cheese sauce, and topped buttery Panko breadcrumbs. It’s a comforting casserole that’s delicious and a favorite!
This casserole version of your favorite rolled and breaded cordon bleu is so much easier, yet has the exact same flavors.
Chicken cordon bleu is delicious, but let’s be honest, it isn’t very easy to make! So, why not formulate this amazing entree into a super easy casserole? It’s got all the same flavors, and is just as tasty, but is far easier to make. That’s a win in my book!
I love making chicken cordon bleu casserole as an easy dinner during the week. It’s super filling, so I always tend to have leftovers to eat for lunch the next day. I love pairing this easy dinner casserole with mashed potatoes and bacon wrapped green beans. A dinner so full of comfort food!
Why You’ll Love Chicken Cordon Bleu Casserole
- This easy chicken cordon bleu casserole only takes 15 minutes to prep! The rest of the work is done by the oven.
- There is minimal clean-up after making this casserole. Perfect for busy evenings when you don’t have time clean a mess in the kitchen.
- It’s super easy to make, even if you’re not very experienced in the kitchen!
Ingredients needed for this Chicken Cordon Bleu Casserole Recipe
- Shredded Chicken – You can easily make shredded chicken in the Instant Pot or Crock Pot. Or, grab a rotisserie chicken from the grocery store and you can shred that to use in this casserole recipe.
- Milk – I used whole milk in this recipe, but you could use 2% milk or 1% milk if you prefer.
- Sliced Deli Ham – I recommend getting thick cut deli ham! Just get your favorite kind, but you’ll have best results with a high quality deli meat.
- Dijon Mustard – Dijon mustard is that classic chicken cordon bleu taste!
- Shredded Mozzarella – You can buy shredded mozzarella or buy a block to shred yourself. You can also use slices of mozzarella cheese if you’d like!
- Smoked Paprika – Regular paprika will work in a pinch, but smoked paprika really helps bring a lot of flavor into the cheesy sauce
- Panko Breadcrumbs – Be sure you get plain panko crumbs! The bread crumbs with seasonings may taste a little off in this recipe.
- Flour – You’ll need a little dash of all-purpose flour in this recipe.
- Butter – Feel free to use salted or unsalted butter, either will work great.
- Lemon Juice – You can either use fresh squeezed lemon juice or use bottled lemon juice.
- Salt and Pepper – These simple seasonings are perfect for this delicious casserole.

How to Make Chicken Cordon Bleu Casserole
Prep the Casserole
Preheat the oven and lightly butter or spray a 9×13 inch casserole dish and set it aside.
Spread the shredded chicken onto the bottom of the baking dish in an even layer and then sprinkle the chopped ham on top of the chicken. Sprinkle shredded cheese over ham and chicken layers.
Make the White Sauce
In a medium sized saucepan, melt butter over medium heat. Once melted, add the flour and stir until it creates a thick paste.
Once the mixture begins to bubbly, slowly pour in the milk while stirring or whisking to make a smooth sauce. Continue stirring over medium heat until the sauce thickens.
Add the lemon juice, dijon mustard, salt, paprika, and pepper. Bring the sauce to barely a boil and remove from heat.
Pour over the layers of chicken, ham, and cheese.
Top it and Bake it
Melt some butter and then mix in the Panko crumbs. Sprinkle the mixture over the top of the casserole.
Bake for 30-35 minutes and then let cool for 10-15 minutes before serving!
What to serve with Chicken Cordon Bleu Casserole
I always make sure to serve a tasty veggie with chicken and ham recipes like this casserole. These glazed carrots and air fryer broccoli are perfect! This casserole also goes great with smashed potatoes and oven roasted potatoes.
Air fryer asparagus, a side chef salad, and fluffy dinner rolls would all be fabulous sides with this hearty dinner too.

Can I use leftover chicken in chicken cordon bleu casserole?
You definitely can! I wouldn’t recommend using chicken with strong flavors or sauces, but any mildly seasoned chicken can be shredded and used in this casserole.
Is chicken kiev the same as cordon bleu?
Nope! These are two entirely different dishes. Chicken kiev is stuffed with an herb butter, while chicken cordon bleu is stuffed with a ham and cheese mixture. Both are very hearty, comfort food dishes with loads of flavor. And this recipe is a casserole version of the classic chicken cordon bleu.
Pro Tips for the Best Chicken Cordon Bleu Casserole
- Grease or butter your baking dish really well so that your casserole doesn’t stick to the sides.
- If you have leftover honey ham from the holidays, slice it up and use it in this recipe!
- Use some fresh mozzarella along with your slices or shredded mozzarella for some extra cheesy goodness.
Isn’t this just so much easier than regular chicken cordon bleu? And it’s so good! I can’t wait for you to try it.

Joe says
Can you prep this the night before?
Elena says
Very good flavor and super simple. My family loves Cordon Blue but as you said its too involved to make often. This casserole fits the bill.
Tricia says
I was wondering about adding the French onions from the can on top? We get together for pot lucks once a week this would be GREAT to serve!
Courtney says
If you enjoy the french onions then you should definitely add them!
Dee says
What do think of a spin using pre-packaged diced ham? And what can you substitute for the Dijon? TIA
Courtney says
You could use the pre-packaged diced ham! The next best thing you might have on hand is yellow mustard.
Nancy says
Beyond delicious and so easy to make. Another fantastic recipe, Julie! Keep them coming.
Courtney says
Thank you, Nancy! So great to hear you enjoyed this recipe.:)
Annette Kreamer says
I want your Recipe please that look so Good.
Dorothy says
I love this recipe! It doesn’t have to be bland like someone says. Every time I make it I change it up to however I feel for the day! Sometimes I add rosemary, sometimes garlic, whatever I feel like. You can sample the white sauce before you pour it over the other ingredients so it’s just how you want it. Thanks again Julie. I love your recipes! I especially try the smoked ones!
Julie Evink says
So glad to hear this Dorothy! Great tips!
Carolyn says
Quite bland. I doubled the Dijon and used lite swiss (that’s all I could find that day), otherwise I followed the recipe. Too much panko topping, it just makes a mess. I won’t bother with it again.
Julie Evink says
I’m sorry you didn’t enjoy it!
Lawrence Domingos says
I agree with you
Julie says
Thanks!

Gayle Bridges says
Can’t wait to try it.
Julie Evink says
Enjoy!
Judy Gonzalez says
I made this tonight and we really enjoyed it! I didn’t have lemon juice so I used 1 TB white vinegar in the sauce instead (I googled it!)
Julie Evink says
I’m so glad you could make it work for you and that you enjoyed it!
