Chicken Cordon Bleu Casserole Recipe

The foundation for this Chicken Cordon Bleu Casserole recipe is the traditional Chicken Cordon Bleu dish, which is essentially a chicken breast, pounded thin, stuffed with a slice of ham and a slice of Swiss cheese. It can be baked or fried and then is typically smothered in a  creamy sauce.  Here we take all of that and put in the comfort and ease of a casserole.  Who doesn’t love a good casserole?!    I mean, you can make them ahead of time and pop them in the oven when you are ready.  They are usually easy to convert to a slow cooker meal, and they are perfect for feeding a hungry family!

How to Make Chicken Cordon Bleu Casserole

To make Chicken Cordon Bleu Casserole, start with greasing a 9×13 pan.  Then begin with your layers:

  • 1/3 of the chicken
  • 1/2 of the ham (we used leftover Honey Baked Ham)
  • 1/4 of the Swiss cheese
  • 1/4 of the Monterrey Jack cheese

Repeat this again, and then end with a final layer of chicken.  You can set that aside while you move onto the topping and the cheese sauce.

Panko Crust

I like to start by melting the butter and mixing in the panko.  I do this first and set it aside to give the butter time to fully incorporate into the panko. This will give you a crispier crust at the end.  Feel free to double this portion if you want a thicker crust.

Chicken Cordon Bleu Cheese Sauce

For the cheese sauce, melt the butter in a small saucepan and then add flour and cook for 2-3 minutes.  You are basically making a roux, which is the thickening agent in the sauce.  Add in the milk, broth, mustard, and cayenne pepper and whisk until it starts to thicken.  Side note:  this dish tends to be a little on the spicy side, so cut that in half if you are sensitive to heat.  Next, take the saucepan off the heat and add in a half cup of the Swiss and Monterrey cheeses and also the salt and pepper.  Stir to combine the whole thing and to melt all of the cheese.

Finally, pour this over the prepared casserole, top with any remaining cheese and end with the panko mix.  Pop that in the oven and bake until the top is browned and the casserole is bubbling about 25 to 30 minutes.

What to Serve With Chicken Cordon Bleu Casserole

When it comes to casseroles like this recipe, you will probably want a few side options.  Chicken is filling but I tend to always want a little something extra to pair with it.  These options are always winners in my book!  Most of them are super easy and a great way to add extra vegetables to the table!
