This chicken cordon bleu casserole is easy, rich, and delicious! Layers of chicken, ham, and a savory cheese sauce are topped with buttery Panko breadcrumbs, then baked in the oven until warm and bubbly. This recipe is a much simpler, yet just as comforting and satisfying version of traditional chicken cordon bleu.

What Makes This Recipe So Good

How incredibly easy it is to make! Add shredded chicken to a casserole dish, then top it with ham, a simple cheese sauce and some Panko breadcrumbs. Just 10 minutes of prep is all you’ll need to throw this dish together, then your oven will take it from there!
The cheese sauce alone is deliciously rich and savory. Seriously, you’ll want to add this cheese sauce to everything! The combination of Monterey jack cheese and Swiss cheese create a super flavorful and tangy sauce.
The Panko breadcrumbs create the perfect buttery, crunchy topping to this chicken cordon bleu casserole. The inside is smooth and creamy, so the breadcrumb topping rounds out the textures of this dish. However, you can easily leave out the Panko breadcrumbs if you’d like!

Key Ingredients

Shredded Chicken – I used this method to create shredded chicken for my casserole. Though you can use whatever method you’d like. You can even buy pre-cooked and shredded chicken from the store if you’d like, making this casserole even easier to make!

Cubed Ham – This is the perfect recipe to use any leftover ham you have from Easter! If you plan on buying ham for this recipe, I recommend purchasing a fully cooked, boneless ham. This will make chopping the ham much easier.

Panko Breadcrumbs – Panko breadcrumbs are light, airy, and toast up beautifully. They create a nice golden brown topping on this chicken cordon bleu casserole. Feel free to use regular breadcrumbs instead of the Panko breadcrumbs, you can also leave the breadcrumbs out altogether.

Chef’s Tips

Separate your butter into two tablespoon-sections before getting started with this recipe. The reason for this is we use the butter in two different places in this recipe. You will use the first two tablespoons to make your cheese sauce, and then the remaining two tablespoons to add to your breadcrumbs.
If when the chicken cordon bleu casserole is done cooking, the topping isn’t as golden brown as you’d like it – turn your oven on broil for a couple of minutes. Though if you choose to do this, keep a very close eye on your casserole since it can burn quickly!
To reheat this chicken cordon bleu casserole, place it in a preheated 350° Fahrenheit oven for 5-10 minutes. Reheating in the oven will ensure that the breadcrumb topping remains crispy. You can even prep this casserole ahead of time, cover it with plastic wrap and store it in the fridge for up to 24 hours before baking.
