We made it….it’s Friday! And even if you have a jam packed weekend scheduled, I hope you’re in a part of the country that’s enjoying some of that mild fall weather I’ve been waiting for.

I just got back from Iowa where we spanned three different seasons in just three days. It’s pretty crazy…..but the last day was absolutely frigid because the wind was blowing pretty fiercely. It made me want to sit down and stuff my face with some serious comfort food!

I’ve been dabbling in casserole recipes again because they were such a staple of my childhood. So simple to throw together, the ultimate casserole is a one hit wonder that’s sure to please even the pickiest eater in your family and this Easy Chicken Cordon Bleu Casserole is no exception.

Made easy with fresh, simple ingredients you can pick up at your local grocery store, this Chicken Cordon Bleu Casserole is a twist on the classic Chicken Cordon Bleu recipe. I absolutely love the contrasting textures and flavors of this dish.

From the crispy, buttery breadcrumb crust to the tangy, buttery cheese sauce, this dish is quick to throw together for an easy weeknight dinner.

What is Chicken Cordon Bleu?

Chicken Cordon Bleu is a french classic chicken dish. It’s, basically, chicken breast that’s been butterflied, then stuffed with ham and Swiss cheese.

Sometimes the chicken is breaded then fried but I’ve also seen it breaded and baked in the oven. The crispy exterior is a great contrast to the cheesy, salty filling. It’s definitely one of my favorite chicken dinners ever.

How do you make Chicken Cordon Bleu Casserole?

This Baked Chicken Cordon Bleu Casserole is a cinch to make. I like to start with roasted chicken. I’ve seen it made with raw chicken that’s been baked in the Chicken Cordon Bleu sauce but the sauce tends to get watered down and it adds a raw poultry flavor that’s not really my favorite thing at all.

This is the perfect way to use up that leftover Sunday roasted chicken or your favorite rotisserie chicken.

  1. First, cut up the chicken into bite sized chunks. (Or you can shred it if you prefer.)
  2. Place the chicken in the bottom of a 13×9 inch baking dish and set aside.
  3. Make the cheese sauce by melting butter in the bottom of a large sauce pan.
  4. Whisk the flour into the cheese sauce and cook for 1-2 minutes.
  5. Add the milk to the flour mixture and whisk to combine.
  6. Stir in the garlic powder, salt, pepper and dijon mustard.
  7. Continue cooking over medium heat until slightly thickened and sauce coats the back of a spoon.
  8. Stir half the shredded cheese into the milk mixture and remove from the heat.
  9. Pour the cheese sauce over the chicken in the baking dish.
  10. Top the chicken with the ham and sprinkle with the remaining shredded cheese.
  11. In a small bowl, toss together the bread crumbs and butter. Stir in the herbs.
  12. Sprinkle the bread crumb mixture over the cheese evenly.
  13. Bake the casserole for 30 minutes until golden brown and bubbling.
  14. Allow the Chicken Cordon Bleu Casserole to rest for 10 minutes before serving.

Can you make Chicken Cordon Bleu Casserole in advance?

YES! You can make this Chicken Cordon Bleu Casserole recipe in advance and reheat it in the oven when ready to serve.

BUT you can also ASSEMBLE the casserole in advance, cover and store in the refrigerator until ready to bake because the chicken is already cooked. I would definitely recommend trying this meal prepping plan to save yourself some weeknight sanity. Just check out the recipe notes for tips on how to do this for best results.

Can you FREEZE Chicken Cordon Bleu Casserole?

Again, YES! Because the chicken is already cooked you can safely freeze the casserole for easy dinners at another time. It’s also fabulous for Pot Lucks.

To freeze:

  • Assemble the Chicken Cordon Bleu Casserole up to the ham topping.
  • Allow to cool to room temperature.
  • Once cooled, top the casserole with the cheese and bread crumb topping.
  • Cover the casserole tightly with plastic wrap and then cover with foil.
  • Label the casserole with the name of the dish “Chicken Cordon Bleu Casserole” and cooking instructions, as well as, the date you froze it.

To cook from frozen:

  • Remove the foil and plastic wrap from the casserole.
  • Preheat the oven to 425 degrees.
  • Bake the casserole for 1 hour or until golden brown and bubbling.

I like to serve Chicken Cordon Bleu Casserole with a side of green beans or a light green salad like this classic wedge. Either option makes for a hearty and comforting week night dinner.
