Although I’ve never really served traditional chicken cordon bleu to my family, I’ve enjoyed it at restaurants and had many variations of the classic like slow cooker chicken cordon blue, cordon bleu sandwich and cordon bleu soup.

This easy chicken cordon bleu casserole is going to be a favorite in your home. It’s reimagined for less effort! There are no “cream of” soups, but a homemade cordon bleu sauce made from butter, flour, whole milk and swiss cheese.

If you want to make it an “all in one” casserole, stir in some broccoli, peas, asparagus or your favorite mixed vegetables.

Ingredients

Chicken. The easiest way to make this chicken cordon bleu casserole is to use rotisserie chicken. You could also use leftover shredded chicken breasts or even leftover chicken tenders.
Ham. This is a great way to use up leftover ham from your Christmas ham, but try using a smoky Black Forest ham or even prosciutto for a more gourmet feel. Love leftover ham recipes? Try our ham pot pie or slow cooker ham and beans.
Cheese. If you want an extra cheesy casserole, add an extra cup of cheese into the base. You can add extra Swiss or try Gruyere cheese, provolone or mozzarella for a creamy blend.
Egg noodles. Use medium sized egg noodles for this recipe. Smaller noodles work better because it doesn’t turn into a noodle dish with extra toppings. Any small sized pasta will work great.
Nutmeg. This is one of our secret ingredient for savory dinners like lasagna, swedish meatballs, ham and cheese croissant bake, chicken stroganoff, slow cooker chicken gnocchi soup and chicken a la king. It adds a hint of warmth and depth.
