Chicken Cordon Bleu Casserole

This chicken cordon bleu casserole has all of the flavors of the classic dish in a delicious casserole. Tender chicken and ham are topped with a creamy sauce and buttery bread crumbs. This easy weeknight dinner is always a hit with the whole family!

I have always loved chicken cordon bleu but stuffing and breading chicken is a bit labor intensive for a busy mom. That is why I love this recipe, it has the delicious traditional chicken cordon bleu flavors of salty ham, juicy chicken, swiss cheese and a creamy dijon sauce, and buttery breadcrumbs in casserole form.

This recipe is a great way to use up leftover ham or leftover chicken. This delicious recipe comes together easily so it is a great weeknight meal but it is also tasty enough to serve to guests or at a family dinner.

Simplify making this casserole– This casserole is perfect for busy weeknights especially if you follow these easy tips. If I am making chicken or ham for another recipe I like to cook extra to have on hand for this casserole. You can also use a rotisserie chicken so that you don’t have to cook chicken. Or put your chicken breasts in a slow cooker so that they are cooked and ready to go when you are ready to assemble the casserole for dinner.

What to serve with this casserole- I like to pair this casserole with an easy side dish to keep dinner simple. I usually serve it with a simple roasted or steamed green veggie like green beans or broccoli. Another great option is a simple side salad. You can also serve it over something like rice or egg noodles for a complete and hearty dish.

Make this casserole low carb– This casserole is full of fat and protein which makes it a great option for anyone following a keto or low carb diet. Simple swap the panko breadcrumbs for ground pork rinds, use heavy cream in place of the milk, and you’ll have a keto chicken cordon bleu casserole that is low carb and full of flavor!

How to store this casserole- Store leftovers refrigerated in an airtight container. You can also wrap the casserole in plastic wrap or foil to store it.
