Everyone Loves a Casserole

Are you scouring Pinterest for dinner ideas for the week? If so, look no further! I have another great casserole dish, that I think you’re going to like. And surprisingly, it doesn’t call for cream of chicken. 🙂

Instead, this Chicken Cordon Bleu Casserole calls for yummy ingredients like ham, Swiss cheese, freshly squeezed lemon juice, Dijon mustard, and is topped with crunchy Panko crumbs.

This recipe was a big hit with the adults AND the kids, which always makes for a perfect, new, go-to recipe that makes life easier! You guys know that we are all about easy dinner recipes, and we really think you’ll love this one. It’s obviously a take on Chicken Cordon Bleu but in a casserole form and since everyone loves casserole, we know you’ll love this dish.

Layers of chicken and ham for chicken cordon bleu bake

Simple layers

With so many delicious layers, this casserole is so flavorful and still simple.

MEAT & CHEESE. Begin by spreading the shredded chicken onto the bottom of a greased 9×13 dish. Scatter chopped ham over the top of the chicken. Lay Swiss cheese slices on top of the ham, and then make your sauce mixture.

SAUCE. This is made by melting butter in a pot, and then adding flour to create a roux. Once smooth, whisk milk in until the sauce thickens. Add lemon juice, dijon mustard, salt, smoked paprika and white pepper. Bring to a boil and then remove from heat. Pour the sauce over the top of the casserole.

TOP & BAKE. Top with buttered Panko crumbs and parsley, if desired. Bake for about 45 minutes or until hot and bubbly. Let rest for 10 minutes before serving.

Slow Cooker Version

Absolutely! Follow the directions as written in the recipe except you’ll put it in a slow cooker instead of a baking dish. Cover and cook on high for 2-3 hours or low for 3-4 hours. When the casserole is about finished preheat the oven to 350 degrees F.

In a separate bowl  mix the topping ingredients, pour onto a baking sheet and bake the topping for 10-15 minutes or until lightly browned and crisp. Sprinkle the topping over the casserole.


  • Add green veggies such as broccoli florets or peas
  • Substitute swiss cheese with another of your favorite cheese such as, cheddar, gauda, pepper jack or mozzarella.
  • Replace breadcrumbs with stuffing mix
  • Serve over or next to cooked noodles, rice, or mashed potatoes.

Storage Tips

Can I freeze cordon bleu casserole? Prepare casserole according to recipe instructions except for the bread crumbs. Wrap dish with plastic wrap then again with aluminum foil. Label and freeze for up to 3 months. Thaw overnight. Add bread crumb topping and hake according to recipe instructions.

How to store and reheat leftovers: Discard if the casserole has been sitting out for longer than 2 hours. Otherwise store leftovers in an airtight container in the fridge for 3-4 days. Use a baking dish to reheat in the oven. If you’re in a hurry you can also reheat in the microwave.

    My family loves this casserole! I’ve made a version in the past that was just cream of chicken soup layered on top of the chicken and ham, under the swiss cheese and stuffing, so I felt like this sauce really elevated it. I love that you give the info about freezing and even have a slow cooker variation! I can’t wait to try it!
