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.

    Would soday crackers work instead of panko instead of pankombread crumbsL i have all the other ingredients.

    1. Kristyn Merkley says:

      Yes, I am sure they would 🙂

    *I love the concept of this recipe, but next time, I will not use Honey Ham…its too sweet of a casserole for me.
    *I also think the ham I used made it watery when the water cooked out of the ham…I may pre-cook the ham next time.
    *45 mins. bake time made the already cooked chicken mushy…maybe just 20 mins.
    *I think I would make less sauce, OR, layer some on the chicken, some on the ham and then bake it without the crumbs as they too were mushy in places…maybe put the crumbs on during the last 10 mins.

    This looks so good, but i only have swiss cheese that i would need to grate. Do you have any idean how much that would be? Thanks.

    1. Kristyn Merkley says:

      I would guess around a cup of grated cheese. You can’t go wrong..if you like cheese, add more & you can always add less. Hope that helps! Enjoy!

    I have made this before and it’s great but I served noodles on the side. I like the idea of noodles in the bottom only should they be cooked or raw?

    1. Kristyn Merkley says:

      I haven’t tried adding noodles, but I would maybe cook them. Hope that helps! ENJOY!

  5. Di says:

    How many carbs and caloriess

    1. Kristyn Merkley says:

      I am sorry, I do not have those numbers. There are sites where you can convert your recipe, to see.

  6. Carolyn Lingerfelt says:

    1. Kristyn Merkley says:

  7. Pat Shannon says:

    Thank you. How nice a prompt reply.

    1. Kristyn Merkley says:

      You are so welcome!

  8. Pat Shannon says:

    I’d also like to know if that is the correct amount of butter 8tbsp? Please answer thank you

    1. Kristyn Merkley says:

      Yes, 8 T. 🙂 Hope you like it!

  9. Janet says:

    Could you add noodles to this to stretch the number of servings? Or maybe rice? I’m thinking this would be great for a family get together but could be a little expensive for our large family.

    1. Lil' Luna says:

      Of course!! Whichever you prefer, would be great! Enjoy!!

  10. Andrea says:

    Recipe on tasty kitchen calls for half the butter (4 tbsp) as opposed to your 8 tbsp. Is that a misprint or is it actually that much butter? I just made it and it seemed like a lot of butter so wanted to double check. Thanks!
