Try this Creamy Chicken Cordon Bleu Casserole
Chicken cordon bleu is made of thinly pounded chicken breast stuffed with ham and cheese, which is then rolled up, breaded and pan or deep-fried and served with a mustard cream sauce. The casserole version captures all the flavors without the steps.
Southern dinner casseroles don’t have to be boring, with just a few ingredients you can create a simple chicken dinner with all the flavors of a French Bistro. It’s a great way to use up leftover ham or turkey from a holiday meal and create a casserole that everyone, even the kids, will love.
This easy casserole is creamy, filling, and super cozy, it’s comfort food at its best, and who doesn’t love a good casserole?
Start with a rotisserie chicken,(you can roast your own chicken, or use leftover turkey) then add ham, (leftover or from the deli). Since the meat is already cooked, all you have to do is add a cheesy sauce and let it get all bubbly and crispy on top.
There’s no rolling, stuffing or frying in this version. You just layer and pop it in the oven. If you love easy casseroles, try this reader-favorite million dollar chicken casserole next.
Serve this French inspired dish on it’s own, or over egg noodles. Just throw in a light and refreshing salad and you have a dish that takes no time but is nice enough to serve for company. It’s also great with steamed broccoli, the broccoli’s texture is perfect for dipping in extra sauce.
With school back in session, we all need some easy dinners we can throw together. It’s also great as leftovers.

Ingredients You’ll Need
Check the recipe card below for all the details.

- Cooked chicken and cooked ham- Cooked shredded chicken makes up the bulk of the casserole. You can also use leftover turkey. You can use any leftover holiday ham or buy a slab of ham from the deli counter.
- White wine – White wine adds a little acidity. You can skip it if you don’t have an open bottle or use a splash of lemon juice.
- Swiss and parmesan cheese – Swiss cheese is traditional for chicken cordon bleu, and parmesan adds even more flavor.
- Dijon mustard – Dijon mustard is a key flavor in a classic chicken cordon bleu sauce, and I really think it’s an important ingredient for this casserole. Dijon mustard is pungent and made with white wine. It makes everything you use it in taste elevated and just a little more elegant.

Barbara’s Tips + Notes
- Warm the milk in the microwave before adding to the sauce. It will speed things up.

- Try using Ritz crackers instead of panko bread crumbs.
- You can leave out the wine and add lemon juice instead.

This was good for a rainy cool spring dinner. Even the grumpy teen who said he didn’t like chicken cordon bleu ate quite a bit of it. Served with rice, broccoli, and sourdough bread. I could see maybe baking it with cooked rice too? Might try that next time.

Always a win when you can get a teenager to try something new! Glad you liked it.
