This hearty Chicken Cordon Bleu Casserole takes the fancy French classic and turns it into a cozy family dinner. You'll love how the juicy shredded chicken mingles with top-quality black forest ham and gooey Swiss cheese, all wrapped in a silky sauce and topped with crunchy Panko crumbs. It keeps all the tasty flavors you'd expect but comes together way easier than the traditional rolled-up version.
I've made this so many times now and it's my go-to when I want to wow dinner guests without being stuck in the kitchen forever.
Stellar Ingredients Guide
- Chicken: Grab a rotisserie chicken to save time and add flavor.
- Ham: Go for black forest ham for the tastiest results.
- Swiss Cheese: Get it freshly sliced at the deli counter for the best melt.
- Dijon Mustard: Brings that essential tang to the dish.
- Panko Breadcrumbs: They're the secret to that irresistible crispy top.
- Whole Milk: Don't substitute—it makes the sauce super creamy.
Assembling Your Dish
- Foundation Building:
- Spread your shredded chicken in an even layer at the bottom.
- Sauce Magic:
- Pour milk into your roux bit by bit for an extra smooth sauce.
- Meat and Cheese Layers:
- Arrange ham and cheese carefully for the best flavor in every bite.
- Crunchy Finish:
- Mix butter with Panko to get that gorgeous golden topping.
- Putting It All Together:
- Drizzle sauce everywhere and sprinkle with buttered crumbs before it hits the oven.

The tiny pinch of nutmeg in the cream sauce is my favorite touch. It's that little something extra that makes folks think you got this from a fancy restaurant.
Tasty Side Dish Ideas
Try it with some oven-roasted asparagus or a simple green salad to cut through the richness. Steamed broccoli works great too.
Custom Touches
Try swapping in Gruyère cheese or toss in a layer of cooked mushrooms if you want to switch things up.
Keeping Leftovers Fresh
You can store any extras in the fridge for about three days. Warm it up in the oven so your topping stays crispy.

Every time I make it, I'm reminded that putting a new spin on old classics often leads to the yummiest meals.
