We may all be used to our chicken cordon bleu served as a whole chicken breast filled with ham, a delicious cheesy sauce, and a crispy coating. There is no denying its tastiness, but sometimes you want all the flavor without the time commitment. Introducing, the Chicken Cordon Bleu Casserole. All the goodness, great flavors, and none of the fuss—you will have this on the table in under an hour.

We love this recipe as a way to use up leftover chicken and ham. The casserole makes a great dish all on its own with some crusty bread and is especially good when served over pasta or with a tasty salad for something a little lighter.

Ingredients

  • 4 tablespoons all-purpose flour

  • 2 tablespoons unsalted butter

  • 1 cup whole milk

  • Kosher salt

  • 1 teaspoon mustard

  • Freshly ground black pepper

  • 3/4 cup grated sharp cheddar cheese

  • 3 cups shredded or chopped cooked chicken

  • 1 cup sliced or chopped ham

  • 1 cup breadcrumbs

  • 1/4 cup freshly grated Parmesan

  • For serving (optional): over pasta or with a salad

Steps to Make It

  2. Place the flour and butter in a medium saucepan over medium heat and cook, stirring constantly, for 2 to 3 minutes to make a simple roux.

  3. Add the milk and cook, whisking constantly, over medium heat until the sauce is thickened. If the sauce is too thick, then add a little milk at a time, as needed until the consistency is thick enough to be a pourable sauce.

Glass Bakeware Warning

For premade casseroles or leftovers that are in a glass baking dish and have been refrigerated, do not place directly into a hot oven as the glass can shatter. Instead, place any cold glass bakeware into a cold oven to warm up while it preheats. Or, allow the bakeware to rest outside of the fridge for 30 minutes to reach room temperature while the oven preheats.

Tips

You can give yourself a break and make it ahead of time and freeze the casserole to be eaten later. It will stay good in the freezer for 3 to 6 months.

Recipe Variations

The chicken cordon bleu recipe is mainly chicken (surprise!), but turkey works just as well.


This recipe uses sharp cheddar to make the creamy cheese sauce, but you can swap in Swiss or one of your other favorites if you like. Just make sure it is an easy melting cheese and has a strong flavor, or it may get lost in the other ingredients.
