• Making Chicken Cordon Bleu Casserole is easy and requires just a handful of ingredients that you likely already have in your kitchen. This simple yet hearty dish combines tender chicken savory ham, and melted cheese to create the perfect comfort meal. Here's what you’ll need to make this delicious casserole:
• Boneless Skinless Chicken Breasts – About 3 cups of cooked chicken, chopped or shredded. You can also use raw chicken if you prefer to cook it fresh, but pre-cooked chicken can save you time. Using chicken thighs is another great option for a juicier texture.

Ham – Use thinly sliced deli ham or leftover ham from another meal. Cut it into strips or cubes. The ham adds that signature salty, savory flavor that pairs perfectly with the chicken. If you're looking for a twist, try using chicken Cordon Bleu casserole with stuffing to add a different texture and flavor.

Swiss Cheese – Traditional Chicken Cordon Bleu calls for Swiss cheese, which melts beautifully and adds that creamy, nutty flavor. You can substitute with Gruyère for a more robust taste or mozzarella for a milder option. If you’re aiming for a healthy chicken Cordon Bleu casserole, consider a reduced-fat version.

Cheddar Cheese – Adding cheddar cheese brings a sharpness and extra creaminess to the casserole. Feel free to use extra sharp cheddar for a bolder flavor. You can also mix in some Keto-friendly cheeses if you’re making a low-carb version of this casserole.

Heavy Cream – For the creamy sauce that binds everything together, you’ll need about 1 cup of heavy cream. For a lighter, healthier version, you can substitute with half-and-half or even a dairy-free alternative like coconut milk.

Breadcrumbs – To top off the casserole and give it that crispy, golden crust, use about 1 cup of breadcrumbs. You can opt for traditional breadcrumbs, whole wheat breadcrumbs, or panko breadcrumbs for an extra crispy texture. For a gluten-free version, use gluten-free breadcrumbs.

Mustard – A tablespoon of Dijon or yellow mustard adds a tangy kick that complements the richness of the cheese and chicken. It’s a small amount, but it really makes a difference in flavor.

Seasonings – To bring all the flavors together, you’ll need:

Salt and pepper, to taste

1 teaspoon of garlic powder

1 teaspoon of onion powder

1 teaspoon of dried thyme or Italian seasoning

Fresh Parsley (Optional) – A sprinkle of fresh parsley on top before serving adds a burst of color and freshness, plus a little extra flavor.
