Essential Ingredients

Here’s what you’ll need to make the perfect Creamy Chicken Cordon Bleu Casserole:

Main Ingredients

• 3 cups cooked chicken, shredded or cubed – You can use rotisserie chicken to save time.
• 1 ½ cups diced ham – Leftover holiday ham works great here.
• 2 cups shredded Swiss cheese – Adds that classic Cordon Bleu flavor.
• 1 cup shredded mozzarella or Monterey Jack cheese – Helps create a creamier texture.

For the Creamy Sauce

• 1 can (10.5 oz) cream of chicken soup – The creamy base of your casserole.
• 1 cup sour cream – Adds tang and richness.
• 1 teaspoon Dijon mustard – Gives a subtle depth and signature flavor.
• ½ teaspoon garlic powder
• Salt and black pepper to taste

Topping

• 1 cup breadcrumbs (Panko or regular) – For a crispy top.
• 2 tablespoons melted butter – Helps brown the topping beautifully.
• ¼ cup grated Parmesan cheese – Adds a salty, cheesy crunch.

Optional Add-ins

• Steamed broccoli or spinach – For a veggie boost.
• Cooked pasta or rice – To turn it into a more filling one-pan meal.

Substitutions & Variations

• Swap Swiss cheese for Gruyère for a gourmet twist.
• Replace sour cream with Greek yogurt for a lighter option.
• Use turkey instead of chicken for a post-holiday casserole.

Step-by-Step Instructions

Step 1: Prepare Your Ingredients

Start by preheating your oven to 350°F (175°C) and greasing a 9×13-inch baking dish.
Shred or cube your cooked chicken and dice your ham into small, bite-sized pieces.

Step 2: Make the Creamy Sauce

In a large mixing bowl, combine:

• Cream of chicken soup
• Sour cream
• Dijon mustard
• Garlic powder
• Salt and pepper

Whisk until smooth. Taste and adjust the seasoning if needed.

Step 3: Combine the Chicken and Ham

Add the shredded chicken and diced ham to the sauce mixture. Stir until everything is evenly coated in the creamy sauce.

Step 4: Layer the Casserole

Pour half of the creamy chicken and ham mixture into your prepared baking dish.
Sprinkle half of the shredded Swiss and mozzarella cheese over it.
Then add the remaining chicken mixture, and top with the rest of the cheese.

Step 5: Prepare the Topping

In a small bowl, mix the breadcrumbs, melted butter, and Parmesan cheese until evenly coated. Sprinkle this mixture evenly over the top of the casserole.

Step 6: Bake

Bake uncovered in the preheated oven for 25–30 minutes, or until the casserole is bubbling and the top is golden brown.

Step 7: Let It Rest

Allow the casserole to cool for about 5 minutes before serving. This helps the sauce thicken and makes slicing easier.

Assembly Tips and Presentation

• For a restaurant-style look, sprinkle chopped parsley on top before serving.
• Serve with a side of steamed vegetables, green salad, or buttered noodles.
• If you want to add texture, include crushed Ritz crackers in place of breadcrumbs for a buttery topping.

For a fancy touch, layer thin slices of ham and cheese between chicken layers before baking to mimic the traditional Cordon Bleu structure.
