Ingredients List for Creamy Chicken Cordon Bleu Casserole Recipe

To make this creamy, cheesy casserole, you’ll need the following ingredients:

• 3 cups cooked chicken, shredded or cubed (rotisserie chicken works great for ease)
• 1 cup turkey, diced or thinly sliced
• 2 cups Swiss cheese, shredded
• 1 ½ cups milk
• 1 cup heavy cream
• 1/2 cup sour cream (adds a lovely tang to the sauce)
• 1/4 cup Dijon mustard (for that signature tangy kick)
• 1/4 cup Parmesan cheese, grated

• Optional: Fresh parsley for garnish

This ingredient list gives you the perfect balance of creamy, savory flavors while keeping the process simple.

Substitutions and Variations

One of the joys of making a chicken casserole is the ability to adapt the recipe based on what you have on hand or dietary preferences. Here are some smart substitutions and tasty variations you can try:

• Cheese Alternatives: Not a fan of Swiss cheese? Mozzarella or Gruyère will give you that same creamy meltiness with a slightly different flavor profile. For a sharper twist, try white cheddar.
• Gluten-Free Option: Swap out the breadcrumbs for gluten-free breadcrumbs, and make sure any pre-cooked chicken is gluten-free as well.
• Low-Carb Version: If you’re watching carbs, you can skip the breadcrumbs altogether or use crushed pork rinds for a crunchy topping.
• Healthier Twist: To lighten up the casserole, use light sour cream and half-and-half in place of heavy cream. You can also add steamed broccoli or spinach for some extra veggies.

Creamy Chicken Cordon Bleu Casserole Step-by-Step Cooking Instructions

Step 1: Prepare the Chicken and Turkey

Start by pre-cooking your chicken if it’s not already cooked. Rotisserie chicken is a great time-saver here. Cube or shred the chicken into bite-sized pieces and set aside. Dice the turkey or thinly slice it into small strips.

Step 2: Make the Creamy Sauce

In a medium saucepan, whisk together the milk, heavy cream, Dijon mustard, and minced garlic over medium heat. Let the mixture simmer until it thickens slightly, about 5-7 minutes. Stir in the sour cream, salt, and pepper, and remove from heat. This sauce will provide the luscious creaminess that ties the entire casserole together.

Step 3: Assemble the Casserole

In a large casserole dish, start by layering half of the chicken at the bottom. Next, add a layer of diced turkey, then a layer of shredded Swiss cheese. Pour half of the creamy sauce over the layers. Repeat the layers—chicken, turkey, cheese—and finish with the remaining sauce poured on top.

Step 4: Add the Topping

In a small bowl, mix together the breadcrumbs and melted butter. Sprinkle this mixture evenly over the casserole for that perfect crunchy finish.

Step 5: Bake

Preheat your oven to 350°F (175°C). Bake the casserole for 25-30 minutes, or until the top is golden brown and the sauce is bubbling around the edges. If you like a little extra crisp, you can pop it under the broiler for the last 2-3 minutes.

Step 6: Garnish and Serve

Once your creamy chicken cordon bleu casserole is out of the oven, let it rest for 5 minutes before serving. Garnish with freshly chopped parsley for a pop of color and flavor.

Common Mistakes to Avoid While Preparing Creamy Chicken Cordon Bleu Casserole

1. Overcooking the Chicken: Pre-cooked chicken can easily dry out, so make sure you don’t overbake the casserole.
2. Skipping the Resting Time: Allow the casserole to rest before serving. This helps the sauce thicken and makes serving easier.
3. Using Too Much Mustard: Dijon adds a tangy punch, but too much can overpower the dish. Stick to the recipe’s measurements for balance.
