Step‑by‑Step Instructions for CHICKEN CORDON BLEU CASSEROLE
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). While your oven heats up, take a moment to grease a 9×13 inch baking dish with cooking spray or butter to ensure that your casserole doesn’t stick. This step will make it easier to serve your delicious Chicken Cordon Bleu Casserole once it’s baked!
Step 2: Combine Ingredients
In a large mixing bowl, combine 3 cups of cooked and shredded chicken, 1 ½ cups of diced ham, and 1 ½ cups of shredded Swiss cheese. Stir everything together until the ingredients are evenly mixed. This hearty mixture will form the base of your casserole, showcasing the flavors of the chicken and savory ham beautifully.
Step 3: Make the Sauce
In a separate bowl, whisk together ½ cup of sour cream, ¼ cup of milk, 1 tablespoon of Dijon mustard, ½ teaspoon of garlic powder, ½ teaspoon of onion powder, and a pinch of salt and pepper. This creamy sauce will bring the casserole together, creating a luscious coating for the chicken and ham mixture.
Step 4: Combine the Mixtures
Pour the creamy sauce over the chicken and ham mixture in your large bowl. Gently stir with a spatula or wooden spoon until all the ingredients are well coated in the sauce. This ensures each bite of your Chicken Cordon Bleu Casserole is rich and flavorful, enhancing the comforting nature of the dish.
Step 5: Transfer to Baking Dish
Spread the combined mixture evenly into your prepared 9×13 inch baking dish. Take your time to ensure an even layer, which promotes even cooking. Then, sprinkle the remaining ½ cup of Swiss cheese on top for that perfect, gooey finish that complements the flavors of the casserole wonderfully.
Step 6: Add the Topping
In a small bowl, mix ½ cup of bread crumbs with 2 tablespoons of melted butter until well combined. This will create a crispy topping for your casserole. Carefully sprinkle this mixture evenly over the cheese to add a delightful crunch that contrasts with the creamy layers beneath.
Step 7: Bake the Casserole
Place the baking dish in your preheated oven and bake for 25-30 minutes. Keep an eye on it and look for the cheese to become bubbly and golden brown. This signifies that your Chicken Cordon Bleu Casserole is hot and ready to be taken out of the oven, releasing an irresistible aroma into your kitchen.
Step 8: Cool & Serve
Once baking is complete, remove the casserole from the oven and allow it to cool for about 5-10 minutes. This cooling period helps the casserole set, making it easier to serve. Scoop out hearty portions and enjoy the comforting flavors of this Chicken Cordon Bleu Casserole with family or friends!
