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 the oven is warming up, take a moment to grease a 9x13 inch baking dish with non-stick cooking spray or butter, ensuring it's ready for the delightful Chicken Cordon Bleu Casserole that you'll be putting together shortly.
Step 2: Mix the Chicken and Ham
In a large mixing bowl, combine 3 cups of shredded or cubed cooked chicken with 1½ cups of diced cooked ham. Stir in 1 cup of shredded Swiss cheese, creating a colorful and flavorful mixture. Take a moment to appreciate the savory aroma as you mix everything together, making sure the chicken and ham are evenly coated with cheese.
Step 3: Prepare the Creamy 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, and ½ teaspoon of onion powder until smooth. Add salt and pepper to taste, then enjoy the way the creamy sauce comes together. This will add a rich flavor profile to your Chicken Cordon Bleu Casserole.
Step 4: Combine Mixtures
Pour the prepared sauce over the chicken and ham mixture and stir gently to ensure everything is well-coated. This process should take just a minute, and you’ll notice the blend of flavors coming together beautifully. It’s perfect for lifting spirits on a busy weeknight!
Step 5: Transfer to Baking Dish
Carefully transfer the mixture into your greased baking dish, spreading it evenly across the bottom. Take a moment to smooth out the top with a spatula so that it bakes uniformly. The aroma of the Chicken Cordon Bleu Casserole will start to fill your kitchen.
Step 6: Add Cheese and Topping
Sprinkle the remaining 1 cup of shredded Swiss cheese over the top of the casserole. If you’re feeling adventurous, add a layer of ½ cup of bread crumbs mixed with 2 tablespoons of melted butter for a golden, crunchy topping. This step elevates the dish, adding a delightful texture that everyone will love.
Step 7: Bake to Perfection
Place the casserole in the preheated oven and bake for 25-30 minutes. You’ll know it’s done when the cheese is melted, bubbly, and just beginning to turn golden brown. Take this time to appreciate the comforting smells wafting through your kitchen; it’s a sure sign that a fantastic meal is on the way.
Step 8: Cool and Serve
Once baked, remove the Chicken Cordon Bleu Casserole from the oven and let it cool for a few minutes before serving. This step is important for allowing the layers to set, making it easier to slice.
