Step‑by‑Step Instructions for Chicken Cordon Bleu Casserole
Step 1: Preheat the Oven
Begin by preheating your oven to 375°F (190°C). This ensures your Chicken Cordon Bleu Casserole will cook evenly and develop that golden, bubbly top. While the oven warms up, gather your ingredients and equipment, such as a large mixing bowl and a greased baking dish, so you're ready to go!
Step 2: Mix the Ingredients
In a large mixing bowl, combine the shredded chicken, sliced ham, Swiss cheese, mozzarella cheese, and heavy cream. Add the Dijon mustard, garlic powder, onion powder, smoked paprika, salt, and pepper for extra flavor. Use a sturdy spatula or spoon to mix everything together until well combined, allowing the creamy goodness to envelop the chicken and cheese pieces.
Step 3: Transfer to the Baking Dish
Carefully transfer the hearty mixture from the bowl to your greased baking dish. Spread it evenly across the dish with your spatula, ensuring that every bite of the Chicken Cordon Bleu Casserole will have a delightful combination of flavors. This even layer will help the casserole cook uniformly and give you that perfect texture.
Step 4: Add the Topping
Now it’s time to add some crunch! Sprinkle the breadcrumbs evenly over the top of the casserole mixture. This will create a lovely, golden-brown crust as it bakes, adding a delightful contrast to the creamy filling. Make sure to cover the entire surface so that every bite enjoys that tasty crunch.
Step 5: Bake the Casserole
Place the baking dish in the preheated oven and bake for 30 to 35 minutes. Keep an eye on it during the last few minutes; you’re looking for that beautiful golden-brown topping and bubbling edges that signal the Chicken Cordon Bleu Casserole is ready to enjoy!
Step 6: Check for Doneness
As your casserole finishes baking, ensure it’s safe to eat. Use a kitchen thermometer to check that the center has reached at least 165°F (74°C). If you haven’t got a thermometer, a simple test is to look for bubbling around the edges and a firm filling. This means it's perfectly cooked and ready for serving.
