Step 1: Preheat the Oven

Start by preheating your oven to 350°F (175°C). This ensures that the casserole cooks evenly and reaches the perfect golden brown crust on top.

Step 2: Prepare the Casserole Mixture

In a large mixing bowl, combine the following ingredients:

• Shredded chicken

• Cream of mushroom soup

• Cream of chicken soup

• Sour cream

• Mayonnaise

• Worcestershire sauce

• Garlic powder

• Onion powder

• Salt

• Black pepper

Stir everything together until the mixture is fully combined and smooth. Then, add the following cheeses:

• Shredded sharp cheddar cheese

• Shredded mozzarella cheese

• Grated Parmesan cheese

Mix again until the cheese is evenly distributed throughout the chicken mixture.

Step 3: Layer the Casserole

Take a greased 9×13-inch baking dish and pour the chicken mixture into the dish. Spread it out evenly, making sure the entire bottom of the dish is covered.

Step 4: Add the Crouton Topping

In a small bowl, combine the seasoned croutons with melted butter. Stir them until the croutons are thoroughly coated in the butter. Once that’s done, sprinkle the croutons evenly over the top of the casserole. This will create a deliciously crunchy topping once baked.

Step 5: Bake the Casserole

Place the casserole in the preheated oven and bake for about 30-35 minutes. You’ll know it’s ready when the top is golden brown and the casserole is bubbling around the edges.

Step 6: Garnish and Serve

Once the casserole is finished baking, remove it from the oven and let it cool for a few minutes. This will help it set. If you like, garnish with a little chopped parsley or green onions for added flavor and color. Serve and enjoy your delicious meal!
