Preparation

Follow these step-by-step instructions for making this delicious casserole.

Step 1: Preheat the Oven

Begin by preheating your oven to 375°F (190°C). While the oven heats, prepare your ingredients by steaming the broccoli and shredding the cooked chicken.

Step 2: Make the Creamy Base

In a large mixing bowl, combine the cream of chicken soup, mayonnaise or sour cream, 1 cup of shredded cheddar cheese, milk, garlic powder, onion powder, salt, and pepper. Whisk these ingredients together until smooth and well combined. The mixture should be creamy and thick, with the cheese well incorporated into the sauce.

Step 3: Add the Chicken and Broccoli

Add the shredded chicken and steamed broccoli florets to the bowl with the creamy sauce. Stir gently until everything is well combined. The chicken and broccoli should be evenly coated with the creamy mixture, ensuring that every bite will be flavorful and delicious.

Step 4: Pour Into a Baking Dish

Next, grease a baking dish (about 9×13 inches) with cooking spray or butter. Pour the chicken and broccoli mixture into the prepared dish, spreading it out evenly. Smooth the top with a spatula to ensure even cooking.

Step 5: Add More Cheese

Sprinkle the remaining 1/2 cup of shredded cheddar cheese evenly over the top of the casserole. This layer of cheese will melt beautifully during baking, creating a rich, cheesy crust on top.

Step 6: Prepare the Topping

In a small bowl, mix the crushed crackers or breadcrumbs with the melted butter. Stir until the crumbs are fully coated in butter, forming a slightly clumpy mixture. This step is essential for getting that perfectly golden and crispy topping.

Step 7: Add the Topping

Sprinkle the buttered breadcrumb mixture evenly over the top of the casserole. This will give the dish a delightful crunch that contrasts with the creamy filling.

Step 8: Bake the Casserole

Place the casserole in the preheated oven and bake for 25-30 minutes. The casserole is done when the cheese is bubbly, and the topping is golden brown. Be careful not to overbake, as this could dry out the chicken.

Step 9: Serve and Enjoy

Once done, remove the casserole from the oven and let it rest for about 5 minutes before serving. Garnish with freshly chopped parsley if desired. Serve the casserole warm and enjoy its creamy, cheesy, and savory goodness!
