1-Getting started with this chicken casserole begins with simple steps that lead to a delicious outcome. First, preheat your oven to 375°F (190°C) and lightly spray a 13×9-inch casserole dish with cooking spray to prevent sticking. This sets the stage for even baking and easy cleanup.

2-Next, in a large bowl, stir together the condensed cream of chicken soup, sour cream, onion powder, garlic powder, salt, and pepper until well blended. Then, fold in the shredded cooked chicken and 1½ cups of the shredded cheddar cheese to mix everything evenly. Transfer this mixture to your prepared casserole dish for the base layer.

3-Now, in a medium bowl, mix the crushed crackers with melted butter to create a crunchy topping. Sprinkle this over the chicken filling, and top with the remaining ½ cup of shredded cheddar cheese for that extra cheesy finish. Bake for 35 to 40 minutes until the filling bubbles and the crackers turn lightly browned, then let it cool for 15 to 20 minutes before serving to thicken up.
