1-Step 1: Preheat and Prep First, preheat your oven to 375°F and lightly grease a 13×9-inch casserole dish to prevent sticking. This step sets the stage for even cooking and ensures your casserole comes out just right. While the oven heats, shred your cooked chicken this can be done quickly using a hand mixer on medium speed for about a minute, as mentioned in helpful tips from similar recipes.

2-Step 2: Mix the Base In a large bowl, combine the 2 cans of condensed cream of chicken soup, 1 cup of sour cream, 1½ teaspoons onion powder, 1½ teaspoons garlic powder, 1 teaspoon kosher salt, and 1 teaspoon ground black pepper. Once mixed, fold in the 8 cups of shredded cooked chicken and 1½ cups of shredded cheddar cheese until everything is evenly coated. This creates the creamy heart of the casserole, blending flavors smoothly.

3-Step 3: Assemble the Dish Transfer the mixture to your prepared casserole dish, spreading it out evenly for consistent baking. In another bowl, mix the 2 full sleeves of lightly crushed crackers with 4 tablespoons of melted butter, then sprinkle this over the chicken mixture for a crispy top. Finish by adding the remaining ½ cup of cheddar cheese on top, which melts into a delicious layer as it bakes.

4-Step 4: Bake and Rest Bake the casserole for 35 to 40 minutes until it’s bubbling and the topping turns lightly browned. After baking, let it cool and thicken for 15 to 20 minutes before serving this rest time helps the sauce set and makes it easier to dish out. For variations, you can incorporate partially cooked vegetables like broccoli or carrots right into the mix, as suggested in our baked cheesy broccoli chicken patties recipe for added nutrition.
