Rotisserie Chicken Casserole: Creamy Chicken and Cracker Bake
This rotisserie chicken casserole is a savoury American dinner that combines shredded chicken with a thick sauce of sour cream and chicken broth. You bake it in a 20 cm × 20 cm baking dish until the edges bubble. The dish features a rich, creamy texture contrasted by a golden crust of crushed Ritz crackers. It provides a substantial meal that pairs well with buttered noodles or rice to absorb the sauce.
Control the heat of your oven at 175°C (350°F) to ensure the topping browns without burning. You must let the casserole rest for 5 minutes before serving. This pause allows the flavours to settle and the sauce to thicken. Without this resting period, the mixture may be too loose, making it difficult to serve clean portions. Sauté the onion until translucent before adding it to the bowl to remove the raw sharpness.

Recipe cardIngredients
Instructions
-
Prepare the oven
Preheat your oven to 175°C (350°F). Ensure the oven reaches this temperature before the dish goes in to guarantee even cooking.
-
Shred the chicken
Use two forks to shred the cooled rotisserie chicken. Place the meat into a large mixing bowl.
-
Sauté the onion
Heat a medium skillet over medium heat. Cook the diced onion for 5 minutes until translucent, which removes the raw bite and adds a savoury base.
-
Combine the base
Stir the sautéed onion into the chicken. Mix in the sour cream, cream of chicken soup, chicken broth, salt, pepper, garlic powder, dried thyme, and frozen peas until the sauce is well combined.
-
Fold in cheese
Pour the melted butter over the chicken mixture. Fold in the shredded cheddar cheese until it has partly melted to bind the casserole together.
-
Assemble the dish
Transfer the mixture into a greased 20 cm x 20 cm baking dish. Smooth the surface with a spatula and sprinkle the crushed Ritz crackers evenly over the top to create a crisp crust.
-
Bake the casserole
Bake for 25 minutes. Look for the edges to bubble and the cracker topping to turn golden brown, which indicates the centre is heated through.
-
Rest the dish
Remove the dish from the oven and let it rest for 5 minutes. This allows the flavours to settle and the sauce to thicken for easier serving.
Watch the cracker topping carefully during the final minutes of baking. If the crackers brown too quickly before the edges bubble, cover the dish loosely with foil to prevent burning while the sauce finishes cooking.
What to serve with it
Pair this dish with a crisp green salad dressed in lemon vinaigrette to cut through the richness. You may also serve it over buttered noodles or rice to absorb the creamy sauce. For a more substantial meal, accompany the casserole with boiled or roasted baby potatoes.
Storing and reheating
Store leftovers covered in the refrigerator for up to 3 days. Freeze individual portions in airtight containers for up to 2 months. To reheat frozen portions, thaw them overnight in the refrigerator and bake at 175°C (350°F) for 20 minutes until the centre is hot.

Questions people ask
Can I make this dairy-free
Yes. Use a plant-based sour cream and a vegan cheese that melts well. You can also substitute the dairy components with coconut milk to maintain the creamy texture while removing the lactose.
How do I keep the cracker topping from burning
Ensure your oven is preheated to 175°C (350°F) and bake for exactly 25 minutes. If the crackers brown too quickly, cover the dish loosely with foil to protect the crust while the base finishes.
Can I freeze the casserole before baking
Yes. Freeze the unbaked mixture in a tightly covered dish. Reheat it directly from the freezer in the oven at 175°C (350°F) for 30 minutes or until it is fully heated through.
