Ritz Chicken Casserole

Ritz Chicken Casserole is one of those meals that reminds me how useful a few simple ingredients can be. You get tender chicken, a creamy sauce, melted cheese, and that buttery Ritz cracker topping all baked together until hot and golden.

I usually make this when I have cooked chicken ready to use and don’t want to turn dinner into a big project. There is very little chopping involved, and the filling comes together in one bowl.

The cracker topping is what keeps me coming back to this casserole. Ritz crackers become buttery and crisp in the oven, giving the soft and creamy chicken underneath a little crunch in every bite.

It is also easy to change depending on what you have in the kitchen. Add a little broccoli, use rotisserie chicken, or swap the cheese for another mild variety. The basic recipe is simple enough that you can make it your own.

Ingredients for Ritz Chicken Casserole

For the Chicken Filling

2 cups cooked chicken, chopped: Cooked chicken breast works well, but rotisserie chicken is an easy shortcut. Cut it into small pieces so the chicken spreads evenly throughout the casserole.
1 can cream of chicken soup: This forms the creamy base of the casserole and keeps the chicken moist as it bakes.
1/2 cup sour cream: Sour cream adds a little tang and makes the sauce creamy without making it too heavy.
1/2 cup shredded cheddar cheese: Cheddar brings a mild, savory cheesiness to the filling and melts nicely as the casserole cooks.
1/4 cup chicken broth: A small amount of broth loosens the sauce so it stays creamy instead of becoming too thick in the oven.
1/2 teaspoon garlic powder: Garlic powder gives the filling a little extra flavor while keeping the seasoning simple.
1/4 teaspoon black pepper: Pepper adds gentle seasoning and helps balance the creamy ingredients.
1/4 teaspoon salt, or to taste: Add only a little because the soup, cheese, chicken, and crackers can already contain quite a bit of salt.

For the Ritz Topping

1 sleeve Ritz crackers: Crush the crackers into small pieces rather than a fine powder. This gives the topping a better crunch and lets the buttery flavor come through.
3 tablespoons melted butter: Butter coats the crackers and helps them become golden, crisp, and flavorful while baking.
2 tablespoons shredded cheddar cheese: A little extra cheese over the top adds another layer of flavor and helps the topping feel more complete.

How to Make Ritz Chicken Casserole

Preheat the oven: Heat your oven to 375°F and lightly grease an 8×8-inch or similar-sized baking dish. This keeps the creamy filling from sticking and makes serving easier.
Prepare the chicken: If you are using leftover chicken, cut it into small bite-size pieces. You want the pieces small enough to mix easily with the sauce so that every serving gets a good amount of chicken.
Make the creamy mixture: Add the cream of chicken soup, sour cream, chicken broth, garlic powder, black pepper, and salt to a large bowl. Stir everything together until the sauce is smooth and evenly seasoned.
Add the chicken and cheese: Fold the chopped chicken and 1/2 cup of shredded cheddar into the sauce. Stir gently until all of the chicken is coated and the cheese is spread throughout the mixture.
Fill the baking dish: Spoon the chicken mixture into the prepared baking dish and spread it into an even layer. Make sure the filling reaches the corners so it cooks evenly from one side of the dish to the other.
Crush the Ritz crackers: Place the crackers in a sealed bag and gently crush them with your hands or the bottom of a glass. Aim for small crumbs and pieces rather than turning them completely into powder, because larger pieces give the topping more texture.
Mix the topping: Add the crushed Ritz crackers to a bowl with the melted butter and stir until the crumbs are lightly coated. The butter should reach most of the crackers so they brown evenly in the oven.
Top the casserole: Sprinkle the buttery Ritz mixture evenly over the chicken filling. Add the remaining 2 tablespoons of cheddar over the top so the cheese melts into the cracker layer as everything bakes.
Bake until bubbly: Place the casserole in the preheated oven and bake for about 25 to 30 minutes. Look for bubbling around the edges, a hot center, and a golden-brown cracker topping.
Watch the topping: If the Ritz crackers become golden before the casserole is completely hot, loosely cover the dish with foil for the remaining baking time. This protects the crackers from becoming too dark.
Let it rest: Take the casserole out of the oven and let it sit for about 5 minutes before serving. The short rest helps the creamy filling settle slightly, making it easier to scoop onto plates.
Serve warm: Spoon the chicken and creamy sauce onto each plate, making sure to get plenty of the buttery Ritz topping with every serving. The contrast between the creamy filling and crisp topping is best while it is still warm.

What to Serve Ritz Chicken Casserole With

I like keeping the sides fairly light because the casserole already has a creamy filling and buttery cracker topping. Steamed broccoli, green beans, peas, or roasted carrots all fit nicely. A simple green salad with a tangy dressing is another good option and adds some freshness to the plate.

If you want a more filling dinner, mashed potatoes or roasted potatoes work well with the chicken and creamy sauce. You could also serve it with cooked rice, especially if you want something that can soak up some of the extra sauce. I would skip adding another rich side because the casserole itself is already quite satisfying.

How to Store and Reheat Ritz Chicken Casserole

Store leftover casserole in an airtight container or cover the baking dish tightly and refrigerate it for up to 3 to 4 days. The Ritz topping will soften in the refrigerator, but you can bring some of the crunch back by reheating the casserole in a 350°F oven for about 10 to 15 minutes, depending on the portion size.

An air fryer works well for individual portions too. The microwave is convenient when you are short on time, although the cracker topping will be softer.
