Essential Ingredients for Chicken & Rice Bake

This ultimate leftover makeover comes together with just a handful of simple pantry staples.

  • Chicken: 3 cups cooked chicken, chopped or shredded
  • Rice: 3 cups cooked rice (white or brown)
  • For the Creamy Sauce:
    • 1 can (10.5 oz / 295g) condensed cream of chicken soup
    • 1 cup milk
    • ½ cup sour cream
  • Vegetables: 1 cup frozen peas
  • Cheese: 2 cups shredded sharp cheddar cheese, divided
  • Seasoning: Salt and black pepper to taste

Ingredients Notes

A little more detail on our key ingredients will ensure your casserole is perfectly creamy and delicious.

  • The Leftover Chicken: The beauty of this recipe is that it is the perfect way to use up any kind of leftover cooked chicken you have. A store-bought rotisserie chicken is a fantastic and convenient option. You can use either shredded or cubed chicken for this casserole.
  • The Leftover Rice: This recipe is specifically designed to use pre-cooked rice, making it another great way to use up leftovers from a previous meal. You can use either white or brown rice for this dish. Using rice that has been cooked and then cooled helps it to hold its texture better in the casserole.
  • The Creamy Sauce: For the ultimate ease and a wonderfully creamy and savory texture, this recipe uses a can of condensed cream of chicken soup as its base. The addition of a little milk helps to thin it out, while the sour cream adds a wonderful, subtle tang and an extra layer of richness to the final dish.
  • The Cheese: A good, sharp cheddar cheese will provide the best, boldest, and most classic cheesy flavour for this comforting casserole. For the absolute creamiest and most even melt, it is always best to buy a block of cheddar cheese and shred it yourself just before using.

How to Make The Best Chicken & Rice Bake

Let’s walk through the incredibly simple steps to assemble and bake this comforting leftover makeover.

  • Step 1: Prepare the Oven and Casserole Dish. First, preheat your oven to 175°C (350°F). Lightly grease a 9×13 inch or similar-sized casserole dish.
  • Step 2: Create the Casserole Mixture. In a large mixing bowl, combine the cooked shredded chicken, the cooked rice, and the frozen peas.
  • Step 3: Make the Creamy Sauce. In a separate medium bowl, whisk together the can of condensed cream of chicken soup, the milk, and the sour cream until the mixture is completely smooth. Season the sauce with a little salt and pepper.
  • Step 4: Combine Everything. Pour the prepared creamy sauce into the large bowl with the chicken and rice mixture. Add 1 cup of the shredded cheddar cheese to the bowl. Gently stir everything together until all the ingredients are evenly combined and coated in the creamy sauce.
  • Step 5: Assemble and Bake. Pour the chicken and rice mixture into your prepared baking dish and spread it out into an even layer. Sprinkle the remaining 1 cup of shredded cheese evenly over the top of the casserole.
  • Step 6: Bake to Bubbly Perfection. Bake the casserole, uncovered, for 20-25 minutes. The casserole is done when it is heated all the way through and the cheese on top is completely melted and bubbly.
  • Step 7: Rest and Serve. Let the casserole rest for at least 5 minutes before you serve it. This allows the creamy sauce to set up slightly, making it easier to serve.

Storage Options

This easy chicken and rice casserole makes for fantastic leftovers for a quick and comforting lunch. Once the casserole has cooled completely, you can either cover the baking dish tightly with foil or transfer individual portions to an airtight container. It will stay fresh in the refrigerator for up to 4 days and can be easily reheated in the microwave.

Variations and Substitutions

This classic comfort food casserole is a wonderful template that you can easily adapt based on the leftovers you have on hand. You can add any other leftover cooked vegetables you have, such as broccoli, corn, or green beans, to the mixture. For a different flavour profile, you can use a can of condensed cream of mushroom or cream of celery soup. For a crunchy topping, feel free to sprinkle some crushed buttery crackers or French’s fried onions over the cheese during the last 5 minutes of baking.

Practical & Valuable Tips

For the best texture, it’s a great idea to use rice that has been cooked and then cooled down, as this helps the grains to stay separate and not become mushy in the casserole. For the absolute creamiest and most flavourful result, be sure to use a full-fat sour cream and a sharp cheddar cheese. Finally, letting the finished casserole rest for a full 5 to 10 minutes before you serve it is a crucial step that helps the layers to set up for beautiful, clean slices.

Frequently Asked Questions

  1. Can I make this casserole with uncooked rice? It is not recommended for this specific recipe, as it is designed to use pre-cooked rice. To make this with uncooked rice, you would need to significantly increase the amount of liquid (like milk and chicken broth) and the baking time to ensure the rice cooks through properly.
  2. My casserole was a little bland. How can I add more flavor? A simple way to boost the flavour is to be more generous with your salt and pepper. You could also add a teaspoon of garlic powder and onion powder to the cream sauce, or sauté a small, chopped onion in a little butter before mixing it into the casserole.
  3. Can I assemble this casserole a day ahead of time? Yes, this is a fantastic make-ahead meal! You can fully assemble the entire casserole in your baking dish, cover it tightly, and store it in the refrigerator for up to 24 hours. You may just need to add an extra 5 to 10 minutes to the baking time since you will be starting with a cold dish.
  4. Can I use Greek yogurt instead of sour cream? Yes, absolutely! Plain Greek yogurt is a fantastic and healthier substitute for sour cream. It will provide a similar tangy flavour and a wonderful creamy texture, with an extra boost of protein.
  5. Does this casserole freeze well? Yes, this casserole freezes very well. I recommend assembling and baking it first, then letting it cool completely. You can freeze either the whole casserole or individual portions in freezer-safe containers for up to 3 months.

This Easy Cheesy Chicken and Rice Bake is the ultimate “leftover rescue” mission.
