Essential Ingredients for Sour Cream Chicken Casserole

This incredibly creamy and comforting casserole comes together with a handful of simple pantry staples.

  • Chicken: 3 cups cooked chicken, shredded or cubed (rotisserie chicken is perfect)
  • Rice: 3 cups cooked white or brown rice
  • For the Creamy Sauce:
    • 1 can (10.5 oz / 295g) condensed cream of chicken soup
    • 1 cup full-fat sour cream
    • ½ cup milk
  • Aromatics: 1 small onion, finely chopped
  • 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 as creamy and comforting as possible.

  • The Chicken: The beauty of this recipe lies in its convenience, making it the perfect way to use up a store-bought rotisserie chicken or any leftover cooked chicken you have on hand. You can use either shredded or cubed chicken for this casserole. A combination of both white and dark meat will provide the most flavour.
  • The Rice: This recipe is designed to use pre-cooked rice, making it another fantastic 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 slightly cooled will help it to hold its texture and not become mushy in the casserole.
  • The Creamy Sauce: Our incredibly easy and creamy sauce is made with a combination of condensed cream of chicken soup and our secret ingredient, full-fat sour cream. The sour cream provides a wonderful, luscious creaminess and a subtle tangy flavour that perfectly balances the richness of the dish. It is very important to use a full-fat sour cream for the best texture and to prevent the sauce from becoming watery.
  • The Cheese: A good, sharp cheddar cheese will provide the best, most classic, and bold cheesy flavour for this comfort food 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 Ultimate Sour Cream & Chicken Bake

Let’s walk through the simple steps to assemble and bake this incredibly creamy comfort food dinner.

  • Step 1: Prepare Your Oven and Casserole Mixture. First, preheat your oven to 175°C (350°F) and lightly grease a 9×13 inch baking dish. In a large mixing bowl, combine the cooked shredded chicken, the cooked rice, and the finely chopped onion.
  • Step 2: Create the Creamy Sour Cream Sauce. In a separate medium bowl, whisk together the can of condensed cream of chicken soup, the full-fat sour cream, and the milk until the mixture is completely smooth. Season the sauce with a little salt and pepper to your taste.
  • Step 3: Combine Everything. Pour the prepared sour cream 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 rich, creamy sauce.
  • Step 4: 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 5: Bake to Bubbly Perfection. Bake the casserole, uncovered, for 25-30 minutes. The casserole is done when it is heated all the way through and the cheese on top is completely melted, bubbly, and slightly golden brown.
  • Step 6: Rest and Serve. Let the casserole rest for at least 5 to 10 minutes before you serve it. This allows the creamy sauce to set up slightly, making it much easier to serve.

Storage Options

This creamy 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 to your family’s tastes. To add some extra vegetables, you can stir in about a cup of steamed broccoli florets or a can of drained mixed vegetables to the casserole mixture. 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. You can also easily substitute the chicken with leftover cooked turkey, which is perfect after a holiday.

Practical & Valuable Tips

For the creamiest possible sauce, it is very important to use a full-fat sour cream, as lower-fat versions can sometimes become watery when baked. For the best flavour and texture, always use pre-cooked rice that has had a chance to cool down, as this helps the grains to stay distinct and not become mushy in the casserole. Finally, letting the finished casserole rest on the counter for a full 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 use Greek yogurt instead of sour cream to make it healthier? Yes, you can absolutely substitute the sour cream with an equal amount of full-fat, plain Greek yogurt. This is a fantastic way to add an extra boost of protein to the dish while still maintaining a wonderful creamy and tangy flavour.
  2. My casserole was too thick. What can I do? If your casserole mixture seems too thick before you bake it, you can simply stir in an extra splash or two of milk until it reaches your desired consistency. Different types of rice can absorb different amounts of liquid, so feel free to adjust.
  3. Can I assemble this entire casserole a day ahead of time and bake it later? Yes, this is a perfect 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 10 to 15 minutes to the baking time since you will be starting with a cold dish.
  4. Can I use a different type of condensed soup? Of course! While cream of chicken soup is a classic choice, this casserole would also be delicious and just as creamy if made with a can of condensed cream of mushroom or cream of celery soup.
  5. What vegetables are good to add to this casserole? This casserole is a perfect place to add some extra vegetables. A cup of frozen peas and carrots (thawed), some steamed broccoli florets, or some sautéed, sliced mushrooms would all be fantastic and delicious additions to the chicken and rice mixture.
