Ingredients You’ll Need
For this easy leftover chicken and rice casserole, you will need a handful of basic ingredients.
Leftover Chicken
Use about 2 cups of cooked chicken, chopped or shredded. Rotisserie chicken is especially convenient, but leftover baked or roasted chicken works just as well.
If your chicken is already seasoned, you may want to reduce the amount of additional salt.
Cooked Rice
You will need approximately 3 cups of cooked rice. White rice, brown rice, basmati rice, or long-grain rice can work.
If you are using leftover refrigerated rice, break up any large clumps before adding it to the casserole.
Creamy Sauce
A simple combination of cream soup and milk creates a creamy base without requiring a complicated homemade sauce.
Cream of chicken soup is a classic choice, but cream of mushroom or cream of celery can also work.
Vegetables
Frozen peas and carrots are convenient because they require almost no preparation. You can also use a frozen mixed vegetable blend.
If you prefer fresh vegetables, chopped broccoli, bell peppers, mushrooms, or spinach are good choices.
Cheese
Shredded cheddar cheese adds flavor and gives the casserole a delicious melted topping.
You can substitute Monterey Jack, mozzarella, Colby, or a combination of cheeses.
Seasonings
Keep the seasoning simple with garlic powder, onion powder, black pepper, and a little dried parsley.
Depending on how your leftover chicken was seasoned, you can adjust everything to taste.
Easy Leftover Chicken and Rice Casserole Recipe
Ingredients
- 2 cups cooked leftover chicken, shredded or chopped
- 3 cups cooked rice
- 1 can cream of chicken soup
- 1/2 cup milk
- 1 cup frozen mixed vegetables
- 1 cup shredded cheddar cheese
- 1/2 teaspoon garlic powder
- 1/2 teaspoon onion powder
- 1/4 teaspoon black pepper
- 1/2 teaspoon dried parsley
- 1 tablespoon butter or cooking spray for the baking dish
Instructions
1. Preheat the Oven
Preheat your oven to 375°F (190°C).
Lightly grease a medium-sized casserole or baking dish with butter or cooking spray.
2. Prepare the Creamy Mixture
In a large mixing bowl, combine the cream of chicken soup and milk. Stir until smooth.
Add the garlic powder, onion powder, black pepper, and dried parsley.
Taste the mixture if desired and adjust the seasoning. Remember that canned soup and leftover chicken can already contain salt.
3. Add the Chicken and Rice
Add the cooked chicken and cooked rice to the bowl.
Add the frozen vegetables and about half of the shredded cheese.
Gently stir everything together until the rice, chicken, vegetables, and creamy sauce are evenly distributed.
Try not to mash the rice while mixing.
4. Transfer to the Baking Dish
Spoon the mixture into the prepared baking dish.
Spread it into an even layer using the back of a spoon or spatula.
Sprinkle the remaining cheese evenly over the top.
5. Bake
Cover the casserole loosely with aluminum foil and bake for about 20 minutes.
Remove the foil and continue baking for another 10 to 15 minutes, or until the casserole is hot throughout and the cheese is melted and lightly golden.
6. Rest and Serve
Allow the casserole to rest for about 5 minutes before serving.
This short resting time helps the sauce settle and makes the casserole easier to serve.
How to Keep the Casserole From Becoming Dry
One of the most common problems with leftover chicken and rice casserole is dryness.
Because both chicken and rice are already cooked, they can lose additional moisture during baking.
The easiest way to avoid this is to make sure there is enough creamy sauce in the mixture. Do not use significantly more rice than the recipe calls for without increasing the sauce as well.
Covering the casserole for the first part of baking also helps trap steam and moisture.
Another useful trick is to avoid overbaking. Once the casserole is hot and the cheese is melted, there is usually no reason to leave it in the oven much longer.
If your leftover chicken is particularly dry, you can also add a few tablespoons of extra milk or chicken broth to the mixture.
What Kind of Chicken Can You Use?
Almost any fully cooked chicken can work in this recipe.
Rotisserie chicken: Probably the easiest option. Remove the skin and bones, then shred or chop the meat.
Roasted chicken: Leftover roasted chicken adds plenty of flavor.
Baked chicken breast: Chicken breast works well, although it can be slightly drier than dark meat.
Chicken thighs: These are naturally juicy and can make the casserole especially flavorful.
Grilled chicken: Grilled chicken can add a subtle smoky flavor to the casserole.
If your chicken contains bones or skin, remove them before adding the meat to the casserole.
What Rice Works Best?
This recipe is forgiving when it comes to rice.
White long-grain rice is a simple choice, but basmati rice can add a pleasant aroma. Brown rice gives the casserole a heartier texture and slightly nutty flavor.
You can also use leftover jasmine rice if that is what you have.
The important thing is that the rice should already be cooked before it goes into the casserole.
Freshly cooked rice can work too, but allow it to cool slightly before mixing it with the other ingredients.
Can You Use Frozen Vegetables?
Absolutely.
Frozen vegetables are one of the easiest ways to make this recipe even more convenient.
A standard frozen mixed vegetable blend containing peas, carrots, corn, and green beans works beautifully.
You generally do not need to thaw the vegetables first. They can be mixed directly into the casserole.
If using a large amount of frozen vegetables, keep in mind that they may add extra moisture. Avoid adding excessive quantities unless you also increase the creamy sauce.
Easy Vegetable Variations
You can change the vegetables according to what you have available.
Try adding:
- Broccoli
- Peas
- Carrots
- Corn
- Green beans
- Mushrooms
- Bell peppers
- Spinach
- Zucchini
Broccoli and mushrooms are particularly good with creamy chicken and rice.
If using fresh vegetables, chop them into small pieces so they cook evenly.
For harder vegetables such as carrots, consider partially cooking them before adding them to the casserole.
Ways to Change the Flavor
The basic recipe is delicious on its own, but you can easily create different versions.
For a garlic-herb casserole, add extra garlic powder, dried thyme, and parsley.
For a cheesy version, mix additional cheddar or Monterey Jack into the filling.
For a slightly spicy casserole, add a pinch of red pepper flakes or a small amount of diced jalapeño.
For a Mexican-inspired version, use cooked chicken, rice, corn, black beans, salsa, cumin, and shredded Monterey Jack cheese instead of the traditional creamy mixture.
For a broccoli chicken casserole, replace the mixed vegetables with broccoli and use cheddar cheese.
These variations make it easy to use whatever leftovers you have available.
Can You Make This Casserole Ahead of Time?
Yes, this is one of the best features of the recipe.
You can assemble the casserole several hours before dinner. Cover it and keep it refrigerated until you are ready to bake it.
Because the casserole starts cold, you may need to add some extra baking time.
Do not leave a prepared casserole sitting at room temperature for an extended period. Keep it refrigerated until it is ready to go into the oven.
If you are preparing it specifically for the next day, assemble it in a covered baking dish and refrigerate it overnight.
How to Store Leftover Casserole
Allow the casserole to cool and place leftovers in an airtight container.
Store the casserole in the refrigerator and use it within a few days.
For longer storage, you can freeze portions in freezer-safe containers.
When freezing, portioning the casserole into individual servings can make reheating much easier.
Label the container with the date so you know when it was stored.
How to Reheat Chicken and Rice Casserole
The microwave is the fastest option for individual servings.
Place a serving on a microwave-safe plate and cover it loosely. Heat until hot, stirring or checking the center as needed.
You can add a small splash of milk or chicken broth before reheating if the casserole seems dry.
For larger portions, reheating in the oven works well. Cover the casserole with foil and warm it at a moderate temperature until heated through.
Avoid repeatedly reheating the entire casserole. Instead, heat only the amount you plan to eat.
What to Serve With Chicken and Rice Casserole
Because this casserole contains protein, rice, vegetables, and a creamy sauce, it can be a complete meal by itself.
However, a simple side dish can make dinner feel more complete.
A crisp green salad is a refreshing contrast to the creamy casserole.
Steamed broccoli, green beans, or roasted vegetables are also excellent choices.
You can serve it with warm dinner rolls or crusty bread if you want something extra.
For a lighter meal, simply serve a small salad alongside a scoop of casserole.
Tips for Making the Best Leftover Chicken and Rice Casserole
A few simple techniques can make a noticeable difference.
Use flavorful chicken. Leftover roasted or rotisserie chicken gives the casserole a deeper flavor than plain boiled chicken.
Do not overbake. The chicken and rice are already cooked, so the main goal is to heat everything through.
Taste before adding salt. Cream soups, cheese, and cooked chicken can already be salty.
Use enough sauce. A creamy casserole should not be dry or crumbly.
Spread the cheese evenly. This helps create a golden, cheesy topping.
Let it rest. Five minutes after baking makes the casserole easier to scoop and serve.
Frequently Asked Questions
Can I make leftover chicken and rice casserole without cream of chicken soup?
Yes. You can make a simple homemade white sauce using butter, flour, milk, and chicken broth. This is useful if you prefer not to use canned soup.
Can I use uncooked rice?
This particular recipe is designed for cooked rice. Uncooked rice requires additional liquid and a different cooking method because it needs time to absorb water and cook properly.
Can I use brown rice?
Yes. Cooked brown rice works well and gives the casserole a slightly heartier texture.
Can I use leftover turkey instead of chicken?
Definitely. Cooked turkey is an excellent substitute and can turn holiday leftovers into a completely different meal.
Can I add cheese inside the casserole?
Yes. Mixing cheese into the filling creates a cheesier texture, while adding cheese only to the top gives you a more noticeable melted topping. Using both is even better if you love cheesy casseroles.
Why did my casserole turn out dry?
The most common reasons are too much rice, not enough sauce, or overbaking. Add enough creamy mixture to coat the rice and chicken, cover the casserole during the first part of baking, and remove it from the oven once it is heated through.
A Great Way to Use Leftovers
One of the best things about an easy leftover chicken and rice casserole is that it does not feel like a meal made from leftovers. The creamy sauce, melted cheese, vegetables, and seasonings transform yesterday’s chicken and rice into something warm and comforting.

Have one cup of chicken left? Make a smaller casserole.
Have a lot of leftover rice after dinner? Add more vegetables and chicken and increase the sauce accordingly.
