Why I Love This Recipe
This is the kind of dinner I like to make when I want one dish that feels complete. The first time I put this combination together, I loved how the rice soaked up the tomato juices and chicken broth while the cheese melted over everything.
It also has plenty of texture. The corn gives it little sweet bites. Black beans make it hearty. The chicken stays tender, and the melted cheese brings everything together.
- Everything bakes in one casserole dish.
- It uses easy-to-find ingredients.
- The rice cooks right in the casserole.

What You’ll Need
- 2 cups cooked shredded chicken
- 1 cup uncooked long-grain white rice
- 1 can (15 ounces) black beans, drained and rinsed
- 1 cup frozen corn, thawed
- 1 can (10 ounces) diced tomatoes with green chiles, undrained
- 1/2 cup diced onion
- 1/2 cup diced green bell pepper
- 2 cups low-sodium chicken broth
- 1 tablespoon olive oil
- 2 teaspoons chili powder
- 1 teaspoon ground cumin
- 1 teaspoon garlic powder
- 1/2 teaspoon smoked paprika
- 1/2 teaspoon salt
- 1 cup shredded cheddar cheese
- 1 cup shredded Monterey Jack cheese
- 2 tablespoons chopped fresh cilantro
- 2 green onions, thinly sliced
Recipe and Instructions
Step 1: Prep the Oven and Dish
Heat the oven to 375°F (190°C). Coat the inside of a 9×13-inch casserole dish with 1 tablespoon olive oil. Spread the oil across the bottom and sides so the rice does not stick.
Step 2: Build the Rice Mixture
Add 1 cup uncooked long-grain white rice, 1 can (15 ounces) drained and rinsed black beans, 1 cup thawed corn, 1 can (10 ounces) diced tomatoes with green chiles including all the liquid, 1/2 cup diced onion, and 1/2 cup diced green bell pepper to the prepared casserole dish.
Sprinkle in 2 teaspoons chili powder, 1 teaspoon ground cumin, 1 teaspoon garlic powder, 1/2 teaspoon smoked paprika, and 1/2 teaspoon salt.
Pour in 2 cups low-sodium chicken broth. Stir very well so the rice and seasonings are spread evenly through the liquid.
Step 3: Add the Chicken
Spread 2 cups cooked shredded chicken evenly over the rice mixture. Press the chicken down lightly so some of it touches the liquid. Do not stir it deeply into the rice.
Cover the casserole dish tightly with aluminum foil.
Step 4: Bake Until the Rice Is Tender
Place the tightly covered casserole in the oven. Bake at 375°F (190°C) for 30 minutes.
Carefully remove the foil. Check a few grains of rice from the center. The rice should be almost tender and most of the broth should be absorbed. If the rice is still firm and the dish looks dry, add 2 to 4 tablespoons hot water, cover again, and bake for another 5 to 10 minutes.
Step 5: Add the Cheese
When the rice is tender, sprinkle 1 cup shredded cheddar cheese and 1 cup shredded Monterey Jack cheese evenly over the casserole.
Return the casserole to the oven uncovered and bake for 5 to 10 minutes, until the cheese is completely melted and bubbling around the edges.
Step 6: Garnish and Serve
Let the casserole rest for 5 minutes. Sprinkle 2 tablespoons chopped fresh cilantro and 2 thinly sliced green onions over the top.
Scoop portions into round bowls or onto round plates and serve warm.
Why This Recipe Works (Quick Science)
Rice needs both liquid and trapped steam to cook well. Covering the casserole tightly keeps that steam inside. This lets the rice slowly absorb the chicken broth and tomato juices.
The chicken is already cooked, so it only needs to heat through. Adding the cheese near the end keeps it soft and creamy instead of making it tough or oily.
Letting the casserole rest for 5 minutes also matters. The rice gets a few extra minutes to absorb moisture, and the casserole becomes easier to scoop.
Pro Tips
- Cover it tightly. Loose foil can let too much steam escape before the rice is cooked.
- Use long-grain white rice. Brown rice and instant rice need different amounts of liquid and cooking time.
- Do not drain the tomatoes. Their liquid helps cook the rice and adds flavor.
- Check the center. Rice around the edges may cook before rice in the middle.
- For a milder casserole, choose mild diced tomatoes with green chiles and mild chili powder.
Tools You’ll Need
- 9×13-inch casserole dish
- Aluminum foil
- Measuring cups
- Measuring spoons
- Liquid measuring cup
- Can opener
- Colander
- Cutting board
- Chef’s knife
- Wooden spoon
- Oven mitts
Substitutions and Variations
- Swap the shredded chicken for cooked shredded turkey.
- Use pepper Jack instead of Monterey Jack for more heat.
- Use pinto beans instead of black beans.
- Add a small diced jalapeño if you want more spice.
- Leave out cilantro if you do not enjoy its flavor.
- Add a squeeze of fresh lime juice after baking for a brighter flavor.
- For the most reliable rice texture, do not replace the long-grain white rice with brown or instant rice without also changing the liquid and cooking time.
Make-Ahead Tips
You can shred the chicken and chop the onion, bell pepper, cilantro, and green onions up to 2 days ahead. Keep everything covered in the refrigerator.
For the best rice texture, wait until you are ready to bake before mixing the uncooked rice with the broth and tomatoes.
Common Mistakes
- Using cooked rice: This recipe is designed for 1 cup of uncooked rice. Cooked rice can become mushy.
- Leaving the dish uncovered: The rice needs trapped steam during the first part of baking.
- Draining the tomatoes: Keep the tomato liquid because it is part of the cooking liquid.
- Using a different type of rice: Different rice can need very different cooking times.
- Adding cheese too early: A long baking time can dry out the cheese.
- Skipping the rest time: Five minutes of resting helps the casserole set.

Leftovers and Storage
Let leftovers cool, then place them in an airtight container. Store them in the refrigerator for up to 4 days.
Reheat individual portions in the microwave until hot throughout. Adding a teaspoon or two of water before reheating can help keep the rice moist.
For longer storage, freeze cooled portions in freezer-safe containers for up to 2 months. Thaw overnight in the refrigerator before reheating. The rice may be a little softer after freezing.
FAQ
Q: Can I use rotisserie chicken?
A: Yes. Rotisserie chicken works very well. Remove the skin and shred 2 cups of cooked chicken before measuring.
Q: Do I cook the rice first?
A: No. Use 1 cup of uncooked long-grain white rice. It cooks in the chicken broth and tomato liquid while the casserole bakes.
Q: Why is my rice still crunchy?
A: The casserole may have lost too much steam, or your oven may cook a little cooler. Add 2 to 4 tablespoons of hot water, cover the dish tightly, and bake another 5 to 10 minutes.
Q: Can I make it spicy?
A: Yes. Use hot diced tomatoes with green chiles, pepper Jack cheese, or add diced jalapeño.
Q: Can I leave out the beans?
A: Yes. You can leave them out. The casserole will be a little less hearty, but the cooking method stays the same.
Q: How do I know when it is done?
A: Check the rice in the center of the casserole. It should be tender, the liquid should be mostly absorbed, the chicken should be hot, and the cheese should be fully melted.
