Ingredients and Preparation

Here’s what you’ll need to make this flavorful casserole:

Main Ingredients

• 1 ½ pounds boneless, skinless chicken breasts – chopped into bite-sized pieces for even cooking
• 1 cup white rice – uncooked; jasmine or basmati rice also works well
• 1 cup canned black beans – drained and rinsed
• 1 cup frozen corn – no need to thaw
• 1 bell pepper (any color) – diced
• 1 small red onion – finely chopped
• 1 10 oz can diced tomatoes with green chilies – adds spice and moisture
• 1 cup shredded cheddar cheese – or a mix of cheddar and Monterey Jack
• 1 cup low-sodium chicken broth – for cooking the rice directly in the dish
• 1 tablespoon olive oil – to coat the baking dish and help blend ingredients

Spices and Seasonings

• 1 teaspoon ground cumin
• 1 teaspoon chili powder
• 1 teaspoon garlic powder
• ½ teaspoon paprika
• Salt and black pepper to taste

Optional Toppings

• Sliced green onions
• Chopped cilantro
• Greek yogurt or sour cream
• Diced avocado

Preparation Steps Before Baking

1. Preheat the oven to 375°F (190°C).
2. Lightly grease a 9×13-inch baking dish with olive oil or cooking spray.
3. Rinse the rice under cold water to remove excess starch. This helps keep it from becoming too sticky in the casserole.
4. Dice all vegetables and chop chicken into uniform pieces to ensure even cooking.

Step-by-Step Instructions

1. Layer the base
   • In the greased baking dish, combine the uncooked rice, black beans, corn, diced bell pepper, red onion, and diced tomatoes with green chilies. Mix them together with a spoon to evenly distribute.
2. Add the chicken
   • Scatter the diced chicken evenly over the vegetable and rice mixture. There’s no need to pre-cook the chicken, as it will bake thoroughly in the oven.
3. Season generously
   • In a small bowl, stir together the cumin, chili powder, garlic powder, paprika, salt, and pepper. Sprinkle the spice blend over the chicken and rice mixture, making sure everything is evenly coated.
4. Pour in the broth
   • Slowly pour the chicken broth over the entire casserole. Gently stir the ingredients in the dish so the broth can start soaking into the rice.
5. Bake uncovered
   • Cover the dish tightly with aluminum foil and bake for 50–55 minutes. The rice should be tender, and the chicken fully cooked.
6. Remove foil and add cheese
   • After baking, remove the foil and sprinkle the shredded cheese on top. Return to the oven, uncovered, and bake for an additional 5–10 minutes until the cheese is melted and bubbly.
7. Let it rest
   • Remove the dish from the oven and let it sit for 5 minutes before serving. This allows the casserole to set and makes it easier to serve.
8. Garnish and serve
   • Add optional toppings like chopped cilantro, sliced green onions, or a dollop of Greek yogurt. Serve warm.

Beginner Tips and Notes

• Use pre-cooked chicken if you have leftovers. Simply mix it in with the rice and reduce the cooking time by about 10 minutes.
• Drain wet ingredients like canned tomatoes and beans well to avoid excess liquid.
• Adjust the spice level by using mild or hot diced tomatoes with chilies. You can also add cayenne pepper for more heat.
• Use brown rice for a more nutritious option, but note that it may require extra broth and a longer baking time.
• Make it vegetarian by omitting the chicken and adding extra beans or a plant-based protein like tofu or lentils.
• Double the recipe and freeze half for future meals. This casserole freezes well—just let it cool completely and store it in an airtight container.
• Test the rice for doneness before removing from the oven. If it’s still a little firm, cover again and bake for another 5–10 minutes with a splash of broth.
• Shred your own cheese for better melt quality. Pre-shredded cheese contains anti-caking agents that can affect texture.

Serving Suggestions

This casserole is hearty enough to serve as a complete meal, but you can enhance it with simple sides or accompaniments:

• Serve with a side salad with lime vinaigrette to add freshness and a crunchy contrast.
• Add tortilla chips or warm corn tortillas on the side for scooping or wrapping.
• Top with avocado slices or guacamole to add creaminess and healthy fats.
• Offer Greek yogurt or light sour cream as a cooling contrast to the spices.
• Make it a bowl by serving the casserole over chopped romaine with fresh lime juice.
• Pair with roasted vegetables like zucchini or sweet potatoes to boost the meal’s nutrition profile.
• Turn leftovers into wraps by scooping the casserole into a large tortilla with a bit of extra cheese and rolling it up for a delicious lunch the next day.

• Try different vegetables like zucchini, cherry tomatoes, or spinach to customize the flavor.

• Ask yourself: What’s your favorite way to add heat—jalapeños, chili flakes, or chipotle?
• Get kids involved by letting them sprinkle the cheese or help mix ingredients before baking.
• Share your variation with friends or online cooking groups—what did you add or swap to make it yours?
• Plan for leftovers by storing single portions in containers for easy grab-and-go lunches.
• Invite feedback if cooking for family or roommates—did they like the spice level or want more cheese next time?
• Pair with drinks like sparkling water with lime, iced tea, or a light beer for a casual dinner.
