Ingredients

This recipe uses simple pantry and fridge staples to create a full, balanced meal.

• ½ cup finely diced onion
• 1 red bell pepper, diced
• 1 cup uncooked parboiled long-grain brown rice (or long-grain white rice)
• 3 tablespoons fajita seasoning (homemade or store-bought)
• ⅛ teaspoon cayenne pepper (optional)
• 1 cup frozen corn kernels
• 1 (14-ounce) can black beans, drained and rinsed
• 5 cups shredded chicken
• 3 cups reduced sodium chicken broth
• 1 (4-ounce) can mild green chilies
• 1 tablespoon olive oil
• 2 tablespoons tomato paste
• 1¼ cups shredded Monterey Jack cheese

Each ingredient plays a key role in building layers of flavor and texture. The rice absorbs the seasoned broth, the chicken provides protein and heartiness, the beans and corn add texture and sweetness, and the cheese creates a rich, melty topping.

Preparation Method

Step 1: Preheating and Preparing the Baking Dish

Begin by preheating your oven to 400°F (200°C). This temperature allows the rice to cook evenly while the flavors develop fully.

Lightly prepare a 9×13-inch baking dish. This size is ideal because it allows the ingredients to cook evenly without overcrowding.

Step 2: Building the Base Flavor

In the baking dish, add the diced onion, diced red bell pepper, uncooked rice, fajita seasoning, and cayenne pepper if you want a bit of heat.

Stir everything together thoroughly so that the rice grains are evenly coated with seasoning and the vegetables are well distributed.

This step is important because it ensures that the base of the casserole is flavorful from the very beginning, rather than relying only on the liquid or toppings.

Step 3: Preparing the Broth Mixture

In a separate bowl or large measuring cup, combine the chicken broth, green chilies, tomato paste, and olive oil.

Whisk until the tomato paste is fully dissolved and the mixture is smooth. This creates a rich, seasoned liquid that will cook the rice and infuse the entire casserole with flavor.

The green chilies add mild heat and depth, while the tomato paste provides a slightly tangy richness.

Step 4: Combining Everything in the Dish

Pour the broth mixture into the baking dish over the rice and vegetable mixture.

Stir well to ensure everything is evenly distributed and the rice is fully submerged in liquid.

Next, add the shredded chicken, black beans, and corn. Mix again until all ingredients are evenly combined throughout the dish.

At this stage, the casserole should look like a colorful, hearty mixture filled with vegetables, protein, and rice.

Step 5: Baking the Casserole

Cover the baking dish tightly with aluminum foil. This step is essential because it traps steam, allowing the rice to cook properly and absorb all the liquid.

Place the dish in the preheated oven and bake for 65 to 70 minutes.

During baking, the rice absorbs the seasoned broth, the chicken warms through, and all flavors meld together into a cohesive dish.

After the cooking time is complete, carefully remove the foil and check that the liquid has been absorbed and the rice is tender.

Step 6: Adding Cheese and Final Bake

Once the casserole is fully cooked, sprinkle the shredded Monterey Jack cheese evenly over the top.

Return the dish to the oven, uncovered, and bake for an additional 5 to 10 minutes.

During this final stage, the cheese melts and becomes slightly golden, forming a creamy and flavorful topping that enhances the entire dish.

Step 7: Resting and Serving

Remove the casserole from the oven and let it rest for 5 to 10 minutes before serving.

This resting period allows the dish to set slightly, making it easier to serve and helping the flavors settle.

Serve warm, optionally topped with fresh cilantro, sliced green onions, salsa, or diced avocado for added freshness.

Tips for Best Results

• Stir well before baking to ensure even cooking.
• Keep the dish tightly covered so the rice cooks properly.
• Use warm broth for slightly faster absorption.
• Do not skip resting time before serving.
• Adjust seasoning based on spice preference.

These small details help ensure a perfectly cooked casserole every time.
