1 tablespoon olive oil – Enhances moisture and flavor distribution.
2 tablespoons tomato paste – Concentrates tomato richness.

Main Ingredients

1 cup uncooked parboiled long-grain brown rice or long-grain white rice – Forms the hearty base; parboiled ensures even cooking.
5 cups cooked, shredded chicken – Provides lean protein and substance.
3 cups reduced-sodium chicken broth – Hydrates rice and infuses savory flavor.
1 cup frozen corn kernels – Adds sweetness and texture contrast.
1¼ cups shredded Monterey Jack cheese – Melts smoothly over the top for creamy finish.

Step-by-Step Instructions

Preheat and Prepare

Preheat oven to 400°F (200°C). Lightly grease a 9×13-inch baking dish to prevent sticking.

Combine Dry Ingredients

In the baking dish, mix diced onion, bell pepper, uncooked rice, fajita seasoning, and cayenne pepper until evenly distributed.

Prepare the Liquid Mixture

In a separate bowl, whisk together chicken broth, green chilies (with juices), tomato paste, and olive oil until fully combined and smooth.

Combine Everything

Pour the liquid mixture over the rice mixture and stir. Add shredded chicken, black beans, and corn, mixing thoroughly to distribute evenly.

Bake Covered

Cover the baking dish tightly with aluminum foil and bake for 65–70 minutes, or until the rice is tender and liquid is fully absorbed.

Add the Cheese

Remove foil and sprinkle Monterey Jack evenly over the top. Return to oven uncovered for 5–10 minutes until cheese is melted and lightly golden.

Rest Before Serving

Allow casserole to rest for 5–10 minutes to set before serving.
