01 - Preheat oven to 375°F. Lightly grease a 9x13-inch baking dish with cooking spray or a small amount of oil.
02 - In a large bowl, mix uncooked rice, diced onion, red bell pepper, corn, drained black beans, diced tomatoes with chilies including juices, chicken broth, cumin, smoked paprika, chili powder, garlic powder, salt, and pepper until well combined.
03 - Pour the rice and vegetable mixture evenly into the prepared baking dish, spreading it out to create an even layer.
04 - Nestle the cut chicken pieces into the rice mixture, distributing them evenly throughout the dish so they are partially submerged.
05 - Cover the baking dish tightly with aluminum foil. Bake for 35 minutes until the rice has absorbed most of the liquid and chicken is cooked through.
06 - Remove the foil and sprinkle shredded Mexican cheese evenly over the top. Return to the oven and bake uncovered for 10-15 minutes until the cheese is melted and bubbly.
07 - Let the dish rest for 5 minutes before serving to allow the flavors to settle. Serve garnished with fresh cilantro, sliced jalapeños, sour cream, and lime wedges if desired.
