Ingredients
  

  • These ingredients are carefully measured to ensure proper texture and balanced flavor.
Main Ingredients
  • 1 ½ lbs chicken breasts cut into bite-sized pieces
  • 1 cup long-grain white rice uncooked
  • 1 cup chicken broth
  • 16 oz salsa mild or medium, based on preference
Vegetables & Beans
  • 1 cup cooked black beans drained and rinsed
  • 1 cup frozen corn
  • ½ cup onion finely chopped
  • 1 teaspoon garlic minced
Seasonings
  • ½ teaspoon chili powder
  • ½ teaspoon paprika
Cheese
  • 1 cup cheddar cheese shredded
  • Long-grain white rice works best for even cooking and fluffy texture.

Equipment

  • Large Baking Dish (9x13 inch recommended)
  • Medium saucepan
  • Cutting board
  • Sharp knife
  • Mixing bowl
  • Measuring cups and spoons
  • Aluminum foil
  • Using a deep baking dish helps prevent overflow as the rice cooks and expands.

Method
 

Step 1: Preheat the Oven
  1. Preheat your oven to 190°C (375°F). Lightly grease the baking dish and set aside.
Step 2: Prepare the Rice Base
  1. In a mixing bowl, combine the uncooked rice, chicken broth, and salsa. Stir well to evenly distribute the liquid.
Step 3: Add Vegetables and Beans
  1. Stir the black beans, frozen corn, chopped onion, and garlic into the rice mixture.
Step 4: Season the Chicken
  1. Place the chicken pieces in a separate bowl. Sprinkle with chili powder and paprika, tossing until evenly coated.
Step 5: Assemble the Casserole
  1. Spread the rice mixture evenly in the prepared baking dish. Arrange the seasoned chicken pieces on top, pressing them gently into the mixture.
Step 6: Cover and Bake
  1. Cover the baking dish tightly with aluminum foil. Bake for 40–45 minutes, until the rice is tender and the chicken is cooked through.
Step 7: Add Cheese
  1. Remove the foil and sprinkle the shredded cheddar cheese evenly over the top.
Step 8: Finish Baking
  1. Return the dish to the oven uncovered and bake for an additional 10–12 minutes, until the cheese is melted and lightly golden.
Step 9: Rest Before Serving
  1. Remove from the oven and let the casserole rest for 5–10 minutes before serving. This allows the flavors to settle and the texture to firm up.
