Place the thawed chicken breasts into the slow cooker. Ensure that the chicken is not frozen to maintain proper cooking times.
Add Liquid and Seasonings
Pour the chicken broth over the chicken. Add olive oil, onion powder, garlic powder, chili powder, cumin, diced tomatoes, salt, and black pepper. Stir gently to incorporate the seasonings into the liquid.
Cook the Chicken
Cover and cook on the low setting for approximately 4 hours, or until the chicken reaches an internal temperature of 165°F (74°C).
Shred and Remove the Chicken
Once fully cooked, remove the chicken from the slow cooker and set aside on a plate for shredding.
Cook the Rice and Beans
Adjust the slow cooker to the high setting. Stir in the black beans and brown rice. Continue cooking for 30–45 minutes, or until the rice is fully cooked and tender.
Recombine Ingredients
Shred the chicken using two forks and return it to the slow cooker. Stir gently to combine with the rice and beans.
Add Cheese and Serve
Sprinkle shredded Colby Jack cheese evenly over the mixture. Cover for several minutes until the cheese is fully melted. Serve immediately with desired toppings such as diced green onions, fresh tomatoes, avocado slices, guacamole, or sour cream.
