Preheat the oven to 375F. Lightly grease a 9x11 casserole dish with nonstick cooking spray.
Cut the rotisserie chicken to separate meat from bones and skin. Shred the meat into bite size pieces using two forks. You will need about 6 cups of shredded chicken for the recipe (it’s okay if it’s a little more or less).
In a large bowl, mix together 1 cup uncooked minute rice with the 1 ½ cups barbecue sauce (It’s important for rice to be fully coated to properly cook).
Add in the 6 cups shredded cooked chicken and mix until evenly coated.
Now add 1 cup black beans, 1 cup frozen corn, 1 cup chopped yellow onion, and 1 cup chopped green onion to the bowl and mix together.
Spread this mixture into an even layer in the casserole dish. Cover the dish with foil and bake for 30 minutes.
After 30 minutes, remove the foil and sprinkle 1 cup cheddar cheese and 1 cup mozzarella cheese over top. Bake an additional 10 minutes until cheese is melted. Serve immediately.
Recipe Notes:
Leftovers can be stored in the fridge in airtight container for up to 1 week or freezer for up to 3 months. Shredded rotisserie chicken or pre-cooked chicken can be used in replacement. You will need about 6 cups worth to make the casserole.
