Cook rice using chicken broth in place of water. Set aside.
Preheat oven to 375°F and lightly grease a 9x13-inch baking dish.
In a large bowl, combine cooked rice, red beans, creamy Creole beans, and sliced sausage. Stir until well mixed.
Pour the mixture into the prepared baking dish and spread evenly.
In a separate bowl, prepare the cornbread mix according to the instructions on the box.
Pour the cornbread batter over the rice and bean mixture, spreading it evenly.
Bake for 30–35 minutes or until the cornbread is golden and fully baked through.
Let rest for 5–10 minutes before serving. Enjoy!
