Cook your white rice on the stovetop or in a rice cooker according to the package directions. Set aside.
In a large stockpot or Dutch oven, heat the avocado oil over medium heat. Add the diced onion, celery, green bell pepper, and chopped smoked sausage. Cook until the onion is translucent, the vegetables are softened, and the sausage is lightly browned.
Stir in the minced garlic and cook for about 30–60 seconds, just until fragrant (be careful not to burn it).
Add the drained white beans, chicken broth, bay leaves, and Creole seasoning. Stir well to combine.
Bring the mixture to a boil, then reduce the heat to low. Cover and simmer for about 20 minutes (or a little longer if you want the flavors to deepen more).
Remove the bay leaves and serve the white beans and sausage mixture over warm white rice.
