In a large Dutch oven, heat oil over medium-high heat. Add sausage to pot. Cook, stirring frequently, until browned, about 5 minutes. Let drain on paper towels. Add onion, celery, pepper, and garlic to pot. Cook, stirring frequently, until vegetables begin to caramelize, about 15 minutes. Add beans, sausage, broth, ham hock, bay leaves, Creole seasoning, thyme, and pepper. Bring to a boil. Reduce heat to low, and simmer until beans are tender and liquid has thickened, about 2 hours.

Using the back of a wooden spoon, crush some of the beans against the side of the pot. Serve red beans over cooked white rice. Garnish with sliced green onion, if desired.
