Start by sorting the Camellia red beans. Spread them out and remove any small stones or damaged beans. Rinse well under cold water.
Soak the beans overnight in plenty of water. This helps them cook evenly and develop that creamy texture. If you’re short on time, you can use a quick soak method, but overnight soaking gives the best result.
Drain the beans and set them aside.
In a large pot or Dutch oven, heat the olive oil over medium heat. Add the sliced sausage and cook until lightly browned. Remove the sausage and set aside, leaving the flavorful oil behind.
Add the onion, bell pepper, and celery to the pot. Cook for about 5 to 7 minutes, stirring often, until soft and fragrant. Add the garlic and cook for another 30 seconds.
Return the sausage to the pot. Add the soaked beans, water or broth, ham hock, bay leaves, thyme, smoked paprika, black pepper, and white pepper. Stir well.
Bring everything to a gentle boil, then reduce heat to low. Cover partially and let it simmer for about 2 to 2½ hours, stirring occasionally. The beans should become tender and creamy.
Once the beans are soft, remove the ham hock and bay leaves. Mash a small portion of the beans against the side of the pot to thicken the mixture. Taste and adjust salt and hot sauce as needed.
Serve the beans over hot white rice and garnish with green onions.
