Start by soaking the dried white beans overnight in a large bowl of water.

After soaking, drain and rinse the beans under cold water.

In a large pot, heat the olive oil over medium heat.

Add the diced onion, garlic, bell pepper, and celery; sauté until softened, about 5 minutes.

Stir in the Cajun seasoning and smoked paprika, cooking for another minute.

Add the soaked beans and vegetable broth to the pot, ensuring the beans are submerged.

Bring the mixture to a boil, then reduce to a simmer.

Cover and cook for 30-40 minutes, or until the beans are tender.

Once cooked, taste and add salt and pepper as needed.

Serve the Cajun White Beans hot, garnished with chopped green onions.
