Soak the dried butter beans in water overnight.

Drain and rinse the soaked beans in a colander.

In a pot, heat olive oil over medium heat.

Add chopped onion and sauté until translucent, about 5 minutes.

Stir in minced garlic and cook for another minute.

Add the soaked butter beans, water, vegetable broth, salt, pepper, and thyme to the pot.

Bring to a boil, then reduce heat and simmer for about 30 minutes, or until beans are tender.

Adjust seasoning as needed before serving.
