Soak the beans: Place the dried beans in a large bowl and cover with cold water. Soak for 12-24 hours. If you are in a hurry, most bags of beans have a “speed-soak” method listed on the package.
Set a large 6-8 quart sauce pot over medium heat. Add the bacon. Stir and brown for 3-5 minutes. Add the onion, carrots, celery, garlic, thyme, rosemary, and bay leaves. Sauté for 5 minutes to soften.
Drain the beans. Then pour the beans into the pot. Add in the chicken base and water. Stir well.
Cover and simmer for 30-45 minutes, until the butter beans are soft.
Taste, then salt and pepper as needed.
