Rinse the dried beans in a colander and discard any broken beans or debris.
Place the beans in the crock pot and cover with several inches of cold water. Cover and soak overnight.
The next morning, drain and discard the soaking water. Return the beans to the crock pot.
Add the water or broth, minced garlic, onion powder, salt, and black pepper. Make sure the beans are covered by approximately 2 inches of liquid, adding additional water if needed.
Cover and cook on High for 3–4 hours, or until the beans are tender.
Drain any excess cooking liquid if desired. Serve warm.
Notes
For the best texture, cook the beans on High. You can also cook them on Low for 6–8 hours.To cook the beans without soaking them first, rinse and sort the beans, then cook on High for approximately 5–6 hours or until tender. Add additional liquid during cooking if needed to keep the beans covered.If using dried red kidney beans, boil them on the stovetop for at least 10 minutes before adding them to the slow cooker.
