You don’t need to soak your beans before cooking. Just dump everything into the Crock Pot and add plenty of water (at least a couple of inches above the beans).
Cover and cook on low for 6 hours. The beans are done when they are tender and starting to split.
Taste and adjust seasonings if desired. Scoop beans out into a big bowl, keeping the cooking liquid in the pot.
Mash the beans, adding cooking liquid as needed, until they’re your favorite consistency. My crew likes them lumpy, so I use an old-fashioned potato masher. If you prefer a smoother consistency, use an immersion blender.
