Don’t worry if you forget to soak the beans the night before! Beans can be cooked for longer from dried,
or soaked for 3 hours on the counter in warm water.
In a large mixing bowl, cover the dried pinto beans with enough water for the beans to expand and double in size. Let it sit overnight.
The next day, strain and rinse the pinto beans. Add to the slow cooker pot with the quartered onion, smashed garlic cloves, bay leaves, salt, and 6 cups of water.
Place the lid on top and Slow Cook on High for 4 Hours 30 Minutes, or on Low for 9 Hours, stirring occasionally.
After the time is done, turn on the Sauté function at 320°F for 30 Minutes to reduce the liquid. Serve warm or cold as a side or in soups, stews, or bowls.
