Slow Cooker Refried Beans are about as easy as a slow cooker / crock pot recipe can get! The flavor of these refried beans is so much better than the canned stuff! Just dump in the pot and go!
Rinse and sort the pinto beans. Add to the slow cooker.
Add all remaining ingredients to the slow cooker and stir.
Put the lid on and cook on High for 5 hours, or Low for 8 hours.
When done, use an immersion blender to puree the beans. You could use a potato masher if you like the beans coarser.
Garnish as desired. Some options are pepitas, cilantro, sour cream, lime, Cotija or other cheese, avocado, or salsa.
