This family favorite is the same recipe my grandmother used. Now with the magic of the slow cooker, I can spend 15 minutes putting it together, walk away for five hours, and come back to "soup's on." Finish it with more milk if you like your soup a bit thinner. —Judy Batson, Tampa, Florida


Test Kitchen tip
  • For a less chunky soup, puree in batches in a blender or food processor.
  • We used Coleman's prepared mustard when testing this recipe. If you can't find English mustard, horseradish mustard is a good substitute.
