How To Make slow cooker french onion soup

    After 8 hours of cooking, begin checking onions for doneness. Cooking may take up to 12 hours since slow cookers vary, but onions can burn quickly, so check onions every half hour until desired doneness is achieved.

    Once onions are done, combine chicken broth and remaining beef broth in a saucepan and bring to a boil.

    Pour boiled broths over onions. Taste and season with additional salt and pepperif needed (if not serving immediately,reduce slow cooker to warm and reserve until ready to serve).

    Divide soup evenly into oven safe serving vessels (crocks, mugs, etc). Top each with toast slices, divide shredded swiss cheese among vessels and top each with a slice ortwo of sliced swiss (enough to slightly overlap the edges of the vessel).
  • 12
    Place the soup underthe broilerfor 5-7 minutes, or until the cheese is bubbly and slightly browned. Cool for a couple minutes before serving.
