  • Total Time: up to 10 hours
  • Yield: 8-10 cups 1x


  • 15 bean soup mix - dried beans, 20 ounces
  • 8 cups vegetable broth
  • 1 cup white or yellow onion - chopped 
  • 2 cups carrots - chopped 
  • 1 cup celery - chopped

  1. Soak your dried 15 bean soup mix overnight.  Open the package of beans, discard the seasoning packet (if included) and pour the dried beans into a large bowl or stock pot.  Sort through the beans and discard any debris.  Cover the beans with about 10 cups of water and let sit overnight in the refrigerator.

  3. Add the rest of the soup ingredients to your slow cooker.  This includes the vegetable broth, onion, carrots, celery, garlic, tomato paste, Worcestershire sauce, parmesan cheese rind, dried thyme, bay leaves, salt and pepper. 
  4. Cook your 15 bean soup on low for 8-10 hours or on high for 5-6 hours.
  5. When the soup has finished cooking, remove the bay leaves and the parmesan cheese rind.  Serve bowls of soup topped with fresh parsley, grated parmesan cheese or crispy bacon!  Enjoy!
