This hearty soup will delight you with its creaminess that comes from cashews and cauliflower. Snuggle up on a cold day with a warming bowl.


  • 1 cup raw, unsalted cashews, soaked at least 4 hours, and drained
  • 8 cups of water, divided
  • 1 tablespoon of olive oil
  • 1 cup of diced yellow onion
  • 1 medium head cauliflower, leaves removed, cored, and cut into medium chunks (about 3 cups)
  • 3 medium stalks of broccoli, separated into bite-sized florets (about 45 cups) and peeled stems cut into medium chunks (about 12 cups)
  • 1 teaspoon of dried marjoram
  • 1 clove of garlic, minced
  • 1 tablespoon of salt
  • ¼ teaspoon of freshly ground black pepper


  1. In a blender, process cashews and 1 cup water to make a completely smooth cashew cream.
  2. Heat a large stock pot over medium-high heat and add oil. Sauté onion, cauliflower, broccoli stems only, and marjoram for 5 minutes. Stir in garlic and cook for 2 minutes more. Add remaining 7 cups water, cashew cream, and salt. Bring to a boil, then lower to medium heat, cover, and cook until vegetables are very soft, approximately 20 minutes.
  3. Using an immersion blender or carefully in 2-3 batches using a standard blender, purée soup base until completely smooth. Add broccoli florets and cook over medium heat for 5-7 minutes until broccoli is bright green and tender. Add pepper to taste and serve hot.


  • This soup is exceptionally versatile. If broccoli isn’t your favorite, feel free to substitute different veggies instead, like potatoes, mushrooms, asparagus, or corn.
