Vegan Cream of Broccoli Soup Recipe

Vegan Cream of Broccoli Soup Recipe

This cozy vegan broccoli cauliflower soup is made with healthy ingredients that would surprise some—like cream made from cashews rather than milk from a momma cow!

Chef Allison Rivers Samson shows how easy it is to transform plants into delicious, familiar dishes like this creamy broccoli soup. Enjoy!

The Wonders of Vegan Broccoli Cauliflower Soup

This hearty soup is not only delicious but also packs in a variety of health benefits. Here’s a closer look at what you’re getting with every bite:

  • Plant Protein – Cashews not only add a delicious creaminess to every dish you use them in but are super rich in protein! Just one ounce contains over 5 grams, making this creamy nut a mighty vegan protein source. 
  • Big Broccoli Benefits – Broccoli is the classic vegetable of vegetables. Nutritious, beautiful, and bulky, broccoli boasts a wide array of vitamins, iron, and fiber making it an obvious choice for maintaining a healthy diet.
  • Cauliflower Creaminess – Like broccoli, cauliflower is a nutritious, cruciferous vegetable belonging to the same family as cabbage, bok choy, and kale but what truly sets it apart is its creamy, luscious consistency. Cauliflower is perfect for making soup for this very reason!

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.
