  • 1 tablespoon olive oil
  • 2 onions chopped
  • 2 zucchinis chopped
  • 1 thumb-sized ginger minced
  • 400 g purple sweet potatoes baked, peeled and roughly chopped
  • 450-500 ml of water
  • 2 tablespoons toasted sesame seeds
  • salt
  • ginger powder optional

Cashew cream

  • 100 g cashews previously soaked in water for a couple of hours
  • 200 ml of water


Baked purple sweet potatoes

  • Preheat oven to 200°C.
  • Wash a couple of purple sweet potatoes well and pat them dry with a dishtowel.
  • Place on a baking sheet and put them in the oven to bake for 30-45 minutes depending on size.
  • Check at 30 minutes by inserting a fork into the center. They should be soft. If not, return to the oven and check again in 10 minutes. Let them cool down a bit before peeling. There should be about 400 g after you bake and peel them.

Cashew cream

  • Place drained cashews and 200 ml water into a high-powered blender and blend on high speed until smooth. Set aside.


  • In a large pot place 1 tablespoon of olive oil and chopped onions, and cook over low-medium heat for about 5 minutes until translucent. Add chopped zucchini and minced ginger and cook for another couple of minutes on low.
  • Add approx. 400 g purple sweet potatoes, cashew cream, and 450 ml water and bring the soup to a boil. Reduce the heat to low and simmer for about 15 minutes. Stir occasionally. Taste and adjust seasonings as needed.
  • When the soup is done, add 2 tablespoons toasted sesame seeds. You can use the immersion blender to puree the soup completely or you can transfer it into a blender and blend until smooth.
  • If the soup is too thick to your liking you can add more water.

Serving suggestion

  • Serve your soup in a bowl and garnish it with broccoli sprouts, thyme, and toasted sesame seeds.
