  • 1-2 tablespoons olive oil
  • 2 small onions chopped
  • 2 small zucchinis cut into small cubes
  • 3-4 cloves garlic minced
  • 1 teaspoon minced ginger
  • 400 g purple sweet potatoes baked, peeled and roughly chopped
  • 500-550 ml water
  • 2 tablespoons toasted sesame seeds optional
  • salt to taste
  • ginger powder to taste

Cashew cream

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


How to bake 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

  • Drain cashews well and put them into a high-speed blender. Add 200 ml water and blend on high speed until smooth.


  • Heat 1-2 tablespoons of olive oil in a large pot over medium heat. Add chopped onion, and zucchini and cook for about 4-5 minutes. Stir in minced garlic and ginger and cook until fragrant, about 1 minute.
  • Add approx. 400 g purple sweet potatoes, cashew cream, and 500 ml water and bring the soup to a boil. Reduce heat to low-medium, season with salt and ginger, cover, and allow to simmer for about 15 minutes. Stir occasionally. Taste and adjust seasonings as needed.
  • When the soup is done, add 2 tablespoons toasted sesame seeds. Use the immersion blender to puree the soup completely.
  • Feel free to add more water if the soup is too thick to your liking and adjust seasonings accordingly.

Serving suggestion

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