Cooking Time



For the Mash:

  • 2 medium sweet potatoes, diced
  • 1 yellow or white onion
  • 1 whole head of garlic
  • 1 tablespoon of tahini
  • 2 cups water, more or less to your desired consistency
  • 1/2-1 teaspoon turmeric
  • Celtic sea salt and black pepper, to taste

For the Cashew Cream:

  • 1 cup raw cashews, soaked in water overnight or for about 15 minutes
  • 1 tablespoon apple cider vinegar
  • 1 tablespoon fresh lemon juice
  • 1/2 teaspoon Celtic sea salt
  • 2 tablespoons coconut oil, melted

For the Optional Toppings:

  • Chia seeds
  • Sesame seeds
  • Sunflower seeds
  • Chives
  • Chili flakes
  • Green onions, sliced


  1. Drain and rinse the cashews, then place in a food processor and process for about 4 minutes, until a paste has formed. Add the vinegar, lemon juice, and salt, and process for 2-3 minutes longer into a smooth cream. While the machine is still running, add the coconut oil, and process shortly to blend. Scoop the cashew cream into a little bowl, set aside to serve when the soup is ready.
  2. Preheat your oven to 440°F.
  3. Peel and dice the sweet potato, peel the onion and cut into wedges. Divide the garlic head in half.and put the sweet potato, onion, and garlic on a parchment paper-lined baking sheet. Season with salt and pepper.
  4. Roast until the vegetables start to brown and the sweet potato has softened, about 15-20 minutes.
  5. Once the garlic is cool enough to handle, remove the skin. Transfer the roasted vegetables and garlic to a pot. Add water and turmeric to the pan.
  6. Bring to a boil, then remove from the heat. Add tahini and using an immersion blender, mix/blend the mash until smooth. Add a tablespoon of cashew cream (or more if you wish). You can also add the cream when serving. Add more water, if you prefer a thick soup instead of a mash. And optionally, add more salt and/or black pepper.
  7. Any leftover cashew cream will stay good in the refrigerator for up to a week (make sure to cover it).
