Description

A creamy, vibrant soup combining the subtle sweetness of fennel and apple with the earthy warmth of turmeric and the crunch of toasted walnuts. This gluten-free, vegan recipe is perfect as a comforting main course or starter.


Ingredients

Scale

Soup

  • 2 tablespoons olive oil
  • 3 leeks, white and light green parts chopped (discard green tops or use them for stock)
  • 2 teaspoons fresh thyme leaves, chopped
  • 1 medium fennel bulb, cored and chopped
  • 1 medium apple, peeled, cored and chopped
  • 1 teaspoon ground turmeric
  • ½ cup walnut halves, toasted
  • Sea salt and ground black pepper, to taste
  • 4 cups vegetable stock


Instructions

  1. Prepare the base: Heat the olive oil in a large soup pot over medium heat. Add the chopped leeks and thyme. Stir and sauté the leeks until they are slightly softened, about 4 minutes.
  2. Add vegetables and spices: Add the chopped fennel and apple to the pot. Stir to combine. Sprinkle in the ground turmeric and stir thoroughly to evenly coat all the vegetables with the spice.
  3. Sauté until softened: Continue cooking the vegetables, stirring occasionally, until the fennel starts to soften, about 4 minutes more.
  4. Incorporate walnuts and season: Stir in the toasted walnut halves. Season the mixture generously with sea salt and ground black pepper to taste.
  5. Add stock and simmer: Pour in the vegetable stock and stir well. Cover the pot and bring the mixture to a boil. Reduce heat and let it simmer until all vegetables and apples are very soft, approximately 15 minutes.
  6. Blend the soup: Remove the pot from heat. Carefully transfer the soup in batches to an upright blender and blend until completely smooth.
  7. Adjust seasoning and reheat: Pour the puréed soup back into the pot. Bring it to a boil again, check seasoning, and adjust salt and pepper as needed.
  8. Serve: Ladle the hot soup into bowls. Optionally, drizzle with maple syrup, add fresh cracked black pepper, garnish with fennel fronds, and sprinkle extra toasted walnuts for crunch.

Notes

  • Homemade vegetable stock enhances the flavor but commercial stock works well too.
  • Celery can be used as a substitute for fennel if unavailable.
  • Pecans are a great alternative to walnuts, offering a slightly different yet complementary flavor.
  • For a richer soup, swirl in a dollop of coconut cream or plant-based yogurt before serving.
  • Use a high-quality blender to achieve a perfectly smooth texture.
