Ingredients

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

To Serve

  • maple syrup
  • freshly ground black pepper
  • chopped fennel fronds
  • more toasted walnuts chopped

Instructions

  • Heat the olive oil in a large soup pot over medium. Add the chopped leeks and thyme. Stir and sauté the leeks until they are a bit soft, about 4 minutes. Add the chopped fennel and apples. Stir everything up a bit. Add the turmeric and stir to coat all of the vegetables evenly. Sauté the vegetables until the fennel is starting to soften, another 4 minutes. Add the walnuts and stir them in. Season the whole thing with salt and pepper. Add the vegetable stock and stir.
  • Cover the pot and bring to a boil. Simmer until all of the vegetables/apples are very soft, about 12-15 minutes. Remove the soup from the heat. Carefully blend the mixture in batches in an upright blender until totally smooth. Check the soup for seasoning and adjust accordingly.
  • Pour the puréed soup back into the pot. Bring the puréed fennel walnut soup to a boil and then serve hot with little drizzles of maple syrup, fresh black pepper, fennel fronds, and more toasted walnuts if you like.

Notes

  • This is a pretty simple soup! Of course, I always think homemade vegetable stock is ideal, but especially with a soup with limited ingredients like this one.
