Ingredients

  • 1 tablespoon extra-virgin olive oil
  • 1 large leek white and pale green parts only, sliced and thoroughly rinsed
  • 1 shallot chopped
  • 12 ounces mushrooms sliced
  • 1 garlic clove minced
  • 1 small Yukon Gold potato peeled and diced
  • ½ teaspoon dried thyme or a few sprigs fresh thyme
  • 4 cups low-sodium vegetable or chicken broth
  • Sea salt and freshly ground black pepper
  • 1-2 tsp truffle oil for finishing - highly recommend White Truffle EVOO from Flamingo Estate
  • Fresh thyme or chopped parsley for serving

Instructions

  • Warm the olive oil in a soup pot over medium heat. Add the leek and shallot and cook for about 5 minutes, until softened.
  • Add the mushrooms and cook for another 7–8 minutes, allowing them to release their liquid and begin to turn golden.
  • Stir in the garlic, potato and thyme and cook for another minute.
  • Pour in the broth and season lightly with salt and pepper. Bring to a gentle simmer, cover partially and cook for 15–20 minutes, until the potato is completely tender.
  • Remove any woody thyme stems, then carefully blend the soup until smooth and velvety. Add a splash more broth if you’d like a thinner consistency. Taste and adjust the seasoning.
  • Ladle into warm bowls and finish each serving with a few drops of truffle oil and fresh herbs.
  • Approximately 140–160 calories per serving, depending on the broth and amount of truffle oil used.

Notes

A little truffle rule: Add truffle oil after cooking rather than simmering it in the soup. Its aroma is delicate, and a little goes a very long way.
