Celery Root Soup

Celery Root Soup

Makes 6 generous servings.

This is a silky, nutritious soup that tastes rich without the addition of any cream.

People are always impressed with the elegance of this soup, and it is very simple to prepare.


  • 4 leeks
  • 2 medium celery roots, about 2 pounds
  • 2 tablespoons extra-virgin olive oil
  • 3 thyme sprigs, plus some for garnish
  • 5 ½ cups chicken broth
  • Kosher salt
  • Freshly ground black pepper


  1. Cut off and discard the roots and tough green leaves of the leeks. Cut the white part and light green part into small pieces. Place in a sieve and rinse thoroughly under cold running water to remove all the sand.
  2. Peel celery root carefully and remove all embedded dark spots. (This rough looking vegetable is a bit tricky to peel.)
  3. Cut into small pieces.
  4. Heat the oil in a medium saucepan with a cover, add the leeks and sauté covered for 5 minutes. Add the celery root, thyme and 5 cups of chicken broth. Bring to a boil over high heat. Lower the heat and cook covered for about 30 minutes, or until the vegetables are soft.
  5. Remove the thyme sprigs and discard. Puree in a Vitamix until smooth.
  6. Adjust the consistency with the reserved broth and season to taste with salt and pepper.
  7. Serve garnished with thyme petals.
