Creamy Celery Root Soup

Creamy Celery Root Soup

Don't be afraid of celery root because of its rugged exterior. The inside creams up for a beautiful velvety soup. With less starch than potatoes, and extra B vitamins you can't go wrong!



  • 3 tablespoons extra-virgin olive oil, plus more for garnish
  • 1 cup thinly chopped onion
  • 1 small celery root
  • 1 medium Yukon potato
  • 2 teaspoons kosher salt, plus more as needed
  • Freshly ground black pepper
  • 3 ½ cups water


Heat oil in a large saucepan with a tightfitting lid over medium-high heat until shimmering. Add onion and cook, stirring occasionally, until softened and translucent, about 15 minutes. Add celery root, potatoes, salt, and a pinch of pepper. Stir to coat vegetables with oil, add water, and bring to a boil. Cover, reduce heat to low, and simmer until vegetables just give way when pierced with a knife, about 20 to 25 minutes.

Remove 1 cup of liquid from the saucepan; set aside. Using a blender, purée the soup in batches until smooth, removing the small cap from the blender lid (the pour lid) and covering the space with a kitchen towel (this allows steam from the hot soup to escape and prevents the blender lid from popping off). Once blended, transfer the soup back to the saucepan and keep warm over low heat. If the soup is too thick, add the reserved liquid a little at a time until the soup reaches the desired consistency. Taste and season with additional salt and pepper as needed. To serve, drizzle with olive oil.
