  • 4 large russet potatoes peeled and cut into 1 ½ inch chunks
  • 2 large celery roots peeled and cut into 1 inch chunks
  • ½ onion quartered
  • 4 cups water
  • 4 cups whole milk
  • 1 tablespoon coarse salt plus more to taste
  • 8 tablespoons 1 stick unsalted butter
  • Freshly ground pepper


  • Place potatoes, celery root and onion a large pot and cover with water and milk.  Add salt. Bring to a boil over medium-high heat. Reduce heat to medium and continue to cook until potatoes and celery root are very tender, about 30 minutes.  Drain and discard cooking liquid.
  • Transfer half of the potatoes and celery root to a food processor along with 4 tablespoons of butter.  Process until smooth and transfer to a serving bowl. Repeat with remaining potatoes, celery root and butter.  Season to taste with salt and pepper. Serve. (Puree can be prepared a day ahead and reheated in the microwave or on the stovetop just before serving).
