Sunchoke Soup - Recipe

Recipe Category: Soups, Stews, Chili

Yield: 4 Servings


  • 1 tablespoon (15 g) unsalted butter
  • 2 yellow onions, diced
  • 3 stalks celery, diced
  • 1 pound (450 g) sunchokes (Jerusalem artichokes), peeled and sliced
  • 1 clove garlic, minced
  • 1 shallot, minced
  • 1/4 cup (60 ml) dry white wine
  • 2 cups (475 ml) chicken stock
  • 1 cup (240 ml) heavy cream
  • Salt and freshly ground pepper

  • Froth:
  • 1 cup (240 ml) 2% milk
  • 5 peppercorns, cracked
  • 3 thyme sprigs
  • 1 cup (235 g) grated Parmigiano reggiano
  • 2 teaspoons (10 g) salt

  • Garnish:
  • Tarragon leaves and flowers


  • In a heavy bottom stockpot over medium heat, melt butter and saute onions and celery for 3 minutes or until onion is translucent. Add sunchokes, garlic and shallots and cook for 2 minutes. Deglaze with white wine and add chicken stock. Bring to a boil and simmer for 25 to 30 minutes or until sunchokes are tender to the touch. Transfer into a food processor and blend until smooth.
  • Pour mixture into a clean pot, whisk in heavy cream and bring to a simmer. Adjust seasoning with salt and pepper. Remove from heat and keep warm.
  • For froth, in a small saucepan over medium heat, combine 1/4 cup (60 ml) milk, peppercorns and thyme and warm until milk bubbles around the edges. Whisk in cheese and season with salt. Transfer into a glass bowl and let cool.
  • Just before serving, in a small saute pan over high heat, mix a small amount of cheese mixture and milk and whisk briskly until warm and frothy. Repeat as many times as necessary.
  • To serve, pour soup into warmed soup bowls and garnish with a spoonful of froth and tarragon leaves.
