Serves 24


  • 7 1/2 lbs purple potatoes, peeled, quartered

  • 3 1/2 lbs yellow onion, peeled, chopped
  • 10 quarts chicken stock
  • 10 cups half and half

  • 1/2 cup vegetable oil
  • 1/2 cup pomegrante seeds (for garnish)
  • 8 Tablespoons toasted fennel seeds
  • 4 Tablespoons salt

1. Heat vegetable oil in a 24 quart stock pot; add the onions and leeks and sweat until translucent. Add the potatoes then the stock, and bring to a boil. Once boiling, turn down to a simmer. Simmer 1 hour.

2. While simmering, warm the half and half in a sauce pot and add the toasted fennel seeds. Bring to a simmer and steep until the half and half bubbles.

3. Strain the half and half; discard fennel seeds.

4. Puree the potato soup with an immersion blender until smooth. Add the half and half, puree again. Add the yogurt, puree again. Chill if serving cold.

5. Bring back to simmer if serving hot. Top with pomegranate seeds.

Chef’s notes: Soup can be served hot or cold. Soup can be garnished with roasted/sliced purple potato croutons, pomegranate seeds, and/or crispy leeks and dollop of Greek yogurt.
