Vichyssoise recipe in a white bowl

One thing to keep in mind when preparing cold soup is that it will need seasoning to be increased just a bit as cold food doesn't hit the tastebuds like warm food does.

This soup gets its flavor from a delicate balance of potatoes and leeks. Cream or half and half is added for a velvety mouthfeel (this is not the time to go lowfat!). Plan enough time ahead when making this so it can thoroughly chill overnight.

Getting all the dirt, grit, and sand out of leeks is imperative when making this soup. Leeks grow up through the soil and embed themselves into the leaves and stay there until you release the dirt with this method. To clean leeks, slice the leeks into 1/2" rounds and put them in a big bowl of cool water, Work the inner layers apart so the rings separate and the earth will release.

  • 1 pound leeks
  • 1/2 cup yellow onion chopped
  • 1/4 c. unsalted butter
  • 1 pound potatoes peeled and cut into 1/2" cubes
  • 1/2 tsp salt
  • dash white pepper

  • chives for garnish

Remove the roots of the leeks and trim into half inch slices going up to the medium light green point (reserve the tops for stock). Place in medium bowl of cool water and work rings apart so any sediment releases to the bottom of the water. Let the rings float to the top while the dirt settles to bottom of bowl. You should have approximately 2 c of trimmed leeks. carefully remove rings so the bottom sediment is not disturbed.

Meanwhile, melt butter in a soup pot or dutch oven. Over medium heat, sautee cleaned leeks and onion until soft and golden. This will take approximately 5 minutes. Do not let the vegetables brown or it will discolor the soup which should be almost white when done.

Add potato, salt, pepper and broth to vegetables. Bring to a boil and simmer covered for about 40 minutes or until potatoes are soft almost falling apart. Remove pot from heat.
