Watercress Soup

This recipe is actually taken from a project that I did while attending the French Culinary Institute. It isn’t fancy, and comes together very quickly—perfect for a lazy weekend or a weeknight meal. My inspiration came from the many watercress and egg salads that I eat when I visit my grandmother in England every summer. Watercress is not very popular in this country, but it is used very frequently by the British in sandwiches, soups, and salads. If you have the ingredients on hand, I urge you to make the lemon crème fraiche that accompanies this soup. It adds a touch of creaminess and a refreshing burst of citrus to the soup. However, if you don’t have the time or ingredients, feel free to do without or to substitute a dollop of yogurt or sour cream instead. This soup would make a great appetizer (which was its original intention), or a light meal served with some crusty, buttered bread. It can also be served either hot or chilled, which makes it perfect for both the summer and the winter!

Happy Cooking, Pippa

Watercress Soup with Lemon Crème Fraiche Serves 8, 150mL portions (or 4 entree portions)

I chose to pair this soup with the 2009 Ata Rangi Sauvignon Blanc from Martinborough, New Zealand because this wine is bright and citrusy and has some peppery notes, which is a perfect compliment for the pepperiness of the watercress and the lemon crème fraiche that garnishes the soup.

For the Watercress Soup:

  • 1 leek (95g), white parts only, chopped finely
  • 2-3 T unsalted butter
  • 3 bunches (477g) of watercress (thick stalks removed)
  • 1 medium yukon gold potato (medium sized, peeled and cut in ½ inch cubes)
  • 1,185mL (5 cups) Vegetable Stock
  • ½ t Lemon Juice
  • 1 T Heavy Cream
  • Salt and Black Pepper (as needed)
  • Extra Virgin Olive Oil (as needed)

Instructions for the Watercress Soup:

  1. Place a marmite over low heat. Sweat the leeks in the butter until translucent.
  2. Add the potato and cook for an additional 1-2 minutes over low to medium heat.
  3. Add the vegetable stock and bring to a boil.  Reduce the heat and simmer for approximately 10 minutes, or until the potatoes are completely cooked through.
  4. Add the watercress to the pot and continue to simmer for an additional 2 minutes, or until the watercress has wilted.
  5. Remove the soup from the heat and puree the soup in batches in a blender.
  6. Return the pureed soup to the low heat and stir in the lemon juice and cream.
  7. Serve hot with a dollop of lemon crème fraiche and a few drops of Extra Virgin Olive Oil.
