Vichyssoise

Print

Summer has officially arrived, and with it, the dry summer heat for which Sacramento is so well known. Chilled soups were invented for hot days like these. Vichyssoise, a chilled creamy potato and leek soup, was created by a chef at the Ritz-Carlton in New York in the summer of 1917, to help keep patrons cool.

Chef Louis Diat was French, hence the French name of the soup. (Don’t try asking for a Vichyssoise in France, you’ll get puzzled looks; it’s an American soup).

Chilled soups used to be a lot more popular than they are these days, especially before WWII and modern air conditioning.

Vichyssoise

The original Vichyssoise is a cream bomb, calling for a quart of broth, 2 cups of milk, and 3 cups of cream, for eight servings. Yikes. That’s almost a half cup of cream per serving!

Our version is decidedly lighter, though still quite creamy because we use Yukon gold potatoes, which are naturally creamy potatoes (they make great mashed potatoes too).

The soup is really easy to make, doesn’t use a lot of ingredients, and lasts for days.

The trick is serving temperature. It’s great hot, though it is designed to be a chilled soup. I found the best serving temperature is just below room temp. Too cold and and the flavor from the butter, potatoes, and salt just disappears.

Vichyssoise Recipe

Print
  • Prep time: 15 minutes
  • Cook time: 1 hour
  • Yield: Makes about 10 cups, serves 6 to 8

Ingredients

  • 4 Tbsp butter
  • 4-5 cups sliced leeks, cleaned (see How to Clean Leeks), white and pale green parts only (from about 4 large leeks)
  • 1 medium onion, chopped or sliced
  • 2 lbs Yukon gold potatoes, peeled and chopped
  • 6 cups water (vegetarian option), or chicken stock
  • 2 teaspoons Kosher salt (more to taste)
  • 1/2 cup sour cream
  • 1/2 cup heavy whipping cream
  • Chopped fresh chives for garnish

Method

1 Heat butter until it begins to brown: In a large (6-quart) pot, heat the butter on medium high heat until it melts and foams up. Continue to heat until the foam subsides a little and the butter just begins to brown.

2 Sauté leeks and onions: Immediately toss in the sliced leeks and onions. Stir to coat with the butter. Cook for several minutes, reducing the heat to medium if necessary, until the leeks and onions are translucent and wilted.

3 Add potatoes, water or stock, salt, bring to simmer: Add the chopped potatoes, salt, and water or stock. Bring to a boil, reduce to a simmer. Cook, partially covered for 30-40 minutes, until the potatoes are completely cooked through. Remove from heat.

4 Purée until smooth: Purée using an immersion blender or working in batches, blend in a blender. (Careful! With hot liquids only fill the blender 1/3 of the way full, and hold the blender top on with your hand while blending.) Purée until completely smooth.

If you want an even smoother soup, you can take the extra step of pressing the purée through a sieve with a rubber spatula.

5 Cool and stir in sour cream and whipped cream: Allow to cool a bit before stirring in the sour cream and whipped cream. Allow to cool completely and chill in the refrigerator. The soup should be served just below room temperature (maybe 65°F or 18°C). If it is too cold, it won't taste as good.

Add more salt to taste. Serve garnished with chopped fresh chives.

    One thing to add that gives it an extra kick is Gold caviar!

    I really love vichyssoise and it’s something you cannot find — you have to make it yourself. This recipe is fantastic. I have made it multiple times and it has turned out great every time. It keeps for days, and is still flavorful on the third day as the first. One of the things I really love is how simple it is to remember the ingredients. I’ll be in the supermarket and see fresh leeks, which reminds me of this soup, and I remember the rest of the ingredients easily — golden potatoes, chicken broth, sour cream and heavy cream. Simple! Yes, I forget the onion, but who doesn’t have a bag of onions around?! Using golden potatoes does make a difference. I’ve tried this recipe with other types, and it’s just not the same. Try this recipe. You’ll like it!

    I am generally not a soup person, but I’ve been bookmarking possibilities that might convert me. I think this definitely makes the list!

    Thank you for this recipe! I made it on Saturday and have been enjoying it since. I was with a friend and we made 3 of your recipes- Vichyssoise, Gazpacho and Zucchini Cake! All three recipes were incredible (as I knew they would be).

    I’m so glad you liked the recipes! ~Elise
