Description

Julia Child’s Creamy Potato Leek Soup is a classic, comforting dish featuring tender Yukon gold potatoes and sautéed leeks blended into a smooth, velvety soup enriched with heavy cream and garnished with fresh thyme and a drizzle of olive oil.


Ingredients

Scale

Main Ingredients

  • 2 tablespoons olive oil, plus more for garnish
  • 2 tablespoons unsalted butter
  • 1 pound Yukon gold potatoes, peeled and chopped into ½ inch cubes
  • 2-3 medium leeks, cut in half, sliced, and cleaned well
  • 1 teaspoon Kosher salt, to taste
  • ½ teaspoon ground black pepper, plus more for garnish
  • 5 cups vegetable stock
  • ½ cup heavy cream
  • Fresh thyme leaves, removed from stem, for garnish


Instructions

  1. Sauté the leeks: Bring a medium pot to medium heat and add the butter and olive oil. Once melted, add the leeks and sauté for 5-7 minutes until softened but not caramelized.
  2. Add potatoes and season: Add the cubed Yukon gold potatoes to the pot and season with Kosher salt and ground black pepper.
  3. Add stock and simmer: Pour in enough vegetable stock to completely cover the vegetables. Cover the pot with the lid, leaving a small opening, and bring to a strong simmer.
  4. Cook until tender: Let the soup simmer until the potatoes are incredibly tender, about 35 minutes.
  5. Blend the soup: Turn off the heat and use an immersion blender or high-powered blender to blend the soup until incredibly smooth and creamy.
  6. Mix in cream: Stir in the heavy cream until fully incorporated.
  7. Serve and garnish: Ladle the soup into bowls and garnish with fresh thyme leaves, a drizzle of olive oil, and additional black pepper and salt to taste.

Notes

  • Use only the light green and white parts of the leek; the dark green parts are too fibrous but can be saved to make homemade stock.
  • Ensure there is enough stock to completely cover the vegetables to avoid the soup becoming gummy.
  • Sautéing the leeks before adding other ingredients sweetens their flavor.
  • Blend the soup while it is still warm to achieve a smooth, creamy texture easily.
  • Leeks freeze very well; slice thin, wash and dry thoroughly, then store in a resealable plastic bag for future use.
