Ingredients

Units Scale
  • 3 tablespoons salted butter (or olive oil)
  • 2 large or 4 small leeks (4 cups thinly sliced), white and light green parts
  • 3 celery ribs
  • 3 garlic cloves, minced
  • 2 pounds russet potatoes, peeled and small diced (5 cups diced)
  • 4 cups vegetable broth or chicken broth
  • 1 cup water
  • 3 sprigs fresh thyme (or a bouquet garni)
  • 1 bay leaf
  • 1 1/4 teaspoons kosher salt
  • 1/2 cup heavy cream
  • Chives, for garnish

Instructions

  1. Sauté Leeks and Vegetables:
    1. In a large pot or Dutch oven, melt the butter (or olive oil) over medium heat.
    2. Add the leeks, celery, and garlic.
    3. Cook, stirring occasionally, for 7 to 8 minutes, until the leeks are very tender but not browned.
  2. Simmer Soup:
    1. Add the chopped potato, vegetable broth (or chicken broth), water, fresh thyme (or bouquet garni), bay leaf, and salt.
    2. Bring to a simmer.
    3. Simmer for 20 minutes, or until the potatoes are tender.
    4. Remove the thyme and bay leaf.
  3. Blend Soup:
    1. Transfer the soup to a blender and blend until smooth.
    2. Return to the pot.
  4. Add Cream and Season:
    1. Add the heavy cream and blend again to combine.
    2. Taste and adjust seasonings as desired.
  5. Serve:
    1. Serve hot, garnished with fresh chives.

Notes

  • Ensure you use only the white and light green parts of the leeks.
  • For a vegan version, use vegetable broth and omit the heavy cream.
  • You can use an immersion blender to blend the soup directly in the pot.
  • Adjust the consistency by adding more broth or water if needed.
  • For a richer flavor, you can sauté the leeks for a longer time, allowing them to caramelize slightly.
  • You can add other vegetables, such as carrots, for additional flavor and texture.
  • Serve with crusty bread or croutons for dipping.
