Ingredients

Scale
  • 2 tablespoons unsalted butter
  • 4 large leeks, white and light green parts only, sliced and cleaned
  • 2 cloves garlic, minced
  • 1.5 pounds Yukon Gold potatoes, peeled and diced
  • 4 cups low-sodium chicken broth (or vegetable broth for vegetarian)
  • 1 cup water
  • 1 teaspoon salt, or to taste
  • 0.5 teaspoon black pepper, or to taste
  • 0.5 cup heavy cream (or full-fat coconut milk for dairy-free)
  • Fresh chives, chopped, for garnish

Instructions

  1. Melt the butter in a large pot or Dutch oven over medium heat.
  2. Add the cleaned, sliced leeks to the pot. Sauté gently for 8 to 10 minutes until the leeks are very soft and translucent. Do not let them brown.
  3. Add the minced garlic and cook for 1 minute until fragrant.
  4. Add the diced potatoes, chicken or vegetable broth, water, salt, and pepper to the pot.
  5. Bring the mixture to a boil, then reduce the heat to low, cover, and simmer for 15 to 20 minutes, or until the potatoes are completely tender when pierced with a fork.
  6. Remove the pot from the heat. Use an immersion blender to blend the soup until it is completely smooth and velvety. Alternatively, carefully transfer the soup in batches to a standard blender and blend until smooth, then return it to the pot.
  7. Stir in the heavy cream (or coconut milk). Heat the soup gently over low heat until warmed through. Do not boil after adding the cream.
  8. Taste the soup and adjust salt and pepper as needed.
  9. Serve your potato leek soup hot, garnished with fresh chopped chives or homemade croutons.

Notes

  • To ensure a truly velvety texture, make sure you blend the soup thoroughly. If you prefer a slightly rustic texture, blend only partially.
  • For a dairy-free potato leek soup, substitute full-fat coconut milk for the heavy cream. This keeps the soup rich without dairy.
  • If you want to make a vegetarian potato leek soup, use vegetable broth instead of chicken broth.
  • This soup pairs well with simple croutons or thick slices of crusty bread for dipping.
