Ingredients

Scale
  • 2 tablespoons unsalted butter
  • 4 large leeks, white and light green parts only, thoroughly cleaned and sliced
  • 2 pounds Yukon Gold potatoes, peeled and roughly chopped
  • 6 cups vegetable or chicken broth
  • 1 cup heavy cream (or full-fat coconut milk for dairy-free)
  • 1 teaspoon salt, or to taste
  • 1/2 teaspoon black pepper, or to taste
  • Optional garnish: fresh chives or crumbled bacon

Instructions

  1. Melt the butter in a large pot or Dutch oven over medium heat.
  2. Add the sliced leeks to the pot. Sauté for 8 to 10 minutes, stirring occasionally, until the leeks are very soft and sweet. Do not let them brown.
  3. Add the chopped potatoes and broth to the pot. Bring the mixture to a boil, then reduce the heat, cover, and simmer for 15 to 20 minutes, or until the potatoes are completely tender when pierced with a fork.
  4. Remove the pot from the heat. Use an immersion blender to blend the soup directly in the pot 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.
  5. Stir in the heavy cream, salt, and pepper. Heat the soup gently over low heat until warmed through; do not boil after adding the cream.
  6. Taste and adjust seasoning as needed. Serve your best potato leek soup hot, garnished with fresh chives or crispy bacon if desired.

Notes

  • For the creamiest texture, use starchy potatoes like Russets or Yukon Golds.
  • If you prefer a rustic soup, skip the blending step and simply mash some of the potatoes against the side of the pot.
  • This soup is great for meal prep; it freezes well for up to three months.
  • If you are looking for a dairy-free potato soup, substitute the heavy cream with full-fat coconut milk or cashew cream.
