Welcome to my kitchen! This classic potato leek soup recipe delivers that silky, comforting texture you crave, inspired by French techniques but simplified for your busy weeknight table. It uses simple ingredients to create a rich, velvety soup perfect for any cozy dinner.

Ingredients

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

Instructions

  1. Clean the leeks well to remove any grit. Slice the white and light green parts thinly.
  2. In a large pot or Dutch oven, melt the butter over medium heat. Add the sliced leeks and cook slowly, stirring occasionally, for 8 to 10 minutes until they are very soft and sweet. Do not let them brown.
  3. Add the minced garlic to the pot and cook for 1 minute until fragrant.
  4. Add the diced potatoes, broth, salt, and pepper to the pot. Increase the heat to 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.
  5. Remove the pot from the heat. Use an immersion blender to carefully blend the soup directly in the pot until it is completely smooth and velvety. Alternatively, transfer the soup in batches to a standard blender (vent the lid and cover with a towel to prevent steam buildup) and blend until smooth before returning it to the pot.
  6. Stir in the heavy cream (or coconut milk). Heat gently over low heat until warmed through; do not boil after adding the cream.
  7. Taste the soup and adjust salt and pepper as needed.
  8. Serve hot, garnished with fresh chives if desired. This soup pairs wonderfully with crusty bread for dipping.

Notes

  • For the best flavor, always sauté the leeks slowly before adding the liquid; this sweetens them significantly.
  • If the soup seems too thick after blending, add a splash more broth or water until you reach your preferred consistency.
  • To make this a vegan creamy soup, substitute the heavy cream with full-fat canned coconut milk or cashew cream.
  • If you want a richer flavor, sauté 2 slices of chopped bacon until crisp before starting; remove the bacon bits to use as a garnish later, and use 1 tablespoon of the rendered bacon fat instead of butter for sautéing the leeks.
