Potato Leek Soup


– 4 large leeks, white and light green parts only, cleaned and sliced
– 4 cups vegetable or chicken broth
– 2 tablespoons unsalted butter
– 2 large russet potatoes, peeled and diced into 1/2-inch cubes
– 1 medium onion, diced
– 2 cloves garlic, minced
– 1 cup heavy cream or whole milk
– Salt and freshly ground black pepper, to taste
– Chives or green onion tops, chopped (for garnish)
– Optional: Crisp bacon bits or shredded cheese for garnish
– Optional: A pinch of ground nutmeg for added flavor


  1. In a large pot, melt the butter over medium heat. Add the sliced leeks and onion and sauté until the onions are translucent and the leeks have softened, about 6-8 minutes. Be careful not to brown them. Add minced garlic and cook for an additional minute.
  2. Add the diced potatoes to the pot and stir to combine with the leeks and onions.
  3. Pour in the broth and bring the mixture to a boil. Once boiling, reduce the heat to low and simmer uncovered for 15-20 minutes, or until the potatoes are tender and can be easily pierced with a fork.
  4. Using an immersion blender, puree the soup until smooth. Alternatively, you can carefully transfer the soup in batches to a blender to puree.
  5. Stir in the heavy cream or milk, and continue to heat the soup gently. Do not boil after adding dairy. If the soup is too thick, you can thin it out with a little more broth or water.
  6. Season the soup with salt, pepper, and the optional pinch of nutmeg to taste.
  7. Continue to cook the soup on low heat for an additional 5-10 minutes, allowing the flavors to meld.
  8. Taste and adjust seasoning if necessary.
  9. Serve the Potato Leek Soup hot, garnished with chopped chives, green onion tops, bacon bits, or shredded cheese, if desired.
