Step-by-Step Instructions of Potato Leek Soup

  1. Melt butter in a large heavy-bottomed pot over medium heat.
  2. Add chopped leeks. Stir to coat, then cover and cook on low heat for about 10 minutes until very soft (do not brown).
  3. Increase heat to medium-high. Add garlic, cubed potatoes, salt, and pepper. Cook for 1 minute, stirring.
  4. Pour in vegetable broth, water, thyme sprigs, and bay leaf. Bring to a boil.
  5. Reduce heat to low, cover, and simmer for 15–20 minutes until potatoes are very tender.
  6. Remove thyme sprigs and bay leaf (discard).
  7. Using an immersion blender (or working in batches with a regular blender), purée until completely smooth and creamy.
    Tip: Pulse rather than over-blend to prevent gummy texture from potato starch.
  8. Stir in fresh chives and a few dashes of hot sauce if desired. Taste and adjust seasoning.
  9. Serve hot with your favorite toppings: croutons, extra chives, a swirl of cream, crispy bacon, or fried leek rings.
