Ingredients

  • 3 leeks (white and light green parts only), cleaned and sliced
  • 4 medium russet or Yukon Gold potatoes, peeled and diced
  • 2 tablespoons unsalted butter or olive oil
  • 2 cloves garlic, minced (optional)
  • 4 cups vegetable or chicken broth
  • 1 teaspoon salt, or to taste
  • 1/4 teaspoon black pepper, or to taste
  • 1 bay leaf (optional)
  • Fresh herbs like thyme or parsley (optional)

Instructions

  1. Trim and slice the leeks, rinsing thoroughly to remove any grit.
  2. Heat butter or olive oil in a large pot over medium heat. Add the leeks and sauté until softened, about 5–7 minutes.
  3. If using garlic, add it now and cook for 1 minute until fragrant.
  4. Add diced potatoes to the pot and stir to combine with the leeks.
  5. Pour in the broth until vegetables are just covered. Add bay leaf and herbs if using, then bring to a boil.
  6. Reduce heat and simmer until potatoes are tender, about 15–20 minutes.
  7. Remove the bay leaf and puree the soup using an immersion blender or in batches in a regular blender until smooth and creamy.
  8. Season with salt and black pepper to taste and warm through before serving.

Notes

  • Use russet or Yukon Gold potatoes for a naturally creamy texture.
  • For extra smoothness, peel the potatoes; leave skins on for added nutrients and texture.
  • For a dairy-free version, use olive oil instead of butter.
  • Store leftovers in an airtight container in the fridge for up to 4 days.
  • Reheat gently on the stove, adding broth or water if the soup has thickened.
  • Freeze cooled soup for up to 2–3 months in freezer-safe containers; thaw overnight in the fridge before reheating.
