Ingredients
  

  • 2 bunches leeks white and light green parts only, cleaned thoroughly
  • 3 medium russet potatoes peeled and cubed
  • 750 ml vegetable broth preferably homemade or low-sodium
  • 100 ml heavy cream or Greek yogurt for a lighter option
  • 2 tablespoons butter for sautéing
  • to taste salt adjust to preference
  • to taste white pepper or black pepper
  • 1 teaspoon fresh thyme optional, added during simmering

Equipment

  • Large heavy-bottomed pot
  • Sharp knife
  • Wooden spoon
  • Immersion blender or regular blender

Method
 

  1. Trim the dark green tops and root ends off the leeks. Slice them in half lengthwise, then chop into thin half-moons. Rinse thoroughly in cold water to remove any grit, then set aside.
  2. Peeled potatoes are cut into roughly 1.5 cm cubes to ensure even cooking. Keep the cubes ready nearby.
  3. Place a large heavy-bottomed pot over medium heat. Add butter and let it melt with a gentle sizzle.
  4. Add the sliced leeks to the pot. Sauté slowly for about 7 minutes, stirring occasionally, until they soften, turn translucent, and emit a sweet aroma. Adjust the heat if they start to brown.
  5. Stir in the cubed potatoes, coating them gently with the butter and leeks. Cook for another 3 minutes, allowing the potatoes to start softening.
  6. Pour in the vegetable broth, then add the thyme if using. Bring the mixture to a gentle simmer, just below boiling point, and partially cover with a lid.
  7. Cook for 20-25 minutes, stirring occasionally, until the potatoes are fork-tender and the aroma is fragrant. The leeks should be melting into the broth.
  8. Remove the pot from heat. Use an immersion blender directly in the pot, or carefully transfer the soup in batches to a blender. Puree until silky and smooth, with a velvety texture.
  9. Return the blended soup to low heat. Stir in the heavy cream, warming gently for about 2 minutes without boiling. Taste and adjust salt and white pepper as needed.
  10. Let the soup rest off heat for 5 minutes to allow flavors to meld. The silky, fragrant soup is now ready to serve, garnished with a swirl of cream or a sprinkle of fresh herbs if desired.

Notes

For a lighter version, substitute heavy cream with Greek yogurt or coconut milk. Use an immersion blender for easiest pureeing and minimal splashes. Adjust seasoning at the end for perfect flavor balance.
