Ingredients

Scale

Vegetables

  • 3 large leeks (white and light green parts only, sliced and cleaned)
  • 4 medium-sized Russet or Yukon Gold potatoes (peeled and cubed)

Dairy & Fats

  • 4 tablespoons unsalted butter
  • 1 cup heavy cream

Liquids & Broth

  • 4 cups chicken or vegetable broth

Herbs & Spices

  • 2 bay leaves
  • 2 sprigs fresh thyme
  • Salt and white pepper to taste

Optional Garnishes

  • Chives
  • Croutons
  • Drizzle of olive oil


Instructions

  1. Sauté Leeks: Melt the unsalted butter in a large pot over medium heat. Add the sliced and cleaned leeks, cooking them gently until they become soft and fragrant, about 5 to 7 minutes. This will enhance their natural sweetness and form the flavor base of the soup.
  2. Add Potatoes: Add the peeled and cubed potatoes to the pot with the leeks and stir well to coat all the pieces with melted butter. This helps in building layers of flavor within the soup.
  3. Add Broth and Herbs: Pour in the chicken or vegetable broth, then add the bay leaves and fresh thyme sprigs. Bring the mixture to a boil, then reduce the heat and let it simmer gently for 15 to 20 minutes, or until the potatoes are tender when pierced with a fork.
  4. Remove Herbs and Blend: Carefully remove and discard the bay leaves and thyme sprigs. Using an immersion blender, blend the soup directly in the pot until smooth. Alternatively, transfer the soup in batches to a stand blender and blend until creamy.
  5. Finish Soup: Stir in the heavy cream to enrich the soup’s texture and flavor. Season the soup with salt and white pepper to taste, adjusting seasoning according to your preference. Optionally, garnish with chopped chives, croutons, or a drizzle of olive oil before serving.

Notes

  • For a vegetarian version, use vegetable broth instead of chicken broth.
  • You can substitute heavy cream with half-and-half or coconut cream for a lighter or dairy-free option.
  • Be sure to clean the leeks thoroughly to remove any grit trapped between layers.
  • This soup freezes well; cool completely before freezing and reheat gently to preserve texture.
  • For extra richness, you can stir in a bit of grated cheese like Gruyère just before serving.
