Ingredients

Scale
  • 3 tablespoons unsalted butter
  • 3 large leeks, white and light green parts only, thoroughly washed and sliced
  • 3 cloves garlic, minced
  • 2 pounds Yukon Gold potatoes, peeled and diced into 1-inch chunks
  • 6 cups low-sodium vegetable broth
  • 2 bay leaves
  • 1 teaspoon dried thyme
  • 1 cup whole milk
  • Salt and freshly ground black pepper, to taste
  • Fresh chives, for garnish

Instructions

  1. Melt butter in a large Dutch oven or heavy-bottomed pot over medium heat. Add sliced leeks and a pinch of salt. Cook, stirring occasionally, for 8-10 minutes until soft and sweet, but not browned.
  2. Add minced garlic and cook for 1 minute until fragrant.
  3. Add diced potatoes, vegetable broth, bay leaves, and thyme to the pot. Increase heat to high and bring to a boil.
  4. Once boiling, reduce heat to a gentle simmer. Partially cover the pot and cook for 20-25 minutes, until potatoes are completely fork-tender.
  5. Remove bay leaves. Using an immersion blender, carefully blend the soup directly in the pot until completely smooth.
  6. Return the pot to low heat. Stir in the whole milk and warm through gently; do not let it boil.
  7. Season generously with salt and pepper to taste.
  8. Ladle soup into bowls. Garnish with fresh chives and a crack of black pepper before serving.

Notes

For a dairy-free version, use olive oil instead of butter and full-fat coconut milk instead of whole milk. Ensure leeks are washed thoroughly to remove grit. Soup thickens upon standing; thin with a splash of broth or milk when reheating.
