Leek Soup

This leek and potato soup is the kind of bowl that feels like a warm hug—silky, savory, and built on the sweet, onion-like flavor of gently sautéed leeks. It’s simple enough for a busy weeknight but elegant enough to serve when friends drop by; a little chive cream swirled on top brightens the whole thing and makes it feel special.

I love how forgiving this recipe is: trim and rinse the leeks, simmer until the potatoes fall apart, and blitz until velvety. You can make it entirely vegetarian, swap in broth you love, or keep a bit of reserved cream for a glossy finish—either way, it’s cozy, comforting cooking that rewards minimal fuss.

Ingredients

  • 2 pieces Leeks, white and light green parts only, sliced and rinsed
  • 1.5 lb Russet potatoes, peeled and diced
  • 1 pieces Yellow onion, diced
  • 2 pieces Garlic, minced
  • 2 tbsp Unsalted butter
  • 1 tbsp Olive oil
  • 4 cups Vegetable or chicken stock
  • 1 tsp Fresh thyme or 1/2 tsp dried thyme
  • 1 pieces Bay leaf
  • 1.5 tsp Kosher salt (adjust to taste)
  • 0.5 tsp Black pepper, freshly ground
  • 1/2 cup Heavy cream (for soup)
  • 2 tbsp Extra heavy cream (for chive cream garnish)
  • 2 tbsp Fresh chives, finely chopped
  • 1 tbsp Fresh lemon juice
  • 1/4 cup Grated Parmesan (optional garnish)

Instructions

  1. Trim and halve the leeks lengthwise, then slice thinly and rinse to remove grit. Pat dry.

  2. Heat butter and olive oil in a large pot over medium heat. Add the diced onion and leeks and cook, stirring occasionally, until very soft and fragrant, about 8–10 minutes.

  3. Add the minced garlic and cook 30 seconds more, then add the diced potatoes, thyme, bay leaf, stock, salt, and pepper. Bring to a simmer.

  4. Reduce heat and simmer gently until the potatoes are very tender, about 20 minutes.

  5. Remove the bay leaf and use an immersion blender to puree the soup until smooth and velvety. Alternatively, work in batches in a blender and return to the pot.

  6. Stir in the 1/2 cup heavy cream and lemon juice. Warm through for a minute or two; taste and adjust seasoning.

  7. Make the chive cream garnish by whisking the extra 2 tbsp heavy cream with the chopped chives and a pinch of salt.

  8. Ladle soup into bowls, drizzle a spoonful of chive cream on each, and finish with a grind of black pepper and a sprinkle of Parmesan if using.

  9. Serve hot with crusty bread for dipping and enjoy the comforting flavors.

Tips & Notes

  • Trim leeks carefully—dirt hides between layers. Slice first, then rinse in a bowl of cold water and lift out the grit.
  • For a dairy-free version, substitute coconut cream or an extra splash of olive oil and omit the chive cream or use a cashew cream.
