Ingredients
  

  • 2 tablespoons unsalted butter
  • 1 tablespoon olive oil
  • 3 medium leeks cleaned and sliced (white and light green parts only)
  • 2 garlic cloves minced
  • 4 medium potatoes peeled and diced
  • 4 cups vegetable or chicken stock 960 ml / 1 L
  • 1 cup whole milk or light cream 240 ml
  • Salt and freshly ground black pepper to taste
  • ¼ teaspoon nutmeg optional

For serving (optional):

  • Croutons or toasted bread cubes
  • Chopped chives or parsley
  • Crispy bacon bits
  • Drizzle of cream or olive oil

Instructions
 

Sauté the leeks

  • In a large pot, melt the butter with the olive oil over medium heat.
  • Add the sliced leeks and minced garlic and cook for 5–7 minutes until soft and fragrant, without browning.

Add the potatoes

  • Stir in the diced potatoes and cook for about 2 minutes, coating them well in the leek mixture.

Simmer

  • Pour in the stock, bring to a gentle boil, then reduce heat and simmer for 20–25 minutes until the potatoes are tender.

Blend

  • Remove from heat and blend the soup using an immersion blender or standard blender until smooth and creamy.

Finish the soup

  • Return the soup to the pot. Stir in the milk or cream, season generously with salt, pepper, and nutmeg if using.
  • Warm gently over low heat.

Serve

  • Ladle into bowls and top with croutons, herbs, bacon bits, and a drizzle of cream or olive oil. Serve with warm bread if desired.

Notes

Tips and Variations:
You can leave the soup slightly chunky by blending only part of it if you prefer more texture. For a dairy-free version, use olive oil instead of butter and substitute the milk with unsweetened oat milk or extra stock.
This soup also reheats beautifully, making it a great make-ahead option for busy days.
