This traditional soup blends sautéed leeks and onions with potatoes and stock to form a rich, smooth base. It’s finished with cream or milk for a silky texture. The natural sweetness of leeks complements the earthy potatoes, creating a well-balanced soup that’s both hearty and light. It’s typically served with warm bread, making it ideal for chilly days.
2 large leeks (trimmed, cleaned, and sliced)
2 medium potatoes (peeled and diced)
1 onion (chopped)
40g (3 tbsp) butter
750ml vegetable or chicken stock
100ml whole milk or double cream
Salt and freshly ground black pepper (to taste)
Fresh parsley or chives (for garnish)
Trim, wash, and finely slice the leeks. Dice the potatoes and chop the onion to ensure even cooking and a smooth texture later.
Melt butter in a large saucepan over medium heat. Add the chopped onion and sliced leeks, then cook gently for about 8–10 minutes until soft but not browned. Stir occasionally to avoid sticking.
Add diced potatoes to the pot and pour in the stock. Season lightly with salt and pepper. Bring to a boil, then reduce the heat and simmer for about 20 minutes until the potatoes are tender.
Once everything is soft, remove from heat and blend using a hand blender until smooth. For a rustic texture, blend only half and leave some chunks.
Stir in the milk or cream and heat gently—do not boil after adding cream. Adjust seasoning with extra salt or pepper as needed.
Ladle into bowls, garnish with chopped parsley or chives, and serve warm with crusty bread or buttered rolls.
