Cream of leek soup is a comforting classic that showcases the subtle, sweet flavour of leeks paired with the creamy texture of potatoes. This velvety soup is both simple and elegant, making it a perfect starter for a dinner party or a cosy night in. Leeks, with their mild onion-like taste, are the star of this dish. However, they can often be gritty due to the way they grow in sandy soil. Properly cleaning them is essential to achieving a smooth, grit-free soup. Paired with potatoes, this soup becomes a luscious blend that's delicious whether served hot or chilled as a traditional vichyssoise.

Soup Base

Instructions

Prepare the leeks

Thoroughly wash the leeks by slicing them lengthwise and rinsing under running water to remove all grit. Pat dry and slice thinly.

Pro tip: Leeks often have dirt trapped between their layers; ensure they are clean to avoid a gritty soup.

Sweat the leeks

In a large pot, melt the butter over medium-low heat. Add leeks and cook, stirring occasionally, for about 10 minutes or until soft but not browned.

Pro tip: Sweating the leeks without colour helps maintain the pale colour of the soup.

Cook the potatoes

Add the diced potatoes and vegetable broth to the pot. Bring to a boil, then reduce heat to low and simmer for 20 minutes, or until potatoes are tender.

Blend the soup

Using an immersion blender, blend the soup until completely smooth. Alternatively, transfer to a blender in batches.

Pro tip: Ensure the soup is fully blended for a velvety texture.

Add the cream

Stir in the heavy cream and season with salt and white pepper to taste. Heat gently until warmed through.

Pro tip: Do not bring the soup to a boil after adding the cream to prevent curdling.

Serve the soup

Ladle into bowls and serve hot, or allow to cool and refrigerate for at least 2 hours to serve as a chilled vichyssoise.

Pro tip: Garnish with a drizzle of cream or a sprinkle of fresh herbs for added flavour.
