What you will need

This recipe uses 6 simple ingredients that you can find at any grocery store:

  • 700 g floury potatoes peeled and diced
  • 2 large leeks trimmed washed and sliced
  • 1 medium onion finely chopped
  • 900 ml good quality vegetable or chicken stock
  • 100 ml double cream plus extra to serve
  • 30 g unsalted butter

Step by step instructions

Step 1: Soften the Aromatics

Melt the butter in a large heavy-bottomed pot over medium-low heat. Add the chopped onion and sliced leeks and cook gently, stirring occasionally, for about 10 minutes until completely softened and sweet but not browned. Season lightly with salt and pepper during this process.

Step 2: Add Potatoes and Stock

Add the diced potatoes to the pot and stir to coat them in the buttery leek mixture. Pour in the stock and bring to a boil over high heat. Reduce the heat to a steady simmer, partially cover the pot, and cook for 20 minutes until the potatoes are completely tender and beginning to break down.

Step 3: Blend Until Silky

Remove the pot from the heat. Use a stick blender to blend the soup directly in the pot until completely smooth and silky. Alternatively, transfer in batches to a countertop blender, always being careful with hot liquid. If the soup is too thick, add a little more warm stock to reach your preferred consistency.

Step 4: Finish with Cream and Serve

Return the pot to low heat if necessary and stir in the double cream. Taste and adjust seasoning generously. Ladle into warmed bowls and finish with a small swirl of extra cream and a grind of black pepper. Serve immediately with warm soda bread or crusty rolls.

Easy substitutions

Missing an ingredient? Here are some swaps that work perfectly:

  • double cream → full-fat coconut milk for a dairy-free version that adds a subtle sweetness
  • leeks → 3 extra onions if leeks are unavailable, though the soup will have a sharper rather than mellow onion flavor

Common mistakes to avoid

Watch out for these pitfalls that can affect your results:

  • Using waxy salad potatoes instead of floury varieties which do not break down properly and result in a grainy rather than silky smooth texture
  • Blending the soup while it is still at a rolling boil which can cause dangerous hot splatter especially when using a countertop blender
