Substitutions and Variations
Mary Berry Leek and Potato Soup is beautifully simple, but it also welcomes small adjustments. If you want a lighter version, you can reduce the cream or replace it entirely with extra stock. The soup will still be smooth and comforting, just a little less rich.
For a slightly different flavor profile, you can add a small clove of garlic when cooking the leeks and onion, or include a sprig of thyme while the soup simmers. Remove the thyme before blending.
A pinch of nutmeg also pairs nicely with leeks and potatoes, adding warmth without dominating the flavor.
If you prefer texture, you can blend only part of the soup and leave some potato pieces whole. This creates a rustic version that still feels comforting.
While Mary Berry’s version leans toward smooth and elegant, these variations allow you to adapt the soup to your taste while keeping its gentle character intact.
Make Ahead Tips
This soup is an excellent make-ahead option, which makes it ideal for busy weeks or relaxed entertaining. You can prepare it fully, allow it to cool, and store it in the refrigerator for up to 3 days. In fact, the flavor often improves slightly after a day as everything settles.
When reheating, warm the soup gently over low to medium heat, stirring occasionally. Avoid boiling, especially if cream has been added, as this can affect the texture. If the soup thickens too much during storage, simply add a splash of stock or water to loosen it.
You can also freeze this soup successfully. For best results, freeze it before adding the cream. Thaw overnight in the refrigerator, reheat gently, and stir in the cream just before serving. Make-ahead flexibility is one of the reasons Mary Berry Leek and Potato Soup remains such a practical, everyday favorite.
Instructions
Step 1: Prepare the vegetables
Trim the leeks, removing the tough green tops. Slice them lengthwise and wash thoroughly to remove any grit, then slice into thin rounds. Finely chop the onion and dice the potatoes into even pieces.
Step 2: Sweat the leeks and onion
In a large saucepan, heat the butter and olive oil over low heat. Add the sliced leeks and chopped onion. Cover and cook gently for 8 to 10 minutes, stirring occasionally, until soft but not browned.
Step 3: Add the potatoes
Add the diced potatoes to the pan and stir to combine with the leeks and onion.
Step 4: Add the stock
Pour in the stock, making sure the vegetables are fully covered. Bring the mixture to a gentle boil.
Step 5: Simmer the soup
Reduce the heat and simmer for 15 to 20 minutes, or until the potatoes are completely tender.
Step 6: Blend the soup
Remove the pan from the heat. Blend the soup until smooth using an immersion blender, or transfer it in batches to a blender.
Step 7: Add the cream
Return the blended soup to the pan if needed and stir in the double cream. Heat gently without boiling.
Step 8: Season to taste
Season with salt and freshly ground black pepper, adjusting to taste.
Step 9: Check consistency
If the soup is too thick, add a little extra stock or water until it reaches your desired consistency.
Step 10: Serve
Ladle the soup into bowls, garnish with a swirl of cream and chopped herbs if desired, and serve warm.
