Step-By-Step Mary Berry Leek And Potato Soup Recipe

This method follows Mary Berry’s classic approach—gentle cooking, careful seasoning, and a smooth finish.
Preparing The Vegetables
Start by trimming the leeks, removing the dark green tops and root ends. Slice them lengthwise and wash thoroughly to remove any grit. Leeks often hide dirt between layers, so take your time with this step.
Peel and dice the potatoes into small, even chunks. Finely chop the onion.
Cooking The Base
Melt butter gently in a large saucepan over low heat. Add the chopped onion and leeks. Cover with a lid and allow them to soften slowly. This step is important—do not let the vegetables brown. Slow cooking brings out the leeks’ natural sweetness.
Adding Potatoes And Stock
Once the leeks and onions are soft, add the diced potatoes. Pour in enough stock to just cover the vegetables. Season lightly with salt and pepper.
Bring the soup to a gentle simmer, then cover and cook until the potatoes are tender. This usually takes about 15–20 minutes.
Blending The Soup
Remove the soup from heat and allow it to cool slightly. Blend until smooth using a hand blender or countertop blender. The texture should be velvety and creamy.
Return the soup to the pan and stir in milk or cream, depending on how rich you want it. Gently reheat without boiling.
Final Seasoning
Taste the soup and adjust the seasoning if needed. A small amount of black pepper enhances the flavor without overpowering the delicate leeks.
Texture And Flavor Tips From Mary Berry’s Style

Mary Berry’s cooking is all about finesse. Here are a few tips inspired by her approach:
- Never rush the leeks – slow cooking makes them sweet and mild
- Avoid boiling after adding milk or cream – it keeps the soup smooth
- Use floury potatoes – they give a naturally creamy texture
- Season lightly at first – adjust at the end
These small details elevate the soup from ordinary to exceptional.
