Ingredients Needed to Make Delia Smith Leek and Potato Soup

  • 4 large leeks
  • 1 medium onion, chopped small
  • 2 medium potatoes, peeled and diced
  • 50g butter
  • 850ml vegetable stock
  • 275 ml milk
  • salt and freshly milled black pepper
  • 2 tablespoons cream or crème fraiche
  • 11/2 tablespoons snipped fresh chives or chopped fresh parsley

Equipment

You will also need the following equipment:

  • A large, thick-based saucepan
  • A wooden spoon
  • A sharp knife
  • A blender or a hand blender
  • A measuring jug
  • A chopping board
  • A ladle
  • A soup bowl

Instructions to Make Delia Smith Leek and Potato Soup

Now that you have all the ingredients and equipment ready, let’s get started with the method.

Step 1: Prepare the leeks

The first step is to prepare the leeks. You need to trim them, discarding the tough outer layer. Then, split them in half lengthways and slice them quite finely. Wash them thoroughly in two or three changes of water, and drain well. Leeks can be quite sandy, so make sure you rinse them well to avoid any grit in your soup.

Step 2: Cook the vegetables

The next step is to cook the vegetables. In a large, thick-based saucepan, gently melt the butter over low heat. Then, add the leeks, onion, and potatoes, stirring them all around with a wooden spoon so they get a nice coating of butter. Season with salt and pepper, then cover and let the vegetables sweat over very low heat for about 15 minutes. This will help them release their juices and soften without browning.

Step 3: Add the stock and milk

After 15 minutes, add the stock and milk to the saucepan, and bring to a simmering point. Cover and let the soup simmer very gently for another 20 minutes, or until the vegetables are soft. Be careful not to let the soup boil over, as the milk in it may cause it to do so. You can also stir the soup occasionally to prevent it from sticking to the bottom of the pan.

Step 4: Blend the soup

Once the vegetables are cooked, you can blend the soup to a smooth puree. You can use a blender or a hand blender for this. If you use a blender, you may need to do it in batches and make sure you have a bowl to hand to put the first batch into. Also, let the soup cool a little before blending, as hot liquids can splatter and cause burns. If you use a hand blender, you can do it directly in the saucepan, but be careful not to splash yourself or the surroundings.

Step 5: Reheat and serve

The final step is to reheat the soup gently, tasting it to check the seasoning. You can adjust the salt and pepper according to your preference. You can also add a swirl of cream or crème fraiche to each bowl before serving, and sprinkle with some freshly snipped chives or parsley. This will add some richness and freshness to the soup. Enjoy your leek and potato soup with some crusty bread or crackers, or on its own.

 FAQs

How do you make leek and potato soup without cream?

You can make leek and potato soup without cream by using dairy-free alternatives, such as almond, soy, or coconut milk and cream. You can also use nutritional yeast instead of cheese, for a cheesy flavor without dairy. Alternatively, you can skip the cream altogether and enjoy the soup as it is, or add some extra stock or water to thin it out if needed.

How do you thicken leek and potato soup?

Leek and potato soup usually thickens naturally as the potatoes break down and release their starch. However, if you want to make it even thicker, you can use one of these methods:

  • Blend some or all of the soup until smooth, using a blender or a hand blender. This will create a creamy and velvety texture.
  • Add some cornstarch or flour to the soup, whisking well to avoid lumps. This will create a thicker and denser texture. You can use about 1 tablespoon of cornstarch or flour for every 4 cups of soup.
  • Add some cheese to the soup, such as cheddar, gruyere, or parmesan, stirring until melted and smooth. This will create a richer and cheesier texture. You can use about 1/4 cup of grated cheese for every 4 cups of soup.
