Asparagus and leeks are both available in April and May when there is little else ready for eating. See our guide on how to grow leeks.
Combined together they make a healthy, light, creamy tasting soup good for adults and children.
Ingredients – Asparagus & Leak Soup
How To Make The Soup
Asparagus spears are best picked when young. If you want to use up taller, thicker spears in a soup, it may be worth peeling or shaving them before cooking. The asparagus is prepared by thoroughly cleaning and chopping into 5cm or 2 inch lengths.
Leeks are a very hardy vegetable that mature and swell with the spring rain. Leeks should be dug up and thoroughly cleaned – it is common for soil to be trapped within the layers of skin.
Once the leeks are washed and the upper leaves cut away, they can be roughly chopped. A final wash and rinse should remove any remaining dirt.
The soup also uses a small potato, chopped into small pieces, for flavour and to help thicken the soup, and about 750g of vegetable stock (or a little more if you like a thinner soup).
The first step is to sweat the leaks to sweeten them. Pour some olive oil in a pan, add the leaks, cover with a lid, and cook over a medium heat. Regularly stir the leaks to prevent them sticking. After five to ten minutes the leaks will be ready – taste for sweetness. If the leeks are crunchy they need a little more cooking.
Next, all the remaining ingredients are added to the pan – the vegetable stock, asparagus, and potatoes.
The mixture should be returned to the boil, and then left to gently simmer over a low heat for a further 15 minutes. Cooking is complete when all the vegetables are soft – almost crumbly – when touched with a fork.
The next stage is to liquidise the soup with a blender. For a more liquid soup without bits, the mixture can be strained through a sieve. This gives a fine soup with a delicate flavour.
The ingredients provide soup for four hungry people, recommended to serve with fresh bread.
