Economical leek and potato soup
This leek and potato soup has always been my standby recipe back in the day when money was tight and I had three hungry mouths to feed.
It's made with a few potatoes, leeks and onions that always seem to end up at the bottom of the vegetable basket, and very little else to be honest. But in spite of the few ingredients, this leek and potato soup has the most amazing flavour which wouldn't be out of place in a restaurant!
In addition to the vegetables, all you will need is a stock cube and a cup of milk, a knob of butter along with some salt and pepper for seasoning, and you can have this hearty and tasty soup on the table in no time at all.
If you've got carrots or celery and a little leftover shredded ham, you can throw those in too, but you can get away with just using leeks, potatoes and onions.
And if you are feeling flush you can add a dollop of creme fraiche and a sprinkling of chopped chives or parsley for garnish. If you only have a piece of hard cheddar, grate that up and garnish the potato soup with that, or just serve it plain.
The beauty of potato and leek soup is that you can adjust the ingredients to use up whatever you have in your cupboard. Don't have butter? No problem, substitute it with margarine or even sunflower oil. Don't have milk? Well then, just add extra stock. If you have half a tub of cream cheese that needs to be used up, stir that in as well - it all adds to the flavour.
I like to serve leek and potato soup with a crusty baguette, but if you only have a few slices of stale bread, pop them in the toaster and serve those instead. They will taste just as good.
I'm giving you the basic recipe for the soup, but you can adjust it according to what you have on hand.
Let me show you how easy it is to make!
What you will need
Equipment
For making the soup you will need a large saucepan with a lid, and for blending the soup you will need a stick-blender.
Other than that, you will need a sharp knife and a chopping board for cutting up the vegetables.
Ingredients
This recipe will serve 4 people. You can adjust the quantities to suit your own family.
**You can get the complete list of ingredients and full instructions for making this potato and leek soup on the printable recipe card at the end of this post**
Potatoes - the potatoes should be peeled and cut into quarters.
Leeks - wash the leeks to remove any grit that may be in between the leaves, then cut them in half lengthwise and slice them into half-inch wide semicircles.
Onions - the onions should be peeled and cut into quarters.
Shredded ham - I like to use leftover gammon (see this post for how to roast gammon) but you could use chopped sandwich ham instead.
Stock pots - I used 1 chicken and 2 vegetable stock pots. If you don't have stock pots you can use stock cubes instead. And of course, if you have fresh stock (either chicken or vegetable) available you can use that.
Milk - I used 1 cup of milk. You can substitute with fresh single cream for a richer taste.
Butter - this is used for softening the vegetables - substitute with margarine or sunflower oil.
Salt and black pepper - for seasoning
For garnishing the soup you can use chopped parsley or chives, and a spoonful of creme fraiche. These are optional.
What to do
Melt the butter in a large saucepan, then add the chopped vegetables.
Saute them over low heat for about 5 minutes until the leeks and onions start to soften.
I forgot to take photos of the next steps I'm afraid - you'll have to use your imagination.
- Dissolve the stock pots or stock cubes in 4 cups (2 pints) of boiling water and pour it into the pan with the milk. Season the soup with salt and pepper.
- Cover the pan with a lid and bring the heat to a strong simmer (just below boiling). Cook for 30 to 40 minutes until the vegetables are completely soft.
Use a stick blender to blend the soup until it is thick and smooth. Taste for seasoning and adjust if necessary. I find this soup benefits from lots of ground black pepper - but that's to my taste!
If you are adding shredded ham, stir it in now and leave the soup on the heat until the ham has warmed through.
Ladle the soup into bowls, garnish with a spoonful of creme fraiche and chopped chives or parsley and serve hot with crusty bread.

Potato and leek soup is said to have originated in France in the late 18th century, having been developed by a French pharmacist Antoine-Augustin Parmentier. Up until then, potatoes had been regarded as only being fit for pig food and were thought to cause leprosy in humans. Apart from promoting potatoes as a food source in France and Europe, Parmentier is also remembered for establishing the first smallpox vaccination campaign under Napoleon's rule. He also studied methods of conserving food, including refrigeration.
