Leek and Potato Soup is one of my favourite winter soups. It’s one of a triumvirate of Scottish staple soups alongside Lentil Soup and Scotch Broth that appeared on every table when I was a child.
I make a large pot of soup every weekend which also provides warming lunches for the following week. It’s a real winter warmer and it’s also really easy to make.
How to make Leek and Potato Soup
First, peel the potatoes and cut into roughly even-sized pieces of about 4cm (1 1/2 in), you don’t have to be accurate.
If you want the soup to cook more quickly then cut all the vegetables smaller.
To prepare the leeks, slice off the root end and the very top of the leek, then slice vertically and place upside down in a tall jug of water.
Leave for 10-15 minutes, then agitate the leeks up and down to get rid of most of the earth which may be stuck in the ‘leaves’.
Slice horizontally, then if the leeks still seem to have a bit of earth on them put the sliced leeks in a bowl of cold water and move them around until they are clean, then drain.
Place the butter and a little oil in the bottom of your soup pot and heat to a medium temperature.
Add the leeks and potatoes and stir around for about 5 minutes. Until that the vegetables are covered in the oil and butter and the leeks have started to soften.
Once the leeks are soft, add the stock, then cook.
Soup Pot, Pressure Cooker or Instant Pot
I use my pressure cooker, so once up to pressure it only takes 15-20 minutes for the soup to cook.
In the Instant Pot, the recipe takes 12 minutes at medium pressure.
If you don’t have a pressure cooker then simmer fhe vegetables for abut 30-40 minutes depending on how large you have cut your vegetables.
Once cooked the soup is cooked add milk and blend the soup until smooth reheat and serve hot. For special occasions garnish with crispy fried onion and a swirl of cream.
Blending the Soup
To get the best texture I use the Optimum Froothie G2.3 Blender. It makes short work of blending soups and smoothies and they come out silky smooth with no grainy texture that you can get from the starch in potatoes.

A luxury version of Leek and Potato Soup
If you are serving this soup for a special occasion and want to be really decadent replace the milk with single or double cream to give a rich silky texture.
If you are a fan of truffles, then a little bit of shaved truffle would be a tasty garnish although the fried onions. Or fry some finely shredded leeks with a few herbs to add a special something to the soup.
