Scottish Chicken and Leek Soup is a traditional soup that is also known as Cock-a-Leekie. Made with leeks and chicken stock with a little rice, this is a simple and very delicious recipe that you can make on the stove, in your Slow Cooker or pressure cooker.
Why make Scottish Chicken & Leek Soup (Cock-a-Leekie)?
If you look at the ingredients for Cock-a-Leekie Soup and it’s easy to think that this soup is rather plain. But you would be so very wrong! Whatever you do you must sautee the leeks in butter. This process mellows the leeks so that when they meet the chicken stock they simply melt into the stock and produce a slight sweetness that you just don’t expect.
What is Cock-a-Leekie Soup?
Cock-a-Leekie Soup is very simply Chicken (Cock) and Leek (Leekie) Soup. It’s a very old and traditional Scottish Soup and there are many references to Cock-a-Leekie or Cocky Leekie in Scottish literature.
Sir Walter Scott writes in his novel The Fortunes of Nigel (1822) “The King: Come my Lords and Lieges, let us all go to dinner for the cocky leeky is a cooling.” The novel is one of the Waverley novels and is set in London in either 1623 or 1624.
What ingredients will I need?
According to F. Marian McNeill in The Scots Kitchen, the ingredients for a traditional Cock-a-Leekie Soup are A cock or plump fowl, leeks, prunes, Jamaica pepper (allspice), salt, veal or beef stock or water.
Prunes often feature in recipes for cock-a-leekie soup. However, I decided not to include them in my recipe. I’m keeping it simple and focussing on the two main ingredients: the leeks and the chicken.
Here are the ingredients you will need for my recipe for Scottish Chicken & Leek Soup (Cock-a-Leekie). You only need a few ingredients to make this delicious soup and they are all easily available.
- Leeks
- Chicken stock
- Rice
- Butter
- Oil
What kind of stock (broth) do I need for Scottish Chicken & Leek Soup?
Use a good chicken stock because the stock is key to the flavour of this soup. If I have a roast chicken I make stock with the leftover bones. However, you can buy good chilled chicken stock or use stock pots or stock cubes to make your stock.
What are Leeks?
Leeks are a member of the allium family like onions, garlic and shallots. Leeks have a milder flavour than onions. They grow well in the colder weather of Scotland and are easily available in winter and early spring.
Why do I need to add rice to the Chicken & Leek Soup?
Add rice to help to thicken the soup slightly and make it more filling. You could leave it out or use another grain, like pearl barley although that will take longer to cook.
What kind of rice should I use?
I use long grain basmati rice, but you can use any kind of rice. Some short-grain rice varieties absorb more liquid and this may reduce the overall quantity of your finished soup. If you want to use short-grain rice, use less.
Do I need to add pieces of chicken to the soup?
Serve the soup with or without extra chicken. If you make your own stock from a chicken carcass or chicken legs and wings then save these to add to the soup.
Why do you make the soup in a Slow Cooker?
I make this soup in my slow cooker because if you cook soup at a low heat for a long time and it always improves the flavour. Cook it in your slow cooker and you are guaranteed a low simmering heat.
Slow Cooker cooking is also very convenient and economical. You know you can leave the soup cooking and go and do something else. You can cook this soup slowly on your stove however some of the soup does evaporate, you also have to stay close by to check the soup.
Can I make the soup without a Slow Cooker?
Yes, you can also make the soup in a pressure cooker on High for 10 minutes. Or simmer in a pan on the stove for 30-40 minutes.
Can I make Chicken and Leek Soup ahead of time?
Yes, soup is ideal to make ahead of time. Cool the soup and store it in a lidded container in the fridge, then reheat gently on the stove or in the microwave.
Can I freeze Scottish Chicken and Leek Soup?
I often freeze Chicken and Leek Soup and it freezes really well. Once cooled put it into a freezer-proof container and freeze for up to 6 months. For best results defrost overnight in the fridge before heating in a pan on the stove or in the microwave.

Chicken & Leek Soup is not suitable for vegetarians. However, you can make a similar soup using vegetable stock.
Gluten Free
Scottish Chicken and Leek Soup does not contain any wheat products, so it is suitable for a gluten free diet. As always. please check any stock and rice packets to ensure that they are suitable for your needs.
