Soup Maker Leek and Potato Soup

Today is most definitely a leek and potato soup kind of a day. It’s grey and it’s damp. Since I’ve had my soup maker, I’ve made so many different soup recipes.

I have loved experimenting with a variety of flavours, but sometimes, it’s the traditional favourites that I crave!

Leek and potato soup is a really popular choice, it is one of the most searched for soup recipes in the UK. It requires very few ingredients to create a really delicious tasting soup.

British leeks are usually in season from November until April – a nice long window to really enjoy and appreciate this versatile vegetable! 

How To Make Leek And Potato Soup

The only ingredients I used to make this soup were leeks, potatoes, onion and garlic – and of course some vegetable stock.

I sliced up the leeks, scrubbed the potatoes until clean, chopped them up into small chunks, peeled and sliced the onion, and peeled and crushed the garlic cloves. 

Should I Sauté The Ingredients First?

Leek and Potato Soup Ingredients

This is a question I get asked all the time when making soups. The answer is really down to how you are cooking your soup, as well as personal taste.

As my soup maker has a saute function built into it I do tend to use this feature. It really is as simple as heating up a little oil or butter first and then adding the ingredients to the soup maker. All in one pot, no need for additional pans and washing up. If my soup maker didn’t have a saute function I would likely skip this step more often than not.

Add The Stock 

Once all the ingredients are in the soup maker (or pot if you are making it on a stove), it’s time to add some stock. For leek and potatoes soup I tend to use vegetable stock. Pour it in over the ingredients, making sure it is somewhere between the MIN and MAX lines. I then usually give everything a good stir to make sure no ingredients are stuck to the bottom.

You can also add any chosen seasoning at this stage (salt, pepper etc). Check what’s in your stock first though as you might not need to add a lot, if any.

Cooking Leek And Potato Soup

In a soup maker, all you need to do is choose your preferred setting. I tend to use the smooth function more often than not. This will cook and blend the ingredients, producing a lovely smooth soup after just 21 minutes. If you are making your leek and potato soup in a pot, bring it to the boil and then reduce the heat to a gentle simmer until the leek and potatoes are cooked through and soft.

Making Leek And Potato Soup In A Different Soup Maker

I have made this soup in both the Morphy Richards Soup Maker, and the Ninja Soup Maker. If you are making it in the Ninja – or any other soup maker with a smaller capacity – you will need to reduce the quantities slightly. 

For example, the Morphy Richards is 1.6L in size (the compact is 1L), and the Ninja is 1.4L – so there really isn’t much difference. Either add a little less, or, if you prefer, leave it as it is and get a slightly thicker soup – just make sure you don’t go over the MAX line in any of the soup makers.

How Can I Make Creamy Leek and Potato Soup?

Once the soup has finished cooking, stir in some cream or milk – about 150ml should be enough, depending on how creamy you like it.

Leek and Potato Soup in a Soup Maker

Yield: 4
Prep Time: 5 minutes
Cook Time: 21 minutes
Total Time: 26 minutes

Leek and potato soup in the soup maker is quick and easy to make and is incredibly comforting.


  • 2 medium leeks, sliced
  • 300g potato, peeled and diced
  • 1 onion, chopped
  • 2 cloves garlic, peeled and crushed
  • 1 litre vegetable stock


  1. Prepare the ingredients by peeling the onion and chopping it up, trimming the roots and tops of the leeks and finely slicing, peeling the garlic cloves and crushing and peeling and dicing the potatoes.
  2. Optional: add 1 tbsp. olive oil to either your soup maker (if it has a sauté function), or a saucepan. Gently sauté the onions for 2 minutes, stirring frequently. Add the leeks and garlic and sauté for a further 2 to 3 minutes, until they start to soften.
  3. Switch off the sauté function/transfer ingredients to your soup maker. Add the potatoes to the soup maker.
  4. Add approximately 1 litre of vegetable stock (make sure you stay within the minimum and maximum guidelines on your soup maker)
  5. Stir the ingredients around with a wooden spoon. Set the soup maker off on the smooth setting.
  6. Season according to taste.


Sautéeing the ingredients is optional. I have the sauté function built in to my soup maker so it makes this step much easier. If you don't have this function you can just add all the ingredients to the soup maker if you prefer, skipping step 1.

Different soup makers - I have made this using both a Morphy Richards Soup Maker (1.6L) and the Ninja Soup Maker (1.4L). For different size soup makers just adjust the amount of ingredients slightly to make sure everything fits in.

Should I use 2 stock cubes? As Knorr Vegetable Stock says to dissolve in 500ml of water, or 750ml for a lighter stock. Hoping to try making this soon.
