Really Easy Slow Cooker Leek and Potato Soup Recipe


My absolute favourite homemade soup is Jamie Oliver’s leek and potato soup from his Ministry of Food book.

This is my version of potato and leek soup, using the slow cooker as I find it saves time and doesn’t leave me with a huge soup pan with onions stuck to the bottom to wash up 🙂 I am a huge fan of my slow cooker and have found so many amazing recipes for it since stumbling upon the crockpot365 blog.

This soup makes loads and it freezes and reheats really well so I always try and keep a stock of it in the freezer. Really yummy and warming with some nice crusty bread!

Leek and potato soup cooked in the slow cooker



2 carrots

2 potatoes (about 500g if you want to be precise)

2 leeks

2 onions

2 cloves of garlic

2 lites vegetable stock (I made mine using 2l boiled water from kettle and 4 Knorr stock pots)



1) Peel and chop all the veggies and garlic.

2) Bung it all in the slow cooker with the stock.

3) Cook on low all day (6-8 hours) or on high for 4-6 hours. Check your veggies are all soft before the next step.

4) Blend the soup with a hand blender. Season with salt and pepper to taste.

5) Serve or save for later.

  1. Please could you tell me what is 21 referring to for the vegetable stock ? Really would like to try this recipe . Sounds easy but yummy ……

    • Hi Sharon – sorry it was 2 and a letter L for two litres but the font made it look like 21. Its 2 litres of veg stock – sorry about that – have amended now, L x
