    What You Need

    Just 7 basic ingredients is all you need to make our Thermomix Potato & Leek Soup!

    Note: Please scroll to the recipe card at the bottom of the post for ingredient quantities and the full method.

    The ingredients for potato and leek soup.
    • leeks - cut off the green part of the leeks and use the white section
    • onion - choose a brown or yellow onion
    • butter - unsalted or salted butter is fine to use in this recipe
    • garlic - mince your own cloves of fresh garlic or use pre-minced garlic in a jar
    • potatoes - for best results choose a variety of potato that is suitable for cooking and mashing (ie. brushed potatoes). Peel and chop into large chunks.
    • chicken stock liquid - use store-bought liquid chicken stock or make your own by mixing 1 teaspoon of powder stock through every 1 cup of water. Alternatively, you can use your own homemade chicken stock paste.
    • cream - choose a cream that is suitable for heating (like a cooking cream or a thickened cream).

    Step By Step Instructions

    Note: Please scroll to the recipe card at the bottom of the post for ingredient quantities and the full method.

    Step 1 - Chop The Onion & Leeks

    Mix the leeks and halved onion until finely chopped. Scrape down the sides of the bowl occasionally.

    Step 2 - Saute

    Add the butter and garlic and saute until soft.

    Step 3 - Add The Potatoes

    Add the potatoes and cook for a further 5 minutes.

    Potatoes peeled and chopped in a stainless jug.

    Step 4 - Cook

    Add the liquid chicken stock and season with salt and pepper.

    IMPORTANT NOTE: Do NOT exceed the MAX line at any stage. Use less liquid stock if you are nearing the MAX line.

    Cook for 20 minutes. Remove the MC before cooking, but place the rice basket over the whole to catch any splatters.

    Allow the soup to cool slightly before pureeing (do not attempt to puree while the soup is very hot as this can be very dangerous).

    Add the cream and mix through gently.

    Serve with crispy bacon (optional).

    Expert Tips & FAQ

    What happens if I've reached the MAX line and still have extra stock to add?

    It's important that you never exceed the MAX line. If you're nearing the line, simply omit the excess liquid stock you have.

    Pureeing the soup

    Remove the lid and allow the soup to cool for a few minutes before replacing the lid and pureeing. Start off on Speed 1 before very slowly increasing to Speed 6. If the machine starts to shudder or shake, go back down to Speed 1 and increase ever so slightly.

    Storing

    Store this soup in an airtight container in the fridge for up to 3 days.

    Freezing

    Freeze in an airtight container for up to 3 months.

      I have made this 6 or 7 times now and this is super easy and such a crowd pleaser. Even my very fussy non vegetable earring child loves and requests it every week!
      Adding bacon or chicken bacon makes it and heated soup buns.
      Delicious!
