How to make soup from leftovers

Do not let your leftovers go to waste when you can transform them into a tasty meal in minutes.

Chef Paul Thinus Prinsloo of Waterkloof Estate, who is also Africa, and the Middle East regional winner of S.Pellegrino Young Chef 2019 shares tips on how to make soup from leftovers. 


Instead of adding all your meat to a stew, keep some aside to prevent wastage and make a soup from the rest.

Pasta and grains 

Don’t mix all of the pasta when making mac and cheese if you know it is going to be too much, keep excess pasta and use it for a bowl of Minestrone soup.


Potatoes such as a mash can be used in soups for flavouring and thickening.

Raw vegetables 

Raw vegetable offcuts can be stored and used as the base for your soup. 

Leftover stew 

The leftover stew can be reused, by adding more liquid and veggies to the mix or as a start to a soup. 

Here is a quick recipe that you can try.
