One of my favourite parts of Christmas is getting creative with the leftovers and stretching the Christmas flavours on for days. This year, with many plans being changed last minute, households are even more likely to end up with more food than they can consume on Christmas day. However, you can balance out the environmental cost by using your extra food in new and exciting ways, providing food for days - or even weeks! In this post, I suggest a few different options for your leftover creations, catering for different ingredients and levels of difficulty.


Making soup is one of my favourite ways to repurpose leftovers. Not only is soup super easy and delicious, but it is also really good to freeze, providing meals for weeks ahead of Christmas.

When it comes to soup, I am very flexible, adding whatever is in the cupboard in whatever measures I have them. You do not need to hold back - make the most of all the ingredients you have!
