For the full list of ingredients and comprehensive instructions, please see the recipe card at the end of this post. Before you scroll, there’s important stuff in the blurb 👍

This soup is perfect on the Slimming World Extra Easy Plan as it’s packed with carrots, celery, onions and tinned chopped tomatoes. All those great speed foods to help with your weight loss.

Syn Free Speedy Tomato Soup

It’s ideal for a quick lunch, and the ingredients can be found in any Slimming Worlders cupboard! If you’ve been following Slimming World for a while you’ll know you always have a cupboard full of chopped tomatoes and a fridge packed with onions, celery, potatoes and carrots.

Speaking of chopped tomatoes, we like to Cirio as they aren’t watery at all, unlike some other brands. They make a variety of different tinned tomatoes from run of the mill chopped, to baby cherry or plum and even tomato fillets.

Syn Free Speedy Tomato Soup

This recipe is the Thermomix version, but it will also work in a soup maker. However, if you don’t have either of these gadgets then it works just as well in a pan on the stove, and you can find that recipe here.

Whenever we need to replace oil in cooking we use Frylight. Perfect for everyday frying and cooking, it delivers exactly one calorie per spray, which makes it Syn free! The Sunflower or Rapeseed Oil flavours are ideal for this Syn Free Speedy Tomato Soup recipe.
