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.

Speaking of tinned tomatoes, we like to use Cirio, as they aren’t as watery as some other brands.

Really versatile, just throw it in a pan or soup maker!

If you have a Thermomix, we have a version for you 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.

  1. I made this and used sweet potato instead and added a pinch if chilli flakes, it gave it a nice sweetness with a hint of heat. Even my husband was impressed.

  2. Add celery as speed.Gorgeous, even the kids love it, added crusty bread as a side for hubby, not a slimming world fan, but loving the recipies!

    1. Hi Jo
      No, this isn’t that recipe…it’s better! I think that one has baked beans and tinned carrots etc. plus 3-4 pickled onions, but it’s not one of our recipes.

  3. Hi again, yet another success. Feeling a bit chilly on this bank holiday Monday and overdid the syns a bit yesterday so thought soup! Just finished blending it and its lovely. Look forward to having it later. You are certainly challenging me – there must be one of your recipes I try that I don’t like!! Well done and thanks.
