Leek & Potato Soup | Slimming World Friendly Recipe

slimming world Leek & Potato Soup recipe

I LOVE leek and potato soup and luckily I had a few spare potatoes and a leek hanging around! I just had to make my own Slimming World friendly Leek and Potato soup!

Traditional recipes are made with double cream, but mine is equally as creamy without it.  I like my soups to be super smooth but you can blend it to any consistency that you like.

I used 1 tablespoon of horseradish sauce for extra flavour which is 1 syn. The soup easily makes about 6 large bowls so I didn't syn it when just having the one bowl.

If you feel more comfortable syning it, then do.

If you want to add a little extra syn to your leek and potato soup, you can find horseradish sauce online at Ocado along with the other ingredients needed for this dish. Shop using Ocado voucher codes and enjoy this flavourful feast for less
