This fragrant Sweet Potato, Walnut and Sage Soup is smooth and creamy whilst being low fat & dairy free. The walnuts counter the sweetness of the sweet potatoes with their earthiness, whilst also adding a subtle nutty texture.
Oh yeah. Are you sold yet?
This soup has become a firm favourite in our kitchen already. Even Jonny loves it and he’s not quite as keen on fruit n veg as I am :) 
It was also good to put my Foothie power blender through its paces, although it ground the walnuts to a fine grain within seconds! Actually, if I’d have blitzed them any longer they would have turned into walnut butter.
Hmmm, walnut butter…?
Obligatory soup-in-a-blender shots coming up…
Like magic innit? Anyway, as far as I’m concerned, this soup recipe is good enough to become a family heirloom, so please feel free to pass it onto your Grandchildren with my love ;)

PS Are you nuts about soups? If so, try out this Broccoli & Almond one I made way back in 2011. Just no laughing at the photo’s, OK? ;)
Sweet Potato , Walnut & Sage Soup
- 850 g sweet potato peeled & cubed
- 1 onion chopped
- 1 litre water
- 1 stock cube
- 50 g walnuts ground
- 2 teaspoons dried sage level
- Cook the sweet potato and onion in the water with stock cube until soft.
- Meanwhile blitz the walnuts in a power blender until finely chopped, then pop them in a small bowl to one side.
- Pour the veggies into the blender and add the sage. Whizz together until smooth, the pop the walnuts back in. Give them a little blast to mix the walnuts evenly through the soup.
- Pour back into the pan and add enough boiling water from the kettle until the soup is the consistency you like.

This looks great, Sweet potaoe can be a little too sweet for me but the walnuts would definitely tone that down. Delicious! GG
Jane Sarchet says
I am SO proud of this one GG, the three flavours really do complement each other perfectly.

You know, this is perfect timing because I have sweet potatoes in the cupboard and not much idea what to do with the rest of them. I really like sweet potatoes but don’t often buy them so when I saw some rduced I bought lots. This looks like a lovely idea =)
Julie's Family Kitchen says
Great flavours Janie. I love that you’ve included walnuts, I’d never have thought of that. Looks absolutely scrummy.
Jane Sarchet says
Thanks Julie, I am ridiculously proud of this one! I also made a Broccoli & Almond one in the past was fab too :)

Liz Berrill says
Hi going to make this soup as has grown my own sweet potatoes this year and had bumper crop. I also have fresh sage, if I use the fresh sage instead of dried what quantity should I add and will it need cooking first or just put in fresh into blender?
