This hearty sweet potato, lentil and tahini soup is perfect for cold winter weather. Warmly spiced and comfortingly creamy as well as vegan!
It's still soup weather out there and after my success with carrot soup, I was eager to experiment more with tahini in soups. The vegetables were basically what I had left in the fridge so could easily be changed for whatever you have. I think aubergine would be fantastic in this soup.
It's amazing that just a little bit of tahini makes the lentils taste really creamy. I know it doesn't look that pretty or appetizing in the picture, but if you like lentils and tahini then I'm sure you would love this. For a slight variation peanut butter would work really well too and probably any nut butter.
Ways to adapt this tahini soup
The recipe below is really a rough guide only. When I make soups I tend to throw in as much of each vegetable as I have or feel like using.
The spicing also varies. If you feel like making this super hot and spicy then please do. Just add more chilli peppers or more curry powder. You can even use a spice paste instead of the curry powder.
The same goes for if you don't want a really hot soup. Depending on how hot you like it you can remove the seeds from the chilli pepper or even remove it altogether.
Can you swap the red lentils for green or brown ones?
I used red lentils in this soup and they are brilliant as they break up as lot and help to thicken the soup. You can certainly use a green, brown or puy lentils instead but the soup will be different. They don't break down in the same way that red lentils do and so they won't help to thicken the soup.
However, it will still be a really tasty soup.
Can you batch cook this tahini soup?
Like most soups, it's very easy to increase the quantities of this sweet potato and lentil soup and make a larger batch.
Storing and Freezing
If you do make a large batch, just store the remainder in the fridge or freeze it in individual portions.
It will keep well for three days in the fridge or three months in the freezer.
You can then reheat it on the hob or in the microwave.
