Sweet Potato and Red Chilli Soup (In A Soup Maker)

I include sweet potato in quite a few of my soups. Just like ordinary white potatoes, they create a lovely thick texture, but there is something about sweet potatoes that make the soup have an almost velvety feel to it.

This recipe is super simple with only 4 ingredients (discounting the oil and stock). The sweet potato provides ample flavour to not require a lot more. The chilli adds a nice warming kick to it, I tend to add 2 chillies to my soups, but that does make it quite spicy hot, so if you prefer a milder taste, you might want to keep it at one chilli, with seeds removed.

Sweet Potato and Red Chilli Soup (In A Soup Maker)

Yield: 4


  • 1 tbsp olive oil
  • 800 g sweet potatoes, peeled and chopped
  • 1 onion, peeled and chopped
  • 3 cloves garlic, crushed
  • 1 (or 2!) red chillies, sliced (deseed for a milder taste)
  • 800 ml vegetable stock


  1. Optional: Saute onions and garlic in olive oil for up to 5 minutes.
  2. Add all ingredients to the soup maker. Make sure you remain within the MIN and MAX soup maker levels. Top up with more stock/hot water if required.

If you want a thicker soup increase the amount of sweet potato and reduce the amount of stock. Likewise if you want a thinner soup, reduce the amount of sweet potato and increase the stock.

This was so delicious, and so easy too, I used a red onion and just 1 chilli without the seeds, and it was fabulous, I will definitely be making this again. Thanks Liana

Is it totally OK to not saute items such as onions and garlic etc? I got a soup maker purposely to cut out all that extra faff that's all. Thankyou for the great recipes.

Hi Fiona - yes absolutely fine to skip the saute step - I only include it as my soup maker has that function built in. I'm all for cutting out the extra faff where possible! Hope you enjoy your soup maker :)

I am new to using a soup maker and look forward to trying your recipes. Could you use chilli powder instead of fresh chilli.

Hi Bev - yes you can use chilli powder if you wish, the taste will likely be quite different though as most chilli powders have cumin and other spices in them too. It'll still taste good though! If you make it, let us know how it tastes!
