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

Sweet potato and red chilli soup is packed with flavour with the combination of the sweetness of the sweet potato balancing out the heat of the red chillies.

Best of all, it’s quick and easy to make in a soup maker so that you can have a bowl of piping hot soup in no time!

What You Need To Make This Soup

As with many soup maker recipes, you can be flexible with the measurements and switch ingredients depending on what you have available.

6 sweet potatoes, 1 onion, 3 garlic cloves, 2 red birds eye chillies and 1 vegetable stock pot

Sweet Potatoes

You will want to use between 600g and 800g of chopped sweet potatoes – the exact amount will depend on which soup maker you are using.

I have made this soup in a Morphy Richards Soup Maker and a Ninja Soup Maker. The Morphy Richards is slightly bigger in size and so can fit 800g of sweet potatoes in; for the Ninja, the capacity is less, so aim for around 500g – 600g, depending on how thick you like your soup.

Onion & Garlic

I added 1 small onion and 3 cloves garlic. I just added the onions quartered with the whole peeled garlic cloves to the Ninja and pressed the chop button.

You can optionally saute them if your soup maker has this function – I find myself sauteeing less these days, and I’m not noticing a huge difference in taste.

Red Chillies

The number of chillies you add will depend on the chilli variety and how hot you like your soups. Most recently, I used Birds Eye Chilli, a hotter variety, so I only used one, I left the seeds in, and it was the perfect level of heat for me. You might prefer more or less.

I added one vegetable stock pot directly to the soup maker and then added hot water to the maximum line.

Making The Soup (In A Soup Maker)

prepared ingredients for soup - peeled and chopped sweet potatoes, quartered raw onion, 3 peeled garlic cloves and a sliced red birds eye chilli

Prepare all the ingredients by peeling and chopping them. Make sure the sweet potatoes are chopped fairly small so that the soup maker can cook them all the way through.

Peel and quarter/chop the onion and peel the garlic cloves.

You can either crush or thinly slice the garlic cloves – or, with a Ninja Soup Maker, put them in whole with the quartered onions and use the ‘chop’ function to slice them.

Carefully slice the red chilli, remembering to wash your hands well afterwards!

Add the sweet potato, chilli and vegetable stock pot before pouring hot water up to the line.

Set the soup maker off on smooth.

Serve and season according to taste.

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.

Liana Green

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!
