Ingredients for Spicy Sweet Potato Soup
Sweet potatoes – I used five sweet potatoes which totalled 800g in weight. You can get huge sweet potatoes so use less if you are going big.
Other vegetables – There really aren’t many ingredients in this sweet potato soup, just a carrot, some garlic and a stick of celery.
Spices – This is a spicy sweet potato soup so I have opted for Harissa paste (you can even make your own homemade harissa paste here). You could use curry paste instead for a curry spiced soup which works just as well with the flavour of sweet potatoes. Use what you have in the house.
Stock – This is a vegetarian sweet potato soup recipe so I’ve just used vegetable stock. Feel free to use chicken stock if that is what you have available.
The complete list of ingredients and full instructions for making this recipe can be found on the printable recipe card at the bottom of this post.
How to make sweet potato soup
Wash and dry the sweet potatoes and peel them reserving the strips of peel to make the sweet potato crisps to decorate your finished soup.
Chop the carrot, celery and garlic and saute in a pan with a little olive oil for 5 minutes. This is the base for your soup and adds all the flavour.
Add the chunks of sweet potato to the veggies along with the harissa paste and stir well.
Now add your chosen stock, stir, season with salt and pepper to taste and cover the pan with a lid.
Let the sweet potato soup simmer for about 20 minutes till the sweet potato chunks are tender. If you are cooking on an Aga pop the pan into the baking oven for 20 minutes instead.
Using a potato masher squish down the cooked sweet potato chunks till you get the consistency you prefest for yous spicy sweet potato soup.
Of course you can use a stick blender for this if you want a really smooth soup, but I like a bit of texture so I just stick with my trusty old potato masher here.

Remember those potato peelings you put aside at the beginning of this soup making? Well you can be turning them into super tasty crisps while your sweet potato soup is cooking.
Simply spread the peelings out on an oven tray with a little olive oil and salt and pepper and cook for about 5 minutes at 200 degrees C. Keep an eye on them as they burn easily.
