Spiced Sweet Potato Soup – easy vegetable soup with a flavour of Morocco

This Spiced Sweet Potato Soup brings together my love of home-made vegetable soup with my love of Moroccan food. It is not a Moroccan recipe but uses spices used in North African stews or tagines. One of the reasons that I particularly like Morocan food is the combination of savoury and sweet ingredients (think Lamb Tagine with Apricots) and its gentle use of spice.

This very simple soup has all these elements. The sweetness of the sweet potatoes provides the perfect vehicle for the spices. Cumin, cinnamon and turmeric provide an exotic and warming note. If you want your soup to have a bit more heat, you can add some cayenne to the mix. I generally add half a teaspoon but you can either leave it out altogether or add more (although I wouldn’t go over one teaspoon) to give the soup a bit more heat. If you don’t have any sweet potatoes to hand, you can use butternut squash or pumpkin as alternatives.

Although I make this soup all year around, I particularly like to make it in January and February. Where I live, these are generally cold, rainy months. A bowl of tasty, healthy soup, sweet and savoury flavoured with gently spices is just what I crave. Not only does this soup taste good, it also looks cheerful with its rich orange colour. I eat it during the cold, English winter and dream of  Marrakech.

Other home-made soup recipes

I have lots of easy, vegetable soup recipes. If you like this Spiced Sweet Potato Soup, you might like some of the others. All my soups are vegetarian and all can be made vegan by substituting animal fats, such as butter, for vegetable fats. Some of them are pretty simple such as Fennel Soup or Jerusalem Artichoke Soup and showcase a single vegetable. Others combine vegetables which have complimentary flavours such as Curried Parsnip and Apple Soup, Celeriac and Apple SoupMushroom and Chestnut SoupPumpkin and Sweetcorn Soup or Leek and Potato Soup. A few have more unusual combinations of flavours such as Beetroot Soup with Coconut or Butternut and Peanut Butter Soup. I also have a few chilled soup recipes, which are fantastic cold in the summer, but can also be served warm such as Asparagus and Pea and Tomato.

Dukkah – an easy and versatile ingredient

I sprinkle a bit of home-made dukkah on the top of this soup. If you would like to make your own version of this versatile nut and spice mix, have a look at my easy dukkah recipe. It think it looks good as decoration on top of my soup but it also adds an extra punch of spicy flavour and fantastic crunchy texture. Dukkah is a traditional North African nutty roasted spice mix which can be used to add flavour and texture to all kinds of dishes. You can buy it ready-made but truly it is far better when you make it at home and it is extremely easy to make. If you are interested in making your own

    1. Thank you so much. I agree no extra sugar is needed as sweet potatoes have a great natural sweetness. ????
