Spicy Sweet Potato, Red Pepper and Carrot Soup - a hearty low calorie soup with the natural sweetness from sweet potato paired with the spicy kick from a blend of spices making it both flavourful and delicious.

There is nothing quite as delicious as a hearty filling bowl of soup and although soups tend to be made more frequently in the winter, this soup is one I love to make any time of year.
It is great for those batch cooking days too when you want to fill the fridge with some delicious grab and go meals and soups. I like to batch cook from all these delicious Soup Recipes to ensure my freezer has plenty of meals to grab for busy days.

I like to get all the ingredients ready in advance and then this is a super quick and simple recipe to cook all in one pan.

Substitutes for Sweet Potato
A great substitute for sweet potato in recipes in butternut squash, it has a similar colour, flavour and texture but it lower in carbs and calories, so a great option if you want to reduce the calories a little more in a recipe.
White potato can be substituted for the sweet potato if you don't like the sweetness of sweet potato, but I find that little bit of sweetness balances the spices in the recipe.
Smooth vs Chunky Soups
Many people like there soup to be completely smooth and others prefer a more chunky soup. I am definitely one of the later. I just find a soup is more hearty and filling if you can see chunks of the vegetables. It can be a bit too much like a puree or baby food when it's completely smooth.
If you want your soup really smooth then a counter top blender will be you best option for blending, but if you like to keep some pieces of the vegetables in the soup then a stick immersion blender is perfect and they are very reasonably priced too. I just give it a rough blend to thicken the soup, but not for too long that it blends everything in the pan.
Toning down the Spice Level in a Recipe
Not everyone likes spicy food but still may like the look of a recipe and want to give it a try.
The only ingredient that adds the heat to this recipe is the cayenne pepper, so either use a lot loss or omit all together if you don't like food too spicy. Be careful with the paprika you use also. For this soup I use just regular paprika (it's also known as sweet paprika) - smoked varieties can be hot, so will add some heat to the dish too.
If however you add all the cayenne and find the spice level too much for you, adding a little acidity like lemon or lime juice can tone down the heat, or a little sugar/sweetener or if you like creamy soups, a spoon or two of yoghurt or a little drizzle of coconut milk.

Variations and Optional Add-ins
This soup is delicious just as it is or some lightly buttered wholegrain bread, but I do occasionally switch it up just to make it slightly different.
For example if I want to add some protein, these are some great options to stir in to the soup:
- Cooked Sausage (choose a low calorie brand you enjoy)
- Cooked Leftover Chicken or Turkey
- Crumbled Feta
- Grated Cheddar
- Cooked ground meat (pork, turkey or chicken - I find beef a bit too rich for this soup)
or if I want to keep it meat free but make it a bit more filling I may add one of the following:
- Cooked Quinoa
- Cooked Rice
- Cooked Pasta (small varieties are best - like orzo, ditalini or stelline, but any shape is fine)
Then you can also make this into a creamy soup by adding the following:
- 120g of light cream cheese
- swap out 1 cup of the stock for 1 cup of coconut milk (light is lower in calories but not as thick)
- swap half the stock for 2% milk, but you may wish to add a little cornstarch to thicken (around 2 tablespoons) or blend some of the vegetables for your desired consistency)

Freezing
This soup is great for batch cooking and freezing. To freeze I recommend freezing in one portion containers, that way you can just take out what you need.
To reheat, fully defrost in the fridge and then gently heat in a pan over a low heat until heated through or you can reheat in the microwave.
Sometimes soups will thicken as they cool and I do like my soups to have a good amount of broth, so if it is too thick, I will often just add in some more stock to loosen it all a bit when I reheat.

Made this in my instant pot. 10 minutes on soup setting then just left it to release naturally. The only ingredient I omitted was cayenne pepper. It was amazing. Definitely will make it again. Perfect winter soup.

I made this soup for my daughter in law, she loved it so much I’ve had to make again. She takes it to work for her lunch. It must cost less than £2.00 to make economical and healthy it’s a winner.
