Purple Sweet Potato?
The star of this recipe is, of course, the purple sweet potato. And our key ingredient is not just a pretty face! All sweet potatoes are loaded with nutrients like fiber, vitamin A, B vitamins (especially B6) and vitamin C.
Additionally, the purple sweet potato also contains anthocyanins, which are responsible for its color. The role of these antioxidants in human health isn’t fully clear. However, there are studies emerging that suggest anthocyanins can protect your heart (among other things). And so, it could be a good idea to add more of them to your diet.
How to Make Sweet Potato Soup
This soup starts with a “mirepoix” – the fancy French word for a mixture of onions, carrots, and celery. First, we cook this low and slow until soft and sweet. However, keep the heat gentle because you don’t want too much browning.
When these veggies are tender we add the broth, a handful of the herbs (see the recipe), the apple, and purple sweet potato. The soup is then brought to a boil and quickly reduced to a simmer.
Apple? Yes – we’re glad you noticed that! We added apple to the recipe for a little extra sweetness, instead of just tossing in sugar. It also contributes its own Fall flavor to the soup, which goes really well with the herbs. In other words, the apple complements the other ingredients beautifully.
When the sweet potatoes are soft and all the flavors have mingled, it’s time to blend the soup. The easiest tool for this is an immersion/hand blender. However, a regular blender will do – just be careful moving the hot liquid around.
If your soup is too thick, just mix in a little more stock. Otherwise, if it’s too thin you can return it to the heat and simmer a bit longer. After that, just ladle the purple sweet potato soup into bowls and garnish with herbs – easy recipe right?
