Easy and healthy sweet potato soup

This sweet potato soup is made with roasted sweet potatoes which give the soup more depth and flavour. The combination of the sweet potatoes and cinnamon blended together in a creamy soup is SO delicious. (Trust me!)

The soup then gets blended up (in a blender or with an emulsion blender, both work fine.) until it’s super smooth and creamy. You can optionally top this soup with some parsley, roasted chickpeas and a drizzle of olive oil.

Health benefits of sweet potatoes

Sweet potatoes are loaded with fibre and nutrients and are the perfect healthy food to enjoy during the Fall and Winter months.

Sweet potatoes are also great for digestion and help promote gut health. They are also loaded with Beta-carotene which is good for your eyesight!

Tips for making this recipe perfectly

  • Cut the sweet potatoes into even cubes. This will ensure that the sweet potatoes all cook evenly when you roast them in the oven.
  • Preheat the pot. If your pot isn’t non-stick, preheating the pot can help prevent the onions and garlic from sticking.
  • Blend to your liking. I enjoy this soup when it’s completely pureed and smooth and creamy. If you prefer a slightly chunkier soup, you can just blend it slightly.
  • This soup freezes well.
