Thai Roasted Sweet Potato Soup

5 from 2 votes

Enjoy a spicy and sweet Asian-inspired soup.

The sweet, exotic flavor of this soup will make you want to sip it until the last drop is gone from your mug or bowl! With coconut milk and vegetable broth as its base, this soup recipe eases digestion and feels light and refreshing, even as it warms and comforts. Asian-inspired soup recipes are a fun twist on the same old chicken noodle and vegetable soups we’ve been eating since childhood. And for a soup that detoxifies even as it pleases the palate, a dose of cumin and the addition of ginger and lemon are perfect, due to their health benefits and detoxifying effects.

Sweet potatoes have a high nutritional value, as they are complex carbohydrates, which are high in fiber and low on the glycemic index. Plus, they contain high amounts of beta-carotene, an antioxidant which is important for the health of our eyes and skin. If you choose sweet potatoes with darker orange flesh, then you’re getting an extra dose of beta carotene. And the health benefits of this soup don’t end there. Lemon is full of fiber and antioxidants, and is rich in vitamin C, a well-known immune booster. Ginger is packed with antioxidants, and has been used medicinally for centuries to aid in digestion and ease inflammation in the body.

Enjoy this soup on its own, or add a bit of brown rice. You may even want to add a vegetable side such as bok choy or broccoli to amp up the health quotient. And it’s perfect as an appetizer at any dinner party. Your guests won’t believe how simple it is to prepare.

  1. Made this yesterday, omitted the lemon juice as didnt have any in store cupboard and it was lovely. Served with a crusty wholemeal roll. Even my husband wants seconds!

  2. Love the site, what can I use as a substitute for the coconut milk, I am allergic to coconut but would like to incorporate this soup into the 3 day soup detox

  3. Could you add the onion to the sweet potatoes and roast them? Just to make it a step easier. Would 30 minutes in the oven for onions be to long?

    1. I quartered the onions & roasted them right along the sweet potatoes. Set the timer for 15 minutes to turn the sweet potatoes & the onion was done

  4. Thank you for sharing these lovely recipes n good ideas

    The soups are all delicious n light and filling.
