Thai-Inspired Roasted Carrot and Sweet Potato Soup

Thai-Inspired Roasted Carrot and Sweet Potato Soup

Soup is of course to be enjoyed no matter the time of year, but during the cold winter months, soup is one of the most comforting meal options. This creamy carrot and sweet potato soup makes good use of winter root vegetables to make a soup that's both hearty and warming, which is just what we want when the cold winds are howling outside.

Roasting the carrots and sweet potatoes enhances their natural sweetness (and gives you an excuse to turn on the oven if it's particularly cold outside). But it's the Thai-inspired hot and aromatic seasonings — chilies, lemongrass, red curry paste, as well as the coriander seeds that are roasted with the vegetables — that give this soup its heat, balance and allure. Coconut milk and the addition of some almond butter make this pureed soup especially creamy and thick, with the pleasing contrast of crunchy toasted tamari almonds should you choose to include those as a garnish, which I highly recommend. The soup does have a spicy kick, but it's warming without being overpoweringly so.

Add more stock as needed.

  • Discard the lemongrass stalks, stir in most of the cilantro, reserving some for garnish, and purée the soup with an immersion blender or in batches in a countertop blender. Stir in the lime juice, salt and pepper, and adjust for seasoning.

  • Serve hot garnished with cilantro and roasted tamari almonds if desired.
