For an extra layer of flavor, consider roasting a few sprigs of fresh rosemary alongside the squash and sweet potato. Garnish options include a swirl of coconut cream, a drizzle of high-quality olive oil, toasted pumpkin seeds, or a sprinkle of red pepper flakes for a touch of heat. The soup can be stored in an airtight container in the refrigerator for up to 3 days. Reheat gently on the stovetop or in the microwave.
