For a richer flavor, roast the butternut squash before adding it to the soup. Toss the diced squash with olive oil, salt, and pepper, and roast at 400°F (200°C) for 20-25 minutes, or until tender and slightly caramelized. Feel free to adjust the amount of coconut milk to your preference. For a thicker soup, use less coconut milk; for a thinner soup, use more. 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.
