Roast the Squash:
Preheat oven to 400°F (200°C). Halve and seed the squash. Drizzle with olive oil, then roast for 40-45 minutes.
Sauté the Veggies:
In a pot, heat olive oil over medium heat. Add chopped onion and carrots, cook until soft (about 8-10 minutes).
Blend the Soup:
Scoop roasted squash into the pot. Add vegetable broth, cumin, nutmeg, salt, and pepper. Stir and bring to a simmer.
Puree:
Use an immersion blender or transfer to a blender. Blend until smooth and creamy.
Finish with Coconut Milk:
Stir in coconut milk. Adjust seasoning as needed.
Serve:
Ladle the soup into bowls. Garnish with fresh herbs, or a drizzle of coconut milk for flair.
