01 - Preheat the oven to 400°F. Toss the pumpkin cubes with 1 tablespoon of olive oil and spread evenly on a baking sheet. Roast for 20 to 25 minutes until golden and tender.
02 - In a large pot, heat the remaining olive oil over medium heat. Add the onion, garlic, and carrot, sautéing until softened, about 5 minutes.
03 - Add the roasted pumpkin, cumin, nutmeg, black pepper, and a pinch of salt. Stir for 2 minutes to toast the spices and blend the flavors.
04 - Pour in the vegetable stock and bring to a boil. Reduce the heat and simmer for 10 minutes until all vegetables are fully tender.
05 - Remove the pot from heat. Use an immersion blender or transfer the soup in batches to a countertop blender, puréeing until completely smooth.
06 - Stir in the coconut milk and reheat gently over low heat. Adjust seasoning with salt and pepper as needed.
07 - Ladle the soup into bowls and serve hot, garnished with fresh herbs and roasted pumpkin seeds if desired.
