Preheat oven to 200°C (fan 180°C). Arrange pumpkin, carrots, onion, cherry tomatoes, and garlic (cut side up) on a baking tray. Drizzle with olive oil, season with salt, pepper, and sprinkle dried thyme over the top.
Roast vegetables for 25–30 minutes, until tender and lightly caramelized.
Transfer roasted vegetables to a blender or large pot. Squeeze the roasted garlic out of its skins and add in. Pour over vegetable stock and a splash of balsamic vinegar, then blend until smooth.
Stir in coconut milk and simmer gently for 5–7 minutes. Adjust seasoning with salt, pepper, or balsamic vinegar if needed.
Ladle into bowls and garnish with roasted pumpkin seeds, chili flakes, and a drizzle of pumpkin seed oil.
