Preheat your oven to 200°C (400°F) and line a baking sheet with parchment paper.
Toss the chopped carrots, sweet potatoes, and parsnips in olive oil and sprinkle with curry powder (or smoked paprika), salt, and pepper.
Roast the vegetables in the preheated oven for 25–30 minutes, or until tender and caramelized.
In a soup pot, combine the roasted vegetables with vegetable broth and bring to a simmer over medium heat (or use water with a bouillon cube for a quick substitute).
Stir in the coconut milk and ground ginger, and cook for an additional 5–10 minutes to blend the flavors.
Use an immersion blender to blend the soup until smooth, or transfer the mixture to a blender in batches.
Taste and adjust the seasoning with more salt, pepper, or ginger if needed.
Serve hot, garnished with a drizzle of coconut milk, a sprinkle of fresh cilantro, or a few toasted pumpkin seeds for added texture.
