01 - Preheat oven to 425°F. Line a baking sheet with parchment paper.
02 - Spread carrots, onion, and garlic cloves on the prepared baking sheet. Drizzle with olive oil, sprinkle with cumin, coriander, salt, and pepper. Toss to coat evenly.
03 - Roast for 25–30 minutes, until carrots are tender and starting to caramelize.
04 - Transfer roasted vegetables to a large pot. Add fresh ginger and vegetable broth. Bring to a simmer over medium heat. Cook for 10 minutes, allowing flavors to meld.
05 - Remove from heat. Using an immersion blender (or in batches in a countertop blender), puree soup until silky smooth.
06 - Stir in coconut milk and adjust seasoning with salt and pepper. Gently reheat if needed.
07 - Serve hot, garnished with fresh herbs, extra coconut milk or yogurt, and toasted seeds if desired.
