Peel the sweet potatoes and cut in to large chunks. Slice the onion and chili.
Toss the vegetables in oil just to coat the surface. Season with salt, pepper and ground coriander and place on a roasting tray.
Roast the vegetables on 200 C for 35-40 minutes or until nicely brown.
Remove the garlic and put all the other vegetables in a pot together with the coconut milk, chicken stock and curry paste. Bring to a boil and let simmer for 10 minutes.
Blend the soup until smooth and season to taste.
