Heat the olive oil in a medium to large pot and lightly saute the onion, garlic, ginger and zest until translucent (approx 2-3 mins).
Add the carrots and stir to combine for another minute. Add the stock and cook for 40 mins or until the carrots are tender.
Blend the soup using a hand blender or food processor until smooth and creamy. Add the maple, juice and seasoning and cook on the heat for a further 5 mins.
Garnish with freshly chopped coriander and serve immediately.
