Wash carrots. In a bowl whisk the olive oil and cumin.
Place carrots in an ovenproof dish. Drizzle over the olive oil and cumin dressing.
Place carrots in a pre-heated, medium oven and roast for 30 minutes (turning over once).
Remove from oven and stir in the orange juice, orange zest and honey. Toss all ingredients lightly. Return to oven and cook for another 30 minutes until nicely browned in colour.
