Preheat your oven to 180°C (350°F) / 160°C Fan / Gas Mark 4.
Bring a large, salted pan of water to a boil.
While the water heats, wash, peel, and trim the carrots. If using larger carrots, slice them into uniform pieces.
Carefully add the carrots to the boiling water and parboil for 5 minutes. This step ensures they become tender, not tough, in the oven.
Drain the carrots well and transfer them to a roasting tray.
Drizzle with honey and olive oil, season with sea salt, and toss to coat everything evenly.
Roast for 10-15 minutes, or until the carrots are tender and beginning to caramelise.
While the carrots roast, finely chop the fresh chervil.
During the final 5 minutes of roasting, remove the tray from the oven, sprinkle over most of the chopped chervil, and toss gently. Return to the oven to finish.
Serve immediately, garnished with the remaining fresh chervil for a final burst of flavour.
