Preheat oven to 220C/425F (standard) or 200C/400F (fan).

Cut carrot on the diagonal into 4cm / 1.75” lengths. Halve thicker end so they are all roughly the same width.

Toss in a bowl with sugar, butter, garlic, oil, salt and pepper. Pour onto tray, spread out.

Roast 15 minutes. Toss, then roast a further 10 minutes until soft and caramelised on the edges with plenty of glaze left on the tray.

Toss carrots in the glaze, sprinkle with parsley if using. Serve warm.
