1 Preheat oven to 200°C/180°C fan-forced.

2 Combine thyme, crushed garlic and oil in a bowl. Rub all over lamb. Place onion in a large flameproof roasting pan. Top with lamb. Season with salt and pepper. Bake for 20 minutes or until golden. Reduce temperature to 150°C/130°C fan-forced. Add half the stock, vinegar and 1/2 cup water. Bake for 4 hours or until very tender.

3 During the final 30 minutes of lamb cooking time, place parsnip, potato and halved garlic in a large saucepan. Cover with water. Bring to the boil over high heat. Reduce heat to medium-low. Boil for 15 minutes or until vegetables are tender. Return to pan over low heat. Mash until well combined. Add milk and butter. Mash until smooth and combined. Season with salt and pepper.

4 Transfer lamb to a plate. Strain cooking liquid from roasting pan, reserving onion. Discard liquid. Return onion to pan. Place pan over high heat. Add wine. Bring to a simmer. Add remaining stock and sugar. Reduce heat to medium. Simmer, stirring occasionally, for 5 minutes or until reduced slightly. Season with salt and pepper.

5 Combine parsley, lemon zest and chilli in a bowl. Shred lamb. Divide mash and lamb among serving plates. Drizzle with onion gravy. Sprinkle with parsley mixture. Serve with broccolini.
