Preheat oven to 220°C (fan-forced). Line a large roasting pan and an oven tray with baking paper. Use a small sharp knife to cut 10 x 3cm-long, 1-2cm deep slits into lamb. Push garlic slices and a rosemary sprig into each slit. Add lamb to prepared roasting pan. Spray with cooking spray and roast for 15 minutes.
Meanwhile, put parsnip, carrot and potato in a large bowl. Spray with cooking spray and toss to coat. Spread pumpkin over prepared oven tray and spray with cooking spray.
Remove lamb from oven. Reduce oven to 180°C (fan-forced). Arrange parsnip, carrot and potato around lamb. Roast lamb and pumpkin for 30 minutes. Spray brussels sprouts with cooking spray and add to pan with lamb. Cook for a further 20-30 minutes or until vegetables are tender and juices run pink when a skewer is inserted into lamb.
Transfer lamb to a carving tray and set aside for 10 minutes to rest. Transfer pumpkin to roasting pan with vegetables and return to oven to keep warm.
