Roasting pumpkin needs to be at a higher temperature to get some lovely caramelization as it cooks quickly due to its high water content. Adding in some already roasted pumpkin seeds or pepitas at the very end as some lovely crunch to the sweet pumpkin.
RoastedPepitas(pumpkin seeds) that have been shelled and salted
Preheat oven to 450F. Place pumpkin on a rimmed baking tray, in a single layer, do not overlap. If need be use two trays.
Drizzle with olive oil, salt and pepper and the thyme leaves. Bake for 15-20 min. Do not turn. Carefully transfer to a serving dish. Sprinkle with pepitas and thyme sprigs if desired. Serve immediately.
