Preheat oven to 180C. Cut the pumpkin into pieces (remove skin and deseed). Transfer to a large bowl. Add half of the melted butter and toss to combine. Place on a large baking try. Bake in oven for 10 minutes.
Meanwhile, cut apple into wedges and core. Transfer to a large bowl. Add remaining butter and toss to combine.
Place the apple on tray with the pumpkin. Bake for a further 30 minutes.
Reduce oven to 170C. Drizzle some maple syrup (about 1 tbsp) over the pumpkin and apple. Toss to coat. Bake, tossing once halfway through, for a further 10 minutes or until golden and tender.
Garnish with some pumpkin seeds before serving.
