Instructions

1. Preheat the oven to 180°C/350°F (160°C/320°F for a fan-assisted oven).
   
2. While the oven is heating, cut the pumpkin into cubes and arrange them on a baking tray lined with parchment paper.
   
3. Roast the pumpkin in the oven for 30-40 minutes (25-35 minutes for fan-assisted ovens), or until tender.
   
4. Once the pumpkin is cooked, remove it from the oven and let it cool slightly.
   
5. Use a blender to purée the pumpkin until smooth.
