Cut the squash or sugar pumpkin in half, then scrape out the seeds and stringy bits.
Place each half into a baking dish, cut side up (like in the pictures), then add some water to the bottom of the pan.
Add 1 tbsp butter and 1 tbsp brown sugar into the centre of each half of squash.
Cover each squash side in aluminum foil.
Bake for 1-2 hours. Some take longer than others depending on the density of the squash. Check them at the 1 hour mark to see if the flesh is soft and easy to scrape. You may need to add more water to the bottom of the dish.
After roasting, scrape the roasted squash from the skin, then purée it along with the butter and sugar.
Now enjoy as a side dish or use the cooled purée in your baking.
