Preheat the oven to 400°F / 200°C (180°C fan-assisted) and line a baking sheet with parchment paper.
Cut the spaghetti squash in half and remove the seeds and soft strings with a large spoon. Place the squash cut side down on the prepared baking sheet and bake for 30-40 minute, or until lightly browned on the outside, fork tender, but still a little bit firm. Keep in mind that the exact cook time will vary based on the size and water content of the squash.
