Creating delicious roasted butternut squash is simple. Just follow these easy steps:

1. Preheat the Oven: Begin by preheating your oven to 400°F (200°C).
2. Prepare the Squash: Carefully cut the butternut squash in half lengthwise and scoop out the seeds. You can also peel and cube it if preferred.
3. Season the Squash: In a large bowl, mix the squash with olive oil, salt, black pepper, and any optional spices, like cinnamon or rosemary.
4. Arrange on Baking Sheet: Place the seasoned squash, cut side down, on a baking sheet lined with parchment paper for easy cleanup.
5. Roast: Put the baking sheet in the preheated oven and roast for about 30-40 minutes until the squash is tender and caramelized. You can test for doneness by inserting a fork into the flesh.
6. Cool and Serve: Once roasted, remove the squash from the oven and allow it to cool slightly before slicing or scooping out the flesh for serving.

These straightforward steps will guarantee success, yielding perfectly roasted butternut squash every time!
