To cook acorn squash, a common and effective method is roasting it. Here is a summarized step-by-step guide:

1. Preheat the oven to around 350°F to 425°F depending on the recipe choice.
2. Cut the acorn squash in half vertically and scoop out the seeds and stringy bits.
3. Place the halves cut-side down or up on a baking sheet. If baking cut-side down, add a little water to the pan to keep it moist.
4. Roast in the oven for about 35-60 minutes until the flesh is tender and easily pierced with a fork.
5. Optional: Add butter, brown sugar, maple syrup, olive oil, or seasoning like salt, pepper, garlic powder, herbs, or parmesan either before or after roasting.
6. Serve warm as a side dish.

Different recipes adjust the temperature, time, and seasonings for variations like sweet or savory styles, sliced or halved squash, and added toppings like fresh herbs or parmesan cheese.
