Line a rimmed baking sheet with parchment paper or tin foil and preheat the oven to 375 degrees.
Rinse off the outside of your squash and then cut it in half from top to bottom. Scoop out the seeds.
Drizzle the inside of both pieces of squash with olive oil and give it a generous sprinkle of salt and pepper.
Place the squash on the prepared pan, cut side down, and add the water to the bottom of the pan. (Just pour it around the squash). Place in the hot oven.
Roast for 40-50 minutes until the squash is easily pierced with a fork or the tip of a knife.
Remove from the oven, allow to cool slightly, then scoop flesh from the skin.
You can serve the squash as is, scooped straight from the skin with a little salt to taste. You can add it to a bowl and mash it with a little butter and a bit of brown sugar, or you can use it like you would any potato, sweet potato, or pumpkin in recipes.

Notes
Since butternut squash can vary in size, you might need to adjust your roasting time accordingly! Keep the temperature the same, but check on the squash frequently.
You might want to wear disposable gloves as you are washing and preparing your squash to avoid any orange color from staining your hands.
Parchment paper makes cleaning up a breeze, so I highly recommend it! You can also use a nonstick baking sheet, but you’ll have a little more scrubbing to do.
Make sure the entire surface of the butternut squash is covered in olive oil. This will help tenderize the squash and prevent moisture from escaping.
