1-First Step: Preheat the oven to 400℉ and line a baking dish or sheet with parchment paper for easy cleanup. This gives you a predictable environment for even roasting.

2-Second Step: Cut the butternut squash lengthwise and remove the seeds. Place the squash on a flat surface and use a sharp, sturdy knife. If the squash is very hard, microwave the whole squash for 1 to 2 minutes to soften slightly and make slicing safer.

3-Third Step: Place the squash halves skin side down and flesh side up on the prepared baking dish. This lets the exposed flesh caramelize and collect any seasonings.

4-Fourth Step: Brush the exposed flesh with 1 tablespoon olive oil so it browns evenly. Then sprinkle with 1 teaspoon sea salt, 1/2 teaspoon black pepper if using, and 1 tablespoon brown sugar. The sugar helps the flesh caramelize and adds depth of flavor.

5-Fifth Step: Roast in the preheated oven for 45 to 60 minutes. If your squash is on the smaller side, check at 40 minutes to avoid overcooking. The squash is done when the flesh is very soft and a fork slides in easily.

6-Final Step: Remove from oven and let rest for 5 minutes. Serve as a side dish or scoop out the flesh to cube, puree, or add to salads and soups.
