How to Roast Spaghetti Squash

Adjust oven rack to middle position and preheat oven to 400°F (200°C). Line a rimmed baking sheet with parchment paper and set aside.

Cut off both ends (about 1 to 1 1/2 inches from each end) of the spaghetti squash, so you can just see the opening of the seed cavity. Discard squash ends. Cut squash in half crosswise through its equator, then scrape out and discard seeds and any loose stringy fibers. Drizzle with oil, rubbing all over until both flesh and skin of squash are evenly coated. Arrange squash halves, cut side down, on the prepared baking sheet.

Roast squash until its flesh is fork-tender, 40 to 45 minutes. Set aside to cool slightly, about 10 minutes.

Use a fork to separate and loosen the squash flesh from the skins. Discard skins. Using 2 forks, gently separate flesh into long spaghetti-like strands. Transfer strands of spaghetti squash to a bowl and season with salt and pepper to taste. Toss with butter, extra-virgin olive oil, or sauce of your choosing. Serve.
