Preheat oven to 375°F and line baking sheet with parchment paper.

Slice the spaghetti squash in half lengthwise and scrape out the seeds with a spoon.

Rub the cut side of the squash with olive oil and sprinkle with salt and pepper.

Place cut sides down on the baking sheet and roast uncovered for 40-50 minutes.

Remove from oven and let squash cool, cut side up. Pull the flesh away from the sides with a fork to create spaghetti-like strands.
