Preheat your oven to 400ºF. Line a baking sheet with foil or parchment paper, then set aside.
Cut your spaghetti squash in half lengthwise. To make it easier to cut, pierce the flesh of the spaghetti squash with a knife, then microwave it for about 2 minutes.
Once your spaghetti squash is cut lengthwise, scoop out the seeds.
Coat or spray the skin and flesh of your spaghetti squash with olive oil and lightly season with salt and pepper.
Place your spaghetti squash, flesh side down, on the lined baking sheet.
Bake for approximately 25-40 minutes, until the edges are slightly browned. Remove from oven once tender to fork.
Once cool enough to handle, scrape the squash lengthwise to form spaghetti-like strings. The strings should fall off the squash easily, if cooked thoroughly. Enjoy!
