Cut spaghetti squash in half lengthwise. Scoop out seeds and stringy bits and discard (or save the seeds for roasting).
Drizzle the cut side with oil or spread with butter. Season with salt and pepper.
Place cut side down and bake 40 minutes or just until tender.
Cool 5 minutes. Flip spaghetti squash over and gently run a fork down the squash to separate into strands.
Season with additional butter, salt and pepper if desired.
Notes
Vicky and I made this on January 24, 2020. There was more than enough to go around. We like to cover it with sauce..and sometimes sprinkle with cheese.
