Preheat oven to 375 degrees F.
Use a knife to poke some holes in the outside of the spaghetti squash, then place spaghetti squash in the microwave and cook for 2 mins to soften skin.
Skin should be softened enough it should be easier to cut the spaghetti squash in half, so cut in half, scrape out seeds, and drizzle both sides with olive oil and season with salt and pepper.
Put on baking sheet and bake cut side down at 375 for 45 mins.
