Preheat the Oven. Start by preheating your oven to 375°F.
Prepare the Squash. Carefully cut the spaghetti squash in half lengthwise. Scoop out the seeds and discard them.
Season and Roast. Drizzle each half of the squash with olive oil and sprinkle with salt and pepper. Place the halves, cut side down, on a baking sheet. Roast in the preheated oven for about 35-45 minutes or until the squash is tender and the flesh easily shreds into spaghetti-like strands with a fork.Check out this post for more info on How To Cook Spaghetti Squash
Shred the Squash. Using a fork, scrape the flesh of the roasted squash into strands. It will resemble spaghetti!
Top and Serve. Heat your favorite low-carb pasta sauce in a pan. Once heated, pour the sauce over the shredded squash. Top with optional toppings like grated Parmesan cheese, fresh basil, or red pepper flakes. Serve hot and enjoy!
