Preheat the oven to 400°F (200°C).

Carefully cut the spaghetti squash in half lengthwise using a sharp knife.

Scoop out the seeds and discard them.

Drizzle the inside of each half with olive oil, and sprinkle with salt and pepper.

Place the squash halves cut-side down on a baking sheet.

Bake in the preheated oven for 30-40 minutes, or until the flesh is tender and can be easily shredded with a fork.

Remove the squash from the oven and let it cool for a few minutes.

Using a fork, scrape the flesh of the squash to create 'noodles'.

Serve immediately with your favorite sauce or toppings.
