Preheat oven to 400˚F and line a large baking sheet with parchment or foil.
Using a shark kitchen knife, cut the spaghetti squash in half lengthwise. If difficult to cut, poke a few holes with a fork into the skin and microwave for 3-4 minutes to soften.
Using a large spoon, scoop out the seeds and scrape away some of the stringy flesh.
Lightly brush the inside of the squash with the oil and sprinkle with salt. Place cut side down on the baking sheet and transfer to the oven.
Bake the squash for 45 minutes to 1 hour or until the insides can easily be shredded with a fork.
