Heat the oven to 450 degrees F and cover a baking sheet with foil. Split the squash in half and scoop out the seeds. Season the squash with salt and pepper and place, cut-side down, on the baking sheet. Roast the squash until very tender, 45 to 60 minutes.
Turn the roasted squash over and shred each half with a fork, turning the flesh into what looks like a yellow boat filled with spaghetti. Drizzle the hot squash with a little extra-virgin olive oil and adjust the seasoning.
Top with lots of your favorite sauce and garnish with shredded cheese. Serve each "boat" on a platter and eat the squash and sauce right from the skin of the squash.
