Heat oven to 400 degrees, prick squash with fork, place in a baking dish and bake uncovered about 1 1/2 hours or prick squash and boil in large pot for about an hour till soft. Cook the spaghetti and drain. Cut squash lengthwise; remove seeds and fibers of one half; save the other half for another time. Remove the spaghetti-like strands with 2 forks.
