All you need is a spaghetti squash and a slow cooker. Just add the uncooked, whole spaghetti squash to the slow cooker, set it to low, and let it cook for three hours. That's it. You don't have to stab it, cut it, or fear for your life anymore.
My slow cooker cooks things very fast, so you might need to cook it longer depending on what you are using. Once it was done, I was able to slice it open with zero problems.
