This simple recipe for how to cook a whole spaghetti squash in the slow cooker is the best set-it-and-forget-it hack -- you'll never go back to roasted spaghetti squash!


  • 1 large spaghetti squash, about 3 pounds
  • 1 cup water


  1. Rinse off your spaghetti squash, poke it a few times with a fork or sharp knife, and set it in the bowl of your slow cooker.
  2. Add one cup of water to the bottom of the slow cooker.
  3. Cover and cook on high for 3 to 4 hours or on low for 4 to 5 hours, or until a fork easily pierces the skin of the squash.
  4. Remove from the slow cooker, and place on a cutting board.
  5. Cut in half width-wise with a sharp knife, and remove the stem.
  6. Use a spoon to scrape the seeds from the center.
  7. Use a fork to scrape the flesh so that it becomes "spaghetti."
  8. Serve however you like.
