Variations & Substitutions

👩🏽‍🍳 Tips for the best slow cooker spaghetti squash

Adding a cup of water to the bottom of the slow cooker is essential for creating steam that cooks the squash evenly without drying it out.

  • Pre-cooking the squash in the microwave for 4 minutes makes cutting through easier and reduces cooking time.
  • Place the squash halves cut side up to prevent them from getting too soggy, as they won’t be sitting directly in the water.
  • Start checking the squash at the 4-hour mark. Overcooking can make the strands mushy.
  • Use a fork to fluff and separate the strands while they’re still warm for the best “spaghetti” pasta or noodles texture.

How long does it take to cook spaghetti squash in a slow cooker?

I recommend cooking spaghetti squash on low for total time of 4-6 hours in the slow cooker. The squash should be tender and easily pierced with a fork when it’s done.

Why is my spaghetti squash soggy?

You might have overcooked your spaghetti squash. To prevent this from happening, set your slow cooker to four hours first.
