  • Instant Pot or Electric Pressure Cooker
  • Pairing knife
  • Steamer basket for Instant Pot (optional)


  • 1 4 lb Spaghetti Squash
  • 1 cup water


  • Pierce the squash a dozen times or more with the pairing knife. Cuts should be ½ inch.
  • Pour the water into the inner pot of the instant pot.
  • Place the steamer basket or trivet in the inner pot.
  • Put the whole spaghetti squash in the basket.
  • Cook on high pressure for 20 minutes.
  • Use quick release by carefully moving the sealing knob to the vent position allowing steam to release.
  • Remove the cover, and let the squash rest for at least 10 minutes before cutting into it.
  • Cut in half, remove seeds, and shred with a fork.



  • 1 cup of water is for a 6 qt instant pot, if using an 8 quart, then use 1 ½ cups of water.
  • For Al Dente' cook for 15 minutes. For a more tender result, cook for 20 minutes.
  • I used a four pound squash, and it just fit. You can certainly use a smaller one.
  • Using a steamer basket makes removing the hot squash a breeze! If you don't have a steamer basket, be sure to place the squash on the trivet that your instant post came with. It needs to not sit in the water.
  • It's important to let the squash stand for 10 minutes before cutting into it.
  • For long strands, cut the squash crosswise, remove the seeds, and then shred. For shorter strands, cut lengthwise, remove the seeds, and shred.
