  • 1 2-3lb spaghetti squash
  • 1 cup water


  1. Cut the spaghetti squash in half length wise. Scoop out the seeds and soft flesh with a large spoon.

  2. Place the 1 cup water along with the Instant Pot trivet insert or steamer basket. Place the spaghetti squash side by side, face up in the Instant Pot.

  3. Close the lid and make sure the sealing valve is set to sealing. Pressure cook on high pressure for 7 minutes.

  4. When the timer goes off, manually release the pressure. When the float valve pin drops, remove the lid and let the spaghetti squash cool for a couple of minutes before removing.

Recipe Notes

It will take the Instant Pot approximately 10 minutes to come to pressure and 3 minutes to release pressure. With the added cook time of 7 minutes, the total cook time (closed lid time) is 20 minutes.
