Cut the spaghetti squash in half. If you want longer stands, cut it in half lengthwise. For shorter strands cut it across the width.
Scoop out the seeds and discard them.
Place the trivet in your Instant pot along with 1 cup of water.
Place the spaghetti squash on top of the trivet and close the lid, setting the vent to “seal.”
Set the Instant Pot to high for 7 minutes.
Press start.
After the 7 minutes, turn the knob to vent. Once all the steam has released, use tongs or silicone mitts to remove the spaghetti squash from the Instant Pot.
Place it on a cutting board or plate.
Use a fork to pull the strands away from the outside shell of the squash.
