Place a trivet or steam basket in the Instant Pot.
Cut SPAGHETTI SQUASH in half and scoop out the seeds.
Arrange squash on the trivet, leaving room for the lid to close properly.
Add WATER to the Instant Pot. Increase amount to 2 cups if using an 8 or 10 quart cooker.
Secure the lid, turn pressure release valve to "Sealing", and select 'Manual' or 'Pressure Cook' for 6 minutes on HIGH pressure.
When the pressure cook cycle ends, allow the pot to sit undisturbed for a 10-minute natural pressure release (NPR).
Use any utensil to flip the pressure release valve to "Venting" and release any remaining steam.
Open the lid and test the squash texture with a fork.
Note: For softer noodles, close the lid, set valve to "venting", and let residual heat soften them.
Transfer squash halves out of the Instant Pot and drain off any collected moisture.
Use a fork to gently separate the squash noodles from the shell. Work from the inside towards the shell to help maintain the noodle structure. Transfer noodles to a baking sheet and spread out to cool.
To store, allow to cool completely and refrigerate in an airtight container up to 5 days.

fitting squash in the pressure cooker - Every squash varies in size and shape but, for reference, I find the average 3-ish lb. squash halved fits perfect in the 6 quart Instant Pot. See blog post notes above about pressure cooking it whole.
If you don't have a trivet or steam basket, you can create an aluminum foil ring or set the squash on an inverted cake pan to prevent it from sitting in the water.
You are welcome to season the squash before pressure cooking it, but I prefer to leave it plain because it's more versatile to use in various recipes.
