How to Cook Spaghetti Squash in an Instant Pot

For the full recipe, see the recipe card at the end of the post.

First, start by gathering your ingredients.

Add the broth to the Instant Pot and top with the trivet. Cut your spaghetti squash in half and remove the seeds.

Be careful, and make sure you use a very sharp knife. It is easy to cut yourself here.

Broth is in an Instant Pot and the spaghetti squash is cut in half.

Place the cut spaghetti squash in the Instant Pot on top of the trivet. Close the lid. Don't forget to make sure the vent is turned to seal.

Set the pressure to manual high and the timer to 7 minutes.

When the timer goes off, press the release valve to release all of the pressure. Using the Instant Release Method prevents overcooking.

I recommend using an oven mitt or kitchen towel to do this.
