– Little prep. It takes about 2 minutes of active time to set up– 23 minutes of total cook time. About 5 minutes to pressure, 8 minutes under pressure, and 10 minutes of NPR– Safer. You do not have to cut it! This to me is the biggest advantage.
Using the tip of a sharp knife, pierce the squash in several places. You are doing this to allow the heat to penetrate, and to keep the squash from exploding in your pressure cooker.
Close the lid and allow the pressure cooker on HIGH PRESSURE for 8 minutes. Yes I know that doesn't sound like enough time, given that you could be baking spaghetti squash for up to an hour. But this works unless your squash is super ginormous.
You will need to remove the seeds from the squash now. This can be a messy job. I find that using a grapefruit spoon really helps with this process so that you can just scoop them out.
