How to Choose and Store Squash

The squash should:

  • Be firm, and free of cracks or soft spots
  • Feel heavy compared to its size
  • Firm, rounded stem
  • Store the whole squash in a cool, dry place for up to three months
  • Refrigerated for up to two weeks
  • Tightly wrapped in plastic wrap if raw and cut up in pieces in refrigerator

Prep the raw squash

Cut the stem off the top of the squash, and the very bottom of the squash. The squash can be difficult to cut so be sure to choose a large chef’s knife. Cut the spaghetti squash in half lengthwise. This can be difficult, but I generally start in the middle to cut down one side. I’ll make a second cut on the same line to do the other half.

You can also cut the squash in half width-wise. Another option would be to leave whole, and you would have to cut at least a half dozen slits in the squash to release pressure while cooking.

Scoop out the seeds and pulp from each half of the squash. I like to cut my squash in sections to cook then clean out the pieces.

Cooking the spaghetti squash

Place rack in the bottom of your Instant Pot. Pour in one cup of water. I use a 6-quart so if using a larger model be sure to put in the required minimum amount of water required for your model. Place your squash in the pressure cooker.

If you halved or cut your squash into pieces then you should cook on high pressure for 6 minutes. Or, if you would like it softer then cook on high pressure for 8 minutes.

If you left your squash whole with about a dozen slits in it then cook on high pressure for 15 minutes.

For either of the above, once the cooking time is complete then follow with a quick release.

Once the cooking is complete scrape out the flesh, and serve immediately. It can be stored for up to one week in an airtight container. I love to add a little butter, olive oil, Parmesan or Feta cheese, and some fresh cracked pepper to eat for a quick lunch. This is also a great low-carb substitute for pasta for spaghetti dinner.
