Instant Pot Spaghetti Squash

I have had this spaghetti squash sitting on my country since winter, so it is safe to say that spaghetti squash stored in a cool dry place can last for up to 3 months, once it doesn't have any soft spots.

I was amazed how easy it was to be prepared in my Instant Pot, taking only 10 minutes once the pressure cooker comes to pressure.  If you want to prepare your spaghetti squash the traditional way baking or steaming it in an oven, it takes about 50 minutes, check out my Southwestern Stuffed Spaghetti Squash Recipe

It is amazing how this simple squash has these strands like spaghetti when cooked. The delicate flavor of the spaghetti squash also known as noodle squash and vegetable marrow is the perfect base for adding your favorite sauces.

How To Cook Spaghetti Squash In Instant Pot?

To cook spaghetti squash in an Instant Pot, I have a 6 quart Instant Pot so make sure that your squash isn't too large to fit in your pressure cooker.  3-pound spaghetti squash was able to fit perfectly in the insert of my Instant Pot.

  1. Wash and dry your spaghetti squash, using a sharp knife, cut your squash lengthwise in half. Due to the size of my squash, that was the best way to cut my squash. If your spaghetti squash is around 2 pounds or less you can cut yours horizontally. 
  2. Using a spoon, scoop out the seeds in the middle of your spaghetti squash, you can save them to plant if you have a garden. If not discard.
  3. Put a steam basket or trivet at the bottom of the Instant Pot, add 1 cup of water. Place the two halves of the spaghetti squash side by side on top of the trivet or steam basket. 
  4. Secure the lid on the Instant Pot, turn the Pressure Release knob to the Sealing position. Press the Pressure Cook/Manual setting and set the cooking time for 10 minutes. (It takes about 10 minutes for the Instant Pot to come to pressure).
  5. Do a quick release after the timer beeps by turning the kob to Venting. I usually cover the steam release valve with a damp kitchen towel to stop the steam from ruining my ceiling. This method is great for stopping the cooking process. Once the Floating Valve (metal pin) drops you can open the lid. 
  6. Carefully remove the spaghetti squash halves, using an oven mitt to transfer onto a cutting board. Using a fork, separate the flesh of the squash into strands. You have the option of adding your sauce or dressing in the shell of the squash or transfer the strands to a serving bowl or plate and discarding the skin. 
  7. Cook spaghetti squash should last 3-5 days in a covered container in the refrigerator. I served mine as a  vegan garlic parmesan spaghetti squash.
