Carefully cut 1 spaghetti squash in half lengthwise.
Use a spoon to scoop out and discard the seeds and stringy center.
Place both squash halves in the electric pressure cooker, cut-side up, stacking if necessary.
Pour 1 cup of water into the bottom of the pressure cooker.
Secure the lid and set the valve to the Sealing position.
Select Manual/Pressure Cook (High Pressure) and set the timer for 5 minutes.
When the cooking cycle is complete, perform a quick release.
Carefully remove the squash from the pressure cooker.
Using a fork, scrape the flesh lengthwise to create spaghetti-like strands.
Season with ½ teaspoon salt and ½ teaspoon black pepper,
Serve immediately and enjoy!
Notes
A small to medium spaghetti squash (about 2-3 lbs) fits best in a 6-quart Instant Pot. If yours is larger, or your pot is smaller, cook the halves one pair at a time or use an 8-quart pot.
Leftover squash keeps in the fridge for up to 4 days, or in the freezer for up to 3 months.
