Updated on May 17, 2023
If you’re looking for a low-carb pasta alternative, spaghetti squash is for you. This simple step-by-step guide will show you how to make Instant Pot spaghetti squash in under 10 minutes.
Spaghetti squash is harvested in fall but can last for months when stored in a cool place, so it’s typically available from early fall through winter. Once it’s cooked, serve it as is, with pasta sauce, drizzled with pesto or baked in a casserole. The options are endless!
Cooking spaghetti squash in a pressure cooker only takes about 8 minutes, plus the time it takes to come to pressure. The end result is fluffy, crunchy noodle-like strands that have a mild, slightly sweet taste.

Ingredients
- Spaghetti squash
- Olive oil
- Salt
- Pepper
Directions
Step 1: Grab your pressure cooker
Place the wire rack or trivet inside your Instant Pot and add 1 cup of water.
Step 2: Prepare the spaghetti squash
Using a sharp knife, carefully cut the spaghetti squash in half. With a spoon, scoop out the seeds and discard. Alternatively, set aside and roast squash seeds for a healthy snack. Brush with a drizzle of olive oil and sprinkle with salt and pepper.
Step 3: Cook spaghetti squash in the Instant Pot
Transfer squash to the Instant Pot, close the lid and make sure the vent is turned to Sealed. Manually cook on high pressure for 8 minutes. Once the squash is done cooking, manually quick release the pressure by toggling the valve to Vent. Watch out for the spray of the steam!

How to Serve Instant Pot Spaghetti Squash

Tips for Making Instant Pot Spaghetti Squash
How long do you cook spaghetti squash in an Instant Pot?
Instant Pot spaghetti squash cooks in just 8 minutes, plus the time it takes to come to pressure, which is usually an additional 10 minutes. From start to finish, cooking spaghetti squash in a pressure cooker takes just under 20 minutes.
Can you cook a whole spaghetti squash in the Instant Pot?
Yes! Be sure to pierce the spaghetti squash with a knife or fork to vent, then follow the standard instructions by placing it on the trivet with 1 cup of water and cooking on high pressure for 15 minutes. Allow the pressure to naturally release for 10 minutes before manually turning the pressure release valve.
What should I do if my squash is undercooked?
If you slice into your squash and realize it’s not fully cooked, continue to cut the squash open and remove the seeds. Place each half, one at a time, in a microwave-safe bowl along with a touch of water. Microwave until fork-tender, about an additional 2-3 minutes for each half.
What happens if I overcook spaghetti squash?
Overcooked squash has a spongy, mushy texture, rather than the crisp-tender bite of a properly cooked squash.
If you overcook the spaghetti squash, place the squash halves cut-side down on a clean kitchen towel or paper towel. Let sit for at least 5 minutes to help remove the excess liquid. This trick will help improve the texture and taste!
Can I store leftover spaghetti squash?
Absolutely. Store leftovers in an airtight container in the fridge for up to 5 days or in the freezer for up to 3 months.
