How Long Do You Cook Spaghetti Squash in Instant Pot?

When you cook spaghetti squash in Instant Pot, the timing mainly depends on whether it’s whole or cut.
 
Here’s a simple breakdown so you can nail it every time:
 

1. Whole Spaghetti Squash

A medium whole spaghetti squash (about 2 to 3 pounds) needs 15 to 20 minutes on high pressure.
 
You’ll need to pierce it several times with a fork so steam can escape and it doesn’t burst.
 
Add 1 cup of water to the Instant Pot, place the squash on the trivet, and cook for 15 minutes for a firmer texture or up to 20 minutes for a softer one.
 
Then let the pressure release naturally for about 10 minutes before quick releasing the rest.
 

2. Halved Spaghetti Squash

If you cut the squash in half and scoop out the seeds, the cook time drops to 7 to 10 minutes on high pressure.
 
This is the faster route, and it’s great when you want those long, perfect strands.
 
Place the halves cut-side up on the trivet, add 1 cup of water, and set the Instant Pot to high pressure for 7 minutes.
 
Do a quick release after 5 minutes of natural release, and you’re done.
 

3. Spaghetti Squash Pieces or Cubes

Some people cut the squash into rings or cubes to cook even faster.
 
For cubes or rings, cook for 5 to 7 minutes on high pressure.
 
This method works well if you’re in a hurry or want to add the squash directly into soups or casseroles.
 
Just remember that smaller pieces cook quicker, so keep an eye on them.
 

How to Prepare Spaghetti Squash for the Instant Pot

Preparing your spaghetti squash properly is just as important as the cook time.
 
Here’s how to do it step by step:
 

1. Wash and Pierce (If Whole)

Rinse the squash under running water to remove any dirt.
 
If you’re cooking it whole, grab a fork and pierce it all over, about 10 to 15 times.
 
This prevents the squash from exploding under pressure and lets steam escape.
 

2. Cut and Scoop (If Halved)

Use a sharp knife to cut the squash in half lengthwise.
 
Scoop out the seeds and stringy bits with a spoon, just like you would with a pumpkin.
 
You can leave the skin on; it’ll peel away easily after cooking.
 

3. Add Water and Trivet

Pour 1 cup of water into the Instant Pot inner pot.
 
Place the trivet or a steamer basket inside so the squash doesn’t sit directly in the water.
 
This keeps the squash from getting soggy and helps it cook evenly.
 

4. Layer the Squash

Place the whole squash or halves on the trivet.
 
If you have two halves, you can stack them, but try not to overcrowd the pot.
 
For cubes or rings, you can pile them loosely.
 

Tips for Perfect Instant Pot Spaghetti Squash

Getting the timing right is key, but these extra tips will make your spaghetti squash turn out amazing:
 

1. Don’t Skip the Natural Release

After cooking, let the pressure release naturally for at least 5 to 10 minutes.
 
This helps the squash finish cooking gently without turning to mush.
 
If you quick release too soon, the texture can suffer.
 

2. Test for Doneness

A perfectly cooked spaghetti squash should be tender when pierced with a fork.
 
The strands should separate easily when you scrape the inside with a fork.
 
If it’s still firm, cook for 2 to 3 more minutes under high pressure.
 

3. Shred While Warm

Once it’s cool enough to handle, use a fork to scrape the flesh into strands.
 
Do this while the squash is still warm because it shreds much easier than when cold.
 

4. Season After Cooking

Spaghetti squash has a mild flavor, so season it after cooking.
 
A little olive oil, salt, pepper, and garlic powder goes a long way.
 
You can also toss it with your favorite pasta sauce for a low-carb meal.
 

So, How Long Do You Cook Spaghetti Squash in Instant Pot?
