By the end, you’ll know how to cook squash in a pressure cooker with confidence, whether you’re using an Instant Pot, a stovetop model, or another electric pressure cooker brand.
Let’s dive in.
Why Cooking Squash in a Pressure Cooker Works So Well
You can cook squash in a pressure cooker because the sealed, high-pressure environment traps steam and cooks the squash quickly and evenly.
The pressure cooker essentially steams the squash from the inside out, so you get soft, scoopable flesh without drying it out.
Here are a few reasons this method really shines.
1. It’s Fast
When you cook squash in a pressure cooker, you cut the cooking time dramatically compared to roasting or boiling.
A whole butternut squash that might take 45 minutes in the oven can be done in about 15 to 20 minutes under pressure, plus the time it takes to come up to pressure.
That speed makes it practical for weeknight meals when you don’t want to wait around.
2. It Keeps the Squash Moist
Because the pressure cooker uses steam, the squash stays moist and tender rather than turning dry or stringy.
This is especially helpful for squash varieties that tend to get tough when overcooked.
You’ll notice the difference the moment you scoop out the flesh.
3. It’s Hands-Off
Once you lock the lid, you can walk away and do something else while the pressure cooker does its job.
No stirring, no checking, no babysitting.
It’s one of the most relaxed ways to cook squash in a pressure cooker.
How to Cook Squash in a Pressure Cooker Step by Step
Learning how to cook squash in a pressure cooker comes down to a few simple steps.
Follow these and you’ll get great results with almost any winter squash.
1. Choose and Prep Your Squash
Start with a firm squash that feels heavy for its size.
Wash the outside well, since you’ll be cutting through the skin.
You can cook squash in a pressure cooker whole, halved, or cut into chunks, depending on the variety and your recipe.
For butternut and acorn squash, cutting them in half and scooping out the seeds works best.
For spaghetti squash, halve it lengthwise and remove the seeds too.
2. Add Water to the Pressure Cooker
Pour about one cup of water into the bottom of the pressure cooker.
This creates the steam that cooks the squash.
If your cooker came with a trivet or steamer rack, place it in the pot so the squash sits above the water.
That keeps the squash from getting waterlogged while it cooks.
3. Place the Squash Inside
Set the squash on the trivet, cut side up if you halved it.
If you’re cooking several pieces, arrange them so they’re not tightly packed.
You want steam to circulate freely around each piece so everything cooks evenly.
4. Lock the Lid and Set the Time
Secure the lid and set the valve to sealing.
For cubed squash, cook on high pressure for about 4 to 6 minutes.
For halved squash, cook for 7 to 10 minutes.
For a whole small squash, plan on 15 to 20 minutes.
These times are guidelines, and thicker squash will need the longer end of the range.
5. Do a Quick Release
When the timer goes off, carefully do a quick release to stop the cooking.
Squash can go from perfectly tender to mushy fast, so releasing pressure right away helps you stay in control.
Once the pin drops, open the lid away from your face to avoid the hot steam.
6. Check for Doneness
Pierce the squash with a fork or knife.
It should slide in easily with little resistance.
If it’s still firm, lock the lid back on and cook for another 2 to 3 minutes.
Then scoop, mash, or cube the squash depending on what you’re making.
Tips for Perfect Pressure Cooker Squash
A few small habits make a big difference when you cook squash in a pressure cooker.
1. Don’t Overcook It
Squash cooks quickly under pressure, so start with the shorter time and add more if needed.
Overcooked squash turns watery and loses its shape.
2. Season After Cooking
Add butter, salt, pepper, or maple syrup after the squash is done.
Seasoning before cooking can burn or settle unevenly in the steamy environment.
3. Save the Seeds
If you scoop out seeds, rinse and roast them later for a crunchy snack.
It’s a nice bonus when you cook squash in a pressure cooker.
4. Use the Right Amount of Water
Too little water can cause scorching, and too much can make the squash soggy.
One cup is usually the sweet spot for most electric pressure cookers.
So, How Do You Cook Squash in a Pressure Cooker?
You cook squash in a pressure cooker by prepping the squash, adding water and a trivet, then cooking under high pressure for a short time and releasing quickly.
It’s fast, simple, and gives you tender squash that’s perfect for soups, casseroles, baby food, or a simple side dish.
Once you get the hang of it, you’ll wonder why you ever waited on the oven.
Give it a try, and you’ll see just how easy it is to cook squash in a pressure cooker whenever the craving hits.
