You can pressure cook butternut squash to get perfectly tender, velvety results in a fraction of the time it takes to roast it in the oven.
If you’ve ever wondered how to pressure cook butternut squash without ending up with a mushy mess, you’re in the right place.
When you pressure cook butternut squash, the high-pressure steam penetrates the dense flesh quickly, breaking down fibers and turning it soft and scoopable.
This method is a game-changer for soups, purees, baby food, and healthy side dishes.
In this post, we’ll walk through exactly how to pressure cook butternut squash, whether you’re using an Instant Pot or a stovetop pressure cooker.
Let’s get into it.
How to Pressure Cook Butternut Squash: The Basic Method
Learning how to pressure cook butternut squash is simple once you know the steps, and the payoff is huge.
Here’s the core process you’ll follow every time you pressure cook butternut squash.
1. Prep the Squash
First, wash the outside of your butternut squash thoroughly.
You don’t have to peel it before you pressure cook butternut squash, which saves a ton of time and effort.
Just cut off the stem and the very bottom, then slice the squash in half lengthwise.
Scoop out the seeds and stringy pulp with a spoon.
If the squash is too hard to cut, you can microwave it for two to three minutes to soften the skin slightly.
2. Add Water and a Trivet
Pour one cup of water into the bottom of your pressure cooker.
Place a trivet or steamer basket inside so the squash sits above the water rather than boiling in it.
This is the secret to how to pressure cook butternut squash without it turning waterlogged.
3. Arrange the Squash
Place the squash halves cut-side up on the trivet.
If your squash is large, cut it into smaller chunks so it fits comfortably.
You can stack pieces, but try to keep them in a single layer when possible for even cooking.
4. Set the Time and Pressure
Secure the lid and set the valve to sealing.
For an Instant Pot, cook on high pressure for 12 to 15 minutes for a whole halved squash.
If you’ve cubed the squash, reduce the time to 8 to 10 minutes.
Learning how to pressure cook butternut squash is really about timing, so adjust based on the size of your pieces.
5. Natural Release and Check
When the cook time ends, let the pressure release naturally for 10 minutes, then do a quick release for any remaining pressure.
Open the lid and test the squash with a fork.
It should slide in easily with no resistance.
If it’s still firm, lock the lid back on and cook for another 2 to 3 minutes.
Why You Should Pressure Cook Butternut Squash
There are plenty of reasons to pressure cook butternut squash instead of roasting or boiling it.
Once you try this method, you might never go back.
1. It’s Much Faster
Roasting a whole butternut squash can take 45 minutes to an hour.
When you pressure cook butternut squash, you’re looking at 12 to 15 minutes of active cooking time.
That’s a massive time saver on busy weeknights.
2. The Texture Is Consistently Perfect
The controlled steam environment means you get evenly cooked squash every single time.
No dry edges, no undercooked centers.
If you pressure cook butternut squash correctly, the flesh becomes silky and smooth, ideal for mashing or pureeing.
3. It Retains More Nutrients
Boiling leaches water-soluble vitamins into the cooking liquid.
When you pressure cook butternut squash, the squash steams above the water, so it holds onto more of its vitamins and minerals.
That means more nutrition in every bite.
4. Peeling Becomes Optional
The skin of butternut squash softens dramatically during pressure cooking.
In fact, after you pressure cook butternut squash, the skin often peels right off with your fingers or a spoon.
This eliminates one of the most tedious parts of preparing this vegetable.
Tips for the Best Pressure Cooked Butternut Squash
To really nail how to pressure cook butternut squash, keep these tips in mind.
1. Don’t Overcrowd the Cooker
Leave some space around the squash pieces so steam can circulate freely.
If you pressure cook butternut squash in a crowded pot, some pieces will cook unevenly.
2. Use the Right Amount of Water
One cup is usually enough for a 6-quart Instant Pot.
Too little water can cause burning, and too much can make the squash soggy.
Getting this ratio right is key when you pressure cook butternut squash.
3. Season After Cooking
Wait until after you pressure cook butternut squash to add salt, butter, or spices.
Seasonings added before cooking can become concentrated or alter the texture.
A little brown sugar, cinnamon, or maple syrup goes a long way once the squash is tender.
4. Save the Cooking Liquid
The water left in the pot after you pressure cook butternut squash is packed with flavor.
Use it to thin out soups, purees, or even smoothies.
Don’t just pour it down the drain.
So, How to Pressure Cook Butternut Squash?
You can pressure cook butternut squash by prepping it, adding water and a trivet, setting high pressure for 12 to 15 minutes, and letting the pressure release naturally.
It’s faster than roasting, retains more nutrients, and gives you perfectly tender squash every time.
Whether you’re making soup, baby food, or a simple side dish, knowing how to pressure cook butternut squash will save you time and effort in the kitchen.
Give it a try, and you’ll wonder why you ever did it any other way.
