If you’ve been wondering how to cook an acorn squash in an Instant Pot without turning it into a mushy mess, you’re in the right place.

Let’s get cooking.
 

How to Cook an Acorn Squash in an Instant Pot

Cooking an acorn squash in an Instant Pot comes down to a few simple steps, and once you learn them, you’ll never go back to the oven.
 
Here’s what makes it work so well.
 

1. Prep the Squash the Right Way

Before you cook an acorn squash in an Instant Pot, give it a good rinse and scrub the skin since you may end up eating some of it.
 
Use a sharp knife to slice off the stem and the little pointed tip at the bottom so the squash sits flat.
 
If you’re cooking it whole, that’s all the prep you need.
 
If you want it halved, cut it right down the middle and scoop out the seeds with a spoon.
 

2. Add Water and a Trivet

Pour one cup of water into the inner pot of your Instant Pot.
 
This water is what creates the steam that cooks the acorn squash.
 
Place a trivet or steamer basket inside so the squash sits above the water instead of boiling in it.
 
This keeps the texture nice and prevents it from getting waterlogged.
 

3. Set the Time and Pressure

For a whole acorn squash, pressure cook on high for about 20 to 25 minutes, depending on size.
 
For halves, 10 to 15 minutes is usually plenty.
 
When you cook an acorn squash in an Instant Pot, you want to use the manual or pressure cook setting rather than a preset.
 
Once the timer goes off, let the pressure release naturally for about 10 minutes, then do a quick release for the rest.
 

4. Check for Doneness

A fork or knife should slide in easily with no resistance when the squash is done.
 
If it still feels firm, seal the lid and cook it for a few more minutes.
 
The beauty of learning how to cook an acorn squash in an Instant Pot is that you can always add a little more time without ruining it.
 

Whole vs Halved: Which Way Should You Cook Acorn Squash in an Instant Pot?

Both methods work great when you cook acorn squash in an Instant Pot, and the one you choose depends on what you’re making.
 

1. Cooking It Whole

Cooking the acorn squash whole is hands down the easiest approach.
 
There’s no cutting through that tough raw skin, no scooping, and no fuss.
 
Once it’s done, the squash is soft enough that you can slice it open and scoop out the seeds in seconds.
 
This method is perfect when you plan to mash, puree, or stuff the squash after cooking.
 

2. Cooking It Halved

If you want to serve the acorn squash in neat halves, cut it before cooking.
 
Halves cook faster and give you a nice presentation for stuffing with rice, sausage, or veggies.
 
Just season the cut side, place it on the trivet, and pressure cook.
 
Either way, you’ll end up with tender squash that’s ready to eat.
 

Tips for the Best Instant Pot Acorn Squash

A few small tweaks make a big difference when you cook an acorn squash in an Instant Pot.
 

1. Don’t Skip the Natural Release

Letting the pressure come down naturally for about 10 minutes helps the squash finish cooking gently.
 
Skip this step and you risk a tougher texture.
 

2. Season After Cooking

Once your acorn squash is cooked, that’s the time to add butter, brown sugar, maple syrup, cinnamon, or a pinch of salt.
 
Seasoning after keeps the flavors bright and lets you taste as you go.
 

3. Size Matters

A small acorn squash might be done in 15 minutes, while a large one could take closer to 25 or 30.
 
Always check with a fork before assuming it’s ready.
 

4. Save the Seeds

Don’t toss those seeds if you halve the squash.
 
Rinse them, toss with oil and salt, and roast them for a crunchy snack.
 

So, How Do You Cook an Acorn Squash in an Instant Pot?

You cook an acorn squash in an Instant Pot by adding water, placing the squash on a trivet, and pressure cooking it for 15 to 25 minutes until tender.
 
It’s faster than the oven, requires almost no prep, and gives you perfectly soft, sweet squash every time.
 
Whether you cook it whole or halved, the Instant Pot takes the guesswork out of this cozy fall favorite.
 
Give it a try, and you’ll wonder why you ever waited on the oven.
