You can cook acorn squash in an Instant Pot by pressure cooking it whole or cut in half, and it comes out perfectly tender every single time.
If you’ve been wondering how to cook acorn squash in an Instant Pot without the hassle of wrestling with a rock-hard squash on a cutting board, you’re in the right place.
The Instant Pot makes cooking acorn squash incredibly easy because the steam and pressure do all the heavy lifting for you.
You don’t need to struggle with a sharp knife, and you don’t even need to scoop out the seeds before cooking if you don’t want to.
In this post, we’ll go over exactly how to cook acorn squash in an Instant Pot, plus a few tasty variations you can try.
Let’s dive in.
How Do You Cook Acorn Squash in an Instant Pot?
Cooking acorn squash in an Instant Pot is as simple as adding water, placing the squash on a trivet, and setting the timer.
Here’s why this method works so well:
1. It’s Faster Than the Oven
When you cook acorn squash in an Instant Pot, you’re looking at about 15 to 25 minutes of pressure cooking time depending on the size.
Compare that to roasting, which can take 45 minutes to an hour, and you can see why so many people love cooking acorn squash this way.
The pressure cooking method locks in moisture too, so the flesh stays creamy instead of drying out.
2. You Can Cook It Whole
One of the best things about how to cook acorn squash in an Instant Pot is that you can toss the whole squash in without cutting it.
Just pierce it a few times with a fork so steam can escape, add a cup of water to the pot, and let the Instant Pot do its thing.
Once it’s done, the skin softens enough that you can slice it open with almost no effort at all.
3. It Steams Instead of Roasts
The Instant Pot cooks acorn squash using steam and pressure, which gives you a soft, scoopable texture.
You won’t get the caramelized edges you’d get from roasting, but you will get a perfectly cooked squash that’s ready to mash, stuff, or turn into soup.
If you want a little browning afterward, you can always pop it under the broiler for a few minutes.
4. Cleanup Is a Breeze
Since everything happens in one pot, cooking acorn squash in an Instant Pot means way less mess.
No baking sheets to scrub, no sticky oven racks, and no squash seeds scattered all over your counter.
That alone makes this method worth trying.
Step-By-Step Guide to Cooking Acorn Squash in an Instant Pot
Ready to cook acorn squash in your Instant Pot?
Here’s the process:
1. Prep the Squash
Rinse your acorn squash under running water and pat it dry.
If you’re cooking it whole, pierce it several times with a fork or paring knife.
If you prefer to cut it, slice it in half, scoop out the seeds, and season the flesh with salt and pepper.
2. Add Water and a Trivet
Pour one cup of water into the Instant Pot and place the trivet or steamer basket inside.
The trivet keeps the squash out of the water so it steams rather than boils.
3. Set the Timer
For a whole acorn squash, set your Instant Pot to high pressure for 20 to 25 minutes.
For halves, 12 to 15 minutes on high pressure is usually enough.
4. Do a Natural Release
When the timer goes off, let the pressure release naturally for about 10 minutes before flipping the valve.
This keeps the squash from falling apart and helps it finish cooking gently.
5. Serve It Up
Once it’s cool enough to handle, scoop out the flesh or slice it into wedges.
You can mash it with butter, brown sugar, or maple syrup, or stuff it with rice, sausage, or veggies.
Tips for the Best Instant Pot Acorn Squash
Keep these pointers in mind when you cook acorn squash in an Instant Pot:
1. Choose a Squash That Fits
Make sure your acorn squash fits comfortably inside your Instant Pot.
If it’s too big, cut it in half or quarters so the lid can seal properly.
2. Don’t Skip the Trivet
The trivet is what makes this steamed squash turn out so well.
Without it, the squash sits in water and gets soggy.
3. Season After Cooking
If you’re cooking acorn squash whole, season it after it’s done and sliced open.
Salt, pepper, cinnamon, and a little butter go a long way here.
4. Use the Cooking Liquid
The water left in the pot picks up squash flavor, so don’t dump it.
Use it as a base for soup or to thin out mashed squash.
So, How Do You Cook Acorn Squash in an Instant Pot?
You cook acorn squash in an Instant Pot by adding water and a trivet, placing the squash inside, and pressure cooking it for 12 to 25 minutes depending on whether it’s halved or whole.
It’s quick, it’s hands-off, and it gives you tender squash every time with almost no cleanup.
Whether you’re making soup, a side dish, or a stuffed squash dinner, this method saves you time and effort.
Give it a try the next time you want to cook acorn squash in an Instant Pot.
Once you do, you might never go back to the oven again.
