Let’s dive in.
 

Why Cook Whole Butternut Squash in the Instant Pot

Cooking whole butternut squash in an Instant Pot solves the biggest problem with this veggie: cutting it raw.
 
Here’s why this method works so well.
 

1. No Dangerous Chopping Required

Raw butternut squash is famously tough, and trying to halve it with a chef’s knife is a common kitchen injury waiting to happen.
 
When you cook whole butternut squash in the Instant Pot, the pressure does all the hard work for you.
 
Once it’s done, the skin is soft enough to slice through with a butter knife.
 

2. Hands-Off Cooking Time

Roasting a whole butternut squash in the oven can take over an hour, and you have to babysit it.
 
An Instant Pot cooks whole butternut squash in about 45 minutes with zero monitoring.
 
You just add water, set the timer, and walk away.
 

3. Naturally Sweet, Silky Flesh

Pressure cooking traps steam inside the pot, so the squash steams in its own moisture.
 
That’s why whole butternut squash cooked in an Instant Pot comes out creamier and sweeter than boiled or microwaved versions.
 
The natural sugars concentrate instead of leaching into the water.
 

4. Easy to Scoop and Use

After cooking whole butternut squash in the Instant Pot, the flesh scoops out with a spoon.
 
You can mash it, puree it, or cube it for soups, pastas, and baby food.
 

How to Cook Whole Butternut Squash in an Instant Pot Step by Step

Learning how to cook whole butternut squash in an Instant Pot takes just a few minutes of prep.
 
Here’s the process.
 

1. Prep the Squash and the Pot

Rinse the whole butternut squash and pat it dry.
 
If it’s too tall for your Instant Pot, you can cook whole butternut squash by trimming just the stem so the lid fits, or cut it in half crosswise if needed.
 
Prick the skin a few times with a fork so steam can escape.
 
Pour one cup of water into the inner pot and place the trivet inside.
 

2. Position and Pressure Cook

Set the whole butternut squash on the trivet, then lock the lid and seal the valve.
 
Cook whole butternut squash on High Pressure for 25 minutes for a small squash, or up to 40 minutes for a large one.
 
A good rule is about 15 minutes per pound.
 

3. Natural Release and Check for Doneness

When the timer beeps, let the pressure release naturally for 10 minutes, then quick-release the rest.
 
To test if your whole butternut squash is done, insert a fork near the stem.
 
If it slides in with no resistance, the squash is ready.
 
If it feels firm, cook whole butternut squash for another 5 minutes.
 

4. Cool, Peel, and Serve

Let the squash rest until it’s cool enough to handle.
 
The skin will peel away easily, or you can slice the squash open, scoop out the seeds, and mash the flesh.
 
Cooking whole butternut squash in the Instant Pot gives you a blank canvas for soups, casseroles, or a simple side with butter and cinnamon.
 

Tips for Perfect Instant Pot Whole Butternut Squash

A few small tweaks make cooking whole butternut squash in the Instant Pot even easier.
 

1. Size Matters

Smaller squash cook faster, so check yours before setting the timer.
 
If you’re cooking whole butternut squash that’s especially large, add 5 to 10 extra minutes.
 

2. Don’t Skip the Trivet

The trivet keeps the squash out of the water so it steams instead of boils.
 
That’s the secret to why whole butternut squash in the Instant Pot tastes roasted rather than waterlogged.
 

3. Use the Right Amount of Water

One cup is enough for a 6-quart Instant Pot.
 
Too little water can trigger a burn notice, and too much can dilute the flavor.
 

4. Store Leftovers Properly

Once you’ve cooked whole butternut squash, scoop the flesh into an airtight container.
 
It keeps in the fridge for up to five days or in the freezer for three months.
