You can steam cubed butternut squash to tender, sweet perfection in about 15 minutes.
 
Steaming cubed butternut squash is one of the easiest, healthiest ways to cook this earthy, slightly sweet vegetable.

And it preserves more nutrients, especially water-soluble vitamins like vitamin C and B vitamins.
 
Whether you’re making a soup, a baby food puree, or a simple side dish, steamed cubed butternut squash is a great starting point.
 
In this post, I’ll walk you through exactly how to steam cubed butternut squash, plus a few tips to make it foolproof every time.
 
Let’s get to it.
 

How to Steam Cubed Butternut Squash Step by Step

Learning how to steam cubed butternut squash takes just a few simple steps, and once you do it once, you’ll never look back.
 
Here’s how it all comes together.
 

1. Cut the Squash into Even Cubes

First, peel the butternut squash with a sharp vegetable peeler.
 
Then slice off both ends, cut it in half lengthwise, and scoop out the seeds with a spoon.
 
Now cut the squash into cubes about 1 inch thick.
 
The key here is to keep your cubes roughly the same size so they steam evenly.
 
If you’re wondering how to steam cubed butternut squash without any turning to mush, even cubing is the answer.
 

2. Set Up Your Steamer

Fill a pot with about 1 to 2 inches of water, making sure the water doesn’t touch the bottom of your steamer basket.
 
Place the steamer basket inside the pot.
 
If you don’t have a steamer basket, a metal colander that fits inside your pot works just fine.
 
Bring the water to a boil over medium-high heat.
 

3. Steam the Cubed Butternut Squash

Once the water is boiling, carefully add your cubed butternut squash to the steamer basket in a single layer.
 
Don’t pile them up too high or the ones in the middle won’t cook evenly.
 
Cover the pot with a lid and let it steam for about 12 to 15 minutes.
 
How long you steam cubed butternut squash depends on how big your cubes are.
 
Smaller cubes might be done in 10 minutes, while larger ones could take up to 20.
 

4. Check for Doneness

After about 12 minutes, pierce a cube with a fork or a paring knife.
 
If it slides in easily with just a little resistance, your cubed butternut squash is done.
 
You want it tender but not falling apart.
 
If a fork goes in with no resistance at all, you’ve probably overcooked it a bit.
 
That’s not the end of the world, but it will be mushy, so keep an eye on it.
 

5. Serve or Store

Once your steamed cubed butternut squash is done, carefully remove the basket from the pot.
 
Let it cool for a few minutes before serving or using it in a recipe.
 
You can mash it, toss it with butter and herbs, or blend it into a soup.
 
If you’re meal prepping, steamed cubed butternut squash stores beautifully in the fridge for up to 4 days in an airtight container.
 

Why Steaming Cubed Butternut Squash Beats Other Cooking Methods

There are plenty of ways to cook butternut squash, but steaming cubed butternut squash has some real advantages.
 
Here’s why it’s worth the effort.
 

1. It Keeps the Nutrients Locked In

When you boil cubed butternut squash, many of the water-soluble vitamins leach out into the cooking water.
 
Steaming keeps the squash out of the water, so those nutrients stay right where you want them.
 

2. The Texture Stays Perfect

Steaming gives you a consistently tender, creamy texture without the waterlogged sogginess that boiling can cause.
 
The cubes hold their shape while still being soft enough to mash or puree.
 

3. It’s Fast and Hands-Off

Once your cubed butternut squash is in the steamer, you can walk away and do something else.
 
No stirring, no babysitting, no oil splatter.
 
You just set a timer and come back to perfectly cooked squash.
 

Common Mistakes When You Steam Cubed Butternut Squash

Even a simple method like steaming cubed butternut squash can go wrong if you’re not careful.
 
Here are a few pitfalls to avoid.
 

1. Uneven Cubes

If your cubed butternut squash pieces are all different sizes, the small ones will overcook before the big ones are tender.
 
Take the extra minute to cut them evenly.
 

2. Too Much Water in the Pot

If the water level is too high, it can bubble up into the steamer basket and essentially boil your squash.
 
Keep the water below the basket and you’re good.
 

3. Lifting the Lid Too Often

Every time you lift the lid, you let out steam and slow down the cooking process.
 
Resist the urge to peek and trust your timer instead.
 

So, How Do You Steam Cubed Butternut Squash?

You steam cubed butternut squash by cutting it into even 1-inch cubes, placing them in a steamer basket over boiling water, and cooking for 12 to 15 minutes until fork-tender.
 
It’s a simple, healthy cooking method that keeps the squash sweet, vibrant, and full of nutrients.
 
Whether you’re making a cozy soup or just want a quick side dish, now you know exactly how to steam cubed butternut squash perfectly every single time.
