You can tell if a butternut squash is ripe by checking its color, skin, and sound.
A ripe butternut squash will have a deep, even tan color with no traces of green.
If you’ve been wondering how to tell if a butternut squash is ripe, the good news is that it’s pretty easy once you know what to look for.
In this post, we’ll walk through the signs that tell you a butternut squash is ripe, plus a few simple tests you can do right in the store or your kitchen.
Let’s get into it.
How Can You Tell If a Butternut Squash Is Ripe?
The best way to tell if a butternut squash is ripe is to use your senses, because a ripe squash gives you plenty of clues.
Here are the main signs to look for:
1. The Color Is Deep and Even
A ripe butternut squash has a rich, uniform beige or tan color.
If you can still see green stripes or patches, that squash isn’t fully ripe yet.
Green means it was picked too early, and the flavor won’t be as sweet.
So when you’re checking how to tell if a butternut squash is ripe, start with the color first.
2. The Skin Is Hard and Matte
Press your fingernail gently into the skin of the squash.
If it’s ripe, your nail won’t leave a dent.
A ripe butternut squash has a tough, hard skin that feels almost like wood.
The skin should also look matte, not shiny.
A glossy surface usually means the squash is still young and not ready yet.
3. The Stem Is Dry and Brown
Look at the stem attached to the top of the squash.
On a ripe butternut squash, the stem is dry, brown, and slightly shriveled.
If the stem is still green or moist, the squash was harvested too soon.
This is one of the easiest ways to tell if a butternut squash is ripe when you’re at the market.
4. It Feels Heavy for Its Size
Pick up the squash and compare it to others nearby.
A ripe butternut squash feels heavy for its size because it’s full of moisture and dense flesh.
If it feels light or hollow, that’s a sign it’s either underripe or drying out inside.
5. It Sounds Hollow When Tapped
Give the squash a gentle tap with your knuckles.
A ripe butternut squash makes a hollow, dull thud sound.
If it sounds solid, the squash may need more time to ripen.
This trick works well alongside the other tests when you’re figuring out how to tell if a butternut squash is ripe.
Can You Ripen a Butternut Squash After Picking It?
Yes, you can ripen a butternut squash after picking it, but only if it was already close to ripe.
If you brought home a squash that’s still a bit green, don’t panic.
Here’s what you can do:
1. Leave It at Room Temperature
Place the butternut squash on your counter or in a cool, dry spot.
Over one to two weeks, it may continue to ripen slightly and deepen in color.
2. Skip the Fridge for Now
Cold temperatures stop the ripening process.
So keep underripe squash out of the refrigerator until it’s fully mature.
Once it’s ripe, though, the fridge is fine for storage.
3. Give It Time, Not Heat
Don’t put your squash in direct sunlight or near a heater.
That can cause it to rot instead of ripen.
A mild room temperature is all it needs.
What Happens If You Cook an Unripe Butternut Squash?
If you cook an unripe butternut squash, it will still be edible, but the texture and flavor won’t be great.
An unripe squash tends to be bland, less sweet, and sometimes stringy.
You can still roast or puree it, but you may need extra seasoning to make up for the lack of natural sweetness.
That said, knowing how to tell if a butternut squash is ripe saves you from this disappointment in the first place.
A ripe one will roast up sweet, creamy, and tender every single time.
So, How Can You Tell If a Butternut Squash Is Ripe?
You can tell if a butternut squash is ripe by checking for a deep tan color, hard matte skin, a dry brown stem, a heavy feel, and a hollow sound when tapped.
Use all of these signs together for the most accurate read.
And if your squash is only slightly underripe, a little time on the counter can help it finish up.
Now you know exactly how to tell if a butternut squash is ripe, so go pick the perfect one for your next soup or roast.
