How To Know If Your Spaghetti Squash Is Bad

You can know if your spaghetti squash is bad by checking its skin, stem, and overall feel before you even cut into it.
 
If you’re wondering how to tell if your spaghetti squash has gone bad, the answer usually shows up in a few obvious ways once you know what to look for.
 
A bad spaghetti squash will typically have soft spots, mold, or a mushy texture that’s hard to miss.
 
In this post, we’ll walk through how to know if your spaghetti squash is bad, what signs mean it’s still good, and how to store it so it lasts longer.
 
Let’s dive in.
 

How to Know If Your Spaghetti Squash Is Bad

Knowing if your spaghetti squash is bad comes down to a handful of clear signs that show up on the outside first.
 
Here’s what to look for:
 

1. Soft or Mushy Spots

A fresh spaghetti squash feels firm and hard all over, almost like a rock.
 
If you press on it and it gives way or feels squishy, that’s one of the biggest signs your spaghetti squash is bad.
 
Soft spots usually mean the flesh inside is breaking down, and that’s not something you want to cook with.
 

2. Mold or Dark Patches

Mold is a dead giveaway that your spaghetti squash has gone bad.
 
Look for fuzzy white, green, or black patches, especially around the stem or any cuts.
 
Dark, sunken spots on the skin are another red flag that your spaghetti squash is past its prime.
 

3. A Slimy or Sticky Surface

A good spaghetti squash has a dry, matte skin.
 
If it feels slimy or sticky to the touch, that’s a strong sign your spaghetti squash is bad and should be tossed.
 

Other Signs Your Spaghetti Squash Has Gone Bad

Sometimes the outside looks fine, but your spaghetti squash is still bad on the inside.
 
Here are a few more ways to tell:
 

1. A Sour or Musty Smell

A healthy spaghetti squash barely smells like anything.
 
If yours has a sour, musty, or fermented smell, your spaghetti squash is bad.
 

2. A Hollow or Unusually Light Feel

Pick up your spaghetti squash and compare its weight to its size.
 
A good one feels heavy for its size, while a bad spaghetti squash feels light and hollow because the inside has dried out or rotted.
 

3. Discolored or Stringy Flesh

Once you cut it open, the flesh should be a bright, even yellow.
 
If you see brown, gray, or mushy strands, your spaghetti squash is bad and shouldn’t be eaten.
 

How Long Does Spaghetti Squash Last?

Knowing how long spaghetti squash lasts helps you figure out if yours is bad or just old.
 

1. Whole Spaghetti Squash

A whole spaghetti squash stored in a cool, dark spot can last one to three months.
 
If it’s been sitting around longer than that, check it closely, because your spaghetti squash may be bad by then.
 

2. Cut Spaghetti Squash

Once you cut your spaghetti squash, it lasts about five to seven days in the fridge.
 
After that, the chances your spaghetti squash is bad go up quickly.
 

3. Cooked Spaghetti Squash

Cooked spaghetti squash keeps for three to five days in an airtight container.
 
If it smells off or looks watery and slimy, your spaghetti squash is bad.
 

What to Do If Your Spaghetti Squash Is Bad

If your spaghetti squash is bad, don’t try to salvage it by cutting away the soft parts.
 
Mold and rot can spread deeper than you can see, so it’s safer to just throw it out.
 
To keep your next spaghetti squash from going bad, store it whole in a cool, dry place and keep cut pieces in the fridge.
 

So, How Do You Know If Your Spaghetti Squash Is Bad?

You know your spaghetti squash is bad when it feels soft, shows mold, smells sour, or has slimy, discolored flesh.
 
A good spaghetti squash stays firm, dry, and heavy, with bright yellow flesh inside.
 
Check your spaghetti squash before cooking, and you’ll never ruin a meal with a spoiled one.
 
When in doubt, toss it out, because a bad spaghetti squash isn’t worth the risk.
