Once cooked, that timeline shrinks dramatically to just 3 to 5 days in the refrigerator.
 
If you’ve been wondering how long before spaghetti squash goes bad, you’re in good company.
 
Plenty of home cooks stash one in the pantry and then completely forget it’s there.
 
This post will walk you through exactly how long spaghetti squash lasts, the signs it’s gone bad, and how to store it so you get the most life out of every single one.
 
Let’s dive in.
 

How Long Before Spaghetti Squash Goes Bad?

So how long before spaghetti squash goes bad?
 
A whole, uncut spaghetti squash stored in optimal conditions can last anywhere from 1 to 2 months, and some varieties can hold up for up to 3 months if kept perfectly.
 
Once you cut it open, the clock starts ticking fast.
 
A cut spaghetti squash lasts about 3 to 4 days in the fridge when wrapped tightly.
 
Cooked spaghetti squash goes bad in about 3 to 5 days, so it won’t stay fresh nearly as long.
 
Frozen cooked spaghetti squash is the exception and can last up to 10 to 12 months in the freezer.
 
The key takeaway is simple: the more you process spaghetti squash, the faster it goes bad.
 

Signs Your Spaghetti Squash Has Gone Bad

Knowing how long before spaghetti squash goes bad is one thing, but recognizing the signs is what really matters.
 
Here’s what to look for:
 

1. Soft or Mushy Spots

A fresh spaghetti squash feels firm and hard all over.
 
If you press on it and it gives way, or you notice soft mushy spots, that’s a strong sign it’s going bad.
 
Moisture and soft spots usually mean the squash is rotting from the inside out.
 

2. Mold or Dark Discoloration

Any visible mold, black spots, or dark patches on the skin means your spaghetti squash has gone bad.
 
Even a small patch of mold means you should toss the whole thing, because mold spreads fast and can run deep into the flesh.
 

3. A Foul or Off Smell

A good spaghetti squash smells earthy and neutral.
 
If it smells sour, musty, or just plain off, it’s past its prime.
 
Trust your nose here, because smell is often the clearest signal that spaghetti squash has gone bad.
 

4. Slimy Texture Inside

Once you cut it open, the inside strands should be crisp and firm.
 
If the inside feels slimy or sticky, that spaghetti squash has gone bad and isn’t safe to eat.
 

5. Brown or Discolored Flesh

Fresh spaghetti squash flesh is a bright, pale yellow.
 
If the inside has turned brown or looks dull and grayish, it’s a clear sign the squash has gone bad.
 

How to Store Spaghetti Squash So It Lasts Longer

Proper storage is the biggest factor in how long before spaghetti squash goes bad.
 
Get the storage right, and you’ll get weeks of extra life out of it.
 
Here’s how to do it:
 

1. Keep It Whole in a Cool, Dark Place

Leave your whole spaghetti squash in a cool, dark spot like a pantry or cellar.
 
Aim for a temperature between 50 and 60°F, and keep it away from direct sunlight.
 
Don’t store spaghetti squash near apples or bananas, because those fruits release ethylene gas that speeds up ripening and spoilage.
 

2. Refrigerate Cut Spaghetti Squash

Once you cut into your spaghetti squash, wrap the unused portion tightly in plastic wrap or place it in an airtight container.
 
Store it in the fridge and use it within 3 to 4 days.
 
This slows down how fast your cut spaghetti squash goes bad.
 

3. Freeze Cooked Spaghetti Squash

If you’ve cooked more than you can eat, freezing is the way to go.
 
Spread the cooked strands on a baking sheet, freeze them, then transfer to freezer bags.
 
Frozen cooked spaghetti squash lasts up to 10 to 12 months, so it won’t go bad nearly as fast.
 

4. Check on It Regularly

Even in perfect storage, check your spaghetti squash every week or two.
 
Catching a soft spot or a bad smell early means you can use the good parts before the whole thing goes bad.
 

So, How Long Before Spaghetti Squash Goes Bad?

Spaghetti squash goes bad after about 1 to 2 months when stored properly, while cooked spaghetti squash goes bad in just 3 to 5 days.
 
The signs that spaghetti squash has gone bad include soft spots, mold, a foul smell, slimy flesh, and brown discoloration.
 
Store whole spaghetti squash in a cool, dark place and refrigerate or freeze the cut or cooked portions to keep it fresh as long as possible.
 
Hope this helped you understand how long before spaghetti squash goes bad and how to store it so you get the most out of every squash.
