How To Know When Yellow Squash Is Bad

You know yellow squash is bad when it feels soft or mushy instead of firm.
 
If you’ve been wondering how to know when yellow squash is bad, the answer is usually in the touch, the smell, and the look of the squash.
 
A good yellow squash should feel heavy for its size and have smooth, shiny skin.
 
Once it starts to go bad, though, you’ll notice changes pretty quickly.
 
In this post, we’ll walk through the signs that tell you when yellow squash is bad, so you never have to guess again.
 
Let’s dive in.
 

Signs That Tell You When Yellow Squash Is Bad

 
When yellow squash is bad, your senses will let you know.
 
Here are the biggest signs to watch for.
 

1. Soft or Mushy Texture

 
The quickest way to know when yellow squash is bad is by squeezing it gently.
 
Fresh yellow squash should be firm, with just a tiny bit of give.
 
If it feels soft, squishy, or mushy, that yellow squash is bad and past its prime.
 
A spongy texture usually means the inside has already started to break down.
 

2. Wrinkled or Shriveled Skin

 
When yellow squash is bad, its skin starts to wrinkle and look dull.
 
That smooth, glossy surface you see on fresh squash slowly turns leathery as it loses moisture.
 
If your yellow squash has deep wrinkles or shriveled spots, it’s a clear sign the squash is bad.
 

3. Dark Spots or Mold

 
Dark, sunken spots on the skin are another sign that yellow squash is bad.
 
These spots often start small and spread as the squash spoils.
 
If you spot fuzzy mold in white, green, or black, toss that yellow squash immediately.
 
Mold means the squash is bad all the way through, even if only a small patch is visible.
 

4. A Sour or Musty Smell

 
A fresh yellow squash barely smells like anything at all.
 
When yellow squash is bad, though, it gives off a sour, musty, or slightly fermented odor.
 
If the smell makes you pull back, that yellow squash is bad and shouldn’t be eaten.
 

5. Slimy or Sticky Surface

 
Sometimes a yellow squash looks fine but feels sticky or slimy when you pick it up.
 
That slick coating is a telltale sign that yellow squash is bad.
 
Slime usually means bacteria have taken over, so don’t try to wash it off and cook it anyway.
 

How to Tell If Yellow Squash Is Bad After Cutting It Open

 
Sometimes the outside of a yellow squash looks okay, but the inside tells a different story.
 
Here’s how to know when yellow squash is bad once you cut into it.
 

1. Brown or Discolored Flesh

 
Fresh yellow squash has pale, creamy flesh with small, tender seeds.
 
If the inside looks brown, dark, or mushy, that yellow squash is bad.
 
Brown flesh means the squash has started to rot from the inside out.
 

2. Large, Tough Seeds

 
When yellow squash is bad, the seeds often become large and tough.
 
Overripe squash develops hard, woody seeds that aren’t pleasant to eat.
 
While large seeds alone don’t mean the squash is spoiled, they often go hand in hand with a bad squash.
 

3. Hollow or Dry Interior

 
An old yellow squash can turn hollow, dry, and stringy inside.
 
If the flesh looks shriveled or has big empty pockets, that yellow squash is bad.
 
This happens when the squash loses moisture over time and starts breaking down.
 

How Long Yellow Squash Lasts Before It Goes Bad

 
Knowing how to store yellow squash can help you avoid the question of when yellow squash is bad.
 
Here’s a quick rundown of how long it usually lasts.
 

1. On the Counter

 
Fresh yellow squash lasts about 3 to 5 days at room temperature.
 
Keep it out of direct sunlight and in a cool, dry spot for the best results.
 

2. In the Fridge

 
In the crisper drawer, yellow squash stays fresh for about 1 to 2 weeks.
 
Don’t wash it before storing, since extra moisture speeds up spoilage.
 

3. In the Freezer

 
Blanched and frozen yellow squash lasts up to 10 to 12 months.
 
But once thawed, the texture changes, so it’s best used in soups or casseroles.
 

So, How Do You Know When Yellow Squash Is Bad?

 
You know when yellow squash is bad when it feels soft, looks wrinkled, smells sour, or shows mold and dark spots.
 
If any of those signs show up, it’s best to throw that yellow squash away.
 
Trust your senses, and when in doubt, toss it out.
 
Using these tips, you’ll always know exactly when yellow squash is bad.
