3. Cut Spaghetti Squash in the Fridge

Once you cut into a spaghetti squash, it goes bad much faster.
 
A cut spaghetti squash lasts about 5 to 7 days in the fridge.
 
Wrap it tightly in plastic wrap or place it in an airtight container to keep it fresh.
 

4. Cooked Spaghetti Squash in the Fridge

Cooked spaghetti squash strands last about 3 to 5 days in the fridge.
 
Store them in a sealed container so they don’t dry out or absorb other smells.
 
After that window, the texture gets mushy and the flavor fades.
 

5. Frozen Spaghetti Squash

If you freeze cooked spaghetti squash, it can last 8 to 12 months.
 
So freezing is the winner if you want to extend how long before spaghetti squash goes bad.

Signs Your Spaghetti Squash Has Gone Bad

Knowing how long before spaghetti squash goes bad is helpful, but you should also watch for signs it’s already spoiled.
 
Here’s what to look for:
 

1. Soft or Mushy Spots

A fresh spaghetti squash feels firm and heavy.
 
If you press it and it gives way or has soft spots, it’s going bad.
 

2. Mold or Dark Patches

Any visible mold, dark patches, or fuzzy spots mean it’s time to toss it.
 
Don’t try to cut around mold on a squash because the spores can spread deep inside.
 

3. A Bad Smell

A spoiled spaghetti squash gives off a sour or musty odor.
 
If it smells off, that’s a clear sign it has gone bad.
 

4. Slimy Texture

When you cut it open, the inside should be firm and stringy.
 
If it’s slimy or watery, it has gone bad and shouldn’t be eaten.
 

5. Discolored Flesh

Fresh spaghetti squash flesh is a pale yellow to light orange.
 
Brown or grayish flesh means it’s past its prime.

2. Pick a Cool, Dark Spot

A temperature between 50°F and 60°F is ideal for whole squash.
 
Avoid spots near the stove, dishwasher, or sunny windows.
 

3. Refrigerate After Cutting

Once cut, move it straight to the fridge.
 
Wrap it tight or seal it in a container to lock in freshness.
 

4. Freeze Cooked Strands

For long-term storage, cook the squash, shred the strands, and freeze them in portion-sized bags.
 
This keeps cooked spaghetti squash good for up to a year.

Always inspect your squash before cooking.
 
If it shows any of the bad signs above, toss it instead of risking a stomach ache.
