Picking A Butternut or Spaghetti Squash

When it comes to picking butternut and spaghetti squash, there are certain ‘rules’ that apply to both. 

In both cases, you will need to look for a squash that is ripened to the perfect degree. Immature butternut and spaghetti squash are edible. However, you will not get the true taste of winter squash. 

Overripe squash, on the other hand, is a waste of money. They are mushy inside and don’t have as rich of a flavor. 

Here is what you should pay attention to when picking butternut or spaghetti squash. 

  • Look for a weighty one. A butternut or spaghetti squash should feel ‘right’ for its size. If the squash feels light, look for another one as it is probably not ripe yet. 
    • You can also use the knocking method. If you knock and hear a hollow sound, grab the squash. It’s ready. 
  • Look for the right color. Color is one of the key indicators of ripe winter squash. 
    • For butternut squash, the darker it is the better. The perfect color for butternut squash is dark beige. 
    • As for the spaghetti squash, a perfectly ripe spaghetti squash should have a bright yellow color. 
  • Check the skin. Closely examine the skin of butternut and spaghetti squash. There should be no indentations or cracks on the skin. 
    • Green spots or stripes on a squash indicate that it is not fully ripe. 
    • Another way of checking whether spaghetti or butternut squash is perfectly ripe, try to pierce it with your fingernail. If you can’t do it with ease, it indicates that the squash is not overripe. 
  • Pay attention to the stem.  Never buy squash that has a missing stem as chances are high that it is rotten. 


There are almost no differences in storing spaghetti and butternut squash. Here’s what you should do.

  • Store them somewhere dry and cool. Humidity will make them go bad quickly.  
  • Don’t keep winter squash near fruits that produce ethylene gas while ripening. These include apples, bananas, figs, apricots, etc. 
  • Make sure the skin of butternut and spaghetti squash is dry. Water may contribute to fungi and bacteria growth. 

If you store them correctly, butternut and spaghetti squash will keep well for up to three and two months respectively.
