Anyway, potatoes are just one of the foods that I usually buy in bulk. It is my favorite vegetable since it is so versatile, there are countless ways I can use it in the kitchen. However, shopping in bulk would also mean that the potatoes you purchased about a week ago could be stored in the cupboard for a long time.

Now it leads me to the question how long do potatoes last? This is important to keep your kitchen safe and to prevent any health risks that a rotten potato can bring. So I made my research and today, I will be sharing what I’ve learned in this article.

If you want to know the answer, then please keep on reading below.

How Long Can You Keep Your Potatoes?

So we’ve come to the big question, how long do potatoes last? The average shelf life of potatoes actually depends on a number of factors such as the type of potato, the method involved in preparing it as well as the place where you are storing it.

When it comes to fresh, raw potatoes, they can actually last for one to two weeks, as long as you are storing them in a normal room temperature. While raw sweet potatoes can last much longer at about three to five weeks, they can even last up to three months when stored in the refrigerator. 

Cooked potatoes, on the other hand, have a short storage life. Leaving them at a room temperature that ranges between 40 to 140-degrees Fahrenheit can turn them rancid within just two to three hours.

How To Tell If The Potatoes Have Gone Bad 

There are plenty of signs to tell if the potatoes have already gotten bad. Below are just a few of the most common traits.

  • 1
    There’s mold formation. Wet potatoes often develop molds. If this happens, you have to throw the potatoes out immediately.
  • 2
    It doesn’t smell good. Its appearance will start to wither and emits a rotten or unpleasant odor.
  • 3
    There are soft spots. You will see soft spots in areas that also have discoloration.

Storing potatoes in an area where there is so much humidity can start to grow white sprouts, this indicates that the starch which can be found naturally inside the potato has started to convert into sugar. 

Well, technically, this doesn’t mean that the potato has already gotten bad, you just have to cut off the sprouts before using the vegetable. Just simply use any knife to get rid of that sprout; however, the quality of the potato may reduce. If there’s wrinkling that comes along with the sprouts, you should quickly throw the potato away.

Also, if you will leave the potato exposed into the direct light, whether it is natural sunlight or artificial, you will start to see green spots beginning to develop and then the potato will have a bitter taste. Green spots on potatoes could actually be a sign that the toxin solanine has been developed and is present in the vegetable. You need to be careful since this toxin can cause poisoning. The signs of solanine poisoning are vomiting, diarrhea and headaches.

So make sure that you remove any green spots before using the potato, some people even find it best to just fully get rid of the potatoes altogether. You need to dispose of any bad potato as quickly as possible too, or else it will speed up the spoilage of any other potato in the same storage.

How To Prolong Storage Life of Potatoes

But I have some good news for you! There are actually so many ways that you can do just to extend the storage life of potatoes. The ideal storage conditions are as follows:

  • Low humidity level
  • Cold temperature, about 45 to 50-degrees Fahrenheit
  • No light

I know this kind of weird, but the best place to store your potatoes is at your home would actually be in the basement or the cellar. You can just spread them over the hard surface or place them in a basket or a brown paper bag; just make sure you allow air circulation, this would be very beneficial.

Here’s also another trick that I’ve learned and this involved some sweet apple. I know you hate those ugly sprouts that form on your potatoes within just a couple week. Well, it turns out that an apple a day can keep these sprouts away and help the potatoes last longer. This is because ripe apple emits ethylene gas which can hinder the growth. This is such a good news as sprouts in potatoes can be a sign that they are already losing the valuable nutrients.

If there are potatoes in the group that have gotten bruised or have already been cut open, make sure that you quickly remove them from the rest as they will oxidize and make the whole group go rotten sooner than expected. 

For the potatoes, you've already cut but can no longer use for your recipe, prolong their storage life by placing the potatoes into a bowl filled with salted water as quickly as you cut them.

Final Thought

Well, we know for a fact that potatoes don't come cheap, this is actually my main reason why I include this vegetable in the list of foods I buy in bulk. So if you're like me, who is always trying to buy in several dozens just to save a few bucks, then you have to make sure you know how long do potatoes last and how to store them properly.
