How Long Are Potatoes Good For? Best Way To Store Them

You’re fixing dinner for your family and reach for the potatoes, and you begin to wonder if the spuds are still good. Most experts agree that the answer to the question “How long are potatoes good for?” is generally about three to five weeks when stored in the pantry. However, there are several factors that affect this timeline, such as storage, temperature and type of potato.

Since it can be difficult to remember when you bought those spuds, here are a few signs that can help determine whether or not the potatoes are still good.

Three to five weeks is the average shelf life of potatoes, but this time frame can be shortened or increased, and it varies from one type of potato to the next.

You can increase this time by storing the potatoes in the refrigerator. Below is the lifespan of each kind of potatoes when you store them in the fridge.

There are many signs to tell whether you potatoes have gone bad. Here are some of the most common traits:

Potatoes stored in a climate with too much humidity can begin to grow white sprouts, which is an indication that the starch found naturally inside the potato has begun to convert into sugar. This doesn’t mean the potato is bad, and the sprouts can simply be cut off before use. Just simply use, say, your utility knife to eliminate the sprouts.

However, the potato’s quality may become diminished. If the sprouts are accompanied by wrinkling, you should throw away the potato.

When a potato is exposed to direct light (sunlight or artificial) for an extended period of time, it will begin to develop green spots and possibly a bitter taste. In fact, green spots on potatoes could be a sign that the toxin solanine is present. Signs of solanine poisoning are diarrhea, vomiting and headaches.

Any and all green spots should be removed before using the spud, and some people find it best to just discard green potatoes all together. One spoiled potato can accelerate the spoilage of any other potato it is stored with, so you should remove and discarded any bad potato as soon as possible.

Proper Ways To Store Potatoes

According to the University of Idaho, the common temperature in homes of 65 to 75 degrees Fahrenheit is too high for the optimum storage temperature of potatoes, which is 42 to 50 degrees Fahrenheit. Because of this, you should store potatoes of all types in a cool, dark area that is well ventilated.

When you store potatoes in an area with higher temperatures and lower humidity, the potatoes can sprout and shrink. This is because potatoes are 80 percent water, and dry, hot climates will cause the water to evaporate.

Storing potatoes in the refrigerator will increase their shelf life, but it will also cause the starches naturally found in the vegetable to turn to sugar, which will cause the potatoes to have a sweet taste and possibly darken quicker when frying. You can reverse this process by letting the potatoes sit out at room temperature for 7-10 days.

Because wet potatoes increase the chance of mold growth, never wash the vegetable before storing it. Instead, wait until right before using the potatoes to wash dirt and debris off the surface. If you’re storing potatoes in a bag, choose a dark-colored bag, such as a brown paper bag, that has holes cut into it to allow for airflow.
