They’re not always trendy, but they’re dependable. They’re comforting, versatile, and always crowd-pleasing. No, we’re not talking about a pair of sneakers. We’re talking about potatoes. This root vegetable has a pretty long shelf life, and even longer when stored properly. The key is to store potatoes in a cool dry place, like in the cabinet of a pantry, in a paper bag or cardboard box. It’s important to keep potatoes at the cool, ideal temperature (but not, surprisingly, the fridge) to prevent them from turning green, getting soft spots, or pre-maturely sprouting. Once this happens, it’s a sign that they’re past their peak. But we’ll get into all of that ahead a little later. For now, learn about the conditions that cause potatoes to ripen and how to prep them for long term storage.

The Science Behind the Spuds

Though potatoes are certainly, well, cut off upon harvest, they continue to breathe (spooky, right?) and, in a way, live on the shelves of grocery stores and in your home. As oxygen from the environment combines with the sugars in patats, it gets respired from the roots as carbon dioxide and water. Storing potatoes in a cool, dark (but not forgotten) place hugely decelerates this inevitable decomposition, protects against sprouting, and, to some degree, sweetens the tubers.

It’s also important not to store potatoes and onions together. Though they seem like two peas in a pod as they’re often both called for in the exact same recipes. However, storing them both together actually does more harm than good. Both of these root veggies contain a lot of moisture, which can lead to faster spoilage. Combined, they produce an ethylene gas that will speed up the ripening process. Instead, keep them apart in an area that has good air circulation to maintain their long shelf life. 

How to Store Potatoes

Although you shouldn’t put potatoes in the fridge, potatoes will still keep the longest when stored in a cool, dark place—specifically somewhere that has a cold temperature of about 50°F and 90 to 95 percent humidity, like, you know, a temperature- and humidity-controlled root cellar. You know the one that’s right next to your massive wine cellar? So just toss them down there, along with your turnips, onions, and carrots, and call it a day. They’ll be good for weeks, if not all winter long.

Shop the Story

Oh wait, I don’t have a root cellar (do you?). Have no fear: Here are four of our best storage tips—root cellar not required—for happy, sweet, and dry taters.

1. Keep Them Out of the Sunlight (but Not Out of Sight).

Don’t store potatoes out in the open on the countertop. Keep them in a drawer, in a basket, in a closet, in a paper bag, or in a bamboo vegetable steamer—anywhere that's dark—and they should last for one to 2 weeks. A clear plastic bag, like that kind that potatoes are packaged in, are actually not ideal for storing spuds. Potatoes are plants, after all. If they see sunlight, they will do their photosynthesis thing and turn green, and eventually wrinkle and rot.

And remember, out of sight, out of mind—keep them in a trafficked-enough part of the pantry so you don’t forget about them.

2. Make Sure They Still Have Airflow

Either transfer your potatoes to a paper or mesh bag, like the Five Two Organic Cotton Reusable Produce Bags or a well-ventilated container. (They will be releasing carbon dioxide and water in the form of vapor, so things can get a little too damp.) If you’d like to keep them in the plastic bag they came in, make sure it’s well-perforated and that the top isn't tightly sealed.

3. Don’t Store Them Next to Your Onions

We touched on this earlier, but let’s get into the nitty gritty. It’s tempting to toss both your potatoes and onions together in a basket in your pantry and be done with it—after all, they both like to be stored basically the same way. But resist temptation, because keeping them together (along with potatoes and avocados, potatoes and bananas, and potatoes and apples) might encourage your potatoes to sprout.

4. Avoid Warm Spots

Even if you don't have a cooler storage location than your kitchen, take care to avoid the warmest spots in the room: Don’t store your potatoes next to the oven, under the sink, or on top of the fridge.

When warmer than their ideal storage temperature, potatoes will start to sprout, but colder isn’t necessarily better either. In On Food and Cooking, Harold McGee explains that when kept at colder temperatures (i.e. your refrigerator), “their metabolism shifts in a complicated way that results in the breakdown of some starch to sugars.” This means potatoes stored in the refrigerator will taste sweeter over time, and when cooked they are more likely to come out an unappetizing shade of brown.

Signs That Potatoes Have Gone Bad

There are a few easy things to look for if you’re wondering, “have my potatoes gone bad?” Mold, black spots, and soft spots are easily tells. Dr. Benjamin Chapman, an associate professor and food safety specialist at North Carolina State University, also recommends avoiding consuming potatoes that are wrinkled, soft, or shriveled. It’s not necessarily harmful to eat, but think of it like eating any other rotten fruit, such as bananas or apples. The flavor and texture will not be at their best and it’s just all-around unappetizing.

As for green potatoes, Dr. Chapman says that’s a sign that the spuds have been exposed to too much light and will give off a bitter flavor and can even be irritating to the digestive system.

I forgot to mention just how cold a true outside root cellar would be! Before central heating,
especially in Europe stoves we’re used in each room, and people were accustomed to cold
indoor temperatures all winter. The root cellars were dug into the ground near the house, and
all stored food would endure near freezing temperatures for many months. None of my relatives ever complained about the quality of the food in the Spring, and were happy to have
It. So why in the world would a temperature controlled refrigerator be too cold for root vegetables?
Dordy B. August 12, 2023
I think the refrigerators today are climate controlled for different foods. I have always kept
potatoes in the refrigerator in the lower drawers that are not as cold as the top section where
milk, cream and other beverages as kept. I can’t imagine putting potatoes in warm drawers
or baskets as all food will rot in time if not refrigerated. And keeping food in the basement is
unnecessary in our modern world. Seems like a lot of contributors are listening to great grandma, who would have loved the convenience of the modern refrigerator. I can’t imagine
my potatoes growing sprouts in two weeks. My potatoes lasts for months in the refrigerator,
just like in my Norwegian great grandmothers root cellar!

My mom always kept potatoes in the basement in a single layer of newspaper. These days everyone doesn't have easy access to a basement or newspaper so I have never found a perfect method of potato storage.

This is so NOT true in my house. I store potatoes, squash and canned goods down in a cool dark dry cabinet in my home and they sprout within days of being placed there. I give up😱
carole March 16, 2022
I'm confused! At the top of this story, it says "how to store potatoes so they last for month, (yes Months). However in the body of story, it says they can last only 1 to 2 weeks??? Which is it?
John January 4, 2022
Article unhelpful. It did not cover “sprouting buds”, and I still don’t know where to store them. They tend to grow buds very quickly in here and my house is cool. So, in short, this article leaves a lot to be desired :( I guess I will have to think about building a cellar, lol, in Florida.
Georgine August 13, 2021
“Plus, find out once and for all if it’s safe to eat sprouted spuds.” This isn’t mentioned at all in the article—just how to avoid sprouting!

Put an apple in your potato basket. It puts off an enzime that keeps them from sprouting.
liguy January 25, 2016
It is not an enzyme, it is a gas called ethylene gas
ggwanda88 January 25, 2016
Sorry, thanks for the correction.
HalfPint January 5, 2022
This is a bit late but:

It's ethylene gas which does not make any sense because ethylene gas helps fruit to ripen. So you are not going to want to add an apple to the potato basket if you don't want it to sprout.

Happy to see this, but I repeat a question I've posted before with no definitive answer: how close is "too close" for onions & potatoes? Separate baskets I get. If the baskets are next to each other, is that too close? How about on opposite ends of, say, a 4' shelf? Same side of closet, different shelf? Opposite sides of, say, a 3' wide closet/pantry? Or not in the same pantry space at all? I'm an organizer and have never been able to say one way or the other for myself or my clients...please tell me!

Hi there! Well, i have always stored onions, potatoes, green cabbages, squashes, and pumpkins (yes, i buy them to eat them) in real baskets, each in their own basket, all over my living room, which has no direct sunlight, and is always the coolest area of my apartment. They do not ever sprout, and stay fresh and beautiful for a lobg time. I did have an actual root cellar with my apt. In eastern europe, so when i moved here to usa i asked my friends back there...what to do with no cellar? And they advised...go out and buybig,natural baskets, keep in coolest spots. I have a tile floor in my living and dining area, itscool even in summer, so i just fi d strategic spots to place my veggie baskets on the floor. As a matter of fact, the very first thing i do wheni get home with e groceries, is get the vegs out of their bags and into their baskets. Friends tell me it also makes my apt. Look very rustic and unusual in a nice way. About the fridge? I personally have, in the past, totally ruined tomatoes and potatoes in the fridge. I learned the hard way...LOL! Never again!

I suppose the operative phrase is "over time"- I've refrigerated a lot of potatoes over the years and never had one come out an unappetizing shade of brown, or anything other than potato colored. Maybe if you left them in there six months. Or maybe something happens with russets- I don't remember ever refrigerating those. If they're sweeter, it's not noticeable and anyway, I'm still mourning the long lost supersweet Yellow Finn.

An interesting recipe from Amanda (actually, her husband's), relies it seems on refrigerated potatoes: I'd never heard of anyone putting a potato in the refrigerator before I read that. ;o)
Greenstuff November 3, 2015
I didn't say anything when Amanda's husband's recipe was posted. It was probably prudent, because recently, someone on the Hotline (maybe it was oldunc!) pretty much told me that I was a scientist with not enough real work to do when I cautioned against storing potatoes in the refrigerator. Truth is I AM a scientist and I wouldn't store potatoes in the refrigerator. But clearly, it's worked for others, sometimes with delicious results.
Smaug November 4, 2015
Science mostly comes down to "try it and see what happens", so I guess I'm a scientist too. Not much of anything happened.

Just wondering IF storing potatoes in the fridge could lead to gummy mashed potatoes. I am aware that gummy mashed potatoes are the result of over beating &/ or, over cooking,as well as not draining well enough. However, i have also read that cold storage like the fridge can also cause that gluey, gummy mashed as well. Thoughts? Or references?
Lynda R. April 6, 2020
Don't store raw whole potatoes in the fridge. It's okay after they are cooked, though.
When I put some whole potatoes in the fridge, they turned blackish. I was very young when I did that! Only the one time....learn from your mistakes.
Trial & error. ;)
Lynda R. April 6, 2020
""gluey, gummy mashed" comes from the way they were badly mashed and has nothing to do with the fridge.
Perhaps, that person should read up on making mashed potatoes!
But, they should know what they did wrong!!
