At room temperature, on the counter, for example, potatoes will last up to two weeks. Undoubtedly, the best way to store whole, uncooked potatoes is outside of the fridge. Storing potatoes in the fridge will cause the starch to turn to sugar, giving them a sweet flavor that you don't want from your potatoes.
Keep Potatoes in a Cool and Dry Environment
As previously explained, potatoes should be placed in a cardboard box, mesh bag, or basket to ensure good ventilation. Store your potatoes in a cool, dark place (45 to 50 F is the ideal temperature range), such as your pantry or unheated basement.
Generally, potatoes last one to two months when stored in a cool, dry, dark and well-ventilated space (never under the sink!), such as the pantry, versus one to two weeks in the refrigerator, according to FoodSafety.gov's FoodKeeper app, the federal consumer resource for food safety.
The Science Behind the Spuds
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.
Instead use burlap sacks or breathable containers like paper bags, cardboard boxes, baskets and bowls to allow for air flow. Don't freeze raw potatoes.
You need to keep your potatoes in a dry, dark place. Exposure to light or moisture can bring on rotting in the skin. You'll also need to allow your spuds to be well-ventilated so avoid any airtight containers or spots – a netted bag or wicker basket should do the trick.
Storing potatoes the right way requires proper ventilation. Ziata recommends open containers (like open paper bags, baskets, and sacks), as these options will prevent excess moisture from accumulating. "Avoid airtight containers and sealed plastic bags, and never wash your potatoes before storing," she says.
Keep them in a cool, dry place away from light, like a dark corner of the kitchen or in a cabinet. Wherever you store them should be well ventilated. And, if possible, avoid storing them near other fruits (like bananas or onions) that can cause them to spoil faster.
What you don't want is to have your potatoes and onions in close proximity, as gases from the onions can hasten sprouting in potatoes. Kept in the dark: Davison says your potatoes should be stored inside a paper bag in a cool, dark, dry place. And as mentioned above, away from onions and their sprout-encouraging gases.
Sprouted potatoes that are still firm, have relatively small sprouts, and don't show any wrinkles or shriveling are okay to eat, as long as you cut off the sprouted parts and soft spots. However, there's still a chance you could get sick. If your potato is sprouted and shriveled up, then it's too far gone. Toss, it.
The long and short of it is that—yes! —sprouted potatoes are usually safe to eat. But you are going to want to trim those tiny growths before you cook the spuds. Keep reading to find out how to safely cook sprouted potatoes.
Check for soft spots, dark spots, sprouts, or green color. If the potato has little sprouts remove them, then prep potato for your dish. If there is a little green cut that off. If the potato has long spouts, is soft, wrinkled, or has lots of dark spots get rid of it.
So if you're wondering… can you store potatoes in a paper sack? Well, you sure can! As opposed to closed off airtight containers or zipped up plastic bags, open brown paper bags are a great way to store potatoes to allow for proper ventilation and air flow.
Store your potatoes in a cool, humid, and dark place (45 to 50 F is the ideal temperature range). If you have an unheated basement, that's a perfect spot for your potatoes. An insulated garage or shed might also work during the winter. Never store potatoes in the fridge.
You'll have to store your carrots in the refrigerator, but how you store them can actually make a difference. Raw carrots, when properly stored will usually stay fresh for around 3 to 4 weeks in the fridge.
Ripe tomatoes should still be kept at on your counter, uncovered, if you are going to enjoy the tomato in the next day or two. But any longer than that – the recommendation is to refrigerate. A so-so tomato is much better than a rotten, moldy tomato. Refrigeration will slow down the decay.
So, store your potatoes unpeeled and unwashed; in a cool, dry and dark spot like an enclosed kitchen cabinet away from the sink. Also, avoid keeping raw potatoes in the fridge – too cold, and the starch-to-sugar conversion starts up as well, ruining their texture, colour and flavour.
Onion bulbs and potato tubers both flourish underground, meaning that the vegetables require similar storage conditions — cool, dark, and ventilated environments — and they fare much better on a counter than in the fridge.
A basket, bowl, or paper bag is better than a plastic bag. A paper bag, basket, or large bowl are ideal for storing a pile of potatoes since they allow for plenty of air circulation.
There is no evidence that the special, breathable plastic wrap sold on 'microwaveable' potatoes transfers any residue or poses any adverse health concerns.
