How Long Can You Store Potatoes? Potatoes that haven’t been cooked can last anywhere from a few weeks to a few months. Potatoes can be refrigerated for 3 to 4 days after cooking, or frozen for up to a year.

How Do You Know When Potatoes Go Bad?

  • Aging Symptoms: Potato skin ages, sags, and develops spots in the same way that human skin does. While these are characteristics of a happy life in individuals, they are red flags in the case of bad potatoes. Although a little age won’t ruin the taste of potatoes, it’s better to toss out any that have wrinkled, sagging skin or a mushy feel, or if they’re wet in the bag.
  • Spoilage odor: The scent of fresh potatoes is earthy and starchy. This aroma changes as they deteriorate, turning bitter and rotten. On the surface, potatoes may appear to be fine, but they are rotten on the inside. If you see a potato in the grocery that appears to be fine but smells off, don’t buy it. If this happens at home, simply cut the potato open to examine if the ruined portion is tiny enough to take out and dispose of, or if the entire potato must be tossed. One blemished spot does not necessitate discarding the entire potato; it is entirely acceptable to eat the undamaged portion assuming there are no dark stains. To inspect the potato’s interior for the first signs of spoilage, simply cut it into smaller pieces.
  • Green Spots and Shoots: Because potatoes do not become entirely inactive after being harvested, they frequently sprout little sprouts known as eyes. Because many mass-produced retail potatoes are treated with a chemical that inhibits sprouting, this is especially true of organically grown or farm-stand potatoes. If the potato otherwise looks and smells fresh, remove the little sprouts before cooking it. Long-sprouting potatoes, as well as those with other signs of aging, should be rejected. Just before sprouts form, green dots appear. Because these spots carry moderate toxicity, small ones should be cut away, while big patches of green should be discarded.

How Long Do Potatoes Last At Room Temperature?

Whole, uncooked potatoes can last up to two months if kept in a cool, dark place (warmer than the fridge but cooler than room temperature). However, unless you have an unheated cellar, you’ll have to settle for room temperature. To keep them fresh, store them loosely covered in a paper bag, mesh bag, or cardboard box. Potatoes can be stored at room temperature for up to two weeks.

How Long Do Potatoes Last In The Fridge?

While we’ve already established that the fridge isn’t the ideal location to keep potatoes, there are situations when you don’t have a choice. You may want to store your potatoes in the refrigerator due to a lack of pantry space or hot/humid environments. If you prefer to keep your potatoes in the refrigerator for any reason, they will last for three to four weeks, although they will develop a sweet flavor when cooked.

Can You Freeze Potatoes?

Yes, you can freeze potatoes, and you should if you have an increased number of spuds. However, one thing to keep in mind is that you should only freeze prepared or partially cooked potatoes because raw potatoes contain a lot of water. This water freezes, making the potatoes mushy and grainy when thawed. Cut raw potatoes should be stored in a bowl of cold water and kept refrigerated. They’ll last for another 24 hours. Finally, cooked potatoes will keep in the fridge for three to four days, as will all leftovers.

How To Freeze Potatoes?

  1. Peel: This step is optional, but it is recommended because blanching works best when the skin is removed. It’s a good idea to cube your potatoes now if you plan to mash them once they’ve thawed.
  2. Blanch: Fill a pot halfway with water and salt it. Bring the water to a boil in a large pot over high heat. Place the potatoes in the water after it has reached a boil. Place the potatoes in the water once it is boiling. Blanching duration varies according to the size of the potatoes or potato pieces, ranging from three minutes for baby potatoes or little cubes to ten minutes for big russets. To stop the cooking process, remove the potatoes from the boiling water and quickly plunge them into an ice bath.
  3. Dry: After the potatoes have cooled fully, drain them in a colander. Place them in a single layer on a kitchen towel when they’ve drained. To absorb excess moisture, pat with paper towels.
  4. Flash freeze: Arrange the potatoes in a single layer on a cookie sheet that has been lined. Freeze for at least 6 to 12 hours, or overnight.
  5. Freeze: When the potatoes are frozen, place them in freezer-safe storage containers with the date labeled on them.

How Long Does It Take To Freeze Potatoes?

Freezing potatoes in the freezer requires at least 6 to 12 hours.

How Long Do Potatoes Last In The Freezer?

While cooked potatoes do well in the freezer, raw potatoes do not, so it’s best to cook them prior to freezing. Cooked potatoes will survive 10 to 12 months in the freezer if they are stored in a freezer-safe bag or airtight container.

How Long Do Potatoes Last In Cold Storage?

Potatoes can be stored for up to 8 months in cold storage. Potatoes are prepared for cold storage by reducing the temperature by 0.5 ᵒC per day. Seed potatoes are best stored in cold storage at 2 to 4°C, while other types should be kept at 4 to 10°C. Controlling carbon dioxide, however, is as important as controlling the cold room temperature and humidity in cold storage. Carbon dioxide levels should be kept under control and within a certain limit.

Best Way To Store Potatoes?

The best way to store raw potatoes is to place them in a cool, dark, and relatively dry environment. This will prevent them from sprouting for as long as possible, while also slowing the growth of mold. Raw potatoes should not be kept in the refrigerator or freezer. This can cause browning, softening, and an increase in the sugar content of the potatoes.
