Can Potatoes Be Stored In The Refrigerator? [Peeled, Baked, Etc.]

Potato storage depends on whether the potatoes are raw, cut or cooked. Cool storage helps, but the guidance differs by type and preparation. Can potatoes be stored in the refrigerator?

Cooked potatoes need prompt refrigeration. For whole raw potatoes, guidance differs: the U.S. FDA recommends a cool, dark place outside the refrigerator, while the UK Food Standards Agency says refrigerator storage is acceptable under its updated advice.

Let’s look at this in more detail now.

What Does Current Advice Say About Raw Potatoes?

The U.S. FDA still recommends storing raw potatoes in a cool, dark place outside the refrigerator to limit acrylamide formation during later high-temperature cooking.

The UK Food Standards Agency has updated its advice: it says recent research found that home refrigerator storage does not materially increase this potential compared with cool, dark storage. It allows either option.

Follow the guidance for your location. Avoid cooking potatoes to a dark brown color, and discard badly spoiled potatoes. This raw-potato advice does not replace the need to refrigerate cooked potatoes.

How To Store Potatoes If It Gets Too Warm Where You Live?

Warm and humid storage conditions aren’t ideal for potato storage.

They will not last as long as they should and will sprout when the ambient temperature increases.

Too much moisture will also encourage them to sprout quickly.

Potatoes do best in temperature and humidity-controlled spaces, like root cellars or pantries. It should be away from sunlight.

Sunlight promotes photosynthesis, and too much exposure can speed up the development of shoots.

However, if you don’t have such a space and it gets too warm where you live, you can refrigerate or freeze them after cooking.

After cooking, cool potatoes promptly in shallow containers and refrigerate them; do not leave them out to cool completely.

Important Storage Tips To Extend The Life Of Potatoes

The following storage tips will make your potatoes last longer.

• Ensure good air circulation: Place potatoes in a mesh bag or basket that allows proper airflow. Also, ensure that the storage space is well-ventilated to prevent the build-up of moisture. Too much moisture can also lead to mold formation, making the potatoes unfit for consumption.
• Store them in a dark place: It’s not a good idea to keep potatoes on the countertop, where they are exposed to light. The presence of sunlight will encourage photosynthesis. So the potatoes will produce new growth. The formation of shoots and roots will make them unsafe for consumption.
• Choose suitable storage: Keep potatoes away from heat and damp conditions, and check them regularly for spoilage and sprouting. Choose a well-ventilated container and remove spoiled potatoes promptly.

Do Potatoes Need To Be Refrigerated After Being Cut?

Potatoes are highly prone to oxidization when cut. They turn brown and look very unattractive within minutes of being cut.

Hence, it’s not a good idea to cut potatoes ahead of time.

Refrigeration slows spoilage, but cut potatoes still have a short storage life.

However, you can refrigerate them by placing the potatoes in a bowl of cold water.

They will hold up for 24 hours when stored in this manner.

Prepare only what you need and use refrigerated cut potatoes promptly.

Do Cooked Potatoes Need To Be Refrigerated?

Yes. Refrigerate cooked potatoes within two hours, or one hour above 90°F (32°C). Keep the refrigerator at 40°F (4°C) or below and use leftovers within three to four days. Divide larger batches into shallow containers so they cool quickly.

Do Baked Potatoes Need To Be Refrigerated?

Eat baked potatoes hot or refrigerate leftovers promptly, within the same two-hour or hot-weather one-hour limit. Remove baking foil before refrigeration; do not leave foil-wrapped potatoes at room temperature. Use refrigerated leftovers within three to four days.

Can Peeled Potatoes Be Stored In The Refrigerator?

Like cut potatoes, peeled potatoes also oxidize when exposed to air. They turn brown and look very unappetizing.

Leaving them at room temperature speeds up the oxidization process.

However, storing them in the refrigerator doesn’t halt this process. It will only slow it down.

Wrapping peeled potatoes in aluminum foil or placing them in an airtight bag will not stop them from changing color.

Instead, you should submerge the peeled potatoes in water and refrigerate the entire bowl.

Keep peeled potatoes submerged in water in the refrigerator and use them within 24 hours.

For longer storage, use a tested freezing method rather than extending the water soak.

Can White Potatoes Be Stored In The Refrigerator?

The location-specific raw-potato guidance above also applies to white potatoes. Their color alone does not determine storage safety. Refrigerate cut or cooked white potatoes as described above.

Can Russet Potatoes Be Stored In The Refrigerator?

Use the same raw-potato guidance for russets. Follow U.S. FDA cool, dark storage advice or the updated UK refrigerator option for your location; refrigerate cooked russets promptly.

Can Seed Potatoes Be Stored In The Refrigerator?

If you wish to use seed potatoes for planting in the upcoming season, you must store them properly.

To be viable, they should go for months without developing sprouts or spoiling.

The best way to store seed potatoes is in a cool, dark, and dry space.

The storage temperature should be between 40°F and 42°F.

The seed potatoes shouldn’t brush against each other and develop cuts.

Additionally, they shouldn’t be exposed to humidity or heat.

It’s not necessary to refrigerate seed potatoes; they will hold up well outside.

Refrigerator temperatures are below the ideal storage temperature range for seed potatoes.

Hence, it’s better to store them outside.

You will have to move the seed potatoes out of storage to a warmer space a few days before planting.

They need temperatures between 50°F and 55°F during this phase.

This exposure to warmth will kick them out of dormancy and prepare them for sprouting.

Can Sweet Potatoes Be Stored In The Refrigerator?

Although sweet potatoes have the term “potato” in their name, they’re only distantly related to potatoes.

Nevertheless, sweet potatoes are also root vegetables, and their storage requirements are like normal potatoes.

The best way to store sweet potatoes is in a dry bin or basket in a cool section of the pantry, away from heat and sunlight.

They will keep for several weeks when you store them like this.

Whole raw sweet potatoes are different from regular potatoes: cold storage can cause chilling injury, so keep them in a cool pantry rather than the refrigerator.

Another problem with refrigerating sweet potatoes is that the cold fridge environment makes their center hard.

This will reduce their appeal when cooked.

Now, if you must refrigerate sweet potatoes, cut them into pieces and submerge them completely in water.

Store them in the same container overnight and use them the next day.

It’s better to cook sweet potatoes before refrigerating them.

Use refrigerated cooked sweet potatoes within three to four days.

If you want your sweet potatoes to last even longer, you can freeze them.

For freezing, follow the National Center for Home Food Preservation’s sweet-potato method: cook until almost tender, then prepare and package as directed. A brief two- to five-minute blanch is not an equivalent method.

Alternatively, you can also flash-freeze sweet potatoes before packing them into bags.

It will make it more convenient to take them out later and use them.
