You want to be able to eat your potato without worrying if you are going to get food poisoning or botulism. Here's how you can ensure that your baked potatoes are safe to eat. DON'T let your potato sit out in the open at room temperature for over four hours regardless of whether or not it is wrapped in aluminum foil.
A: NO! This is the wrong way to do it and is not food safe. Cooked starch foods like potatoes can grow germs if not kept either refrigerated and cold or hot over 140º F.
Shelf Life Tips
Properly stored, cooked potatoes will last for 3 to 5 days in the refrigerator. How long can cooked potatoes be left at room temperature? Bacteria grow rapidly at temperatures between 40 °F and 140 °F; cooked potatoes should be discarded if left out for more than 2 hours at room temperature.
Potatoes can last for up to several months in a cool pantry. If stored at room temperature, they are best if eaten within one to two weeks. Once cooked, keep them in the fridge for no more than three days.
Cooked potatoes should be reheated to a minimum of 165 F before eating to kill any bacteria. At room temperature, potatoes that have been cooked quickly grow bacterial colonies that cause them to spoil after 2-3 hours. The shelf life of cooked potatoes can increase or decrease depending on other ingredients.
Once cooked (whole or cut) potatoes can be stored in water (with or without vinegar) without becoming discolored or mushy. But, water storage isn't necessary. Refrigerate the boiled potatoes in a sealed container and use within a couple of days.
Cooked potatoes and other cooked vegetables can be safely kept in the refrigerator 3 to 4 days.
To ensure the quality of your leftover baked potato, store it properly. Let your potato cool completely (unwrap it if baked in foil). Place potatoes in a metal or glass pan, cover them with plastic wrap or aluminum foil, and refrigerate them.
The last thing you want to do is store the potatoes while they're still hot. As a matter of fact, that goes for all foods. When you store hot food, the salmonella bacteria has better chances of spoiling it. So, you have to wait until the food is at room temperature or slightly warmer before putting it in the fridge.
Peeled potatoes left out by themselves at room temperature, on a refrigerator shelf or wrapped in foil or plastic wrap will still get dark overnight, so submerge them in a bowl of water, cover and refrigerate. Cubed peeled potatoes can sit in water overnight, but they need to be refrigerated.
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.
How Long Peeled and Cut Potatoes Last in Water. You should store peeled and cut potatoes in water for 24 hours to ensure the quality of your final product. "If you drain the potatoes and notice they are turning brown, that they've started getting soft, or if they are slimy you should discard them," says Brigman.
Do cooked potatoes go brown? No. Once the starch is cooked, the potato won't go brown even if it is exposed to air for a while. If you have lots of potatoes that need to be used up, the best option is to peel and cube them, then cook them and freeze them in portions.
How Far in Advance Can You Peel and Slice Potatoes? If you'll be cooking the potatoes in the next few hours, you can leave them submerged in water at room temperature, Tiess says. If it will be longer than a few hours, place them in the refrigerator.
Here's the deal on those spuds. When cooked potatoes are left out at room temperature or warmed up for a second time, they can take a toxic turn for the worst. Why? Warm temperatures promote the growth of the rare bacteria, botulism, that is commonly found in potatoes.
When stored in a cool, dark place, (warmer than the fridge but colder than the average temperature of your kitchen) whole, uncooked potatoes can last up to two months. At room temperature, on the counter, for example, potatoes will last up to two weeks.
Sad news for spud lovers: reheating leftover potatoes could make you ill. As the Independent reported, the issue with reheating potatoes isn't actually the process of warming them in the microwave or oven. If cooked potatoes are left to cool at room temperature for too long, the bacteria that causes botulism may form.
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.
Potatoes are best kept around 45 to 50 degrees, which means they shouldn't be stored in the fridge or freezer. The best place to store them for maximum shelf life is a cool basement or garage—as long as it's dry.
However, newer research shows that the potato, when cooled down, is actually a cheap and nutritious superfood, able to help weight loss, improve mood and boost the immune system. Let me explain. When potatoes are cooked through, then left to cool down, they form a firm texture.
Store in the refrigerator at around 40°F (5°C)
Your final step in ensuring that your cooked potatoes would not go bad overnight is to store them in a refrigerator with a temperature not higher than 40°F (5°C).
The whole process is simple: peel them, leave them whole or dice them if you want, fill a bowl with cold water, submerge the potatoes and store in the fridge overnight. While this trick can be quite handy, it will only work for about 24 hours, so we would recommend to not prep your potatoes too far in advance.
For longer storage, you can store the potatoes (without water) in an airtight container in the refrigerator for a few days. For long-term storage, allow the boiled potatoes to cool down and air dry, then place in a plastic freezer bag, removing as much excess air as you can, and store in the freezer.
