Baked potatoes can last for 5-7 days in the refrigerator and 6-8 months in the freezer. Never leave your baked potatoes for more than four hours at room temperature because it increases the risk of botulinum bacteria contamination.
Although potatoes are generally OK to eat the next day, there are two circumstances in which they can become problematic when reheated. The first is when potatoes aren’t stored in the fridge after cooking, which can give rise to dangerous bacteria Clostridium botulinum.
Hands down, the best way to reheat a baked potato is in the oven. This method helps keep the potatoes from drying out. Preheat the oven to 350° F and take the potatoes out of the fridge so they reach room temperature. Bake for 15-20 minutes, or until the potato is heated through.
You can lower the temp to 400 degrees F for 50-60 minutes in a convection oven, which cooks a little more evenly and consistently. Many recipes call for 375 degrees, which is too low. The potato is fully cooked when the thermometer shows 210 degrees F, when placed halfway into the middle of the spud, half way down.
DO serve potatoes immediately after baking them or store them in the refrigerator to keep your potato at a safe temperature. If you use aluminum foil, remove the foil directly after baking to prevent botulinum bacteria from growing. DON’T place a baked potato in the refrigerator with the aluminum foil still on it.
Cooked potatoes can be stored in the refrigerator for up to four days.
At room temperature, potatoes will last up to two weeks.
That said, the potato is the most common cause of solanine poisoning in humans. If you eat enough of the green stuff, it can cause vomiting, diarrhea, headaches, paralysis of the central nervous system (as evidenced by the incident above) but in some rare cases the poisoning can cause coma—even death.
Potatoes should be kept somewhere cool and dry but not in the fridge. This is because putting potatoes in the fridge can increase the amount of sugar they contain, this could lead to higher acrylamide levels when the potatoes are roasted, baked or fried at high temperatures.
How to Reheat a Baked Potato in the Oven Preheat the oven to 350 degrees Fahrenheit. Place the baked potato on the oven rack directly to heat (this applies to whole potatoes ). Leave the baked potato in the oven for about 20 minutes. Take it out of the oven, let it cool, and enjoy.
Do store the baked potato immediately after being cooked, or place the potato in the fridge immediately to keep it at a safe temperature. If you have used aluminum foil to bake the potato, make sure to remove it before placing the potato in the fridge.
How to Reheat Twice – Baked Potatoes in the OVEN Preheat your oven to 400 degrees F. Place the potatoes on a lightly greased baking sheet. Bake for 20-25 minutes or until completely heated through.
In order to shatter the starches of the baked potato into fluffy flakes, the internal temperature of the potato must reach 210 degrees Fahrenheit. To achieve this explosion of starch grains, an oven heated to 425 degrees Fahrenheit works best.
At 200 degrees the outer edge was light and fluffy, while the core was just tender, but at 205 degrees the whites of the potatoes were at their best: fluffy from edge to center. Lesson learned: Even the fluffiest baked potatoes can be ruined if they’re not cut open immediately after baking.
Do not overcook potatoes as the insides will be dry, so it’s important to be vigilant. The higher the oven temperature, the shorter the cooking time will be and the crustier the skin. Larger potatoes will take longer to bake.
