Can you eat left over baked potatoes out if not in aluminum foil?

It is not recommended to eat leftover baked potatoes that have been left out, whether or not they were wrapped in aluminum foil. Leaving cooked potatoes at room temperature creates an ideal environment for the growth of harmful bacteria, which can cause foodborne illness.

According to the United States Department of Agriculture (USDA), leftover baked potatoes should be refrigerated within two hours of cooking, and consumed within three to four days. Always reheat cooked potatoes to an internal temperature of 165°F (74°C) before eating.

Storing baked potatoes in aluminum foil does not extend their shelf life or make them safer to eat. Instead, it helps to maintain their heat and moisture when storing in the refrigerator, but they should still be properly cooled and refrigerated within the recommended time frame.

For safety, always follow recommended food handling guidelines to minimize the risk of foodborne illness.
