How long can mashed potatoes be left out of the refrigerator?

According to USDA guidelines and food safety best practices, mashed potatoes should not be left out of the refrigerator for more than 2 hours at room temperature.

After cooking mashed potatoes, it's essential to cool and refrigerate them promptly. This helps prevent the growth of harmful bacteria that can cause foodborne illnesses. You can store them, covered or in an airtight container, in the refrigerator for up to 3 to 4 days. When ready to consume, reheat the mashed potatoes until steaming hot (internal temperature of 165°F or higher).

For longer storage, you can opt to freeze the mashed potatoes. Place the cooled and covered mashed potatoes in freezer-safe containers or sealable freezer bags. They can be stored in the freezer for up to 2 to 3 months, ensuring their safety and quality. To use, thaw the frozen mashed potatoes in the refrigerator or cold water before reheating them thoroughly.

It is always recommended to follow proper food safety guidelines and refrigerate perishable foods promptly to prevent bacterial growth and ensure your health and safety when consuming mashed potatoes.
