Now, you might be wondering, what's the magic number when it comes to leaving mashed potatoes out? Well, the general rule of thumb is to keep them refrigerated within two hours of cooking, or one hour if the room temperature is above 90°F (32°C). But, let's be real, who's counting?
In all seriousness, food safety is no joke, and it's always better to err on the side of caution. So, if you're planning to leave your mashed potatoes out for an extended period, make sure to keep them at a safe temperature - below 40°F (4°C) or above 140°F (60°C). That way, you can enjoy your spuds without worrying about any unwelcome guests!
