If you’re a potato lover, chances are you sometimes cook more than what you and your guests can eat.
In those cases, knowing how to reheat leftover potatoes can be a real lifesaver – especially if you don’t want to waste food.
Roasted potatoes are a classic side dish that, when reheated correctly, can still be crispy and delicious.
In this post, we’ll explain how to reheat roasted potatoes in eight different ways using an oven, microwave, skillet, searing, air fryer, toaster oven, broiler and slow cooker.
But first things first:
Is It Safe To Reheat Leftover Potatoes?
While leftovers are typically safe to eat when reheated properly (within four days of cooking), there’s one exception: Potatoes.
If left at room temperature for too long after they’ve been cooked or improperly refrigerated or reheated potatoes can cause botulism – a rare but dangerous type of food poisoning.
To reduce the chances of getting sick from reheated roasted potatoes:
- Always store potatoes in the refrigerator within two hours after they’ve been cooked.
- Never leave potatoes at room temperature for more than two hours.
- Reheat prepared foods like roasted potatoes to an internal temperature of 165 degrees Fahrenheit (74 Celsius)
