These are the best and easiest ways to reheat mashed potatoes! Whether you’re prepping your potatoes ahead of time, or simply looking to enjoy leftovers, give these methods a try for perfectly smooth and hot mashed potatoes.
What Makes These Methods So Good
- Each method involves additional milk and butter, making them extra rich and delicious! These reheated mashed potatoes are arguably even more delicious than the fresh kind.
- They’re not dry at all! I’m sure if you’ve tried to reheat mashed potatoes before, you’ve found they turn out unappetizingly dry. Well these methods introduce and lock in as much moisture to the potatoes as possibly, making them extra soft and creamy!
- They’re all equally as quick and easy! Each reheat method involves only two steps, helping you get warm mashed potatoes on the dinner table in no time.
How to Reheat Leftover Mashed Potatoes
In the microwave: I’m sure we’ve all tried this method before, but trust me, you’ve never tried it quite like this. First, you’ll want to heat your potatoes in the microwave set at half power. This will avoid drawing out too much moisture from your mashed potatoes. Then, once warm, stir in some extra butter and milk to bring your potatoes back to life – they’ll be good as new!
In the oven: This hands-off technique requires a bit more time than the other two, but is probably my favorite. Transfer your mashed potatoes to a baking dish and cover with a couple tablespoons of butter and milk. Don’t stir anything, instead just cover the dish with foil. Then, bake it for about 25 minutes or until warm throughout. Once warm, give the potatoes a stir and trust me when I tell you they’ll taste fresh and delicious!
On the stove: Place leftover mashed potatoes in a pot with a tablespoon of butter and some milk. Warm the potatoes over low heat on the stove, being sure to give them a quick stir at least every minute. Once warm throughout, remove them from the heat and enjoy!
Tips for Success
- It is essential that you reintroduce at least some moisture to reheated mashed potatoes. Therefore, do not skimp on the additional butter or milk in these methods!
- Feel free to doctor up your mashed potatoes with extra herbs if you’d like! While reheating, you can stir in additional flavorings to switch your potatoes up however you choose.
- You can easily double up on the amounts for each method, or cut them in half based on how much leftover mashed potatoes you have. If I’m reheating a bowl for just myself, I’ll sometimes cut these methods down by a quarter of their listed amounts!
