This is especially true with leftover mashed potatoes after family dinners, holiday meals and weekend get-togethers. Okay, freshly made mashed potatoes are creamy and smooth and dreamy, but the refrigerator leftovers get thick and dry or lumpy. Even better, once you understand how to reheat mashed potatoes correctly you can make them smooth and tasty again.
Whether your goal is to be reheating one portion for lunch or reheating a whole tray from the Thanksgiving leftovers, the right way makes all the difference. Honor those leftovers with a little butter, milk or cream and some very gentle heat — your potatoes could taste almost like fresh again.
This guide includes the best reheating methods, common pitfalls to avoid, storage tips and insider information so you can have creamy mashed potatoes every time.
Why Mashed Potatoes Become Dry After Refrigeration
Nothing about storing mashed potatoes is easy because they fail to hold their texture.
Moisture Is Lost
The same would happen when potatoes have cooled, which turned drier and makes it thicker rather than creamy.
Butter Hardens
Cold masher root solidifies butter into a cold little ball; mashed potatoes feel harder than it should.
Starch Firms Up
The potato starch continues to absorb moisture while in storage for a denser texture.
Fortunately, these changes can be undone quite easily with the appropriate reheating technique.
Best Ways to Reheat Mashed Potatoes
The manner in which you would like reheating will depend entirely on how much you’re reheating!
Microwave Method
The microwave remains the fastest option for single or double portions.
Steps
Add the mashed potatoes to a microwave-safe bowl.
Stir in 1 to 2 Tablespoons of milk or heavy cream.
Add a small piece of butter.
Loosely cover with a microwave-safe lid, or damp paper towel; they get too dry.
Microwave for 1 minute.
Stir well.
Heat in 30-second increments until heated through.
This process typically takes around 2 to 3 minutes.
Stovetop Method
Stovetop is preferred by many home cooks as it gives the creamiest texture.
Steps
Put the mashed potatoes on a pot.
Add some milk, cream, or chicken stock

A slow cooker works magic to keep mashed potatoes warm until serving time.

Real-World Example
Jessica — from Ohio, of course — made some homemade mashed potatoes for her Thanksgiving dinner. Post the festival she put the remnants in a sealed jar and kept it in chilled surroundings overnight.
The following evening, she heated the potatoes in a pan on the stovetop with a little whole milk and one tablespoon of butter over low heat. She stirred them occasionally until they were smooth and creamy again.
It was reported that the family thought the mashed potatoes were nearly as fresh as they had been on Thanksgiving Day. She always makes use of delicate heat with a bit bit of moisture to keep away from dry or gummy leftovers.
