To reheat Main Street mashed potatoes, the best methods are the microwave (quick, stir often with extra liquid/butter) or the oven (for larger batches, bake covered at 350°F). For creamy results, add a splash of warm milk or cream and butter during reheating, and stir in more as needed to restore moisture, especially for stovetop or microwave methods, which can dry them out.
Restaurants prepare the potatoes ahead by boiling and mashing just the potato, then just before serving, it is mixed into boiling cream (or milk or even broth or a combination thereof) to reheat it and make it nice and creamy.
Stove Top: 1. Small amounts can be heated on the range top by placing mashed potatoes in a heavy saucepan over medium heat, stirring constantly, until hot. 2. You may add a small amount of milk or water to aid in heating.
The easiest way to reheat mashed potatoes is in the microwave. Reheat them on high, stirring every 30 seconds, until heated through. If needed, stir in extra milk or butter, 1 tablespoon at a time. You can also reheat mashed potatoes in a 350° oven. Let the mashed potatoes sit on the counter while the oven preheats.
If you're in a hurry or have smaller quantities, reheating on the stovetop in a Dutch oven with frequent stirring works well. Regardless of the method, consider adding a bit of butter, milk, or cream while reheating to enhance the texture and flavor.
You can cook and mash the potatoes up to two days ahead of time, and reheat them in the oven when you're ready to eat.
For a baked potato, reheating it in the oven will give the best results, maintaining a fluffy inside and crispy skin. Wrap it in foil to prevent drying out. If you're short on time, the microwave can work, but the potato might lose some of its texture—microwave in short bursts to avoid overcooking.
Cool completely, store in vac pack bags. Reheat in waterbath, transfer to pan, warm cream butter up, beat into mash with Maurice. Pulse in robocoupe very slightly. If you do this too much it will just split and ruin it.

"Hold your mashed potatoes in a bain-marie, or water bath, with a lid on top [and] they stay for hours—days really," Ray said in an interview with Allrecipes while promoting her partnership with Home Chef. The method is oh-so-simple.
The Oven Is the Best Way to Reheat Mashed Potatoes
Though you can totally put leftover mashed potatoes in the microwave or on the stove, the oven is our recommended method for the creamiest, pillowiest mashed potatoes.
OVEN: Bake at 350 degrees F until warmed through, about 20-25 minutes OR bake potatoes from frozen for about 1 hour. MICROWAVE: Place thawed potatoes on a microwave- safe plate. Microwave, uncovered, on high power for 2-3 minutes or until heated through.
Slow cooker method
Just as you can make mashed potatoes in a slow cooker, you can reheat them that way, too. Simply add them into your machine, cover, and set to low. Warm through for two to three hours, stirring occasionally and adding milk, cream, or butter to add moisture if necessary.
The Restaurant-Style Revive
Instead, the mashed potatoes are prepped before service, then finished as needed. The key is to leave the cream out until the last minute, then heat it up and use it to bring the potatoes back to life.
Regular oven or toaster oven
Reheating in the oven is a great way to ensure you keep the crispy skin and don't end up with soggy potatoes. Method: Preheat oven to 400. Arrange cooked potatoes on a baking sheet in a single layer (if desired, line with parchment paper). Cover pan with aluminum foil and place in hot oven.
If you have time, thaw the potatoes in the refrigerator the day before reheating, otherwise reheat from the freezer using: • Stovetop: Reheat in a large pot, over low to medium heat, stirring occasionally. Oven: Reheat the potatoes, thawed or straight from the freezer, in a covered dish at 350°F for about 30 minutes.
You might be able to salvage them the next day by heating them up with additional butter or cream, but they'll probably never return to their former glory. Instead, here are a few creative ways to use up leftover mashed potatoes that won't leave you wishing it was yesterday.
In the Microwave
To prevent that from happening, cut the potato in half and cover each half with a damp paper towel. Place the potato in a microwave-safe dish and heat for two to three minutes, or until the potato is heated through.
It might come as a surprise to learn that mashed potatoes can actually be made a few days ahead of serving. Not only is this a welcome time saver during busy holidays such as Thanksgiving, but your spuds will turn out creamier and fluffier when prepared in advance.
