When time is limited and mashed potatoes are a "must have" on the menu (which is always), keep the prepared potatoes warm by placing them in a heat-resistant bowl, covering, and setting it over a pot of simmering water. The potatoes should still be tasty 2 to 3 hours later.
The ideal temperature to keep mash potatoes warm is 300 degrees Fahrenheit, especially when you're using an oven or crock pot. But, to keep it warm without overcooking, make sure to put it in a pan or bowl covered with foil before placing it inside the oven.
Put the lid on your mashed potato pot and gently place the pot inside the simmering water bath. Leave the stove on and allow the water to simmer for as long as you need it to keep your potatoes warm. Not only will the water bath keep your potatoes warm, but it will also keep them light and fluffy.
Probably the simplest is to place the mashed potatoes in a heat-proof bowl over a pot of simmering water. You can cover the bowl with foil, or use a lid that fits over the bowl. Make sure the water doesn't burn dry, and never gets above a simmer—and that's it.
Hold Potatoes on "Warm": Mashed potatoes can be held on the "warm" setting of your slow cooker for up to two hours or so without noticeable loss of flavor or texture.
Make-ahead mashed potatoes are a great option for the holidays. You can do nearly everything — boil, peel, and mash; stir in milk and salt — up to two days ahead. Before serving, reheat. Adding butter at the last minute makes them taste freshly mashed.
Your other option would be placing the prepared mashed potatoes in a buttered, oven-safe dish (covered in aluminum foil) and sliding it into a 275- to 300-degree oven. I wouldn't recommend trying to keep your spuds warm for more than 30-40 minutes using this method or you risk drying them out.
You can reheat these make-ahead mashed potatoes either in the oven or the microwave. To reheat in the oven, pour melted butter on top of the potatoes and bake for 40 to 45 minutes at 350°F or until they are hot all the way through. Place aluminum foil over the top to prevent them from browning.
Mashed potatoes can sit out for two hours at room temperature. Any longer than that, they can enter the “danger zone,” which are unsafe temperatures that promote the growth of bacteria. If temperatures go above 90 °F, mashed potatoes can only sit out for one hour.
Keep warm for up to 4 hours, stirring once an hour. Stir before serving. The mashed potatoes will stay warm and creamy.
Reheat on the Stovetop
She says to store them in a heatproof bowl after cooking; when it's time to warm them up, place the bowl over a pot of simmering water. Add an extra splash of cream or milk, and another pat of butter to ensure the mashed potatoes don't dry out.
Too much heat and you'll dry your potatoes out. Too much moisture and they'll turn to glue. The directions below, which are similar to reheating stuffing in the microwave, work well in most situations. But they will need to be adapted based on your microwave power and how much mashed potatoes you're reheating at once.
You shouldn't let mashed potatoes sit for more than 2 hours at room temperature. What is this? However, if you've added dairy products like butter, sour cream, or cream cheese, you should store the potatoes as soon as possible. These add-ins make the potatoes less stable and more likely to breed bacteria quickly.
You want to be able to eat your potato without worrying if you are going to get food poisoning or botulism. Here's how you can ensure that your baked potatoes are safe to eat. DON'T let your potato sit out in the open at room temperature for over four hours regardless of whether or not it is wrapped in aluminum foil.
Transfer the mashed potatoes to a large microwave-safe bowl and cover tightly with plastic wrap. Refrigerate for up to 2 days. To reheat, poke lots of holes in the plastic wrap with the tip of a knife and microwave at medium-high (75 percent) power for about 14 minutes.
Warming ovens, or holding cabinets, are found in most professional restaurant kitchens. This type of commercial food warmer equipment plays an integral role in keeping extra food products warm until it's ready to be moved to a steam table or a customer's plate.
Peel potatoes using a vegetable peeler. It's best to leave them whole, but you can go ahead and cube or dice them if you want — just don't slice them too thin. Fill a bowl with cool water, submerge the potatoes, then cover with plastic wrap. Store in the refrigerator overnight.
You can prepare the spuds up to 24 hours before you need to cook with them. Then, on the evening you're planning to serve them, you can make creamy potatoes at the drop of the hat. Start by scrubbing potatoes under cool running water to remove dirt; dice, slice, or chop as directed in recipe.
Tips for the Best Mashed Potatoes
Start cooking the potatoes in cold water: This ensures that the potatoes cook evenly. Otherwise, if you start with hot or boiling water, the outsides of the potatoes cook and soften while the middles are still hard and crunchy.
Tip #4: Never try to mash up cold potatoes. It has to do with some chemical-y thing with the starch. If your potatoes go cold, heat them up again (in warm water, a microwave) and then try to mash them.
Excess water is one way to ruin a perfect mash. A simple way to get around that problem is to fully drain your potatoes and place them back into the hot pot. The heat from the pot will make any excess water evaporate and prevent your mash from getting soupy.
Place mashed potatoes in a heat-safe bowl over a pot of water to reheat and keep warm on the stove. Reheat the potatoes in a method you choose and keep hot on an electric warming tray or a heating pad covered with a pretty towel.
A: Your best bet is to use bread warmers. Here is what I recommend… to have a hot potato that is dry and fluffy, as well as being able to store the potato in foil for an extended serving time, bake the potatoes at 400 degrees F in a convection oven without any foil.
Your Oven. Some ovens actually will have a "warm" setting, which is usually 170 to 200 F, or a warming drawer, which is meant to keep foods at a level, warm temperature. If your oven has neither, set it to 200 to 250 F.
Usually the local health department determines how long you can hold them, which is typically no more than two hours, but I recommend no more than 45 minutes to keep the integrity of the potato, as the base will turn dark brown and outer skin will wrinkle.
