How To Keep Mashed Potatoes Warm

Mashed potatoes are a great side dish with many meals. It can be a struggle to keep them warm because they cool off so fast.

I am going to go over a few easy ways to keep mashed potatoes warm when serving them so that you aren’t serving cold food.

These suggestions also fall under how to reheat mashed potatoes!

Easy ways to keep your mashed potatoes warm and reheat

It can be annoying when you cook up a nice hot meal only for it to be cold by the time the plate hits the table. Or worse, your side gets cold before the main course is finished. Mashed potatoes are big offenders when it comes to cooling off fast.

You want to avoid having to reheat your mashed potatoes as they will dry out. It is important to keep them warm rather than reheating them. I am going to give you a few of my tricks to save you from serving cold food again.

In a crockpot

Using a crockpot to keep your mashed potatoes warm is a great way method to use if you are not ready to serve them. Simply prepare your mashed potatoes as you wish and then place them in your crockpot in a warm or low setting.

Keeping the setting warm, your mashed potatoes will not get cold. This way you can prepare them ahead of time and keep them from getting cold or you use this as a way to keep them warm while you’re finishing up the rest of your dish.

If you are having a dinner party, hosting a buffet, or maybe you were asked to make the mashed potatoes for Thanksgiving dinner at your In-laws, placing your mashed potatoes in a crockpot is a great way to keep them warm.

There are also some ways to add flavor to mashed potatoes.

In the oven

Much like keeping mashed potatoes warm in a crockpot, you can also use your oven. Using an oven-safe dish with a cover or tin foil over the top, place your mashed potatoes in the oven set at 300°F.

It is important to have a cover on them to keep as much moisture in as possible and prevent them from drying out.

This will keep them warm until you are ready to serve them. The low temperature will keep the mashed potatoes warm without continuing to cook them or dry them out. Note that the longer you leave them in the oven the more they dry out though.

I recommend this method to keep mashed potatoes warm for no more than 45 minutes. If you are going to need them kept warm longer then I recommend using a crockpot.

Either way, you may need to add a little milk or cream and stir them up to bring back some of the moisture.

Cover with aluminum foil

If you are getting really close to serving or maybe you are leaving your mashed potatoes out for anyone that might want seconds, simply cover the dish with aluminum foil to help retain the heat while you are eating.

This method is best if you plan on serving mashed potatoes within 10-15 minutes otherwise the heat will eventually seep out of the foil and start to cool off.

Serve on a warmed plate

Serving food on a cold plate will suck the heat right out of your food the second that it hits the plate. If you warm the plates that you are going to serve the food on it will help keep the food warm.

Look at the bottom of your dishes and make sure that they are oven or microwave-safe before you use this method. If your dishes aren’t marked then I do not recommend doing this.

Place the plates in a warming drawer or if you aren’t fancy like me, then you can place them into a warm oven or microwave for a few minutes. This way when you place hot food onto the plate it is already warm which will keep your food warm also.

When warming plates in the oven you want to heat the oven to 140°F-175°F and leave them in for about 15 minutes. Use oven mitts to remove them from the oven.

You can also use the microwave to heat your plates by stacking them in the microwave on high for 2 minutes with a glass of water with a cup or so of water on top.

I recommend using oven mitts when removing them from the microwave or oven as you could get burned. Also, placemats aren’t a bad idea to protect your table if they are still hot.

If you have them called out of the fridge then I have an entirely different process with reheating mashed potatoes.
