How To Freeze Mashed Potatoes ?

  • Prepare mashed potatoes according to your favorite recipe. It is up to you how you like this dish, so cook it the way you like it most.
  • Thoroughly cool the prepared meal. If you want to cool it down faster, consider putting it in a slightly cooler place (e.g. in the pantry).

Method 1 (Less Work Required)

This method is simple – you need to put mashed potatoes in freezer bags, deflate all of the air in the bag, and seal the bag. You can also use zippered pouches, which is probably the easiest method.

If you choose to use small freezer bags, preferably serving size, that’s even better. This way, you can easily thaw and reheat as much mashed potatoes as you need in one go.

And, instead of freezer bags, you can use airtight containers. If so, keep in mind that the container should be almost full (the more air in it, the worse the freezer burn).

Method 2 (A Little More Work)

The first thing you need to do is line a baking sheet with parchment paper. Then measure out even portions of mashed potatoes with a large scoop and transfer them to the baking sheet.

Then, place the baking sheet in the freezer for at least a couple of hours (e.g. overnight). Make sure the portions are thoroughly frozen before taking them out of the freezer.

Now you have to transfer the frozen potato puree balls into a freezer bag and put them back in the freezer. Freezing the mashed potatoes in small portions will only allow you to defrost as much of it as you need.

Thawing And Reheating Frozen Mashed Potatoes

You can defrost and reheat frozen mashed potatoes in the microwave or oven. If you want, you can thaw it a little more before heating it by placing it in the refrigerator for a couple of hours.

Use around 50% of the power of your appliance when heating, and don’t forget to stir the dish from time to time.

For example, if you are using a microwave, microwave it for a minute, stir, microwave it for a minute, and so on. Then, heat it until it is done.

Things To Remember

  • Properly label each bag of mashed potatoes. Remember to write the name of the dish, the amount and the date there.
  • Add a little sour cream when heating (if defrosted, mashed potatoes are too watery). This will help achieve the right texture when the dish is ready.
  • Although you can keep mashed potatoes in the freezer for a long time, be careful. Storage for more than 6 to 8 months is not recommended for reasons of quality.

Final Words

How long do mashed potatoes last in the fridge? As you know by now, you can freeze mashed potatoes, and it is pretty easy to do.
