How to Freeze Mashed Potatoes

First, you need to make your mash. Normally, we wouldn’t include a recipe or recommendation, but the recipe is vital for freezing it. You want plenty of fat and cream to help the potatoes freeze. Normally, potatoes don’t freeze that well.

That’s why we’d highly recommend turning to James Martin’s mash recipe. He notoriously doesn’t skimp on the fat. With 1kg of potatoes, he uses 200ml of double cream and 100g of butter. Creamy, smooth mash that will freeze perfectly – just don’t forget to season with salt and pepper.

Now you’ve made the perfect freezable mashed potatoes let’s look at how you actually freeze them:

There are two approaches when it comes to freezing your mash:

How to Freeze Mashed Potato Portions

If you don’t mind taking a bit of time over freezing your mash, this is the method to use. It’s a little more time-consuming but worth the effort in the longer run:

  1. Cool
    Once you’ve given your mash time to cool, line a baking tray with greaseproof paper.
  2. Scoop onto Baking Tray
    Scoop your mash onto the tray in even-sized portions. You can use an ice cream scoop here to make your life easier.
  3. Flash Freeze
    Once portioned out, place the tray in the freezer for betwee 30 minutes and several hours to allow your mash portions to freeze.
  4. Final Freeze
    Now that they’re frozen remove the tray, remove the individual portions and place them into a bad then return to the freezer.

How to Freeze Mashed Potato in Bulk

If you’re pushed for time and would prefer to freeze it in one mass then go with this method:

  1. Cool
    This is a far easier approach. Once you’ve made your mash, you need to allow it to cool to room temperature.
  2. Bag Up
    Transfer the mash to a freezer-safe bag and then squeeze out as much of the air as possible.
  3. Freeze
    Place it in the freezer, and you’re all done.

That was easier! Right?

3 Tips for Freezing Mashed Potatoes

Now you know how to freeze it, we’ve got our 5 top tips which we strongly recommend following when freezing mash to have the best results:

Use Fat (And Lots of It!)
This is no time for a diet. Fatty, creamy, rich mashed potatoes will freeze better than other mash so don’t skimp on the cream and butter when making them for the freezer.

No Need to Thaw Overnight
Mash is one of those great dishes that you can freeze that doesn’t need to thaw overnight in the fridge. Instead, you can use it directly from the freezer.

Consider Freezing in Portions
Freezing anything in portions makes it far easier to avoid wasting it further down the line. It takes a little extra time to do but freezing mashed potatoes in portions is a must!

How Long Can You Freeze Mashed Potatoes?

Mashed potatoes will last for a good 6 months in the freezer. As always, you must label your potatoes with a use-by date, so you don’t let all your effort go to waste.

This is also applicable for dishes that you’ve frozen with a mash topping or filling such as shepherd’s pie or fish cakes.

You Can Freeze Mashed Potatoes for up to 6 Months

How Do You Defrost Mashed Potatoes?

When it comes to defrosting your mash, you have a couple of options, and neither requires much time.

On the Hob: You can reheat the mash straight from the freezer on the hob. Just place your mash in a pot over low to medium heat (the slower, the better), stirring occasionally. It will begin to thaw and then turn into your creamy mash.

Check the seasoning and add in a knob or two of butter for good measure.

Microwave: Place your frozen mash into a baking dish that’s suitable for the microwave and cover. Turn the microwave on for 5 minutes on low power then stir it. Continue to heat in 2 to 3-minute intervals until the mash is hot through and creamy.

Can You Refreeze Mashed Potatoes?

We wouldn’t recommend refreezing mashed potatoes if you plan on trying to use them again as mash on its own. You’ll find it can become quite grainy, which won’t be enjoyable.

The only exception to this is if you have used the mashed potatoes for a pie topping. For example, you could freeze a portion of mashed potato, defrost it, spread it over the top of a pie, cook it and then freeze that pie.

Do Mashed Potatoes Freeze Well?

Fresh will nearly always be better. But, if you plan on freezing mashed potatoes then throw the diet book out the window, forget about your calorie count and load your mash with plenty of cream and butter. It will help the texture and will taste gorgeous too.

Can You Freeze Mashed Sweet Potatoes?
