Dehydrating Cubed Potatoes For Preparedness Food Storage

by Texas Homesteader ~ 

I always have a couple of jars of dehydrated cubed potatoes in my pantry. From a preparedness standpoint I love to have dehydrated food available.

Jars of dehydrated food aren’t dependent upon electricity to keep them preserved like when storing food in a freezer. Dehydrating cubed potatoes for the pantry, an easy way to preserve the excess! A Mother Earth News post. #TexasHomesteader

Larger Quantities Of Perishable Potatoes

D’ya ever eyeball that big honkin’ bag of potatoes, compare the price to that small overly-expensive bag of potatoes and have a hard time making the economics make sense? Yeah, me too!!

As empty nesters there are only 2 of us here these days in our household. But dang it just doesn’t make sense to pay more per pound for a smaller bag of potatoes.

Recently I acquired a large quantity of potatoes and went on a mission to cook and/or preserve them all.

Freezing Excess Potatoes

Sometimes I preserve potatoes by cooking, mashing and freezing them with nothing else added. When I’m ready for mashed potatoes I just bring them out to thaw, drain the excess water and heat the up adding salt/pepper/butter. Then BOOM! Homemade mashed potatoes.

But sometimes you need a backup for those times when the electricity might go out, such as during the Severe Winter Ice Storm we endured a few years back.

Our electricity was off for days. Everything in our freezers was in danger of being wasted.

Although I was able to salvage much of it, sadly some was wasted too. Y’all know how I hate food waste!

Dehydrated Potatoes Use Little Space

So I love the benefits of having dehydrated food in my pantry. It can be stored in small repurposed glass jars on the shelves of my pantry. No additional energy is required to store food this way.

One of our favorite ways to preserve excess potatoes is by shredding & dehydrating them to use for dehydrated hash browns and we love them this way.

But I also want to dehydrate cubed potatoes like I’d use in a stew. That gives me a little more variety in my pantry storage, bebe!

Dehydrating potatoes is super easy, but there’s one important thing you must do before successfully dehydrating them.

Keeping Dehydrated Potatoes From Turning Black

Just cutting potatoes and drying them will cause the potatoes to turn black in each spot a cut was made.

Case in point – We prefer our potatoes with the skins on. So I scrubbed several russeted potatoes and cut away every eye or deeper crevice.

Then they were partially cooked (but not cooked enough) and I put them in the refrigerator to cool overnight. This was the very ugly result.  Potatoes not cooked long enough will turn black where cut. #TexasHomesteader

Ewwwwww… not very appetizing.

To salvage them I ended up cooking them a little more, cooling them again and cutting away all the dark spots before grating them for dehydrated hash browns. So at least they weren’t wasted.

But it’s a good lesson. Before dehydrating potatoes you need to cook them about 3/4 of the way.

So I scrubbed more potatoes and then pricked the skin in several places on each potato. Then I stacked them tightly in a black enameled pan.

Cooking Potatoes With FREE Solar Energy

You can cook your potatoes using your favorite method whether oven or microwave. But by using my *solar oven outside I’m able to use FREE solar energy to cook my potatoes. 

I covered the pot with the lid and placed it into my solar oven. After closing & latching the oven door I pointed the reflectors at the sun. The oven was adjusted about every hour to help it track the sun and keep interior temps consistent.

I removed the potatoes from the solar oven when I began to see steam collecting on the glass door about 3 hours later. Your time could vary based on your cooking method & the size of your potatoes.

You want the potatoes to be almost fully cooked but still firm, about 3/4 of the way. That way they’re cooked enough not to turn black when cut but still firm enough to cut easily.

I brought the cooked potatoes into the house and spread them on the counter to cool. Then I placed them in the refrigerator overnight to chill.

Dehydrating Cubed Potatoes

The next morning I diced the cold potatoes into approximately 1/4″ – 1/2″ cubes. I don’t want big honkin’ cubes. Not only will larger cubes take more time to dehydrate but also more time to rehydrate in the stew pot as well. 

After they were cut I spread them evenly on my *Excalibur Dehydrator trays. Then I set the temperature to 125 degrees.

My diced potatoes took about 10 hours to dry but drying time is dependent on how dense (ie: cooked) the potato is as well as the uniformity and size of the pieces. 

It’s also dependent upon how often you rotate the trays, how evenly you’ve spread them out and even the humidity in your area.

But you want your finished dehydrated potatoes to be hard and dry. Even a smidgen of moisture left in just 1 tiny piece of potato sealed in a jar will ruin the entire batch!

Extra Step To Assure No Moisture Remains

So I placed my dehydrated potato pieces into a large open-top container and left them on our kitchen counter for a couple of days. I mixed the contents several times to expose all surfaces to the air for further evaporation.

When I was certain no moisture remained I poured my dehydrated potatoes into a clean, dry repurposed jar. Then I sealed it up, added a label and placed it in my pantry.

Rehydrating Dehydrated Cubed Potatoes

When I want to use some of the dehydrated cubed potatoes I’ll simply drop a handful into my brothy Endless Soup as it simmers.

Those potato cubes will rehydrate and finish cooking right there in the soup pot!

To rehydrate potatoes by themselves I place a handful of dehydrated cubed potatoes in a metal bowl. Then I pour just enough boiling water to cover them and then place a cover on the bowl.

Depending upon the size of the potato cubes I’ll allow them to rehydrate for about 45 minutes. Then I can finish their cooking time on stovetop or oven along with my recipe.

You can see how the potatoes rehydrate compared to their dehydrated counterparts in the photo above. 

So go ahead, next time buy the BIG bag of potatoes and dehydrate them!

    Found your blog looking for how to dehydrate pumpkin and have been linkhopping ever since. 🙂 You mention your “endless” soup several times, but the link is dead. Can you restore the page it was on? I’m intrigued. Thanks!

      (blushes) I *may* have jumped the gun by linking to that post already, Maria. The Endless Soup post is due to be published tomorrow. (why yes there’s egg on my face, why do you ask?? LOL) BUT, if you’re a subscriber to my blog you’ll get an email first thing in the morning with the link to that post in it! Endless soup is one of the ways I always have hot, nutritious lunches for RancherMan & myself when just grabbing a sandwich just won’t do. AND it keeps us in healthy heat-n-eat lunches for the better part of a week. Oh, and reduces food waste too. You’ll love it! ~TxH~

    Enjoyed the article on dehydrating potatoes. Will this work with sweet potatoes and butternut squash? Recently I dried the hot peppers I grew this past summer. The peppers where in the dehydrator for about 12 hours, however, they did not seem to be crisp. In order to be sure that there was no moisture left in them, I spread them on lined baking trays, put the trays in the oven, with the light on, and left them there overnight. The next morning, they were crispy and flaky. I turned off the light and left them in the oven with the door ajar. A few hours later, they were cool, and I stored them in glass canning jars. I grew several different varieties of peppers, and they smell delicious.

      It will absolutely work with sweet potatoes. Actually I daresay there’s precious little produce you can’t dehydrate for pantry storage – even something as moisture-heavy as watermelon! When I’m dehydrating potatoes I don’t try to get them crisp, just dry. The various peppers I’ve always dehydrated weren’t crisp either, just dry. But I was only using my peppers to rehydrate and use as an ingredient in recipes. Once I was dehydrating cinnamon apples and I actually wanted them crisp. But dehydrated they were dry but not crisp. So after they were dehydrated I placed them in a low-temperature oven with the door ajar just long enough to crisp them up. But unless you’re specifically after the crisp texture (such as with my dry apples) you just need to dehydrate the food until all moisture is gone before storing. I’m assuming you wanted your peppers crisp to be able to grind them into a powder. I’m jealous of your jar of pepper – so many delightful ways to flavor food with home-grown dry peppers. Enjoy the fruits of your labor, girlie. You’ve earned it! (and if feels pretty good, doesn’t it??) ~TxH~

      It works beautifully Angelina, and since they’re dehydrated it takes no additional energy to store them in the pantry. Gotta love it! ~TxH~

    I do the same as Lana, only I boil my potatoes for 3-5 minutes. I do the same for making French Fries, steak fries, etc.
    I think best tasting fried potatoes is to fry them in bacon grease. I save all my bacon fat, store in container and put in freezer for later use.

      I’d like to try making french fries for the freezer. And you’re right Colleen, bacon grease is mandatory! ~TxH~

    My dehydrator escaped my house when one of my kids moved out and then she gave it to her roommate! Kids! I peel and cube and boil for 8-10 minutes. Then I pour them out onto a baking sheet to cool. After they are cool I freeze them in portions for one meal. Browned up in some fat in a skillet, they are delicious and you cannot tell at all that they have been frozen.

      I’m *SO* gonna try this Lana. I’ve not been successful with freezing potatoes other than mashed potatoes (which I’ve done often) I’d love to have frying potatoes as close as my freezer! ~TxH~
