How To Dehydrate Potatoes Efficiently?

As you now know the different forms of potatoes, let’s focus on the main topic of discussion – how to dehydrate potatoes easily at your home. Here, the main component that we will be discussing is the dehydrator. There are different ways in which you can enhance the taste of the dried vegetable easily using this device. The rest methods will describe how you can dry the potatoes without the use of a dehydrator. So, let’s find out!

How To Dry Potatoes In A Dehydrator?

A dehydrator is a special kind of machine that comes in different shapes and sizes. The best thing about getting a dehydrator is that you can dry almost anything, starting from juicy vegetables to herbs and even meat. This appliance comes with different drying settings which will allow you to dry the items under different conditions. Also, they have multiple trays which will help you to dry a bulk volume rather than a few slices like you do with the microwave oven or the regular ovens. So, let’s see how to dehydrate potatoes using this amazing device in your kitchen!

Drying Fresh Potatoes – Since fresh potatoes are a rich source of vitamins and minerals, it’s one of the most preferred ways for dehydrating potato slices for regular uses. 

  • Take a bunch of fresh potatoes and then wash the skin properly so that all the dirt and bugs can be removed. You can also scrub the skin if you aren’t satisfied with the regular washing procedure. 
  • Put the vegetable in a water pan and then allow it to simmer for around twenty minutes. You can put a pinch of salt if you are planning to make dried chips or fingers. 
  • After boiling it for twenty minutes, take those potatoes out and place them in an ice bath which will help you to lower the temperature. After this, put them in the refrigerator and leave them overnight. This will allow you to cut the vegetable into thin slices the next day. 
  • After taking out the frozen potatoes, cut them into very thin slices, maintaining an even thickness throughout. You can either peel them off or leave the skin as it is. But, we would suggest leaving the skin since it is a rich source of antioxidants and vitamins. 
  • Once the slices are prepared, arrange them in single layers on the dehydrator trays. Even though the slices are thin, you cannot place two or more pieces in a stacked form on the trays since that will reduce the efficiency of drying of the appliance. 
  • Put these trays inside and then turn the temperature to a hundred and twenty-five to hundred and thirty-five degrees Fahrenheit. Set the times to ten hours, and then leave the trays inside. 
  • Once the indicator will go off, take the trays out. The dried slices can become brittle or leathery as per the time setting of the dehydrator. This is how to dehydrate potatoes with a food dehydrator.

Black Dehydrated Potatoes? Use Lemon Juice

In the method mentioned above, there is one little problem- the potato slices can become black which won’t be a desirable condition for dehydrating the slices. That’s why you need to know how to dehydrate potatoes without blackening the pieces. This can be easily done if you use the lemon juice or any other source of Vitamin C. 

  • After you have washed the potato skin thoroughly and scrubbed them, dry the potatoes by patting them between kitchen towels. 
  • Remove the skin properly without losing large chunks of the fleshy part inside. Once done, make thin slices of the potato such that each such piece will have a uniform width.
  • After you get all the slices, put them in an ice bath. Before this, add a little amount of lemon juice depending on the volume of the potato slices. For example, if you have sliced three to four potatoes, you have to use at least a cup of lemon juice in the ice bath. 
  • Place this entire pan on the oven and then simmer it for around three-four minutes. Once over, take the pan out off the heat, and then transfer the potato slices to another bowl having ice cold water and lemon juice. 
  • Check the temperature of the slices periodically and wait for them to cool down. Once the slices will get their normal temperature back, start arranging them on the dehydrator tray in a single layer. Do not overcrowd them since that might alter the drying rate. 
  • Set the temperature of the dehydrator to a hundred and twenty-five degrees Fahrenheit and leave the slices for a minimum of six hours. After this set time, take the trays out and check whether the slices have hardened or not. If you feel a little amount of softness in the flesh, put the trays back for another couple of hours till they get hardened and you get the dried potatoes

Why You Need To Blanch Potatoes Before Dehydrating Them?

Blanching potatoes and then dehydrating them – If you want to know how to dehydrate potatoes while helping them to retain the white, cream color, then you need to learn about blanching the vegetable and then using the dehydrator. 

  • While washing the potatoes properly under the cold water, use a scrubber to ensure that you are cleaning the skin and removing all the dirt and bugs. Since potatoes are grown under the soil, there are high chances that the skin will have some soil on it, 
  • Once the vegetable is washed, you can peel off the skin or leave them as it is. But, if you want to enjoy the nutritional value of the vegetable completely, it will be better to leave the skin. Cut the potatoes into thin slices which will make it easier for dehydrating potatoes. 
  • Do not leave the slices out in the open since that can trigger rapid oxidation and turn the flesh brown in color. Once you are finished with a single potato, place them into a water bowl and then move onto the next piece. 
  • When all the potatoes are cut and placed in the water, switch on the gas and allow it to boil for at least five minutes. Using a fork, check whether the potatoes are crumbling or breaking. If yes, take the bowl out of the heat and leave it for about a minute. This is the process of blanching where you make vegetables soft using boiling water. 
  • Now, strain the water and then take out the potato slices off the strainer. Carefully place the slices on the dehydrating tray without breaking them off. Place them in a single layer so that they can get dried effectively without any hassle. 
  • Put the trays inside and turn the temperature to a hundred and twenty-five degrees to a hundred and thirty-five degrees Fahrenheit. Keep the timer to six hours minimum since that is the time it will take to dehydrate the potato slices. 
  • Once the alarm will go off, take the trays out and check whether the slices have become hard or not. If some of them are still soft, separate those slices, arrange them on the trays, and again put them inside the appliance for making dried potato slices.
