Dehydrated tomatoes are one of the most popular dried food items people consume. In the modern age air fryer is a common kitchen appliance. Therefore, it is a common question among us how to dehydrate tomatoes using an air fryer. In this article, I’m going to answer this question with step by step procedure. 

Dehydration is a slow process. It has to be carried out at a very low temperature for a long time. It is the art of getting out the water from tomatoes or other foods without destroying the enzyme and other food values. Some people may have questions in mind about whether it is possible to dehydrate tomatoes in the air fryer. The straightforward answer is that the air fryer should have a dehydrator function to handle this boring kinda cooking. If your air fryer does not have the option, then find the best dehydrator for fruits and vegetables here.

Mineral contents of this vegetable include iron, potassium, copper, and magnesium. The bad about tomatoes is that the majority of the calories come from sugar. It is also very high in sodium. Therefore, we should not take it in excess amount in a single serving. 

Ingredients and accessories needed

Tomatoes and salt are the only ingredients that you need to prepare dried tomatoes. Kitchen appliances that you need are a kitchen knife to slice the tomatoes in the proper size, a chopping board, hand gloves, and an air fryer with a dehydrator option if you do not already have it. You may also use a cooking thermometer to monitor the temperature.

Step by step process – Drying tomatoes in air fryer 

Step 1

First, you need to collect the ingredients and required accessories. Tomatoes and salt are the mandatory items. If you are a dry food lover, then I’d suggest you get the accessories as well. 

Step 2

Take the tomato on a flat surface, preferably, on a chopping board. Now slice in into two if you are dehydrating plum tomatoes. For round-shaped ones, cut into four pieces. You may scrape the seeds out with a little spoon gently. Ensure the pulps remain intact.   


Step 3

Now turn down the halves of the pieces and make one or two slits on the skin. These slits will allow the air to pass through and expedite the dehydration process. 

Step 4

In this step, sprinkle salts on the pulps. Salts will enhance the draining of water. 

Step 5

Now it is time to arrange the slices on the air fryer. I would highly recommend choosing an air fryer with racks. It also needs to have a dehydrator option. Keep some spaces between the slices for uniform air passage. 

Step 6

Set the temperature of the air fryer at around 120F to 130F. If your air fryer does not support that low temperature, then you should replace it with a new one. Cooking time is more than 8 hours. 

Step 7

Turn the tomatoes every two hours and check whether they are dried. If the size of the slices is big, then it may take more time to complete the drying process. If you feel sticky, then stop the air fryer. 

Step 8

Store the dried tomatoes in a zip-top bag. Keep it in a dry place to store for up to 3 months. If you want to store them for more, then keep them inside the refrigerator. 


Can I use an oven to dry tomatoes? 

Tomatoes contain 93% water. To dry up the water, they need constant warm air for a long time. If you hasten the process, you will end up with leathery pieces that will not last long. The reason behind this is that at high temperatures the structure of the nutrition contents gets destroyed. Therefore, it is not a good idea to try dehydrating foods at high temperatures. Whether it is tomatoes or other fruits and vegetables, we should try to dry these at very low temperatures. Therefore, the ideal machine we should use is a dehydrator or an air fryer with a dehydration option.
