Dehydrator vs. Oven

When choosing whether to use an oven or a dehydrator, here are some pros and cons that you may consider when making this decision. 

Let’s start with the dehydrator! You can dry many foods at the same time because of their size, layers, and trays. It even has a thermometer and timer to make it easier to monitor.

It is specially made to spread heat and air for effective drying of food. However, a dehydrator can also be expensive. It also uses electricity and space in your kitchen, not a good option for small space living.

Meanwhile, an oven is more readily available than a dehydrator. It also dries the food quicker. Oven drying also doesn’t cause too many changes in the food. In fact, you may already have an oven right now.

Although, using an oven can be tricky when it comes to setting the time and temperature. It is also limited in terms of space because, most of the time, there are only one or two layers in the oven.

In conclusion, choose whatever depends on your most important factors! For instance, if your concern is space, it’s best to use a versatile oven. The dehydrator might be better if you want to dry food in bulk.

Important Tips

What do you need to remember when using your oven as a dehydrator?

Be patient

All good things take time, and dried food is certainly not an exception. After all, the best results are always worth waiting for, right? Drying foods can vary in drying time, some may even take a day or two.

Allow air

If your oven doesn’t have a fan feature, then you can leave the door slightly open to allow air inside. It also helps you achieve a crunchy and crispy texture. Just don’t leave it wide open to get the results that you need.

Line the tray 

Place wax or parchment paper on the tray to keep the food together and to make cleaning easier. It will also make it easier for you to gather the foods after you have dried them.

Pay attention to the temperature

Dehydrate the food slowly at a low temperature to avoid burning it. Food can take several hours to dry, especially if they have water content. Check for the dehydrating time of the foods you want to dry.

Prepare the food well

Slice the food thinly, if needed. Evenly arrange it in a single layer with a bit of space in between to cook them all the way through.
