How about dehydrating food in convection ovens? It's an oft-asked question.

While electric food dehydrators are specially designed with food drying needs in mind, many people are surprised to learn you can also use your standard convection oven at home too!

The key lies in using the enhanced temperature regulation and smooth consistent air circulation that convection ovens offers over conventional no-fan ovens.

With their precise temperature and fan adjustments, a convection oven successfully removes water from sliced fruits, vegetables and more, concentrating flavors and textures just like a regular electric dehydrator.

With close monitoring and food rotating, this advanced oven style is a great alternative for dehydrating a wide variety of ingredients thanks to its unique heat, moisture, and air flow capabilities.

And if you’re just starting and don’t want to splurge on a dehydrator AND you already have a convection oven, then I say, “Try it!”

Frequently Asked Questions:

Dehydrating Food in Convection Ovens is a Quick and Easy Way to Dry Foods

Convection ovens can be used to dry food. Dehydrating food in a convection oven is a quick and easy way to preserve fruits, vegetables, and meat, and seafood.

To dehydrate food in a convection oven, start by preheating the oven to the lowest setting. Place the food on a wire rack and set it inside the oven. Leave the door open slightly to allow air to circulate. Use the handle of a wooden spoon to keep the door open a bit.

Check on the food every few hours, and remove it from the oven when it is dehydrated to your desired level.

What IS the Difference Between a Regular Oven and a Convection Oven?

What's the difference between a convection oven and a regular oven, you ask?

A convection oven has a fan that circulates the hot air, evenly cooking the food. A regular oven does not have a fan, and the hot air can become stagnant, causing uneven cooking.

Additionally, convection ovens typically cook food faster than regular ovens. So, if you're looking to dehydrate food quickly, a convection oven is the way to go.

Having said that, I prefer to use a food dehydrator that is specifically designed to dry food properly!

Convection Oven Fans

When using a convection oven (that uses a fan for air circulation), you’re almost ready to go.

One thing you need to check with your convection oven is that you can set the temperature below 200°F as our fruits and vegetables need to be dehydrated at 125°F  to 135° F degree range.

Any hotter than that range and you’ll be likely to cook—rather than dehydrate—your fruits and vegetables.

Air Circulation is Crucial

To dehydrate food properly and get consistent results, you need to have good air circulation.

With a regular oven, be it your everyday electric or gas oven, leave the oven door slightly ajar to create better air circulation, so the moisture can escape.

This means monitoring your oven temperature, so you’ll need to have a thermometer in there to make sure you’re dehydrating your foods at an even temperature.

Again, if it's too hot you’ll be cooking your food. Too cool means you’ll spend hours drying it out.

Again, I have to repeat myself. When you have a food dehydrator that is designed to dry food, you don't have to worry about air circulating correctly. Granted, I do rotate my trays. With a Nesco, it's so easy. Unstack, re-arrange, and put the lid back on.

Limited Oven Shelf Space in Convection Ovens

The oven rack space and number of racks available in your convection oven is limited, usually to two.

Plus, the rack's bars are spaced too far apart—thus resulting in the likelihood of your food falling down to the bottom of the oven!

Remember, when you’re dehydrating food, it SHRINKS. A lot!

You guessed it, folks. I'm going to add here that with a food dehydrator, you're not limited to how many trays to use. Well, of course, you'll refer to the owner's manual that came with your dehydrator as to what their maximum tray usage is.

You can get a Nesco that can handle as many as THIRTY trays! What?

Yes! But that's a LOT of food dehydration going on there. I wonder how tall that stack would be? And just imagine if your dog walked by with a big wagging tail and knocked the whole thing over! Ha.

Take the First Step…

Honestly, maybe it’s just time to take the first step and get either of these starter-model dehydrators.

I have both the Excalibur and Nesco starter-brand dehydrators and both work just fine. Neither one of them cost a fortune, either!

Dehydrators Cost Less to Run than Convection Ovens

Consider this: Dehydrators built for the job of drying food will cost less to run as compared to running your convection oven (or regular oven).

Plus, with a real dehydrator, you have many stackable trays/shelves that have the proper spacing and not just one (or two) solitary oven racks.
