Dry Foods in The Oven

A standard oven is the most common appliance in the kitchen and the easiest one to use for dehydrating food. It’s great for vegetables, fruit, and meat.

Cut your produce into 1/4 inch slices, lay them on an oven sheet, and bake for 6 to 10 hours. You’ll need to set the oven to 180 degrees F (or as close as your oven allows). Turn the food every hour or so. The juicier the food the longer it will take to dehydrate.

A little experimentation with temperature and time and your oven will produce great dehydrated foods. The only negative is that your oven will be on for a long time, which can get expensive.

Toaster Oven

A toaster oven is a great alternative to an oven for how to dehydrate food without a dehydrator.

The Outdoors

The area needs to reach a temperature of 90+ degrees F. Cut the tomatoes nice and thin, place on a tray, and cover with mesh so that flies can’t get to the food. You’ll need to leave them outside for at least a couple of days.

For herbs, tie them into a bunch, wrap in cheesecloth, and hang in a similar place.


It might be surprising, but a microwave is a good option for dehydrating quick-drying produce such as apples and herbs.

For herbs, lay the leaves out on a paper towel, and microwave them on high power for 2-4 minutes. Turn them every 30 seconds or so to avoid burning them. If they don’t seem quite dry enough after 4 minutes give them bursts of 30 seconds more until they are dry.

For apples, cut them nice and thin. You’ll want the slices even in thickness and no more than 1/4 inch. Lay them out on the rotating plate. Choose the defrost option on your microwave. Dry them for 30 minutes or and turn them every 10 minutes so that they don’t burn.
