Dehydrated onions are a versatile ingredient to use in many recipes from adding flavor to soups and stews to making homemade onion powder and garlic salt.
Plus they help reduce food waste since they have a longer shelf life than fresh onions. Store dehydrated onions in Mason jars or other airtight containers to keep them fresh and flavorful for a long time.

Proper preparation of onions is key to successful dehydration. This starts with choosing the right type of onion and then cleaning and cutting the onions properly.
Start by cleaning the onions to remove any dirt and debris. Then peel the outer skins and slice them into pieces.
For best drying results it’s important to cut the onions into uniform slices or pieces. Uniformity in size ensures even drying so some pieces don’t dry out while others stay moist. For dried minced onion it’s best to use a food processor to finely chop the onions into small pieces before spreading them on a drying tray. Preparing onions for drying also means removing excess moisture by gently patting them dry with a paper towel before placing them on the dehydrator racks.
