Choose how you want to cut your apples. Cut into rings with apple skin, rings without apple skin, cut into half to make large apple chips or quartered to make small dried apples.
Cut apples into thin slices.
Prepare a bowl with lemon juice and water. Mix together.
Submerge your apple slices into the water lemon juice to prevent browning.
Pat dry your apple slices with a clean fresh towel. Your apples will take so much longer to dehydrate if they are soaked.
Turn on your food dehydrator.
Place apple slices into racks and spread out so that each slice sits on its own.
Stack racks over your food dehydrator.
Leave the apples to dehydrate and check on your apples after a few hours.
Your apple slices will take about 12-14 hours to dehydrate, depending on the apple variety, the dehydrator heat setting, and the thickness of your apple slices.
Your apples are done drying when they are crispy. Allow the slices to cool for 5 minutes and then store in an airtight container until further use.
