Slice oranges to desired thickness. But also keeping the oranges as uniform in size as possible. Remember: the thicker the slices, the longer it will take to dry the oranges.
Layer the orange slices on a dehydrator tray evenly and avoiding overlap.
Set the dehydrator temperature to 135 degrees. And dehydrate for 6-8 hours until the orange slices are dry and crispy.
To use in decor, I found a simple small screwdriver or kitchen skewer works well for poking a hole in the dried oranges to use for hanging.
Kitchen twine or other rustic twine looks great for hanging the oranges on a Christmas garland or tree.
Use a hot glue gun for an easy way to decorate with the oranges on a Christmas wreath.
