• Thoroughly wash the oranges. Use a mandoline or sharp knife to cut the oranges in approximately 4-5mm slices. If you find your oranges are too soft, place them in the freezer for about 1 hour before slicing to help them firm up.
• Place the orange slices in an even layer on a paper towel. Cover with another layer of paper towels and press with your palms to remove excess moisture from the oranges.

For Oven Drying:

• Preheat the oven to 175°F. Line two baking sheets with parchment paper. Spread the slices on the prepared baking sheets. The oranges may be touching, but should not be overlapping.
• Bake for 3-4 hours, turning every hour, until completely dried and crisp to the touch. Drying time will depend on the thickness of your slices. Let cool, then store in an airtight container.

For Dehydrator Drying:

• Set the dehydrator to 135℉. Spread the sliced oranges on the drying racks. The oranges may be touching, but should not be overlapping.
• Dry for 4-8 hours, flipping and checking the dryness occasionally after about 2 hours. Drying time will depend on the thickness of your slices. Continue drying until the slices are completely dried and crisp to the touch. Let cool, then store in an airtight container.
