• Thoroughly wash the oranges. Use a mandoline or sharp knife to cut the oranges in approximately 4-5mm slices. Consistency is key here so they oranges will dry evenly. Carefully blot the sliced oranges with a paper towel to remove excess liquid.

For Oven Drying:

• Preheat the oven to 200°F. Line two baking sheets with parchment paper. Spread the slices on the lined baking sheets. The oranges may be touching, but should not be overlapping.
• Bake for 2-4 hours, turning every 30 minutes, 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 3-6 hours, checking the dryness occassionally 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.
