Wash and Slice: Rinse oranges thoroughly. Slice into thin rounds, about 1/8 to 1/4 inch thick for even drying.
Preheat Oven: Set oven to 175°F (80°C). If using a dehydrator, follow the manufacturer’s temperature guide for citrus.
Arrange Slices: Line a baking sheet with parchment. Place orange slices in a single layer without overlapping.
Optional Flavoring: Sprinkle lightly with cinnamon, sugar, or brush with honey for added taste.
Dry Slowly: Bake in the oven for 2–3 hours, flipping slices halfway through to ensure even drying. Goal: remove moisture without burning.
Cool and Store: Let slices cool completely before storing in an airtight container. They last up to 2 weeks.
Serve: Enjoy as a healthy snack, garnish for drinks or desserts, or thread into holiday décor.
