To dry oranges in the oven, you'll want to preheat your oven to 200 degrees and prep a cookie sheet with a layer of parchment paper. Without the parchment or some sort of lining, the fruit will definitely stick to the surface, so just make sure you don't skip this step.

Dry at 125°F/52°C or lower for 18-36+ hours. While the recommended temperature for fruit is 135°F/57°C, oranges often brown during the drying phase as the sugars brown from the heat. Dropping the temperature can help prevent that, though you do have to add a little more time to the drying process.
What temperature do you dehydrate oranges at?
To make dried orange slices in a dehydrator simply set the temperature to 135F (60C), lay the slices out on the racks of the dehydrator and allow to dry out for approximately 5-7 hours.
Place whole oranges in a food dehydrator on drying racks or in a low-heat oven in a single layer on baking sheets. Turn occasionally to maintain shape. Leave in the food dehydrator or oven for 24 to 48 hours; larger oranges may require a longer drying time.

Dehydrated lemons and oranges are okay, but dehydrating does not capture the freshly-squeezed taste of citrus. I also freeze dried lemon and orange slices.
