How to dry orange slices in an Aga
If you have an Aga, you have the perfect tool to dry orange slices. Its steady radiant heat preserves the oranges’ colour and prevents scorching, making the process simple and reliable.

Dried orange slices are a timeless Christmas craft. They bring natural colour, gentle fragrance and a traditional feel to garlands, wreaths, gift wrapping and tree decorations.
Why use an Aga
Unlike a conventional oven that cycles on and off, the Aga provides consistent warmth. The warming oven are ideal for dehydrating citrus slowly, helping the slices keep their shape and bright appearance.
What You Need
- oranges, choose older, slightly less juicy ones.
- Sharp knife
- Tea towel
- Baking trays
- Baking parchment or silicone liners
- Cooling rack
How to prepare the oranges
Slice the oranges into even rounds about 3-4 mm thick. Consistency helps them dry at the same rate. Blot each slice gently between a tea towel to remove excess juice. This step reduces browning and speeds up the drying process.
How to dry orange slices in the Aga
Line your baking trays with parchment or silicone liners and arrange the slices in a single layer. Place the trays in the warming oven.
Drying usually takes around four hours depending on slice thickness. Turn the slices every hour to ensure even drying. When they feel dry but still slightly flexible, transfer them to a cooling rack to finish firming up.
Tips for best results
- If slices begin to darken place them on top of the Aga to finish air drying overnight.
- Blood oranges, lemons and limes add colour variation.
- A light dusting of cinnamon adds fragrance.
How to use dried orange slices
Dried oranges work beautifully in many festive projects. I strung mine onto twine for a simple garland. But you could also add them to wreaths, tied onto gifts with twine or hang them on the Christmas tree.
