- Preheat the oven to 200°C/180°C fan.
- Lightly coat the potatoes with oil, season and prick them a few times with a fork.
- Arrange the potatoes on a baking tray, put them into the oven and cook for 45 minutes.
- Allow the potatoes to cool, then cut them in half and scoop out most of the insides from the skins.* Put them back into the oven, skin-side-up, for another 10-15 minutes.
- Remove the skins from oven, allow to cool again and fill with the coronation chicken. Top with a little chopped coriander and serve.
*Use the leftover potato to make gnocchi, or fry with leftover vegetables to make a hash and serve topped with fried or poached eggs.
