Meanwhile, turn the Actifry on to get hot. After a minute or so, add the oil and let that get hot for a further minute. Drain the potatoes really well. Add the drained potatoes to the Actifry with the seasonings and allow to cook for at least 30 minutes. Test with a fork for doneness and cook for a further 5-10 minutes if necessary. This will change depending on how well you preheated your Actifry and how full your oven is.
