Preheat the oven to 170C (340F) fan-forced.
Grease and line a cake tin. I use a round tin.
Add the beaten egg to the rice and mix to combine. Add the milk and stir through.
Mix the herbs and onion through then add the butter, salt and curry powder.
Pour the mixture into the prepared tin and bake for approximately 45 minutes or until the top browns and it feels firm when pressed in the middle.
Leave to cool then cut up and serve. It can be served hot or cold.
