Preheat the oven to 180 degrees Celsius (160 degrees Celsius fan-forced).

In a medium pan, heat up the oil over medium heat. Cook onion and bacon for two minutes, stirring until soft, and then add chicken, sauté until chicken is lightly browned, approximately five minutes. Add rice and stir for one minute.

Transfer to a large flame-proof, oven-proof dish and add the chicken stock, and stir well to combine. Cover with tin foil and bake for fifteen minutes. Uncover and bake for another twenty five minutes, or until almost all of the stock is absorbed and the rice is tender.

Remove from heat and stir in Parmesan and pepper before serving.
