More specifically, the invention relates to a pizza oven accessory (10) for converting a kettle-type barbecue into a pizza oven. The pizza oven accessory (10) includes a hollow body (12) and a food receiving member (14). The hollow body (12) is receivable between a fuel receiving base (100) and a lid (102) of a barbecue so as to define in use a cooking chamber (22) within the hollow body (12) and between the base (100) and lid (102) of the barbecue. The hollow body (12) further defines an access opening (24) through which food is introducible or removable from the cooking chamber (22).
