Abstract: A roasting and/or grilling apparatus for cooking purposes, having a cooking chamber, a food holding unit arranged in the cooking chamber, and a combustion chamber for arranging a heating apparatus. The combustion chamber surrounds the cooking chamber at least in sections at the sides and the combustion chamber is open to the cooking chamber. The combustion chamber and/or the cooking chamber also have an associated air inlet in a lower region and an associated air outlet in an upper region for the purpose of creating a chimney effect. A heating insert for arrangement in the roasting and/or grilling apparatus is also provided. The heating insert is exchangeable and is designed to accommodate a heat source. In this case, the heat source is a fossil fuel and/or a gas burner and/or a radiant electric heating element.
