A flavoring device (200； 400； 1000) is proposed. The flavoring device (200； 400； 1000) is adapted to be associated with a cooking chamber (315； 515) of a cooking oven (100； 100′) adapted to cook food stored therein. The flavoring device (200； 400； 1000) comprises at least one flavoring casing (205； 1003) having an air inlet opening (210； 1012) arranged for allowing air to enter said flavoring casing (205； 1003), a flavoring air outlet opening (270c； 1030b) arranged for allowing air contained within said flavoring casing (205； 1003) to pass to said cooking chamber (315； 515), and a flavoring air path (600； 1061) traversing said flavoring casing (205； 1003) and fluidly connecting said air inlet opening (210； 1012, 1036) to said flavoring air outlet opening (270c； 1030b). The flavoring casing (205； 1003) houses, at least while in operation: a heating element (305； 405； 1019) arranged in said flavoring air path (600； 1061) for heating the air flowing through said flavoring air path (600； 1061), and a flavoring substance rack (240； 1027) arranged at least partially in said flavoring air path (600； 1061) downstream said heating element (305； 405； 1019) and adapted to contain at least one flavoring substance. Moreover, the heating element (305； 405； 1019) is housed spaced apart from the flavoring substance rack (240； 1027) in such a way that, in operation, heat is transferred from said heating element (305； 405； 1019) to said flavoring substance rack (240； 1027) mainly by air flowing inside the flavoring casing (205； 1003) from the air inlet opening (210； 1012) to the flavoring air outlet opening (270b； 1030b) through said flavoring air path (600； 1061).
