The invention relates to a food processing system (100) able to deposit and/or deliver food under a certain pattern and to heat and/or cook at least part of it, the deposition being done onto a deposition surface (103) by at least a deposition head (102) in one or a plurality of shapes and/or layers； the food processing system (100) further comprising cooking means, these cooking means comprising: - at least a laser source (110) of the diode type generating at least a laser beam (112) with a certain power and wavelength； - an optical system (120) designed to collimate and/or focalize and/or homogenize the laser beam； - a steering system (130) directing the laser beam from the optical system towards the food pattern deposited onto the surface (103), the steering system being able to cover a certain scanning area (111)； such that the laser beam (112) is directed to at least part of the food pattern as it is deposited onto the deposition surface (103) or after it has been deposited so as to selectively heat and/or cook at least part of the deposited shapes and/or layers. The invention further relates to a method for preparing a foodstuff by using a food processing system (100) as the one described, the method comprising the following steps: - depositing onto the deposition area (103) a certain food pattern in one or a plurality of shapes and/or layers； - activating the laser simultaneously or successively to the deposition of the food pattern to heat and/or cook at least part of the deposited shapes and/or layers.La présente invention concerne un système de traitement d'aliments (100) permettant de déposer et/ou distribuer des aliments selon un certain motif et à chauffer et/ou cuire au moins une partie de ceux-ci, le dépôt étant effectué sur une surface de dépôt (103) par au moins une tête de dépôt (102) dans une ou plusieurs formes et/ou couches ； le système de traitement d'aliments (100) comprenant en outre un moyen de cuisson, ledit moyen de cuisson comprenant : -
