A process for cooking a food product in a treatment chamber is shown, wherein the treatment chamber having two opposite walls each forming an electrode. The process comprises the steps of: (a) placing the food product, optionally in a surrounding liquid, in direct contact with the electrodes and (b) applying electric pulses generated by a pulsed electric field generator to the electrodes such that the food product is subjected to a pulsed electric field having a field strength of 10-180 V/cm. The total cooking time is 0.5-1000 seconds. Preferably, the number of pulses n is 1-2000000 and the pulses each have a duration τi of 1-20000 μseconds. The food product and, if present, the surrounding liquid, has an electric conductivity of 0.01-10 S/m. Also provided is a cooking system suitable for cooking a food product according to the process.
