A method for producing a frozen risotto or alike ready-to-eat dish based on rice, barley, wheat or spelt. For risotto the steps include, adding to rice the necessary liquid and particulate ingredients and cooking all the above ingredients up to desired cooking degree, rapidly cooling the thus prepared risotto and feeding it into a dosing apparatus, which forms sphere-like portions of a predetermined weight or volume, which are subjected to ultra-fast freezing and then packaged.
