The invention provides cheese sausages and a preparation method of the cheese sausages. The method comprises the following steps: (1) carrying out pasteurization and lactic acid bacteria fermentation on raw milk to obtain a milk curd; cutting the milk curd into small blocks and removing milk serum to obtain granular milk curd; (2) filling the granular milk curd into a mold; after squeezing, de-molding to obtain a milk curd block; (3) cutting the milk curd block; adding salt and aspergillus oryzae spore liquid and stirring; filling to sausages to obtain the cheese sausages, wherein the adding amount of the aspergillus oryzae spore liquid with the concentration of 10<5>cfu/mL to 10<6>cfu/mL is 0.2L/kg to 0.6L/kg according to the mass of the milk curd block; (4) exhausting and drying the surfaces of the cheese sausages by blowing; after fermenting the cheese sausages to be ripe, packaging in vacuum to obtain the cheese sausages. A production process adopted by the preparation method is feasible and is easy to operate; cheese of the cheese sausages is originally processed cheese; the nutrient value is high; the cheese sausages get ripe by utilizing a specific enzyme system of aspergillus oryzae, a specific fermentation flavor is given to the cheese sausages, and the koji flavor is prominent; the cheese sausages are suitable for consumers of China to eat.
