The invention discloses a fresh cheese and a preparation method thereof. The preparation method comprises the following steps: 1, carrying out heat treatment of whey, and enriching denatured whey proteins to obtain a whey concentrate having 10-12% of dry matters; 2, adding the whey concentrate to raw milk, carrying out heat treatment, and cooling to obtain treated milk; 3, inoculating a starter, fermenting to the pH value of 5.4-5.5, adding chymosin, uniformly stirring, allowing the obtained mixture to stand, and continuously fermenting to the pH value of 4.6-4.7 for forming clotted milk; and 4, cutting the clotted milk, heating the system to 52-55DEG C in a 1-2DEG / min manner, carrying out heat treatment for 3-5min, heating to 58-60DEG C in a 0.3-0.5DEG C / min manner, carrying out heat treatment for 1-2min, cooling to 20-22DEG C, and discharging whey to obtain the fresh cheese. The fresh cheese has the advantages of substantially increased protein recovery rate and yield, good quality good mouthfeel, and effectively increased nutritional values and absorption rate, and can well satisfy modern nutritional requirements.
