The present invention relates to the field of food and particularly relates to dried puffers and a preparation method thereof. The provided dried puffers consist of the following components in parts by weight: 100 parts of dried puffer back muscle meat, 2.5-3.0 parts of salt, 1.5-2.0 parts of white granulated sugar, 1.5-2.0 parts of cooking wine, 1.0-1.5 parts of baijiu, 1.0-1.5 parts of soy sauce, 4-5 parts of honey, 0.4-0.6 part of Chinese prickly ash, 0.4-0.6 part of cassia bark, 0.8-1.0 part of dried chili, 5-7 parts of garlic and 3-6 parts of ginger. Vacuum freeze-drying technology and blow drying are combined for manufacturing the dried fish, the preparation method avoids problems that the vacuum freeze-drying technology enables the dried fish products to be excessively loose and porous, easy to absorb water and regain moisture, lack of chewing, etc., and can also very well solve problems of uneven heating by a direct curing, long curing time, excessive dryness and hardness of the dried fish products, so that a finished product is loose but not lacking in chewiness and texture, and has a great potential as high-grade convenience food.
