The invention discloses reshaped crisp kudzuchips and a making method. The making method comprises the following steps of evenly mixing low-gluten or high-gluten flour, kudzu powder, shaping starch, fresh eggs, vegetable oil, water, a crisping agent, aspartame, maltodextrin, salt and other raw materials in a certain proportion and in sequence, repeating kneading, reshaping, then executing microwavepuffing, spraying seasoners and executing drying and packaging to obtain the reshaped crisp kudzuchips. By adopting a reshaping technology, the shaping rate, taste and crispness of the kudzu raw material for making the crisp chips are effectively improved; in addition, a microwave puffing technology is adopted, the shortcomings of high oil content, low nutritional value and high risk factors of conventional deep-fried puffed products are overcome,rapid non-deep-fried puffing of the crisp kudzuchips is achieved, and the operation is simple and fast. The crisp kudzuchips made by the method havebetter crispy mouthfeel and better retains the functional ingredients and characteristic flavor of kudzu.
