A puffed broad bean is produced from broad beans, and is concretely obtained through the following steps: crushing and peeling of the broad beans, microwave treatment, immersion and water absorption, high temperature gelatinization, refrigeration, frying, slurry wrapping, baking, mixing, drying, and pectin cladding. Refrigeration, mixing and slurry wrapping treatments are adopted, so the finished broad bean has greatly increased crispness, bright and attractive surface and many tastes; a traditional powder mixing technology is merged into a slurry wrapping technology, so the broad bean has a bright and neat surface; and the surface of the dried broad bean is coated with fruit gel, so the obtained broad bean has soft inside and crispy inside, and has sweet and tasty mouthfeel, and the mouthfeel and the appearance of the puffed broad bean are obviously improved.
