The invention discloses a composite flavoring and a production method thereof. The composite flavoring comprises cordyeps militaris and chicken meat serving as main raw materials, wherein the raw materials are crushed by using ultrasonic sound to improve extraction rate of nutritive materials and flavoring substances; the raw materials are enzymolyzed by composite protease; auxiliary materials such as leucine and the like are added for thermal reaction; and thus a composite flavoring of the cordyeps militaris and the chicken meat, which is a high-grade flavoring with unique flavor and good health-care function, is produced. The flavoring has the fresh flavors of the cordyeps militaris and the chicken meat, has the unique fresh fragrant characteristic by flavor producing reaction, has special nutritive components and is a novel high-grade flavoring with good development and application prospect. The composite flavoring can be widely applied to seasoning soups, noodle soup ingredients, hot pot soup ingredients and optional ingredients, stuffing of fast-frozen foods, home soups, steamed foods, boiled foods, fried foods, stewed foods, cold and dressed foods, barbecue and the like, is applied to special health-care foods and belongs to high-grade meat flavoring products.
