The invention relates to a plain toast added containing galactooligosaccharide, and a production method thereof. Raw materials of the plain toast comprise second-stage fermented dough, warm fermenteddough and first-stage fermented dough, the second-stage fermented dough is mainly made of special high-gluten flour for bread, and the plain toast is made from, by mass, 20-40% of the warm fermented dough and 80-120% of the double-fermented dough on the basis of the special high gluten flour for bread of the second-stage fermented dough. The production method of the plain toast combines a secondary fermentation method and a warm fermentation method, and adopts a secondary fermentation mode, and raw materials are subjected to stirring, dough forming, loosening, shaping, primary fermentation, exhausting, shaping, secondary fermentation, die filling, baking, cooling and the like. The fermentation time is shortened, meanwhile, the roast is soft and elastic; and the galactooligosaccharide is used, so the sweetness and the calorie are low, the intestinal microenvironment is improved, absorption of various trace elements in the wheat germ flour is promoted, the moisture retention can be improved, and the shelf life is prolonged.
