When talking about Vietnamese cuisine, besides familiar dishes such as bun cha, pho, and banh mi, banh bao is also a popular and beloved food. With its soft, fluffy outer layer, diverse fillings, and delicious flavor, bánh bao has become a favorite choice for many people.
What is banh bao? Where did it originate? Why do so many people love it? Let’s explore these questions in the article below.
What is Banh Bao?
Banh bao is a type of steamed bun made mainly from fermented wheat flour, which is then shaped and cooked by steaming. It usually has a soft, white, fluffy outer layer with a distinctive light and airy texture. The inside can contain various types of fillings, such as meat, eggs, vegetables, mung beans, or vegetarian ingredients.
Unlike many other types of pastries that are baked or fried, traditional banh bao is cooked using the steaming method. As a result, the bun maintains its soft, moist texture, natural flavor, and is easy to enjoy.

The Origin of Banh Bao
Few people know that behind the soft white outer layer and delicious filling of the familiar banh bao lies a long historical story that has lasted for thousands of years. According to many legends, this dish originated during the Eastern Han Dynasty and was created by the famous physician Zhang Zhongjing, one of the renowned medical sages of ancient China. Initially, the dish was not only made to be enjoyed but also to help people survive the harsh cold weather and food shortages at that time.
During the Three Kingdoms period, bánh bao continued to appear in a famous legend associated with Zhuge Liang. After the southern campaign and the event known as the “seven captures and seven releases” of Meng Huo, the Shu army faced difficulties on their way back to Chengdu because they could not cross the Lu River, where the water was turbulent and dangerous.
According to the legend, Meng Huo believed that crossing the river required a sacrificial offering of 50 human heads. However, Zhuge Liang did not want to sacrifice the lives of more soldiers, so he came up with a creative alternative. He ordered the making of buns shaped like human heads, with a flour-based outer layer and meat filling inside, and used them as a substitute for the sacrifice.
These buns were called “Mantou” (meaning “barbarian heads” or “Man people’s heads”). Over time, the dish gradually changed in shape and flavor, eventually becoming the popular banh bao we know today.
Today, banh bao is no longer just a traditional Chinese dish but has become a familiar part of Asian culinary culture. In Vietnam, Japan (Nikuman), Korea, Thailand (Salapao), and Myanmar (Pauk-si), bánh bao has its own unique versions that reflect the characteristics of each country.
From a dish connected to an ancient historical story, banh bao has crossed borders and time to become a symbol of creativity, adaptation, and the essence of Asian cuisine.
