Bao (baozi) are steamed, filled buns from Chinese cuisine, made from a yeast-leavened dough of flour, water, and yeast. They are distinct from mantou, the plain, unfilled steamed bun often served alongside dishes rather than filled.
Bao are steamed in a bamboo steamer and filled before cooking. Savory fillings commonly include pork, beef, chicken, or vegetables seasoned with soy sauce, garlic, and ginger; sweet versions may hold red bean paste, custard, or fruit.
Bao are a common dim sum item and snack, and are traditionally associated with Lunar New Year celebrations as a symbol of prosperity. Regional styles vary, with larger, fluffier buns in northern China and smaller, more delicate versions in the south. Bao have also spread internationally, appearing with non-traditional fillings like pulled pork or fried chicken.
