Big pao is a variety of baozi, the famous Chinese steamed buns. Consisting of a soft delicate bun and a delicious savory filling, they are similar to other steamed bun types, but are usually larger in size. The pastry is made with yeasted dough, which develops a tender, springy texture when steamed.

The filling is usually a delicious mixture of minced meat, mainly pork or chicken, shiitake mushrooms, and green onions, all doused in a fragrant sauce infused with soy sauce, oyster sauce, and sesame oil. Some versions might include Chinese sausage, while quarters of hard-boiled eggs are a welcome addition, usually positioned inside or on top of the meat filling.

Big pao buns are typically served as an afternoon snack or a hearty breakfast. They are mainly prepared at home or eaten as a takeaway meal, and similar varieties can be found in Hong Kong, Singapore, Malaysia, Indonesia, and Taiwan.
