How Long Does It Take to Make Bao Buns?

Quick Answer

Making bao buns (Chinese steamed buns) from scratch takes approximately 2–3 hours total. Most of that time is hands-off dough rising. Active preparation, including mixing, kneading, shaping, and filling, takes about 30–45 minutes. Steaming each batch requires 15–20 minutes.

The Dough

Bao dough is simpler than most bread doughs. The key ingredients are all-purpose flour, instant yeast, sugar, baking powder, neutral oil, and warm water or milk. The combination of yeast and baking powder gives bao their characteristic pillowy, cloud-like texture.

Mixing and Kneading (10–15 Minutes)

Combine dry ingredients, add wet ingredients, and knead until the dough is smooth and elastic. Bao dough should be softer and slightly stickier than standard bread dough. Knead for about 8–10 minutes by hand or 5–6 minutes with a stand mixer.

First Rise (60–90 Minutes)

Cover the dough and let it rise in a warm spot until doubled in size. In a warm kitchen, this takes about 60 minutes. In cooler environments, allow up to 90 minutes. You can speed this up by placing the covered bowl in an oven with just the light on.

Popular Fillings

While the dough rises, prepare your filling. Here are common options and their prep times:

• Char siu (BBQ pork): 15 minutes if using pre-cooked pork, 45+ minutes if making from scratch
• Pork and cabbage: 15–20 minutes for mixing and seasoning
• Mushroom and vegetable: 15 minutes for sauteing and seasoning
• Red bean paste: No prep needed if using store-bought
• Plain (mantou): No filling, just shape and steam

Shaping (15–20 Minutes)

Divide the dough into 10–12 equal portions. Roll each piece into a flat oval, add filling to the center, and pleat the edges together to seal. For open-faced bao, fold the oval in half over a light brush of oil. Place each bun on a small square of parchment paper to prevent sticking.

Steaming (15–20 Minutes)

Arrange buns in a bamboo or metal steamer, leaving at least 2 inches between each bun since they expand significantly during cooking. Steam over boiling water for 15–20 minutes depending on size. Do not open the steamer during the first 10 minutes, and crack the lid slightly for 30 seconds before fully removing it to prevent the buns from collapsing due to the temperature shock.

Tips for Perfect Bao

• Use a combination of yeast and baking powder for the fluffiest texture
• Add a small amount of white vinegar to the dough for extra-white buns
• Do not over-knead; the dough should be soft, not tough
• Let shaped buns rest for 15–20 minutes before steaming for a second rise
• Use medium-high heat for steaming, not a rolling boil

Can You Make Bao Buns Ahead?

Yes. Shaped, uncooked bao can be frozen on a parchment-lined tray and stored in freezer bags for up to 3 months. Steam directly from frozen, adding 3–5 extra minutes to the cooking time. You can also refrigerate the dough overnight after the first rise, which develops more flavor and allows you to shape and steam fresh buns the next day.
