A Vietnamese steamed filled bun

Bánh bao is a steamed filled bun. This from-scratch version combines self-rising flour and instant yeast in a soft dough, then encloses seasoned ground pork, a hard-boiled quail egg, mushroom, and Chinese sausage. The author also offers peas and carrots as an option. This recipe follows that particular pork-and-egg preparation; it does not represent every regional or household bánh bao filling.

The recipe precooks the pork portions for 7–8 minutes but gives no internal endpoint. CDC advises using a food thermometer rather than colour or texture and lists 160°F for ground pork. Check each portion's thickest meat section before wrapping it, avoiding the hard-boiled egg. The final 10-minute steaming step cooks the dough around filling that has already reached this endpoint.

The recipe author says cooked leftover buns can be wrapped individually, frozen, then reheated in a microwave or steamer. The page gives no storage duration or reheating temperature, so the catalogue does not add one.

Method

Risks and precautions · Elevated risk
Ground pork

The filling contains raw ground pork, which can carry harmful germs if it is not cooked through.

Hazard source
Raw flour

The dough contains uncooked flour before steaming; raw dough should not be tasted.

Hazard source

Precook every pork portion and verify its thickest meat section with a clean, thin-tip food thermometer at 160°F (71°C), avoiding the quail egg. Continue steaming as needed; the source's 7–8-minute estimate is not a substitute for this check.

Control source

Do not taste raw dough. Cook the buns before eating and wash hands, bowls, utensils, and work surfaces after handling flour or dough.

Control source

Keep raw pork and its utensils separate from ready-to-eat foods; wash and sanitize the thermometer after checking the pork portions.

Control source

Cooked pork portions and hard-boiled quail eggs are enclosed in the dough before final steaming; do not wrap pork portions until each has reached the thermometer endpoint.

The recipe gives no proofing temperature or steam temperature. Keep the steamer supplied with water and avoid contact between water and buns.

Hot steam and metal steamer parts can cause burns.

The author recommends freezing individually wrapped cooked leftovers and reheating in a microwave or steamer, but gives no duration or reheating endpoint.

  1. In a microwave-safe bowl, warm the milk in the microwave for 1 minute. Stir in the dough sugar until dissolved, then add the instant yeast and stir gently. Leave for 10 minutes, until frothy.
  2. Put the yeast mixture and sifted self-rising flour in a stand-mixer bowl. Mix with a dough hook on medium-low until the dough comes together loosely. Add 2 tablespoons vegetable oil and mix on low until incorporated and the dough mostly pulls away from the bowl.
  3. Cover the bowl and leave the dough in a warm place to rise for 1 hour.
  4. Hard-boil and peel 12 quail eggs. Heat the remaining 2 tablespoons oil in a small frying pan over medium-high heat. Sauté the chopped onion until soft and aromatic; set aside to cool.
  5. Mix the ground pork with the filling sugar, oyster sauce, bouillon powder, sesame oil, black pepper and minced rehydrated wood ear. Stir in the cooled onion, optional peas and carrots, and diced Chinese sausage. Divide into 12 equal portions, placing one hard-boiled quail egg in the centre of each portion and shaping the pork around it.
  6. Set the pork portions in a steamer and precook for 7–8 minutes. Use a clean, thin-tip food thermometer to check the thickest meat section of each portion, avoiding the quail egg; continue steaming until every portion reaches 160°F (71°C). Do not rely on colour or the stated steaming time to judge ground-pork doneness.
  7. Divide the risen dough into 12 equal portions, about 117 g each. Shape each into a ball and roll it into a circle about 5½ inches across.
  8. Place a cooked pork-and-egg portion in the centre of each dough circle. Top with slices of the remaining Chinese sausage. Draw the dough over the filling, fold and pinch the edges together, then twist and pinch the top to seal.
  9. Set each bun on a 2×2-inch parchment square or in a cupcake liner. Leave about 1 inch between buns in the steamer so they can expand. Add the white vinegar to the steamer water and wrap the lid with a clean kitchen towel to catch condensation.
  10. Steam the assembled buns for 10 minutes. Remove the steamer carefully, then remove the parchment or liners before eating. Serve warm. The recipe author says cooked leftovers can be wrapped individually and frozen, then reheated in a microwave or steamer; no storage duration or reheating temperature is given.
