Fourteen fluffy steamed buns filled with cooked char siu and a thickened oyster-soy sauce.

A fluffy Cantonese dim sum bao

This version wraps cooked char siu in a soft yeast-and-baking-powder dough, then steams the filled buns. It makes fourteen bao. The sauce is thickened separately into a jelly, cooled and mixed with chopped, ready-cooked char siu. This bread record uses shop-bought cooked char siu, an option the recipe page explicitly permits; it does not include a separate method for preparing pork.

The author places Char Siu Bao in Canton/Guangdong dim sum and describes a fluffy, sweeter wrapper with filling prepared before wrapping. The open top is a characteristic of this version; a standard pleated close is offered as an alternative. This modern recipe gives no dated first attestation or precise historical birthplace, so the record preserves the regional context without claiming an origin date. The author also names oyster sauce as a seafood-allergy concern and suggests a mushroom-based vegetarian alternative.

Make the jelly filling and dedicated dough

The onion first perfumes a small amount of oil. Water, oyster sauce, char siu sauce and dark soy boil briefly; removing the onion leaves a smooth sauce, though the author allows it to be chopped and retained. A starch slurry then thickens the sauce until it sets like jelly. Cool that base before mixing in the chopped cooked char siu so the filling stays together while the wrappers are shaped.

This dedicated dough differs from the author's other bao methods. The formula combines flour, sugar, baking powder, instant yeast and neutral oil, then gradually adds lukewarm water. Hand mixing includes a ten-minute covered rest and a short knead; the mixer option kneads for about eight minutes. Wei Guo says the added baking powder lets this formula go directly to shaping without a first proof. Flour choices change the water amount: the page gives 180 g for bao or cake flour and 190 mL for all-purpose flour. That distinction is retained rather than averaged.

Fill, shape, proof and steam

Divide the dough into fourteen portions and keep pieces covered until use. Roll each into a 9–10 cm disc with a thicker centre and thinner rim. Put about 20 g filling in the middle. The featured open-top fold is demonstrated in the recipe's tutorial; the author also points to a regular pleated alternative in the linked bao guide. This is a bread-shaping technique only; the char siu itself is already cooked and purchased/prepared separately.

Line steamer baskets with parchment, or lightly oil the metal or plastic surface. Let the assembled buns rest uncovered for about thirty minutes, until they look plump and light. Bring the water to a full boil, cover the steamer and cook over medium-high heat for ten minutes without opening the lid. The page serves them straight from the steamer and gives a three-minute steam reheat for refrigerated cooked buns. USDA guidance says cooked leftovers should reach 165°F (74°C) throughout; check the filling centre when reheating buns containing cooked and chilled char siu. The source gives no measured temperature for its initial ten-minute steam, so that time is not represented as a validated internal endpoint.

Raw flour remains uncooked through mixing and proofing. CDC advises against tasting raw dough and recommends cooking flour-containing dough according to recipe directions, with cleaning after handling. The filling contains oyster sauce; the source identifies a vegetarian mushroom-sauce alternative for readers avoiding seafood.

Method

Risks and precautions · Standard risk
Raw flour and dough before steaming

The wrapper dough contains uncooked flour until steaming. Do not taste raw dough.

Hazard source
Reheating cooked pork filling

The filling is made with cooked char siu and the recipe offers refrigerated cooked leftovers. The source gives a three-minute reheating time but no internal temperature.

Hazard source
Seafood ingredient in the filling sauce

The recipe includes oyster sauce and advises readers with seafood allergies to use a vegetarian alternative.

Hazard source

Do not taste raw dough; cook the flour-containing dough by steaming as directed and clean hands, bowls and tools after handling raw flour.

Control source

If reheating buns that contain previously cooked and chilled char siu, check that the filling centre reaches 165°F (74°C) with a food thermometer.

Control source

Keep oyster sauce visible in the ingredients; the source suggests a mushroom-based vegetarian sauce for seafood allergy concerns.

Control source

This bread version uses ready-cooked char siu as a filling. The source permits shop-bought char siu and does not provide a pork-cooking method here.

Contains wheat, soy sauce and oyster sauce. Check packaged char siu and sauces for additional allergens.

For reheating buns with previously cooked and chilled char siu, reach 165°F (74°C) in the filling centre. The source's 3-minute reheating instruction is not a measured safety endpoint.

The source's final steaming time is 10 minutes, but it does not give a temperature or internal endpoint for the filled bun.

  1. Prepare the filling sauce first. Heat ½ tablespoon neutral oil in a pan and fry the sliced onion until slightly golden and fragrant.
  2. Add 120 g water, the oyster sauce, char siu sauce and dark soy sauce. Bring to a boil for 30 seconds. Remove the onion with a slotted spoon; the source allows keeping it if finely chopped.
  3. Mix 2 tablespoons tapioca starch (or cornstarch) with 3 tablespoons water. Over the lowest heat, stir the slurry into the sauce until it sets into a jelly. Transfer it to a bowl to cool.
  4. Coarsely chop 130 g ready-cooked char siu, mix it into the cooled jelly and set aside. The source permits shop-bought char siu; this bread recipe does not include a pork-cooking method.
  5. For hand mixing, combine the flour, sugar, baking powder, yeast and 1½ tablespoons neutral oil. Gradually add 180 g lukewarm water while stirring with chopsticks or a spatula. Bring the mixture together by hand into a rough dough, cover for 10 minutes, then knead about 2 minutes until very smooth. If using all-purpose flour, Wei Guo specifies 190 mL water.
  6. For a stand mixer, put all dough ingredients in the bowl and knead on low for about 8 minutes until smooth. Choose either mixing method.
  7. Divide the dough into 14 equal portions. Keep unused pieces covered. Roll each piece into a 9–10 cm disc, thinner at the edge and thicker in the centre.
  8. Put about 20 g filling in the centre of each wrapper and shape the bun using the open-top folding method shown in the recipe's linked tutorial; the author also points to a regular pleated alternative in the linked bao guide.
  9. Line the steamer baskets with parchment, or lightly oil a metal or plastic steamer. Arrange the buns with space between them and leave uncovered for about 30 minutes, until light and plump.
  10. Bring water to a full boil in a wok or pot. Set the steamer baskets in place, cover and steam over medium-high heat for 10 minutes without opening the lid. Serve immediately.
  11. For cooked leftovers, Wei Guo gives refrigeration in an airtight container for up to 3 days. Reheat by steaming for 3 minutes. If reheating buns with previously cooked and chilled char siu, verify the centre of the filling reaches 165°F (74°C), in line with USDA guidance for cooked leftovers.
