Asian BBQ pork buns, or char siu bao, combine steamed yeast dough with cooled, cooked roast-pork filling. The six-bun home method below uses a manageable filling portion and a soft wheat dough.
Soft dough and savory-sweet cooked filling make these suitable for a shared dim sum table.
What Is Asian BBQ Pork Buns?
Char siu bao is a bun filled with cooked roast pork. Both steamed and baked versions have established places in dim sum and bakery cooking.
Diced cooked char siu is the pork ingredient in these buns. Mix it with a thickened savory-sweet sauce and cool the filling before enclosing it in dough.
A secure seal and a manageable filling portion matter more for a home bun than a required 12-15 pleats.
Pleating takes practice. Closed home buns need not imitate every restaurant’s cracked-top dough.
Six Home-Style Steamed Char Siu Buns
These are closed home buns with yeast dough and cooked-pork filling, not a promise of the cracked-top restaurant style. The formulation is a home adaptation, not a kitchen-tested claim.
Dough and Filling
- 250 g all-purpose wheat flour; 1 teaspoon instant yeast; 25 g sugar
- 140 ml lukewarm water, plus 5-10 ml only if needed; 1 tablespoon neutral oil; 1/4 teaspoon salt
- 150 g cooked char siu, diced small
- 1 tablespoon hoisin; 1 tablespoon oyster sauce; 1 teaspoon light soy; 1/2 teaspoon sesame oil
- 1 teaspoon cornstarch and 2 tablespoons cold water
- Mix flour, yeast, sugar and salt, then water and oil. Knead until smooth. Add only a little extra water if the flour remains dry; do not leave the dough crumbly. Cover and proof until noticeably expanded, often 1-2 hours depending on warmth.
- Combine filling sauces in a small pan. Stir the cornstarch with cold water, add and simmer until thickened. Stir in cooked pork and let it cool promptly, refrigerating if it must wait.
- Divide dough into six equal pieces by weight. Roll each into a disc with a slightly thicker center and thinner rim.
- Divide the cooled filling evenly. Use less if it prevents the rim sealing. Gather the rim and pinch shut; a fixed number of pleats is unnecessary.
- Set each bun on a parchment square, leave room between them and proof until puffy. Steam over boiling water above the waterline, starting with about 12-15 minutes and checking that the dough has no wet raw layer and the cooked-pork filling reaches 165 F (74 C).
- Turn off the heat, wait briefly and lift the lid away from your face. Serve warm; baked buns require a separately designed dough and method rather than merely putting these into an oven.
Asian BBQ Pork Buns Variations
Steamed and baked char siu buns both have established uses. They need different doughs and cooking methods; baked does not mean less authentic.
For a vegetarian filling, choose a tested mushroom or tofu version and check the sauces; a pork filling cannot be made vegetarian by removing visible pieces.
Serving Asian BBQ Pork Buns the Cantonese Way
Serve warm in a basket or on a plate, with space around the buns so they do not stick.
Tea and other dim sum make natural accompaniments, with the choice guided by your guests.
Overfilling and insufficient proofing can make shaping difficult. Keep filling cool and use the dough’s expansion rather than a rigid proofing clock.
Frequently Asked Questions
Can I use purchased char siu?
Yes. Use cooked pork from a safe source and dice it finely. It should be chilled promptly before making the filling.
Can I swap gluten-free flour one-for-one?
Not reliably. This dough depends on wheat gluten; use a separately tested gluten-free bun recipe and check every sauce label.
Can I freeze the cooked buns?
Yes. Cool promptly, wrap and freeze. Reheat from frozen with steam until the filling reaches 165 F (74 C), not for a guaranteed few seconds.
Keeping Leftovers
Refrigerate perishable cooked food promptly in shallow containers, within two hours of cooking (one hour above 90 F / 32 C). Keep it cold at 40 F / 4 C or below. USDA generally allows three to four days for refrigerated leftovers; discard food left out too long. Reheat leftovers to 165 F (74 C), checking the center rather than relying on a few seconds or minutes.
