- Prepare the Ingredients
Gather all your ingredients: 3.5 cups all-purpose flour, 1/4 cup sugar, 2 tsp active dry yeast, 1 tsp baking powder, 1 cup lukewarm milk, and 2 tbsp oil for the dough. For the filling: 1 lb diced char siu, 1 tbsp oil, 2 cloves minced garlic, 2 tbsp Shaoxing wine, 3 tbsp hoisin sauce, 2 tbsp oyster sauce, 1 tbsp soy sauce, 2 tbsp sugar, 1 tbsp cornstarch, 1/2 cup water, and 1 tsp sesame oil.
- Make the Dough
In a large bowl, whisk together the flour, sugar, yeast, and baking powder. Make a well in the center and pour in the lukewarm milk and oil. Mix until a shaggy dough forms, then turn out onto a floured surface. Knead vigorously for 8-10 minutes until smooth, elastic, and slightly tacky. Place in an oiled bowl, cover, and let rise in a warm place for 1 hour, or until doubled in size.
- Create the Filling
Heat 1 tbsp oil in a wok or skillet over medium heat. Add garlic and cook until fragrant, about 30 seconds. Add the diced char siu and stir-fry for 2 minutes. Pour in the Shaoxing wine and let it simmer for a moment. Add hoisin, oyster sauce, soy sauce, and sugar, stirring to coat the pork. Whisk cornstarch into the 1/2 cup water and pour into the pan. Cook, stirring constantly, until the sauce thickens into a glossy glaze, about 2-3 minutes. Stir in sesame oil, then transfer to a bowl to cool completely.
- Shape and Fill the Buns
Punch down the risen dough and divide into 10 equal pieces. Roll each piece into a ball, then flatten into a 4-inch circle with slightly thicker center. Place 1.5 tbsp of cooled filling in the center. Pleat and pinch the edges together tightly to seal, then place seam-side down on a small square of parchment paper. Arrange buns in a steamer basket, leaving space to expand. Cover and let proof for 30-45 minutes until puffy.
- Steam to Perfection
Bring water in your steamer base to a rolling boil. Carefully place the steamer basket with the proofed buns over the boiling water. Cover tightly. Steam on high heat for 12-15 minutes. DO NOT lift the lid during the first 10 minutes. After steaming, turn off the heat and let the buns sit for 2 minutes before gently lifting the lid to prevent condensation from dripping on them. Serve immediately.

There’s a particular, soul-stirring joy that only comes when the steamer lid lifts, revealing a tray of fluffy, perfectly domed char siu bao. That fragrant puff of sweet, savory steam is the very definition of culinary comfort. For years, I considered these barbecue pork buns a dim sum treat best left to the pros. Then I discovered that with a little patience and a whole lot of love, making this Chinese classic at home isn’t just possible—it’s profoundly satisfying. Let’s unlock the secrets to pillowy soft buns and a gloriously sticky filling.
The Story Behind the Perfect Char Siu Bao
While often synonymous with Cantonese yum cha, the story of stuffed buns like these stretches across Asia. This particular iteration, with its signature sweet-savory, ruby-hued barbecue pork, is a Hong Kong icon. It’s a brilliant example of “waste not, want not,” transforming leftover roast pork into a beloved new creation. The magic lies in the contrast: the soft, slightly chewy cloud of dough giving way to a rich, intensely flavorful center.
Why This Homemade Version Wins
What sets a truly great barbecue pork bun apart? First, the texture. The dough must be light-as-air yet sturdy enough to cradle its saucy cargo without getting soggy. Our recipe uses a combination of yeast and a touch of baking powder for that signature, cloud-like fluffiness. Second, the sauce for the filling. It shouldn’t just coat the pork; it should be a glossy, sticky-sweet glaze with a deep, caramelized complexity that soaks subtly into the bun. It’s this balance that makes the best char siu bao recipe worth mastering.
The Secret to Fluffy Bao Dough
The key is in the kneading and the rise. You’re not just mixing ingredients; you’re developing the gluten structure that will trap steam and create those beautiful air pockets. I used to rush this, but giving the dough a full, undisturbed rest is non-negotiable for achieving that dim sum-quality chew.
The One Pro-Tip You Need
Here’s my game-changer: for the juiciest, most flavorful char siu pork bao buns, marinate your diced pork (store-bought char siu is fine!) in a portion of the sauce mixture for at least 30 minutes before cooking the filling. This allows the meat to deeply absorb all that sweet, salty, umami goodness, ensuring every bite bursts with flavor.
Serving & Pairing: Beyond the Bamboo Basket
While they’re stars on their own, these homemade pork buns shine in a spread. Serve them steaming hot with a side of simple pickled vegetables for a bright, vinegary crunch that cuts the richness. A pot of robust pu-erh or jasmine tea is the traditional, perfect partner. For a modern twist, try them with a crisp, hoppy IPA—the bitterness plays beautifully against the sweet pork.
Delicious Variations to Explore
The beauty of the basic steamed bun dough is its versatility. For a char siu bao baked version, brush the shaped buns with an egg wash and bake at 375°F until golden—a fantastic textural contrast. Craving a crispy pork belly bao? Swap the diced char siu for chunks of braised, then fried pork belly. For a vegetarian char siu bao or vegan pork bun alternative, king oyster mushrooms, shredded and roasted with the same sauce, make an incredibly meaty, satisfying filling. You can also explore other regional styles like Filipino chinese siopao or Japanese nikuman.
Make-Ahead & Storage Smarts
You can prepare both the dough and filling a day ahead; store them separately, covered, in the fridge. Let the dough come to room temperature before shaping. Uncooked buns freeze beautifully: arrange them on a parchment-lined tray until solid, then transfer to a bag. Steam from frozen, adding 5-7 extra minutes. Leftover steamed bbq pork buns keep for 2 days in the fridge. Re-steam gently for the best texture—the microwave will make them tough.
Frequently Asked Questions
Can I make the char siu bao dough gluten-free?
Yes! Use a reliable 1:1 gluten-free flour blend that contains xanthan gum. The texture will be slightly more delicate, but still delicious. Check out Serious Eats for more on gluten-free baking science.
My buns collapsed or didn’t puff up. What went wrong?
This usually points to old yeast or under-proofing. Ensure your yeast is fresh and active, and let the shaped buns proof until they look visibly puffed and feel light, about 30-45 minutes. Also, avoid lifting the steamer lid during the first 10 minutes of cooking.
What’s the difference between char siu bao and other pork buns?
While terms like hum bao or pork hum bao can be generic, “char siu bao” specifically denotes the filling of Chinese barbecue pork. Other versions might contain different meats, like in a pork belly bun, or be cooked differently, like pan fried pork buns shanghai style.
So, tie on your apron and clear some counter space. The process of making these steamed delights is a meditation, and the reward—a kitchen fragrant with steam and the proud sight of your own plump, perfect buns—is absolutely worth it.
