Bean Bun Recipe: Steamed Pork and Bean-Filled Dumplings With Chewy Wraps

This bean bun recipe transforms simple ingredients into delicate, chewy-wrapped dumplings that balance sweet and savory perfection. 💛 The secret lies in the dough's elasticity and the filling's harmony—whether you choose classic red bean paste or a pork-infused version.

I've perfected the technique after years of testing, ensuring every bite delivers that signature texture and flavor.

The process begins with a foolproof dough that's both tender and sturdy enough to hold fillings without tearing. Whether you prefer yeast-based or non-yeast versions, the key is proper kneading and resting.

Meanwhile, the filling—whether sweet, savory, or a mix—must be packed just right to create those iconic, bite-sized bundles that steam into golden, glossy buns.

What makes these buns special is their chewy yet tender exterior and the contrasting filling inside. The steaming process transforms the dough into a soft, slightly translucent wrap that clings to the filling, creating a satisfying contrast with every bite.

This recipe delivers restaurant-quality results at home, with minimal equipment and just the right amount of effort.

Perfect for breakfast, tea-time snacks, or festive gatherings, these buns are versatile enough to suit any occasion. Once you master the technique, you'll find yourself making them regularly—trust me, they're that good. Let's get started on creating these beloved treats!

The flour is your foundation—look for King Arthur or Gold Medal for best results. Unbleached all-purpose gives that signature tender bite. Butter should be cold (straight from the fridge) to prevent dough from getting too soft. For the red bean paste, Asian markets carry the best quality—avoid the canned versions with added sugar. If you can't find unsweetened, reduce the sugar in the dough slightly. Sesame seeds? Trader Joe's sells them pre-toasted, saving you time. The yeast is non-negotiable for that authentic texture—don't skip it.

No instant yeast? Active dry works at double the amount. Short on sesame seeds? Toasted poppy seeds give a similar crunch. The dough needs to be tender but sturdy—if it feels too sticky, add a splash more flour (but not too much, or they'll be tough). For the filling, vegetable shortening creates that signature chewy texture, but more butter works in a pinch. The baking powder is subtle but helps with that signature slight lift. And remember: the water should be room temp—cold water shocks the yeast, warm water activates it too fast.

Store dough wrapped in plastic for up to 2 days in the fridge. The filling keeps 5 days covered in the fridge, but make fresh for best results. For freezing, shape the buns and freeze on a tray before bagging—3 months max. Steamed buns reheat beautifully in a steamer for 2 minutes or microwave for 15 seconds. Pro tip: make extra dough and freeze it—thaw overnight in the fridge before using.

Step-by-step instructions for chewy bean buns

Here's how to make these pillowy, chewy bean buns with a perfect balance of sweet and savory.

In a large mixing bowl, combine the 3 cups all-purpose flour, 0.25 tsp instant yeast, 0.25 cup granulated sugar, 0.5 tsp salt, and 0.25 tsp baking powder. Whisk everything together until evenly distributed—this ensures your dough develops properly. Create a well in the center and add the 0.25 cup cold cubed unsalted butter and 0.25 cup vegetable shortening. Use your fingers to work the butter and shortening into the flour mixture until it resembles coarse crumbs.

Next, add the 0.5 cup warm whole milk and 0.5 cup room temperature water. Mix gently with a wooden spoon or your hands until a shaggy dough forms. The dough should be soft but not sticky—if it feels too dry, add 1 teaspoon of water at a time until it comes together. Knead the dough on a lightly floured surface for 5-7 minutes until smooth and elastic. The dough should feel slightly tacky but not wet, and it should spring back when pressed gently. Cover the dough with a damp towel and let it rest for 30 minutes at room temperature—this relaxation step prevents shrinking during shaping.

In a small bowl, mix the 1.5 cups red bean paste with 1 tablespoon vegetable oil until smooth and well combined. The oil helps keep the filling moist during steaming. Taste the filling and adjust the sweetness if needed—you want a balance between the natural sweetness of the beans and the dough's mild flavor. If the paste is too thick, add 1 teaspoon of water at a time until it reaches a spreadable consistency. Cover the bowl and let the filling sit at room temperature while you prepare the dough for shaping.

Here's the thing—this filling should be just thick enough to hold its shape when piped but still smooth enough to spread evenly. If it's too runny, your buns will leak filling during steaming. I like to test the consistency by piping a small amount onto parchment paper—if it holds its shape without dripping, it's ready to go.

Divide the rested dough into 12 equal pieces (about 2 ounces each) by cutting off portions with a kitchen scale or by eyeballing them. Roll each piece into a 6-inch long log about ½-inch thick. Take one log and press it gently in the center to create a 1-inch wide pocket—this is where the filling will go. Pipe or spoon 1 tablespoon of red bean filling into the pocket, then carefully pinch the edges together to seal completely. Roll the sealed bun gently in your hands to smooth out any seams and ensure an even shape.

Place the shaped buns on a lightly greased baking sheet, seam-side down, and cover with a damp towel. Let them rest for 15 minutes before steaming—this final rest ensures they hold their shape beautifully during cooking. If you're making these ahead, you can refrigerate the shaped buns for up to 12 hours, covered tightly with plastic wrap.

Set up a steamer by filling a large pot with 2 inches of water and bringing it to a rolling boil over high heat. Place a heatproof steaming rack or inverted colander in the pot, ensuring it doesn't touch the water. Arrange the buns on the rack in a single layer, leaving ½-inch space between each one for even steaming. Cover the pot with a tight-fitting lid and steam for 15-18 minutes until the buns are plump, golden brown, and slightly puffed.

You'll know they're done when the bottoms are golden and the tops have a slight sheen—this indicates the steam has fully cooked the dough. Be careful not to oversteam, or the buns will become dense. Transfer the buns to a wire rack to cool for 5 minutes before serving. For extra flavor, sprinkle with 1 tablespoon toasted sesame seeds right after steaming while they're still warm.

These chewy bean buns are best served warm, straight from the steamer. The contrast between the soft, pillowy exterior and the sweet, smooth red bean filling makes every bite irresistible. I like to pair them with a cup of jasmine tea or hot milk for the full experience. If you're making them ahead, you can reheat them in a steamer for 5 minutes to restore their soft texture—just don't microwave them, or they'll turn rubbery.

Real talk: the first time I made these, I oversteamed them and ended up with dense, cake-like buns. Now I set a timer and watch for that golden color—it's the only way to guarantee that perfect chewy texture. Store any leftovers in an airtight container at room temperature for 2 days or refrigerate for up to 5 days. To reheat, steam for 3-4 minutes until warm and fluffy again.

Essential equipment for this recipe

Steamer Essentials

You don't need anything fancy—a large pot with a tight-fitting lid and a steaming rack or colander are all you need. I use a 12-inch stainless steel pot (like All-Clad) for even heat distribution.

For the rack, a heatproof bamboo steamer (available at Asian grocery stores) works perfectly, but any inverted colander or rack that fits snugly inside your pot will do. 🔥

Dough Tools

A rolling pin is helpful for shaping the dough logs, but your hands work just fine too. I prefer a wooden pin (like OXO Good Grips) for better control. For dividing the dough, a bench scraper or sharp knife works best.

A kitchen scale is ideal for measuring equal portions, but if you don't have one, eyeball 2-ounce balls (about the size of a golf ball).

Filling Prep

A small mixing bowl and silicon spatula are perfect for combining the red bean paste with oil. For filling the buns, a piping bag with a small round tip (or even a spoon) works well.

If you're making savory fillings, a small saucepan is useful for cooking meat or vegetables. I keep a fine-mesh strainer handy to drain any excess liquid from fillings like minced pork or mushrooms.

Optional Extras

For that golden finish, a pastry brush lets you lightly brush the buns with water before steaming. A small bowl of water nearby helps keep your workspace damp while shaping. If you want to toast sesame seeds, a small skillet or even a toaster oven works.

I also recommend keeping a timer handy—these buns steam quickly, and oversteaming ruins the texture. ⏱️

Budget-Friendly Swaps

No steamer rack? Use a clean towel folded into a square—just make sure it doesn't touch the water. For a rolling pin, a clean wine bottle wrapped in plastic works in a pinch.

Instead of a piping bag, a ziplock bag with a corner snipped off makes a great improvised tool. The key is keeping your tools clean and dry between uses to prevent sticking.
