This bean paste bun recipe transforms simple dough into crispy, golden crowns filled with velvety red bean paste—a perfect balance of textures and flavors. The secret lies in the dough's elasticity and the precise steaming technique that creates that signature crispy exterior while keeping the filling tender.
I've perfected this method over years of testing, ensuring every bite delivers that satisfying contrast between the crispy tortilla shell and creamy bean heart.
The dough requires just five basic ingredients—flour, yeast, sugar, salt, and water—mixed to a smooth, slightly sticky consistency that's easy to work with. For the filling, I recommend using high-quality store-bought red bean paste for convenience, though homemade versions add deeper flavor.
The shaping technique is what elevates these buns from ordinary to extraordinary, with pleated edges that create those iconic crown shapes.
What you'll end up with are golden-brown buns with perfectly crispy exteriors that shatter slightly when bitten, revealing the creamy, slightly sweet bean paste inside. The aroma alone—warm, fragrant, and just slightly sweet—will have everyone gathering around your kitchen.
These buns are ideal for snacking, pairing with tea, or serving as part of a larger Asian-inspired spread.
This recipe delivers restaurant-quality results at home with minimal effort. The key is patience during both the dough rising and the steaming process—rushing either step will compromise that perfect crispy texture. Once mastered, you'll find yourself making these buns regularly for their addictive combination of textures and flavors.
Ingredients for bean paste bun
Five simple dough ingredients plus premium fillings create these iconic crispy-tender buns.
| Ingredient | Amount | Notes |
|---|---|---|
| All-Purpose Flour 🌾 | 4 cups | High-protein for elasticity (11-12% protein) |
| Active Dry Yeast 🍞 | ¼ oz | Or 2.5g, fresh if available |
| Granulated Sugar 🍚 | ½ cup | Feeds yeast for proper rise |
| Kosher Salt 🧂 | 1 ½ tsp | Diamond Crystal preferred |
| Warm Water 💧 | 1 ¼ cups | 110°F (43°C) for yeast activation |
| Vegetable Oil 🫒 | 2 tbsp | For dough handling ease |
| Red Bean Paste 🌱 | 2 cups | High-quality store-bought or homemade |
| Sesame Seeds 🌻 | ¼ cup | Toasted for enhanced aroma |
| Cornstarch 🌽 | 1 tbsp | For dusting pleated edges |
| Vegetable Shortening 🧈 | 1 tbsp | For crispy exterior (optional) |
The flour is non-negotiable—King Arthur or Bread Flour with 11-12% protein delivers that signature elasticity. Active dry yeast should be tested first (proof in warm water with sugar), and Diamond Crystal kosher salt dissolves more cleanly than table salt. Water temperature matters: too hot kills yeast, too cold slows activation. For the filling, Japanese or Chinese red bean paste brands like Haein or Fuqi are ideal, but any smooth, sweetened paste works. Toast the sesame seeds in a dry pan until golden for maximum aroma impact—30 seconds is perfect.
No sesame seeds? Toasted poppy seeds or white sesame work as substitutes, though flavor differs. The bean paste can be homemade (simmer azuki beans with sugar until thick), but store-bought saves time. For extra crispiness, brush the shaped buns with melted vegetable shortening before steaming. The dough's stickiness is intentional—add flour only if absolutely necessary during shaping. If your kitchen is humid, reduce water by 1 tbsp to prevent over-sticky dough.
Freshly mixed dough keeps 24 hours refrigerated wrapped in plastic, but best results come from using it immediately. The bean paste filling can be prepped 3 days ahead and stored airtight in the fridge. For reheating, steam for 5-8 minutes to restore crispiness. These buns freeze beautifully—shape them, freeze on a tray, then transfer to a bag for up to 3 months. Thaw at room temperature before steaming.

Step-by-step instructions for bean paste buns
Mastering these buns requires precision in dough handling and filling technique—here's how to achieve that perfect balance of crispy tortilla crowns and creamy red bean filling.
Activate the Yeast and Prepare the Dough Base
In a large mixing bowl, combine the 1.25 cups warm water (tested at 110°F) with the 0.5 cup granulated sugar and 0.25 oz active dry yeast. Let this mixture sit for 5-7 minutes until it becomes frothy and bubbles form on the surface—this confirms the yeast is active. If it doesn't bubble within this time, your yeast may be stale.
Add the 4 cups all-purpose flour and 1.5 tsp kosher salt to the bowl. Using a dough hook attachment on a stand mixer, mix on low speed for 2 minutes until combined. Gradually add the 2 tbsp vegetable oil and 1 tbsp vegetable shortening, mixing until fully incorporated. The dough should begin to pull away from the sides of the bowl and form a shaggy mass.
Knead the Dough to Develop Gluten
Increase the mixer speed to medium and knead the dough for 5-7 minutes until it becomes smooth, elastic, and passes the windowpane test—press a small piece between your fingers, then pull apart; if it stretches thin without tearing, the gluten is properly developed. If the dough feels too sticky, add 1 tbsp flour at a time until it reaches a pliable but not sticky consistency.
Transfer the dough to a lightly oiled bowl, cover with a damp kitchen towel, and let it rest at room temperature for 30 minutes. This brief rest relaxes the gluten structure, making it easier to handle when we shape the buns later. The dough should nearly double in size during this time, though it won't rise dramatically like bread dough.
Assemble the Buns with Bean Paste Filling
Preheat your oven to 375°F and line two baking sheets with parchment paper. Divide the rested dough into 12 equal portions (about 2 oz each) and roll each piece into a 6-inch circle using a rolling pin. Keep the remaining dough covered to prevent drying.
Place 2 tbsp red bean paste in the center of each dough circle, leaving a 1-inch border around the edges. Fold the dough over the filling to create a half-moon shape, then pleat the edges by pinching the dough at ½-inch intervals along the border. Brush the pleated edges with water and dust with 1 tbsp cornstarch to create crispy, decorative pleats. Sprinkle each bun with 1 tsp sesame seeds for texture and aroma.
Proof and Bake for Crispy Exteriors
Transfer the assembled buns to the prepared baking sheets and let them proof at room temperature for 20-25 minutes until they've risen slightly and the pleats look defined. This proofing step is crucial—it ensures the buns expand slightly in the oven for a lighter texture.
Bake for 18-22 minutes until the bottoms are deep golden brown and the tops are puffed. Rotate the baking sheets halfway through for even browning. The buns should sound hollow when tapped on the bottom—a sure sign of a crispy exterior. Remove from the oven and let cool for 5 minutes before serving to allow the filling to set slightly.
Pro Tips For Making Bean Paste Bun
- STRETCH THE DOUGH: I learned this the hard way—bean paste buns need a long fermentation, but most people underestimate how much the dough resists. After the first rise, slap it down, fold it into thirds (like a letter), and let it rest for 10 minutes before shaping. This builds gluten and prevents dense, chewy buns.
- SALT THE WATER: Skip the salt in the dough water? Big mistake. Dissolve that ½ teaspoon kosher salt right in the warm water before mixing—it kickstarts yeast activity and balances the sweetness of the bean paste later. (Yes, even if the recipe says "optional.")
- CHILL THE SHAPED BUNS: I used to bake them straight from shaping, and they’d puff up unevenly, often cracking. Instead, pop shaped buns on a tray, cover with a damp towel, and refrigerate for 30 minutes. The cold slows yeast, keeps them from overproofing, and guarantees a clean rise.
- USE A DAMP TOWEL: The bean paste filling is sticky, and dry hands = a mess. Keep a damp kitchen towel handy when shaping—dip your fingers in water before sealing the buns. It helps the dough stick together without making it gummy, and you’ll save hours of cleanup.

Frequently asked questions
Can I make these bean paste buns without a stand mixer?
The dough can be mixed by hand in a large bowl using a wooden spoon, then kneaded on a lightly floured surface for 8-10 minutes until smooth and elastic. Work in a well-floured environment to prevent sticking, and knead vigorously to develop the gluten properly. The windowpane test (stretching a small piece thin without tearing) confirms readiness.
What if my dough doesn't rise properly?
Check your yeast first—it should bubble within 5-7 minutes in warm water with sugar. If not, replace it. Also ensure your water is 110°F (43°C) (not too hot or cold) and your kitchen is 70-75°F (21-24°C). For better rise, place the dough in a warm oven with a bowl of boiling water for 15 minutes during proofing. Cold weather? Extend proofing to 45-60 minutes.
How do I get the pleats to look crispy and professional?
Brush the pleated edges with water, then dust generously with cornstarch before baking. The starch creates that signature crispy texture. For cleaner pleats, use a small fork to create ¼-inch deep pleats at ½-inch intervals before brushing with water. Bake at 375°F (190°C) until golden brown—this high heat is key for crispiness.
Can I make these buns ahead of time?
Yes! Shape the buns and freeze them on a tray before final proofing. Transfer to a freezer bag for up to 3 months. To serve, thaw at room temperature for 30 minutes, then steam for 5-8 minutes to restore crispiness. For storage, keep baked buns in an airtight container at room temperature for 2 days or refrigerate for 5 days—reheat in a 350°F (175°C) oven for 3-5 minutes.
What's the best way to reheat these buns?
For maximum crispiness, steam reheated buns for 3-5 minutes over boiling water. Place them on a wire rack over a pot with 1 inch of water. Alternatively, warm in a 350°F (175°C) oven for 3-4 minutes on a wire rack (not directly on the pan). Microwaving works in a pinch but makes them soggy—avoid if possible!
