What better way is there to celebrate Lunar New Year than with some baked Sourdough Red Bean Buns? Of course, I had to make Red Bean Buns with only sourdough as the leavening agent…because I love a challenge. And don’t worry, the buns don’t have any sour flavor from the sourdough. They’re super delicious.
I’m quite obsessed with red bean paste. I grew up eating red bean anything whenever I could get my hands on it. I would convince my mom whenever we were in Chinatown to take me into the bakeries just so I could get a million red bean items. And then of course, we’d go in and I would be too shy to tell the bakery staff what I wanted in Chinese.
To this day, my mom brings me anything red bean, sweet zongzi, steamed red bean buns, moon cakes, baked red bean buns…whatever she finds. I’ll always be a die-hard red bean fan. Red bean over green tea all day, every day. Fight me. Both together, though? I’m in heaven.
Now, these are actually way simpler than you think. The stand mixer mixes the dough for you the night before, and it rises on its own at room temperature overnight. You’ll make the red bean paste the night before as well and let it hang out in the fridge overnight. You also don’t even have to make the adzuki beans from scratch! Feel free to use canned adzuki beans if you can find them. I’ll be honest…I use canned beans all the time.
Sourdough Red Bean Buns: the easy breezy timeline:
The night before:
- Mix the dough & make the red bean paste.
- Set the covered dough on the counter & the red bean paste in the fridge when cool.
The morning:
- Shape the buns & set to proof at room temperature.
- Bake the buns!
- Consume happily.

Sourdough Red Bean Buns
Equipment
- 1 baking sheet
Ingredients
for the bun dough
- 400 mL canned coconut milk (shake the can before you open it!)
- 50g sourdough starter
- 55g sugar
- 350g bread flour
- 200g all-purpose flour
- ½ teaspoon salt
for the red bean paste
- 850g cooked and drained adzuki beans
- 140g brown sugar
for the egg wash/topping
- 1 egg (use plant-based milk for wash if making this recipe vegan and omit the water)
- 1 teaspoon water
- 1 tablespoon sesame seeds (white or black!)
Instructions
the night before
- In the bowl of a stand mixer, combine the coconut milk, starter, and sugar with a fork until mostly broken up. Then add the flour and salt and mix at low speed with a dough hook until fully combined and the dough is soft and formed (about five minutes).
- Remove the dough from the bowl and oil the bowl. Casually ball the dough and place back in the bowl. Cover and let rise overnight (12-14 hours).
- Now, make the red bean paste. Place the beans in a small saucepan with the brown sugar. Stir over low-medium heat until the paste is dry and mushy (about 10 minutes). You can smash the beans a little while cooking with the back of a spatula or a fork after cooking (if you wish!). Place the bean paste in a container and let cool completely. Then cover and place in the fridge overnight.
in the morning
- Your bun dough should now be fully risen!
- Dump out your dough and equally separate it (preferably by weight) into 8 balls on a lightly floured surface.
- Separate your red bean paste into 8 equal parts as well (you can eyeball it!) and with oiled palms, ball up the bean paste. (Note on the picture: Your bean paste balls will be much larger than these balls.)
- With your fingertips or a small rolling pin, press the dough into wide pancake, almost the size of your hand.
- Place a ball of red bean paste into the center of your dough pancake.
- Pinch the edges into the center to wrap up the bean ball.
- Keep pinching until the dough is fully level.
- Place the seam side down on a surface and gently twist it on the surface to ensure a full sealing on the seam. Repeat with the rest of your buns, setting them on a lined baking sheet for proofing.
- Cover and proof for 2.5 hours. They won’t look very different in size when done with proofing (the picture is them after proofing!). When almost done with the proof, preheat the oven to 350F.
- Make the egg wash by whisking together the egg and teaspoon of water, or if making this vegan, just use a small amount of plant-based milk. Brush the buns with the egg wash or milk and as you do each one, place a pinch of sesame seeds on top so they stick to the wash.
- Bake for 22-24 minutes. Let cool for 15 minutes before eating. Enjoy warm! Let me know what you think below in the comments or on Instagram @higheralchemybaking!

These rolls were so fun to make!
The buns were easy to handle and I had a great time playing around with filling options ☺.
I pressure-cooked my adzuki beans for the red bean filling (unsoaked, high for 23 min, 15 min natural release) and also experimented with a "char-siu"-like variety with fantastic results!
Hanna
Yay, Sasha! I'm so happy you enjoyed them.
Kaitlyn
Wow. That's all I got. Wow. These are unreal and so tasty. I made mine vegan and they are unbelievably good!! I love red bean paste too so they're just heavenly. Thank you so much for this recipe! ❤️
Hanna
Aw, thanks Kaitlyn! I'm so happy you enjoyed the recipe. Sorry for my late response as I've been traveling, but this comment makes my whole day!
Ann
What is the temperature of the oven? Thank you.
Hanna
350F!
Aleca
I’m having fun making these, have not finished yet (waiting for buns to rise currently)
BUT I ended up with WAY more bean paste than needed starting with 850g of beans. Did I read that wrong?
Hanna
That is a correct starting amount, but should end up losing so much water that the final bean paste is much, much less. I should update this recipe to have a final amount of bean paste in grams. Sorry about that!
Bear
Hi! These look fantastic and I can't wait to try them out with my toddler. Could you please let me know if the buns are soft or crusty? Thanks!
Hanna
Hi there! That sounds like a lovely time. These buns are very soft!
