A Zesty Leftover Rescue
I stumbled upon a container of Greek yogurt in my fridge that had seen better days—not bad enough to waste, but not quite breakfast-worthy either. That’s when inspiration struck: what if I baked Yogurt Lemon Poppy Seed Sourdough Soft Buns? The result was nothing short of magical—airy, citrusy, and impossibly soft, with a delightful poppy crunch in every bite.
Why You’ll Love It
-
Light tang meets citrus zing – Greek yogurt and lemon zest combine for an irresistible, aromatic tang.
-
Delicate softness – The sweet stiff starter yields buns that are pillow-like and tender.
-
Texture harmony – Nutty poppy seeds punctuate the loaf with delightful contrast.
-
Unique flavor union – A sophisticated match of sourdough tradition with bright, fresh flavors.
How To Make Yogurt Lemon Poppy Seed Sourdough Soft Buns
Ingredients (Yields: 9 Buns)
Sweet Stiff Starter:
60g sourdough starter (100% Hydration), preferably use at its peak
180g bread flour (I used Japan High Gluten Flour)
85g milk or 75g water (I used full cream or whole milk)
30g sugar (I used organic brown sugar)
Main Dough:
140g bread flour (I used Japan High Gluten Flour)
All stiff starter (above)
15g light brown sugar, please increase or reduce accordingly to your liking.
1 1/4 tsp salt
45g egg, whisked (from 1 medium egg)
100g greek plain yogurt (reserve 10g and add in later if needed) I used total 100g
30g butter, room temperature
10g poppy seeds
Zest of 1 1/2 lemon
Egg Wash:
1 egg + 1 Tbsp milk
Utensil:
8" square pan
Note: If you use water to build the sweet stiff starter, you may want to add 15g of milk powder in the main dough to enhance the taste.
Step-By-Step Instruction
- Sweet Stiff Starter
- In a bowl of stand mixer, dilute starter with milk/water, stir in sugar and add in bread flour. Mix with paddle attachment until well mixed and all come together. It can be done by hand mixing too.
- Cover and let it ferment until tripled. I prepared a night before and leave it in aircond room (approximately 24 - 25C room temperature) overnight until tripled. It took about 9 - 10 hours depending on your starter. It should take around 5 - 6 hours to get triple at room temperature at 28C - 30C.
- Kneading Dough:
- Put all ingredients (except butter) into a bowl of stand mixer. I usually slightly torn the stiff starter dough first.
- Slightly combine the mixture by hand with the paddle attachment before turning on the machine so that the flour will not splash out. Using the paddle attachment, mix for 2 minutes or until all incorporated. This step is critical to prevent an uneven mixed dough as the stiff starter is rather hard and a dough hook may not be able to mix it well enough.
- Change to hook attachment and knead for another 3 minutes or until the dough comes together. Add in butter and continue knead for 10 - 12 minutes or until the dough become smooth, silky and reach window pane stage. The whole kneading process, I stopped few times to scrape down the dough from the hook to be sure it is evenly kneaded and also to prevent the motor from overheating.
- 1st Proofing/Resting:
- In the same bowl, let the dough rest for 45 minutes. Keep it covered with clingfilm or use a lid. The dough rose slightly in 45 minutes.
- Shaping:
- Transfer the dough to a clean surface then divide dough into 9 equal portions (approx. 79g each). Please use a kitchen scale if you want to be exact.
- Form each portion to a ball. Please watch the video here "How to shape bun"
- Place bun onto the baking pans lined with parchment paper.
- Final Proofing:
- Let the buns proof at a warm place until the dough rise double in size. This one took approximately 2.5 hours at at room temperature of 29C - 30C. The duration of proofing depends on your ambient temperature and the starter.
- Baking:
- Preheat oven at 190C (top & bottom heat) or 170C (fan-forced) for 10 - 15 minutes.
- Brush with egg wash.
- Bake in a preheated oven for 18 - 20 minutes, or until golden brown.
- Remove buns from oven and pan. Let them cool on rack.

Expert Tips for Success
-
Feed your starter ahead of time—a lively, bubbly starter ensures optimal rise and flavor.
-
Watch your dough’s feel—it should be smooth and elastic; reserve some yogurt to adjust hydration on the fly.
-
Use the windowpane test—if the dough stretches thin into a translucent sheet, gluten is well developed.
-
Go by feel, not time—proofing and kneading durations vary with temperature, flour, and equipment.
Common Mistakes & How to Avoid Them
-
Over-kneading the dough – Kneading too long can make the dough tough and difficult to shape. Stop once the dough passes the windowpane test and feels smooth.
-
Under-proofing – If the buns are baked before they’ve risen enough, they will turn out dense. Allow the dough to proof until it has risen 80–90% in volume, using the finger-poke test as a guide.
-
Over-proofing – Proofing too long causes the buns to collapse or wrinkle after baking. Bake as soon as they reach the right volume.
-
Incorrect hydration – Adding all the yogurt or liquid at once may make the dough too sticky. Always reserve some and adjust gradually.
-
Inactive or weak starter – A sluggish starter leads to poor rise and dense buns. Make sure your sweet stiff starter is fed and active before baking.
-
Uneven shaping – Poorly shaped dough balls can bake unevenly. Take time to create smooth, tight rounds for a uniform crumb and appearance.
-
Over-baking – Leaving the buns too long in the oven dries them out. Bake until golden brown and check doneness with a thermometer (internal temp around 90–93°C).
Tips for Shaping, Proofing & Baking
-
Divide precisely—use a scale to portion 9 equal buns (~79g each) for even baking.
-
Shape carefully—round into tight balls to develop surface tension; this encourages even rise.
-
Final proof—leave buns in an 8″ pan until nearly doubled. Touch test: indentation should gently spring back, leaving a faint mark.
-
Bake with care—preheat oven thoroughly (190 °C top/bottom or 170 °C fan). Brush with egg wash for glossy, golden crust. Bake 18–20 minutes or until evenly browned.
Ingredient Substitutions & Variations
-
Milk options—substitute whole milk with plant-based milk (adjust hydration if needed).
-
Sugar swaps—white or coconut sugar works—just tweak amount based on sweetness preference.
-
Add-ins—swap poppy seeds for sesame or chia seeds; add dried fruit or citrus zest of your choice.
-
Flavor shift—use lime zest instead of lemon, or stir in herbs like rosemary for savory versions.
Troubleshooting Guide
-
Buns turn out dense – Starter may be weak or dough was under-proofed. Make sure your sweet stiff starter is active and allow enough proofing time.
-
Dough is too sticky – Hydration is too high. Hold back some yogurt or flour until the dough feels manageable, then adjust gradually.
-
Wrinkled or collapsed tops after baking – Dough was over-proofed or oven not preheated properly. Bake once proofed 80–90% and ensure oven is fully heated.
-
Crumb is tough or chewy – Dough may have been over-kneaded. Stop kneading once the dough passes the windowpane test.
-
Unevenly shaped buns – Dough pieces were not scaled or rounded properly. Use a kitchen scale and roll into smooth, tight balls for even baking.
-
Dry texture inside – Over-baked or insufficient hydration. Reduce baking time slightly and check internal temperature (90–93°C).
-
Pale crust – Oven temperature too low or no egg wash applied. Preheat oven thoroughly and brush with egg wash before baking.
-
Sour flavor stronger than expected – Starter was left too long or over-fermented. Use the starter at peak activity for a milder flavor.
Serving Suggestions & Storage
-
Perfect with—a smear of lemon curd, berry jam, or a drizzle of honey.
-
Best enjoyed fresh—warm them in the oven briefly to revive softness.
-
Storage—keep in an airtight container for up to 2 days; freeze cooled buns wrapped in foil for up to 1 month.
