Substitutions & Variations
- You can use bread flour for a better structure, but it will cost you a bit of softness.

- For a softer crust, brush the loaf with milk or cream before baking.
- Want a slightly richer loaf? Add a tablespoon of butter during mixing.
How to Make Lazy Sourdough Tangzhong Sandwich Bread
Step 1: Add 200 g flour to a bowl and pour over 300 g boiling milk (Image 1). Stir well until smooth and thick. Let the lazy "tangzhong" cool to room temperature.
Step 2: Once cooled, add the sourdough starter, sugar, remaining milk (150 g), and remaining flour (300 g) (Image 2).
Step 3: Mix until a rough dough forms, about 3 minutes. Making a smooth dough isn't the goal here; it's just to mix all the ingredients together.
Step 4: Transfer the dough to a bowl where you plan to keep it while it ferments (this can also be the bowl of a stand mixer, if you wish). Cover and let the dough rest for about 30 minutes (Image 4).
Add the salt and heavy cream. Knead and squeeze slowly until the dough becomes smooth and soft. This dough will be quite sloppy, but manageable.
Step 5: Over the next 2 hours, perform 3 sets of stretch and folds (Image 5), spaced about 30 minutes apart.
Step 6: After the final fold, let the dough rest and ferment in the bowl (Image 6). This should take about 4-6 hours, depending on your kitchen temperature and starter strength. Start counting the bulk fermentation from the moment you add the starter to the dough.
Step 7: Turn the dough out onto the counter and gently stretch it into a rectangle (Image 7) roughly the length of your loaf pan.
Step 8: Roll it up tightly (Image 8).
Step 9: Place the dough seam-side down into a greased sandwich loaf pan (Image 9).
Step 10: Cover and let rise for another 3-4 hours, until the dough rises just above the rim of the pan (Image 10).
Step 11: Preheat the oven to 180°C (355°F). If using, brush the loaf with heavy cream for a softer, shinier crust.
Bake for 30 minutes at 180°C (355°F), then lower the temperature to 150°C (300°F) and bake for another 20 minutes (Image 11).
Step 12: Remove from the pan and let cool completely before slicing (Image 12).
Hint: If your dough feels a bit loose during mixing, resist the urge to add extra flour right away. This dough tightens up naturally as fermentation progresses and the tangzhong continues to hydrate the flour.
Baking Schedule
- Make tangzhong and dough: Morning
- Stretch and folds: First 2 hours
- Bulk fermentation: 4-6 hours
- Shape and pan: Late afternoon
- Final rise: 3-4 hours
- Bake: Evening
As you can see, this is a relaxed, same-day bake with plenty of flexibility.
💭Crucial Success Tips
Be gentle during shaping. You're not trying to knock out all the air, just organize the dough into a tight roll so it rises evenly in the pan. And finally, let the loaf cool completely before slicing. Cutting too early can compress the crumb and make the bread feel gummy, even if it's fully baked.
Recipe FAQs
This sandwich bread works best with an active, bubbly starter. An unfed or sluggish starter can slow fermentation and lead to a dense loaf. If your starter hasn't peaked yet, it's better to wait a few hours before mixing the dough.
AnswerLazy sourdough tangzhong sandwich bread dough is naturally sticky because of the high hydration and tangzhong method. This is normal and intentional. The dough becomes smoother and easier to handle as fermentation progresses and the gluten develops.
How To Store Lazy Sourdough Tangzhong Sandwich Bread
Once completely cooled, store the bread in an airtight container or bread bag at room temperature for up to 3 days. For longer storage, slice the loaf and freeze it. Toast slices straight from the freezer as needed.

Lazy Sourdough Tangzhong Sandwich Bread
Ingredients
Tangzhong
- 200 g all-purpose flour
- 300 g milk boiling
Dough
- 300 g all-purpose flour
- 150 g milk cold or room temperature
- 260 g active sourdough starter
- 60 g heavy cream
- 15 g salt
- 8 g sugar
- 1 tablespoon heavy cream
Instructions
- Add 200 g flour to a bowl and pour over 300 g boiling milk. Stir well until smooth and thick. Let the lazy "tangzhong" cool to room temperature.
- Once cooled, add the sourdough starter, sugar, remaining milk (150 g), and remaining flour (300 g).
- Mix until a rough dough forms, about 3 minutes. Making a smooth dough isn't the goal here; it's just to mix all the ingredients together.
- Transfer the dough to a bowl where you plan to keep it while it ferments (this can also be the bowl of a stand mixer, if you wish). Cover and let the dough rest for about 30 minutes. Add the salt and heavy cream. Knead and squeeze slowly until the dough becomes smooth and soft. This dough will be quite sloppy, but manageable.
- Over the next 2 hours, perform 3 sets of stretch and folds, spaced about 30 minutes apart.
- After the final fold, let the dough rest and ferment in the bowl. This should take about 4-6 hours, depending on your kitchen temperature and starter strength. Start counting the bulk fermentation from the moment you add the starter to the dough.
- Turn the dough out onto the counter and gently stretch it into a rectangle roughly the length of your loaf pan.
- Roll it up tightly.
- Place the dough seam-side down into a greased sandwich loaf pan.
- Cover and let rise for another 3-4 hours, until the dough rises just above the rim of the pan.
- Preheat the oven to 180°C (355°F). If using, brush the loaf with heavy cream for a softer, shinier crust. Bake for 30 minutes at 180°C (355°F), then lower the temperature to 150°C (300°F) and bake for another 20 minutes.
- Remove from the pan and let cool completely before slicing.
Notes
- No need to stress too much about the timing of stretch and folds. You can do all 3 sets anytime during the first 2 hours of the first rise, as long as they're at least 15 minutes apart so the dough has time to relax.
- Be gentle during stretch and folds. Try not to tear the dough, even if that means you don't stretch it very far.
- This makes a very soft, light sandwich bread that's perfect for toast.
- Especially good with cheese and/or salami, toasted until crisp on the outside and soft inside.
- The tangzhong helps keep this loaf tender for days without making it dense.
