How to Make Croissant Sourdough Loaf
Step 1: Mix the Dough
In a large bowl, combine:
- Bread flour
- Water
- Active sourdough starter
- Sugar
Mix until shaggy.
Allow the dough to rest for:
30 minutes
This process is called autolyse.
Step 2: Add Salt and Butter
Add:
- Salt
- Softened butter
Knead until smooth and elastic.
Step 3: Bulk Fermentation
Place dough into a lightly greased bowl.
Ferment at room temperature for:
- 4–6 hours
Perform stretch and folds every 30 minutes during the first 2 hours.
Step 4: Prepare the Butter Block
Place cold butter between parchment paper.
Roll into a flat rectangle.
Chill until firm but pliable.
Step 5: Laminate the Dough
Roll dough into a large rectangle.
Place the butter block in the center.
Fold dough over the butter like an envelope.
Roll and fold the dough into thirds.
Chill for:
30 minutes
Repeat rolling and folding process 3 times total.
This creates the flaky layers.
Step 6: Overnight Refrigeration
Wrap the dough tightly and refrigerate overnight.
Long cold fermentation improves flavor and texture.
Step 7: Shape the Loaf
Roll the dough gently into a rectangle.
Tightly roll into a loaf shape.
Transfer into a greased loaf pan.
Step 8: Final Proof
Allow the loaf to rise until puffy and airy.
Proofing usually takes:
- 2–4 hours
depending on room temperature.
Step 9: Preheat the Oven
Preheat oven to:
375∘F≈190∘C
Brush the loaf lightly with egg wash if desired.
Step 10: Bake the Loaf
Bake for:
- 40–50 minutes
until deeply golden brown and crisp.
Best Internal Temperature for Sourdough Loaf
Fully baked laminated sourdough bread reaches:
205∘F≈96∘C
Use a thermometer for best accuracy.
Step 11: Cool Before Slicing
Allow the loaf to cool for at least:
1 hour
before slicing.
Cooling helps preserve flaky layers.
Tips for Perfect Croissant Sourdough Loaf
