This loaf is a hybrid between traditional sourdough and classic croissants. You get the depth, tang, and chew of sourdough alongside laminated, buttery layers reminiscent of a croissant. It takes patience, planning, and care, but the result is a show-stopping loaf with feathery crumb, crisp crust, and incredible flavor.
This recipe spans two days, with rest and refrigeration periods that let the dough develop flavor and structure naturally. It’s not a fast bread—but it’s worth the effort.
Ingredients
Dough
- 450 g bread flour (strong, 11.5–13% protein)
- 50 g all-purpose flour
- 350 g water (room temperature)
- 100 g active sourdough starter (100% hydration)
- 10 g fine sea salt
- 20 g sugar or honey (optional, for a slightly sweet, croissant-like flavor)
Lamination
- 200 g high-quality unsalted butter, cold but pliable
Equipment
- Large mixing bowl
- Dough scraper
- Rolling pin
- Parchment paper
- Bench knife
- Plastic wrap or reusable cover
- Dutch oven or lidded bread pot
- Baking stone or steel (optional)
Day 1 – Dough Development and Lamination
1. Autolyse (45–60 Minutes)
- In a large bowl, combine bread flour, all-purpose flour, and water.
- Mix until no dry flour remains. Dough will look shaggy and rough.
- Cover and rest 45–60 minutes.
Why it matters: Autolyse hydrates the flour and starts gluten development without kneading. This step makes lamination smoother and prevents tearing.
2. Incorporate Starter, Salt, and Sugar
- Add the sourdough starter, salt, and sugar to the autolysed dough.
- Mix by hand, squeezing and folding until the dough is cohesive. Expect stickiness.
- Rest 20 minutes.
3. Stretch-and-Folds (Bulk Begins)
Over the next 2 hours, perform four stretch-and-fold sets every 30 minutes:
- Grab one edge of the dough.
- Stretch upward gently.
- Fold it over itself.
- Rotate the bowl and repeat 3–4 times.
By the final fold, the dough should feel smooth, elastic, and stronger.
4. Prepare the Butter Block
- Place butter between parchment sheets.
- Roll into a 20 × 20 cm (8 × 8 inch) square.
- Keep edges straight; if too soft, chill briefly.
Tip: Butter and dough should have similar firmness when laminating—cold but pliable.
5. Lamination Process – Enclose Butter
- Roll dough into a 30 × 30 cm (12 × 12 inch) square on a lightly floured surface.
- Place butter in the center at a diamond angle.
- Fold the corners of dough over the butter like an envelope, sealing completely. Pinch seams gently.
6. First Fold (Single Fold)
- Roll dough into a rectangle about 20 × 60 cm (8 × 24 inches).
- Fold like a letter: top third down, bottom third up over it.
- Wrap and refrigerate 30 minutes.
7. Second Fold
- Rotate dough 90°.
- Roll into long rectangle, repeat the same single fold.
- Refrigerate 30–45 minutes.
Optional: A third fold adds extra layers but increases risk of butter melting or tearing. Two folds already produce beautiful lamination.
8. Bulk Fermentation
Let the laminated dough rest at room temperature until ~50% volume increase (2–3 hours).
The dough should feel puffy, airy, and alive—but not overly soft or jiggly.
Day 2 – Shaping, Proofing, and Baking
9. Cold Proof Overnight
- Pre-shape dough into a loose round; rest uncovered 20 minutes.
- Final shape into boule or batard, careful not to degas.
- Place seam-side up in a floured banneton or towel-lined bowl.
- Cover and refrigerate 8–14 hours.
10. Preheat Oven
- Preheat to 250°C / 480°F with a Dutch oven inside for at least 45 minutes.
Tip: Cold dough into a very hot oven creates excellent oven spring.
11. Score and Bake
- Remove dough from fridge and turn onto parchment.
- Score confidently with a sharp blade; one deep slash works well.
- Bake in Dutch oven:
- 20 minutes covered
- Reduce temperature to 230°C / 450°F, bake uncovered 20–25 minutes
- Internal temperature: ~96–98°C (205–208°F)
12. Cooling
- Cool on a wire rack for at least 2 hours before slicing.
- Cutting too early compresses layers; cooling sets the crumb and flakiness.
What to Expect
- Crust: Deeply caramelized, crisp, slightly blistered
- Crumb: Open, feathery, with visible butter layers
- Flavor: Tangy from sourdough, rich and buttery, subtly sweet
- Serving ideas:
- With salted butter or flaky salt
- Toasted with honey or jam
- Topped with soft cheese or smoked salmon
- Simply plain and admired
Tips for Success
- If butter leaks, don’t worry—it still tastes amazing.
- Keep dough and butter cool during lamination; chill whenever dough feels greasy.
- Use high-fat European-style butter for best flavor.
- Once baked and cooled, this bread freezes well.
This Croissant Sourdough Loaf combines patience, lamination, and natural fermentation into a luxurious loaf that slices beautifully and delivers bakery-level flavor at home.
