Buttery Croissant Sourdough Loaf
I think I just made the best bread I’ve ever baked… and I’m genuinely struggling not to eat the entire loaf while it cools
This Croissant Sourdough Loaf is what happens when flaky croissants and tangy sourdough decide to show off together. Crispy golden edges, buttery layers, soft airy crumb, and pockets of melted butter in every slice. It’s rich, dramatic, messy, and absolutely worth it.
And yes… that’s real butter in there. No shortcuts today
Ingredients
Dough
500g bread flour
340g water
120g active sourdough starter
12g salt
Butter Layers
1 stick unsalted butter, frozen and grated
Optional Additions
Flaky sea salt on top
Honey drizzle after baking
Fresh rosemary or thyme
Shredded parmesan
Everything bagel seasoning
Instructions
1. Mix the Dough
In a large bowl, combine the water and sourdough starter until mostly dissolved. Add the bread flour and salt. Mix until a shaggy dough forms. Cover and let rest for 30 minutes.
2. Stretch & Fold Process
Perform 4 sets of stretch and folds every 30 minutes.
During the 2nd fold, gently work in half of the frozen grated butter.
During the 3rd fold, add the remaining butter.
Keep the dough cool so the butter stays solid instead of melting into the dough. That’s the secret to those flaky croissant-like layers.
3. Bulk Fermentation
Cover the dough and let it rise until roughly 75% larger in size. Depending on room temperature, this can take 4–7 hours.
4. Shape the Loaf
Turn the dough onto a lightly floured surface and shape gently without pressing out all the air. Place into a banneton or towel-lined bowl seam-side up.
5. Cold Proof Overnight
Refrigerate overnight for maximum flavor and structure.
6. Bake
Preheat oven to 450°F (230°C).
Place the dough into a loaf pan and cover with a second loaf pan or oven-safe cover.
Bake:
30 minutes covered at 450°F
Then uncover and bake 20–25 minutes at 425°F until deeply golden and crispy.
7. Cool Before Slicing
This is the hardest part. Let the loaf cool completely before slicing so the buttery layers can set properly.
Tips for Success
Freeze the butter beforehand for easy grating.
Cold dough creates better flaky layers.
Don’t overwork the dough after adding butter.
Place a baking tray underneath your loaf pan
because butter may drip while baking.
Use strong bread flour for the best structure and chew.
Description
The crust bakes up deeply golden and crisp while the inside stays soft, stretchy, and layered with buttery richness. Every slice smells like a French bakery collided with an artisan sourdough shop. Toast it once and you may never buy bread again.

Embracing Healthful Indulgence
This loaf celebrates balance and craftsmanship. While rich and buttery, it’s also naturally fermented through sourdough, which many people find easier to digest and more flavorful
than conventional bread. Enjoying homemade artisan baking is about slowing down, savoring quality ingredients, and appreciating food made with care.
FAIR WARNING: Your kitchen will smell like absolute heaven… and once people taste it, they’ll demand you bake it again
