Unloaf Sourdough Bread: Rustic, Crusty, and Naturally Fermented

There’s something deeply satisfying about sourdough bread — the complex flavor, the chewy interior, and that glorious crust. But not everyone wants a tightly shaped sandwich loaf. Enter the “Unloaf” sourdough bread: a free-form, artisan-style sourdough baked without a loaf pan, giving you full freedom to embrace rustic edges, natural cracks, and a gorgeous golden crust.

This style of sourdough is perfect for beginners and purists alike. It requires fewer tools, no pan, and lets the dough speak for itself. The process relies on a natural sourdough starter and long fermentation to develop both flavor and texture. You’ll get a naturally tangy taste, open crumb, and thick crust — all without the need to “shape” the dough into a perfect loaf.

Whether you’re baking for your family, serving a dinner party, or just want to tear off a chunk of warm bread with soup, this Unloaf Sourdough is a celebration of traditional bread in its most honest, unfussy form.

🕒 Cooking Time & Yield

🥖 Ingredients for Unloaf Sourdough Bread

• 500g (about 4 cups) bread flour

• 375g (1 1/2 cups + 1 tbsp) water (room temperature)

• 100g (about 1/2 cup) active sourdough starter (fed and bubbly)

• 10g (2 tsp) fine sea salt

Optional additions:

• 1 tbsp olive oil (for a slightly softer crust)

• Herbs, garlic, olives, or seeds for flavor variation

🔪 How to Make Unloaf Sourdough Bread

Step 1: Mix the Dough

In a large bowl, combine the sourdough starter and water. Stir to dissolve. Add flour and mix until no dry bits remain — the dough will be shaggy. Cover with a damp towel and rest for 30–45 minutes (this is the autolyse stage).

Step 2: Add Salt

Sprinkle salt over the dough. With wet hands, knead or “pinch and fold” the salt into the dough until evenly distributed (about 2–3 minutes).

Step 3: Bulk Fermentation (First Rise)

Let the dough rise at room temperature for 6–8 hours, performing stretch and folds every 30 minutes during the first 2 hours. To do this, grab one side of the dough, stretch it upward, and fold it over. Repeat 4 times (each side), then cover again.

Step 4: Pre-Shape and Rest

Gently turn the dough out onto a floured surface. Use a bench scraper to gently shape it into a round or oval. Let it rest uncovered for 20–30 minutes.

Step 5: Final Shape

Do a gentle final shaping — pulling the dough taut by tucking the edges underneath — and place it seam-side up in a floured proofing basket or bowl lined with a towel.

Step 6: Final Proof

Cover and let rise for 1–2 hours at room temp or overnight in the fridge for 8–12 hours (for more flavor and easier scoring).

Step 7: Preheat Oven

Place a Dutch oven or baking stone inside the oven and preheat to 475°F (245°C) for at least 30–45 minutes.

Step 8: Bake

Carefully turn the dough onto parchment paper (seam side down), score the top with a razor or sharp knife, and place it into the hot Dutch oven. Cover and bake for 20 minutes, then uncover and bake for another 20–30 minutes or until deep golden brown.

Step 9: Cool

Let the bread cool completely on a wire rack before slicing — at least 1 hour. This helps the crumb set and keeps the crust crisp.

📝 Notes

• Hydration Matters: This recipe is ~75% hydration. If you’re new to sourdough, reducing water slightly (to 350g) may make handling easier.

• Don’t Skip the Preheat: A ripping-hot oven is crucial for oven spring and crust development.

• No Dutch Oven? Use a baking stone and place a tray of water in the oven to create steam.

• Flavor Tips: Overnight cold proofing enhances sourness and texture.

• Starter Check: Make sure your sourdough starter is active — it should pass the “float test” (a spoonful in water floats).

❓ FAQs

Can I make this without a sourdough starter?

No, this recipe relies on wild yeast from the starter. For quicker bread, try a yeast-based artisan loaf instead.

Why is it called “Unloaf”?

Because it’s not baked in a loaf pan! It’s a free-form, naturally shaped sourdough.

Can I bake it directly on a baking sheet?

Yes, but the crust and rise will be better with a Dutch oven or baking stone due to steam retention.

How do I store Unloaf Sourdough?

Wrap it in a clean towel or store in a paper bag at room temperature for up to 3 days. Freeze for long-term storage.

Why is my crust too hard or chewy?

Overbaking or lack of steam in the oven can lead to a tough crust. Try adding steam or reducing bake time slightly.
