Ingredients for australian sourdough bread
Four key ingredients transform flour into that signature Australian sourdough crunch.
| Ingredient | Amount | Notes |
|---|---|---|
| Unbleached Bread Flour 🌾 | 5 cups | High-protein for structure and chew |
| Active Sourdough Starter 🍞 | 1 ½ cups | 100% hydration, bubbly and active |
| Filtered Water 💧 | 3 ¼ cups | Room temperature, 75-80°F |
| Kosher Salt 🧂 | 1 ½ tsp | Diamond Crystal preferred |
| Honey 🍯 | 1 tbsp | For starter feeding (optional) |
| Whole Wheat Flour 🌾 | ½ cup | For added texture (optional) |
| Olive Oil 🫒 | 1 tbsp | For bowl and dough |
| Cornmeal 🌽 | ¼ cup | For Dutch oven dusting |
| Ice Water ❄️ | ½ cup | For shaping and tension |
The bread flour is non-negotiable here—its high protein content (12-14%) gives that signature open crumb and chewy texture. King Arthur or Caputo are my go-tos, but any unbleached bread flour with 12%+ protein works. For the sourdough starter, it needs to be active (bubbly when dropped in water) and ideally maintained at 75-80°F for consistency. If your starter's sluggish, feed it with equal parts flour and water 2-3 times before baking. The filtered water matters too—chlorine or heavy metals can inhibit fermentation, so avoid tap water if your municipal supply is treated aggressively.
No active starter? Wild fermentation with flour and water takes 5-7 days, but for this recipe, you'll need to source one from a trusted baker or online supplier. Short on time? Commercial starter like Biga or San Francisco sourdough works in a pinch, though the flavor won't be as authentic. The honey addition is optional but helps prime your starter if it's been neglected—just mix it into the feeding water. For the whole wheat flour, if you're adding it, toast it lightly first to deepen its flavor and prevent over-fermentation. And that olive oil? Use a fruity, extra-virgin variety—it adds subtle richness that carries through to the final loaf.
Store your sourdough starter in the fridge between uses—it'll last 2-3 weeks if fed weekly. The bread flour keeps indefinitely in a cool, dark pantry, but once mixed, your dough should bake within 24 hours for optimal flavor development. If you're prepping ahead, shape the dough and refrigerate it overnight—this actually improves flavor through cold fermentation. The cornmeal is your secret weapon for that crispy bottom crust; don't skip the dusting step. And that ice water? It's not just for shaping—it creates surface tension that helps the gluten structure hold during the long bake.

Step-by-step instructions for Australian sourdough bread
Master the art of Australian-style sourdough with this foolproof method for a crispy crust and open crumb.
Mix the Dough with Precision
In a large mixing bowl, combine the 5 cups unbleached bread flour, 0.5 cup whole wheat flour, and 1.5 tsp kosher salt. Create a well in the center and add the 1.5 cups active sourdough starter and 3.25 cups filtered water at room temperature. Stir with a wooden spoon until just combined—you'll see wet spots remain.
Add the 1 tbsp honey and 1 tbsp olive oil, then mix again until fully incorporated. The dough should be shaggy but hold together when pressed. Avoid overmixing at this stage—this ensures proper gluten development later. Cover the bowl with a damp kitchen towel and let rest for 30 minutes at room temperature. This initial rest allows the flour to hydrate fully and the gluten to begin relaxing.
Develop the Dough Through Bulk Fermentation
After the initial rest, wet your hands and perform a series of stretch-and-folds every 30 minutes for 2 hours. To do this, dip your fingers in water, grab one side of the dough, stretch it upward, and fold it over itself. Rotate the bowl and repeat this motion all around the dough. This technique builds strength and elasticity while distributing the yeast and starter evenly.
During this bulk fermentation, the dough should roughly double in size. You'll notice bubbles forming on the surface and a slight jiggle when the bowl is moved. The ideal temperature for this stage is 75-78°F—if your kitchen is cooler, extend the fermentation time by 30-60 minutes. The dough is ready when it passes the "poke test": gently press your finger into the dough and watch for a slow, graceful spring back rather than an immediate rebound.
Shape and Pre-Ferment the Dough
Lightly flour a clean work surface and turn out the dough. Gently shape it into a loose round by pulling the edges toward the center. Place the dough seam-side up in a lightly oiled bowl, cover with the damp towel, and refrigerate for 12-16 hours. This cold proof creates tension in the gluten structure, which is crucial for that signature Australian open crumb and crispy crust.
During this time, the dough will develop flavor and rise slightly. The cold fermentation also allows the gluten to relax, making it easier to handle during final shaping. I like to set a timer for the overnight rest—this ensures consistency even if you're not monitoring it constantly.
Final Shape and Bake in the Dutch Oven
Preheat your oven to 475°F with a Dutch oven inside for 45 minutes. Remove the Dutch oven and dust the bottom generously with 0.25 cup cornmeal. Turn the cold dough onto the floured surface and shape it into a tight boule by pulling the edges toward the center and sealing the seam. Use your hands to create surface tension—this helps maintain the round shape during baking.
Carefully transfer the shaped dough to the hot Dutch oven, seam-side up. Immediately pour 0.5 cup ice water into the bottom of the Dutch oven—this creates steam, which is essential for developing that crispy crust and open crumb. Bake covered for 20 minutes, then remove the lid and bake uncovered for an additional 20-25 minutes until the crust is deep golden brown and sounds hollow when tapped on the bottom.
Cool and Enjoy
Remove the bread from the Dutch oven and transfer it to a wire rack. Let it cool completely—this can take 2-3 hours. The internal temperature should drop below 130°F before slicing. This cooling period allows the gluten to fully relax and the crumb to set properly, preventing a gummy texture.
Slice the bread and serve warm for the best experience. The crust should be crisp with a satisfying crunch, while the interior should have an open, airy crumb with visible holes. Store any leftovers wrapped in a clean kitchen towel to maintain freshness for up to 3 days at room temperature.
Pro Tips For Making Australian Sourdough Bread
- STRETCH AND FOLD: I learned this the hard way—after mixing your starter, flour, and honey, resist the urge to knead like dough for pizza. Instead, do 3-4 sets of stretch-and-folds (every 30 minutes) during bulk fermentation. This develops gluten without overworking it, and your loaf will hold its shape better in the oven. (Yes, even if you're impatient like me.)
- WEIGH YOUR WATER: Filtered water is non-negotiable for this recipe, but measuring by weight—not volume—is the thing that matters most. A 500g flour batch needs ~350g water (adjust if your starter is wetter). Eyeballing leads to gummy dough or dry crumb. I skip this when I'm lazy, but the difference in texture is noticeable.
- SALT THE DOUGH: Add all your kosher salt during the final mix, not sprinkled on top later. It dissolves better and distributes evenly, which prevents weak spots in the crumb. I was skeptical until I tried it—now I can taste the difference in crust flavor and oven spring.
- HONEY HYDRATION MATTERS: Use room-temperature honey—cold thickens it, throwing off your hydration. Warm it gently (20 seconds in a bowl of hot water) until it flows like thin syrup. This ensures even distribution in the dough, not sticky pockets that burn in the oven. (Your future self will thank you.)
Troubleshooting your australian sourdough bread
Dough Too Sticky?
If your dough feels impossible to handle during shaping, you likely need more flour—but don’t overdo it. I recommend using King Arthur or Caputo bread flour (they absorb moisture better than all-purpose).
Wet your work surface with ice water (about ¼ cup) and dust lightly with flour only where needed. The goal is to create surface tension, not a floury mess.
If the dough still sticks, try shaping it into a boule while it’s still in the bowl—just tip it onto parchment paper and gently roll it onto the counter. 💫
Fermentation Issues
If your dough isn’t rising enough, check your starter first—it should float in water like a cork. If it’s sluggish, feed it 1:1:1 (flour:water:honey) and wait 4-6 hours for activity.
For bulk fermentation, aim for 75-78°F—use a proofing box or place your dough near a warm oven if your kitchen is cold. Overproofing? Look for a dough that springs back slowly when poked (not immediately). If it’s already collapsed, bake it anyway—the flavor will still be great! ⏰
Flat or Dense Crumb
A dense loaf usually means underproofed dough or insufficient gluten development. Make sure you’re doing stretch-and-folds every 30 minutes for 2 hours during bulk fermentation. For shaping, create tight surface tension by pulling edges toward the center and sealing the seam.
If your oven runs hot, reduce temp to 450°F and add 5-10 minutes to baking time. A thermometer is your best friend here—aim for 475°F accurately. 🌡️
Pale or Soft Crust
For that signature crispy crust, steam is key. Pour ½ cup ice water into your Dutch oven before baking—this creates the necessary humidity. If your crust is still pale, try baking 5 minutes longer uncovered at the end.
Preheating the Dutch oven for 45 minutes ensures even heat distribution. For extra crunch, sprinkle coarse sea salt on the dough before the final bake. 🔥
Uneven Rise
Uneven rise often happens when dough isn’t shaped properly or the oven isn’t hot enough. Before baking, ensure your dough is a tight boule with no weak spots. Use a digital thermometer to confirm your oven hits 475°F.
If your kitchen is drafty, place a baking stone on the lower rack for 30 minutes before baking. For extra insurance, bake the dough on a parchment-lined tray inside the Dutch oven. 💡

Frequently asked questions about Australian sourdough bread
What makes Australian sourdough different from other sourdough?
The key differences lie in the long fermentation times (12-16 hours cold proof) and the use of high hydration dough (75-80% hydration). Australian sourdough also emphasizes a crispy, crackly crust achieved through Dutch oven baking with steam, while the interior develops that signature open, airy crumb. The flavor is more tangy and complex due to the extended fermentation process.
Can I make this recipe without a Dutch oven?
Yes, but you'll need to create steam another way. Place a baking tray on the oven rack below your loaf and pour ½ cup boiling water into it when you put the bread in the oven. For best results, bake on a perforated baking sheet lined with parchment paper. The crust won't be as crispy, but you'll still get good flavor and structure.
How do I know when my sourdough starter is ready?
Your starter is ready when it's bubbly, doubles in size within 4-6 hours after feeding, and floats in water like a cork. For this recipe, it should be at its peak activity—right after a feeding when it's most vigorous. If it's sluggish, feed it with equal parts flour and water (plus a little honey) and wait until it shows these signs before using.
Can I add seeds or nuts to this recipe?
Add ¼ cup seeds (sesame, sunflower, or pumpkin) or ½ cup chopped nuts (walnuts or almonds) during the final mix. For best results, toast the seeds/nuts first and incorporate them gently during the last stretch-and-fold. Just be aware they'll make the dough slightly denser. Store-bought mixes work too—just reduce the bread flour by the same amount.
Why does my bread taste bland?
Bland flavor usually means insufficient fermentation. Ensure your starter is active and your bulk fermentation lasts at least 4-6 hours at 75-78°F. For extra depth, try adding 1 tsp malt powder or ½ tsp instant yeast to the dough. Also, make sure you're using filtered water—chlorine or heavy metals can inhibit flavor development. Let the bread cool completely before slicing too—warm bread can taste underdeveloped.
