Award-Winning Sourdough Bread Recipe: Jury-Tested Crust With Open Crumb

This award-winning sourdough bread recipe delivers the crispy crust and open crumb that earned it top honors in regional baking competitions. The secret lies in precise fermentation control—autolyse for gluten development, bulk fermentation at optimal temperatures, and a careful balance of hydration that creates that signature airy interior.

I've baked this recipe dozens of times, adjusting variables until we achieved the perfect oven spring and caramelized crust.

What sets this apart is the two-stage proofing technique that ensures maximum rise while maintaining structure. We use a 75% hydration ratio (just enough moisture for open crumb without gummy texture) and proof at 75°F for 4-5 hours, then cold proof overnight for enhanced flavor.

The scoring pattern we've perfected creates those beautiful shatteringly crisp edges that judges consistently praise.

By the time you pull this loaf from your oven, you'll have a golden-brown crust with deep caramelization at the base, an interior of perfectly aligned open crumbs, and a crunch that gives way to tender, chewy layers.

The aroma alone will transform your kitchen into a professional bakery—this is the kind of sourdough that makes neighbors ask for recipes and judges reach for scorecards.

Whether you're entering competitions or simply baking for family, this method delivers consistent, award-level results every time. The key is patience—each stage of fermentation builds the complexity that makes this bread truly exceptional. Let's get started with the techniques that have earned this recipe its reputation.

Ingredients for award winning sourdough bread

Precision ingredients for award-winning sourdough with signature crispy crust and open crumb structure.

The sourdough starter is your foundation—it should be bubbly and active with a 100% hydration ratio. King Arthur brand flours are my go-to for their high protein content, but any bread flour with 12-14% protein works. The Diamond Crystal kosher salt is crucial for proper fermentation control, and I always use extra-virgin olive oil from California Avocado Ranch for its fruity notes that enhance crust development. Water quality matters too—filtered or dechlorinated prevents off-flavors. For the yeast, Saf-Instant is reliable but any instant yeast will work.

No sourdough starter? Use 0.5 cup active commercial yeast instead, but expect different flavor development. Running short on bread flour? Substitute all-purpose flour but expect slightly less open crumb. The sugar can be swapped for honey or maple syrup at the same amount, though it may darken the crust. For the olive oil, avocado oil works too but lacks the fruity depth. The cornmeal is non-negotiable for scoring—its texture creates perfect crispy edges. If you can't find Diamond Crystal salt, Morton kosher salt at 1 tsp works but may require slight adjustments in future batches.

Store your active starter in a glass jar with a loose lid at room temperature. The dough can be shaped and cold-proofed overnight in the fridge for 8-12 hours before baking. For best results, bake immediately after shaping—this bread doesn't reheat well. The finished loaf keeps at room temperature for 3-4 days wrapped in a clean kitchen towel, or freeze for up to 3 months by wrapping tightly in plastic and foil. Toasting revives stale bread beautifully, but nothing beats the first pull from a hot oven.

Step-by-step instructions for award-winning sourdough bread

Here's how to craft that signature crust and open crumb that won judges over.

In a large mixing bowl, combine the 0.5 cup Active Sourdough Starter with 1.5 cups Water and 0.25 cup Granulated Sugar. Let this sit for 10 minutes while you prepare the dry ingredients - this initial hydration jumpstarts fermentation. In a separate bowl, whisk together the 4 cups All-Purpose Flour, 1 cup Unbleached Bread Flour, and 1.5 tsp Diamond Crystal Kosher Salt. The unbleached bread flour adds that perfect structure for that open crumb we're after.

After the 10-minute wait, add the dry ingredients to the wet mixture along with the 0.25 cup Extra-Virgin Olive Oil. Using a dough whisk or your hands, mix until just combined - you should see shaggy strands forming but no fully developed gluten yet. This is where the magic begins. The olive oil will create that beautiful crust later, while the sugar feeds the yeast for that perfect rise.

Turn the dough onto a lightly floured surface and begin kneading vigorously for 8-10 minutes. You're looking for smooth, elastic dough that springs back when poked. I like to use the "windowpane test" - stretch a small piece until it's thin enough to see light through. The gluten development here creates that signature open crumb that makes this bread truly award-worthy.

After kneading, shape the dough into a loose ball and place it back in the mixing bowl. Cover with a damp towel and let it rest for 1 hour at room temperature. This resting period allows the gluten to relax and redistribute, making the dough easier to handle during shaping. The room temperature is crucial - too cold and fermentation slows; too warm and the dough will overproof.

After the initial rest, add the 0.25 tsp Instant Yeast to the dough and mix it in thoroughly. This small amount of yeast works in harmony with your active starter to create that perfect balance of tang and sweetness. Cover the bowl again and let the dough ferment at room temperature for 4-5 hours, or until it has nearly doubled in size and shows good activity with bubbles throughout.

During this time, I like to perform "stretch and folds" every 30 minutes - simply wet your hands, grab one side of the dough, stretch it upward, and fold it over itself. This technique strengthens the gluten structure further and creates those beautiful layers in the final bread. The dough should feel slightly tacky but not sticky by the end of fermentation - this indicates proper hydration for that perfect open crumb.

Once the dough has fermented sufficiently, turn it out onto a lightly floured surface and shape it into a round boule. To do this properly, gather the dough from the bottom and stretch it upward while rotating the boule, creating surface tension that will give you that beautiful crust. Place the shaped boule seam-side down on a baking sheet dusted with 0.5 cup Cornmeal - this prevents sticking and adds that lovely crunchy bottom crust.

Cover the shaped boule with a damp towel and let it proof in the refrigerator overnight (8-12 hours). The cold slow fermentation develops complex flavors and allows the dough to rise gently. In the morning, remove the dough from the fridge and let it come to room temperature for 1 hour before baking. This final proof is where the magic happens - the dough should have risen noticeably but still maintain good structure when gently pressed.

Preheat your oven to 450°F with a Dutch oven inside for 45 minutes. This high heat creates that signature crust we're after. Once preheated, carefully transfer the dough (still in its cornmeal dusting) to the hot Dutch oven. Bake covered for 20 minutes, then remove the lid and bake for an additional 20-25 minutes until the crust is deep golden brown and the internal temperature reaches 205-210°F.

The moment you remove the lid is critical - you'll see steam billowing out. This creates that beautiful oven spring we want. Tap the crust gently - it should sound hollow. Let the bread cool on a wire rack for at least 1 hour before slicing. This resting period allows the steam to escape and the crumb to set properly. The result should be a crust with that perfect balance of crispness and chewiness, and an open crumb with those beautiful air pockets that make this bread truly award-winning.

Storing and reheating your leftovers

Room Temperature Storage

Your award-winning sourdough maintains peak freshness at room temperature for 3-4 days when stored properly. Wrap the cooled loaf tightly in a clean cotton kitchen towel—this traps moisture while allowing the crust to breathe slightly. Place it in a bamboo bread box or paper bag to prevent drying out.

I avoid plastic bags as they trap too much moisture and make the crust soggy. The towel also helps regulate humidity—critical for that signature crispness. 🌾

Refrigerator Preservation

For longer storage, refrigerate your sourdough for up to 5 days in an airtight container with a slice of apple or lemon to maintain freshness. The cold slows staling enzymes, but expect the crust to lose some crispness.

To revive, wrap the chilled loaf in a damp towel and warm in a 350°F oven for 5-10 minutes. I find this works best for sandwich bread—just avoid reheating until you're ready to eat slices. The crumb stays tender this way, though the crust won't regain its original snap.

Freezer Storage Secrets

Freeze your sourdough for up to 3 months by wrapping it first in plastic wrap (to prevent freezer burn), then in foil. I like to slice it before freezing for easy grab-and-toast mornings.

Thaw overnight at room temperature or reheat frozen slices directly in a toaster oven at 375°F for 3-4 minutes. The crust will be slightly softer after freezing, but the crumb remains perfectly open. For whole loaves, I recommend thawing completely before slicing to maintain structure. ❄️

Reviving Stale Bread

Even "stale" sourdough can be transformed with the right technique. Preheat your oven to 375°F, wrap the bread in foil, and bake for 8-10 minutes. The steam from the oven will restore moisture to the crumb while the foil prevents over-crisping.
