1 Kg Sourdough Bread Recipe: Crusty Bite, Tangy Crumb in One Rise

This 1 kg sourdough bread recipe delivers the perfect balance of a crusty exterior and open, airy crumb—all with just one rise. The secret lies in precise fermentation control, where time and temperature work together to develop that signature tang and texture. I’ve refined this method over years of baking, ensuring even home bakers can achieve bakery-quality results without the guesswork.

What sets this recipe apart is the single bulk fermentation (8-12 hours at room temperature) followed by a short cold proof (2-4 hours in the fridge). This approach builds flavor while maintaining structure, eliminating the need for multiple rises or complicated schedules. The dough is forgiving yet responsive—ideal for both beginners and experienced bakers.

By the time it emerges from the oven, you’ll have a golden, crackling crust with a crisp shatter and an interior so open it practically melts in your mouth. The tangy crumb comes from proper fermentation, not additives, making this bread as nutritious as it is delicious. Every slice reveals that perfect balance of chew and airiness.

Perfect for sandwiches, toast, or serving with soups, this loaf keeps well for days. The recipe includes starter maintenance tips if you’re new to sourdough, so you can bake with confidence. Let’s get started on your first perfect loaf.

Ingredients for 1 kg sourdough bread

Nine essential ingredients transform your kitchen into a bakery—crusty, tangy perfection awaits.

The sourdough starter is your flavor foundation—look for a bubbly, domed starter that doubles in 4-6 hours. King Arthur flour delivers consistent results, but any high-gluten bread flour works. Whole wheat adds subtle depth without overpowering. For butter, Land O’Lakes or Plugrá work best when cold—take it straight from the fridge. The sugar isn’t just for sweetness; it helps create that signature crust. Diamond Crystal salt is less dense than table salt, so measure carefully. Water temperature matters: too hot kills yeast, too cold slows fermentation. Lukewarm (around 80°F) is ideal—think bathwater, not boiling.

No sourdough starter? Instant yeast (¼ tsp) + 1 tbsp sugar can substitute in a pinch, but the flavor won’t be authentic. Short on whole wheat? Extra ½ cup all-purpose flour maintains structure. Butter too soft? Chill it for 20 minutes before adding. For scoring, a lame or sharp razor creates those perfect gas vents—no fancy tools needed. The cornmeal isn’t just for dusting; it adds a subtle sweetness to the crust. If your kitchen’s too warm, place the dough in the fridge for 1-2 hours to slow fermentation. The ice water at the end? That’s your secret weapon for a crisp crust—don’t skip it.

Freshly baked sourdough keeps for 3-4 days at room temperature, wrapped in a clean kitchen towel. For longer storage, freeze slices wrapped in parchment—3-6 months in a sealed bag. The crust stays crisp for days if you avoid plastic wrap (it traps moisture). To revive stale bread, wrap in foil and warm in a 350°F oven for 5-10 minutes. Pro tip: Save scraps for sourdough croutons or bread pudding—waste not, want not. The starter? Feed it daily with equal parts flour and water to keep it active for your next bake.

Step-by-step instructions for perfect 1 kg sourdough bread

This method delivers a golden crust and airy crumb with just one rise—no overnight waits or complicated folds.

In a large mixing bowl, combine the 5 cups all-purpose flour and 0.5 cup whole wheat flour. Create a well in the center and add the 0.25 cup active sourdough starter, 1.5 cups lukewarm water, 1.5 tsp Diamond Crystal kosher salt, and 0.5 tsp granulated sugar. The dough will be shaggy at first—that’s normal.

Using a wooden spoon or dough whisk, stir until just combined, then let the dough rest for 5 minutes. This initial hydration allows the flour to absorb water evenly. After resting, wet your hands and begin stretching and folding the dough from the center outward, rotating the bowl 90 degrees after each fold. Repeat this process 4 times, resting 30 seconds between each fold. You’re developing gluten now—the more you work it, the better the crumb structure will be.

After the final fold, the dough should be smooth and slightly tacky but not sticky. If it sticks to your hands, sprinkle a little more flour, but don’t overdo it—too much flour weakens gluten development. Cover the bowl with a damp towel and let it rest at room temperature for 30 minutes. This short rest relaxes the gluten before shaping.

After the rest, turn the dough onto a lightly floured surface. Gently pat it into a 12-inch square about ½-inch thick. This is where the butter comes in—cut the 0.25 cup cold unsalted butter into 8 equal pieces and place them evenly spaced across the dough surface. Fold the dough over the butter, sealing the edges tightly to encase the butter completely. This creates those beautiful laminations that give sourdough its signature texture.

Roll the dough into a 16-inch log, sealing the seam tightly. Fold the log in half like a letter, then fold it in half again to form a compact rectangle. This final shaping tightens the structure and prepares the dough for the final proof. Dust a clean kitchen towel with 0.25 cup cornmeal and place the shaped dough seam-side down on the towel. Cover loosely with another towel and let it rest for 15 minutes at room temperature.

This short rest allows the dough to relax slightly before the final proof. The cornmeal prevents sticking and adds a subtle flavor to the crust. The dough should feel slightly springy when pressed gently—this is your signal that it’s ready for the next step.

After the 15-minute rest, gently unwrap the dough and place it on a lightly floured surface. Shape it into a round boule by pulling the edges toward the center and tucking them under. The dough should be smooth and taut, with no loose edges. Place the boule seam-side up on a parchment-lined baking sheet, cover it with a damp towel, and let it proof at room temperature for 1 to 1.5 hours.

You’ll know it’s ready when the dough has risen by about 50% and springs back slowly when poked gently with a fingertip. The surface should look slightly domed and feel firm to the touch. If the dough rises too quickly, place it in the refrigerator for 15 minutes to slow the fermentation and develop more flavor.

While the dough proofs, preheat your oven to 450°F with a Dutch oven inside (if using one) or a baking stone on the middle rack. The oven should be fully preheated before baking—this ensures a rapid rise and crispy crust. Once the dough is fully proofed, use a sharp razor or lame to score the top in a crosshatch pattern, about ¼-inch deep. This controlled cut directs the oven spring and creates that iconic sourdough crust.

Carefully transfer the scored boule to the preheated oven. If using a Dutch oven, place the lid on immediately to trap steam and create that steamy environment essential for a crispy crust. Bake for 20 minutes with the lid on, then remove the lid and bake for an additional 20 to 25 minutes until the crust is deep golden brown and sounds hollow when tapped on the bottom.

The internal temperature should reach 205°F at the center. If the top browns too quickly, tent the bread loosely with foil to prevent over-browning. The bread is done when the crust is crisp, the internal temperature is correct, and the bread pulls away slightly from the sides of the pan.

Remove the bread from the oven and transfer it to a wire rack to cool completely. Resist the temptation to slice it immediately—the crust will firm up as it cools, and the crumb will set properly. Once fully cooled, slice with a serrated knife for clean cuts and serve warm for the best texture and flavor.

Flavor customization for this recipe

Tangy vs. Mild

Adjust fermentation time to control tanginess—longer fermentation equals more sour flavor. For a mild loaf, proof the dough for 6-8 hours at room temperature before baking. To intensify tang, extend fermentation to 10-12 hours or add 1 extra tablespoon of starter for a bolder flavor. I find 8 hours strikes the perfect balance for everyday eating. 💛

Sweet Additions

Swap the 0.5 tsp sugar for 1 tbsp honey or 1 tbsp maple syrup to enhance sweetness in the crust. For a caramelized finish, brush the baked loaf with 1 tbsp melted butter mixed with 1 tsp brown sugar while still warm. This creates a beautiful amber crust with subtle sweet notes—perfect for breakfast toast.

Herb Infusions

Add 1 tbsp finely chopped rosemary or thyme directly to the dough during mixing for an aromatic twist. For a Mediterranean flair, sprinkle 1 tsp dried oregano and ½ tsp red pepper flakes into the flour before combining. Fresh herbs like dill or basil work beautifully but should be added after the final proof for maximum fragrance.

Seed and Nut Boosts

Mix ¼ cup toasted sesame seeds or sunflower seeds into the dough for texture and nutrition. For extra crunch, press ¼ cup chopped walnuts or almonds onto the surface before baking. I love a pumpkin seed and honey combo—sprinkle 2 tbsp seeds mixed with 1 tsp honey on top after scoring for a gourmet touch.

Whole Grain Variations

Replace ½ cup all-purpose flour with ½ cup rye flour for a denser, heartier loaf. For a nutty depth, use ½ cup spelt flour instead of whole wheat. These substitutions add complexity but may require 10-15 extra minutes of kneading to develop gluten properly. The rye version pairs perfectly with sharp cheeses like aged Gouda.

Spiced and Smoky

Add ½ tsp cinnamon and ¼ tsp nutmeg for a subtle spiced flavor, ideal for breakfast loaves. For a smoky twist, mix ½ tsp smoked paprika into the dough or brush the baked loaf with 1 tbsp liquid smoke (use sparingly!). This works surprisingly well with garlic butter for sandwiches. 🔥
