1 Kg Sourdough Bread Recipe: Hands-Off Crusty Loaf With Tangy Depth

A 1 kg sourdough bread recipe delivers restaurant-quality crust and open crumb with minimal daily effort—no kneading, no fuss, just hands-off fermentation and a perfect bake. The tangy depth comes from a well-fed starter and precise hydration, while the structure relies on time and patience rather than brute force.

This method transforms simple flour and water into a loaf with a crisp, caramelized crust and an airy interior that holds up to days of storage.

The secret lies in the autolyse and bulk fermentation, which develop gluten gradually without overworking the dough. You’ll mix just 500g flour, 300g water, 10g salt, and 200g active starter, then let the dough rest for hours while the flour hydrates and gluten forms naturally.

This approach eliminates guesswork—no overproofing, no dense crumb—just reliable results every time.

By the final proof, your dough will be jiggly and domed, ready for shaping into a boule or batard. A sharp razor scores the surface just before baking, creating those signature ear-like openings while trapping steam for maximum oven spring.

The high-heat bake with steam produces that iconic crusty exterior and open crumb, while the slow cool prevents gummy texture.

This recipe scales perfectly for home bakers—no special equipment beyond a Dutch oven or baking stone. The hands-off method means you can prep dough in the morning and bake in the evening, with minimal active time.

Whether you’re feeding a family or perfecting your technique, this foolproof 1 kg sourdough delivers professional results without the complexity.

Ingredients for 1 kg sourdough bread

Simple flour, active starter, and precise hydration create this restaurant-quality sourdough with minimal effort.

The bread flour is non-negotiable—its high protein content (12-14%) develops the gluten structure essential for that open crumb. King Arthur or Caputo are trusted brands for consistent results. Your sourdough starter should be at peak activity (50-75% hydration), with visible bubbles and a tangy aroma. If it’s sluggish, feed it 1:1:1 (flour:water:starter) by weight 6-12 hours before using. The filtered water must be room temperature—cold water shocks the starter, while warm water overproofs the dough. For the salt, Diamond Crystal dissolves more cleanly than table salt, preventing flavor imbalances. Buy flour in 5 lb bags to maintain freshness and avoid oxidation from repackaging.

No bread flour? All-purpose flour plus 1 tbsp vital wheat gluten per cup works in a pinch, though texture will be slightly less open. Your starter weak? Add 1 tsp sugar or honey to the feed to boost activity. Short on time? Use a pre-fermented starter from a trusted source (like Breads Bakery) to skip the 5-7 day starter-building process. The olive oil isn’t for flavor—it coats your hands and dough, preventing sticking during shaping. For the gluten addition, Bob’s Red Mill instant vital wheat gluten is the most reliable brand. If you’re gluten-sensitive, omit it entirely—the dough will still rise, just with a slightly less chewy crumb.

Store unused flour in an airtight container in a cool, dark pantry for up to 3 months. Your active starter should be refrigerated between feeds, with a weekly 1:1:1 feed to maintain strength. The dough can be prepped 24 hours ahead—cover tightly and refrigerate until ready to shape. Once baked, cool the loaf on a wire rack for at least 2 hours to prevent gummy texture. Wrap in a clean kitchen towel and store at room temperature for 3-5 days, or freeze sliced bread for 3 months in a sealed bag. The crust hardens as it cools, so slice just before serving for maximum freshness.

Step-by-step instructions for artisan sourdough bread

Here’s the precise method for developing flavor and structure in your 1 kg loaf.

In a large mixing bowl, combine the 4.41 cups unbleached bread flour and 1.6 cups filtered water at room temperature. Use your hands or a dough whisk to break up any dry patches until just combined—this initial hydration phase is called autolyse. The dough will look shaggy and wet at first.

Cover the bowl loosely with plastic wrap and let rest for 30 minutes. During this time, the flour begins absorbing water and developing gluten strands. You’ll notice the dough gradually transform from a rough mass into a smoother, more cohesive texture. This step ensures better gluten formation later, leading to a lighter crumb and improved oven spring.

After the autolyse, add the 14.1 oz active sourdough starter and 0.35 oz kosher salt to the dough. Using a dough scraper, gently fold these ingredients into the center of the dough, then perform a series of stretch-and-folds. For each fold, wet your hands slightly, grab one side of the dough, stretch it upward, and fold it over itself. Rotate the bowl and repeat this process 4-5 times.

Next, sprinkle the 0.7 oz instant vital wheat gluten evenly over the dough surface. This optional ingredient enhances chewiness and structure. Cover the bowl again and let rest for 30 minutes. The gluten will begin developing more visibly during this time, creating a slightly tacky but elastic dough. If the dough feels too sticky, you can add up to 1 tablespoon of the reserved flour from your mixing bowl.

After the 30-minute rest, perform another set of stretch-and-folds, this time rotating the bowl 90 degrees between each fold for even gluten development. Let the dough rest another 30 minutes, then repeat the stretch-and-folds once more. This three-stage bulk fermentation process typically takes 2-3 hours total, depending on your kitchen temperature.

During bulk fermentation, the dough should roughly double in size and develop visible bubbles along the surface. The ideal temperature for this stage is 75-78°F—if your kitchen is cooler, extend the fermentation time. You’ll know the dough is ready when it passes the “poke test”: gently press your finger into the dough. If it springs back slowly (not immediately) and leaves a slight indentation, it’s ready for shaping.

Turn the dough onto a lightly floured surface and gently shape it into a round boule. To do this, use your fingertips to create surface tension by pulling the dough toward you in a circular motion. As you work, rotate the dough clockwise to maintain even tension. The goal is to create a tight, smooth surface with no weak spots.

Place the shaped dough seam-side up in a lightly oiled proofing basket or bowl. Cover and refrigerate for 12-16 hours (overnight). This cold proof slows fermentation, allowing flavors to develop more deeply. In the morning, remove the dough from the fridge and let it come to room temperature for 1-2 hours before baking. The dough should have noticeably risen and developed a slightly domed shape with visible bubbles.

Preheat your oven to 450°F with a Dutch oven inside for 45 minutes. While the oven heats, transfer the dough to a piece of parchment paper. Using a razor blade or sharp lame, score the dough with a ½-inch deep diagonal cut on the top. This prevents the dough from bursting open during baking and creates an attractive opening.

Carefully transfer the scored dough (with parchment) into the hot Dutch oven. Bake covered for 20 minutes, then remove the lid and bake uncovered for an additional 20-25 minutes until the crust reaches a deep golden brown color. The internal temperature should reach 205-210°F when measured at the center. The bread will have a hollow sound when tapped on the bottom.

Remove the bread from the Dutch oven and transfer it to a wire rack. Let it cool completely for at least 2 hours before slicing. This resting period allows the crumb to set properly and prevents a gummy texture. The bread should have a crisp crust with an open, airy crumb structure and a tangy, complex flavor from the well-developed sourdough starter.

Slice the bread with a serrated knife and serve with your favorite toppings. The first few slices should be reserved for immediate consumption—the fresh, warm bread has the best texture and most intense flavor. Store any leftovers wrapped in a bread bag at room temperature for up to 3 days or freeze for longer storage.

Autolyse Mastery

This 30-minute rest before mixing is where gluten development begins. I’ve found that skipping it leads to dense crumb and poor oven spring—don’t rush! The dough should look shaggy at first but gradually become smoother as gluten strands form.
