Master this 4-loaf sourdough bread recipe and watch your kitchen become an artisan bakery—all in one day, effortlessly. The secret lies in a foolproof schedule—maintaining an active starter, precise fermentation times, and oven spring that rivals professional bakeries.
I’ve perfected this method after years of trial and error, ensuring every loaf develops that signature open crumb and crispy crust without requiring overnight vigilance.
This recipe balances tradition with modern efficiency: stretch-and-folds build gluten for structure, while cold proofing allows flexibility in your timeline. The dough comes together in under 30 minutes, then ferments while you handle other tasks—no all-night wait required.
With a 900°F steam bath in your oven, you’ll achieve that coveted oven spring that makes sourdough irresistible.
By the final loaf, you’ll have golden, crackling crusts and an airy interior that crumbles like cloud. The beauty of this method is its adaptability: bake all four loaves at once for a weekend feast, or space them out for daily fresh bread.
Each loaf tastes like it came from a Parisian boulangerie, but with techniques any home baker can master.
Whether you’re feeding a crowd or stocking your freezer, this system delivers restaurant-quality sourdough without the guesswork. The key is patience—letting time work in your favor for flavor development. Let’s get started on your first perfect batch.
Ingredients for 4 loaf sourdough bread
Four loaves of restaurant-quality sourdough start with these precise ingredients—each playing its part in structure and flavor.
| Ingredient | Amount | Notes |
|---|---|---|
| Active Sourdough Starter 🍞 | ½ cup | 100% hydration, bubbly and active |
| All-Purpose Flour 🌾 | 10 cups | Bread flour preferred for structure |
| King Arthur Bread Flour 🌾 | 2 cups | For enhanced gluten development |
| Granulated Sugar 🍚 | ½ cup | White or raw cane preferred |
| Unsalted Butter 🧈 | ½ cup | Cold, cubed for stretch-and-folds |
| Instant Yeast 🍞 | ¼ tsp | Optional for extra rise |
| Diamond Crystal Kosher Salt 🧂 | 1 ½ tsp | Fine grain preferred |
| Water 💧 | 3 ½ cups | Room temperature, filtered |
| Rice Flour 🌾 | ¼ cup | For dusting bannetons |
| Cornmeal 🌽 | ½ cup | For parchment lining |
| Ice Cubes ❄️ | ¼ cup | For cold proofing |
The King Arthur Bread Flour and all-purpose flour blend is non-negotiable for that signature open crumb. King Arthur has the perfect protein content for sourdough, while the all-purpose adds flexibility. For the starter, it must be 100% hydration—anything less risks a dense loaf. I always grab my flour from Whole Foods or King Arthur’s website for consistency. The unsalted butter needs to be cold when you handle it during stretch-and-folds—take it out of the fridge right before you start. For salt, Diamond Crystal dissolves better than table salt, so you won’t get that bitter aftertaste. If you’re in a pinch, use table salt but reduce to 1 tsp—it’s more concentrated.
No King Arthur flour? Bread flour from Bob’s Red Mill works almost as well, but you might need an extra 0.25 cup for structure. Short on butter? Coconut oil melts during mixing, but it won’t give the same flavor. The instant yeast is optional—your starter should do all the work, but if you’re baking in cooler climates, it helps kickstart fermentation. For the water, tap water with chlorine works fine, but if yours tastes metallic, use filtered. The rice flour is key for dusting bannetons—it prevents sticking without adding flavor. No rice flour? Semolina is your next best bet, but it’s heavier. The cornmeal on parchment isn’t just for looks—it creates a crispy barrier between the dough and paper.
Store your flour in an airtight container in a cool, dark place—it keeps for 6-12 months. The sourdough starter lives in the fridge between bakes, fed weekly with equal parts flour and water. For the butter, keep it sealed in the fridge until you’re ready to use it. Once you’ve shaped your loaves, they’ll keep covered at room temperature for 2-3 hours before baking. Baked loaves? Cool completely on a wire rack, then wrap in parchment paper for up to 3 days. Freeze slices for 6 months**—toast straight from frozen for freshness every morning.
Why You’ll Love This Recipe

Step-by-step instructions for 4-Loaf sourdough bread
Here’s how to transform your starter into four perfect loaves with minimal hands-on time.
Mix the Dough Using the Stretch-and-Fold Method
In a large mixing bowl, combine the 0.5 cup active sourdough starter, 10 cups all-purpose flour, 2 cups King Arthur bread flour, 0.5 cup granulated sugar, 0.5 cup unsalted butter (cold, cubed), 0.25 tsp instant yeast, and 1.5 tsp Diamond Crystal kosher salt. Add 3.5 cups room-temperature water and mix until just combined—you should have a shaggy, sticky dough.
Cover the bowl with a damp kitchen towel and let it rest for 30 minutes. This initial rest allows the gluten to begin developing. Then perform the stretch-and-fold technique: wet your hands, grab one side of the dough, stretch it upward, and fold it over itself. Rotate the bowl and repeat this process four times, spaced 30 minutes apart. After the final fold, let the dough rest for 2 hours at room temperature until it doubles in size and becomes bubbly. The dough should pull back slowly when you poke it with a wet finger—this indicates proper fermentation.
Divide, Shape, and Cold Proof the Dough
Once the dough has risen, turn it out onto a lightly floured surface and divide it into four equal portions (about 2 pounds each). Shape each portion into a boule by rounding it into a ball, then sealing the seams by tucking the edges under. Place the shaped loaves on a parchment-lined baking sheet, cover them loosely with plastic wrap, and refrigerate for 12 hours. Cold proofing slows fermentation, allowing for better flavor development and easier handling later.
Here’s the thing—this step is where the magic happens. The cold slows down yeast activity just enough to create a more complex flavor profile. When you remove the loaves from the fridge, they should have risen slightly but still feel firm to the touch. If they’ve expanded too much, return them to the fridge for another 2-3 hours to firm up before baking.
Preheat and Prepare for Baking
Preheat your oven to 450°F with a Dutch oven inside for 45 minutes. While the oven heats, dust four bannetons (or small bowls) with 0.25 cup rice flour and line the bottoms with parchment paper. Sprinkle 0.5 cup cornmeal onto a separate baking sheet—this will help prevent sticking when you transfer the loaves.
Once the Dutch oven is hot, carefully remove it from the oven and place it on a heatproof surface. Transfer each cold-proofed loaf to its prepared banneton, seam-side up. Cover the bannetons with damp kitchen towels and let the loaves rise at room temperature for 1-2 hours until they’ve expanded to about 75% of their final size. The dough should feel springy when pressed gently—this indicates it’s ready for the oven.
Score, Bake, and Develop Crust
Using a razor blade or sharp knife, score each loaf diagonally about ½ inch deep—this helps control expansion and creates a beautiful crust. Carefully transfer the bannetons with the loaves into the preheated Dutch oven. Place the Dutch oven back into the oven and bake for 20 minutes at 450°F. After 20 minutes, remove the lid and bake for another 20-25 minutes until the loaves are deep golden brown and sound hollow when tapped on the bottom.
Here’s where attention to detail pays off: the steam from the Dutch oven creates that iconic sourdough crust, while the final uncovered bake develops color and crunch. If the tops brown too quickly, tent loosely with foil. The internal temperature should reach 205-210°F when measured with an instant-read thermometer. Let the loaves cool on a wire rack for at least 1 hour before slicing—they’ll continue to set and develop flavor as they cool.
Rest and Enjoy Your Artisan Bakes
Once cooled, remove the loaves from the bannetons and let them rest on a wire rack for 2-3 hours to ensure the crumb fully develops. The bread should have a crisp crust with an open, airy crumb inside. Each loaf should yield about 16-18 slices, perfect for sandwiches or toast. Store any leftovers wrapped in a bread bag at room temperature for up to 3 days, or freeze for up to 3 months for freshness.
This method delivers professional-quality sourdough with minimal effort. The key is patience—letting the dough work its magic through cold proofing and proper fermentation. Trust the process, and you’ll end up with loaves that rival your favorite artisanal bakery.
Pro Tips For Making 4 Loaf Sourdough Bread
- Scale with Confidence: Weigh your flours in grams—not cups—when making four loaves. The recipe’s blend of all-purpose and King Arthur bread flour relies on precise ratios, and volume measurements can throw off hydration. I learned this the hard way when my third loaf turned out gummy because I eyeballed the flour.
- Feed Starter First: Refresh your sourdough starter 12–18 hours before mixing the dough. A hungry starter (with 1:1:1 flour-to-water-to-starter ratio) ferments faster and gives you more control over bulk fermentation timing. Skipping this step means fighting sluggish rise later—trust me, your dough will thank you.
- Shape Tightly, Cover Loosely: Wrap shaped loaves in plastic wrap first, then place in proofing baskets. The plastic keeps surfaces smooth while allowing the dough to expand freely—no sticking, no tears. I used to skip this and ended up with lopsided loaves that looked like they’d been through a fight.
- Steam the Dutch Oven: Preheat your Dutch ovens with a metal tray of boiling water on the bottom rack before baking. The residual steam locks in that crisp crust for the first 15 minutes—critical for four loaves in one oven. I tried spraying water mid-bake once, and it just made the kitchen steamy and the crust uneven.
Essential equipment for this recipe
Dutch Oven Essentials
The Dutch oven is your secret weapon for achieving that iconic sourdough crust and oven spring. I swear by the Le Creuset 5.5-quart—it retains heat beautifully and creates the perfect steam environment.
If you’re on a budget, the Lodge 5.5-quart is a fantastic alternative with excellent heat distribution. Both are oven-safe up to 500°F, which is crucial for that initial steam bath. 🔥
For best results, preheat your Dutch oven inside the oven for 45 minutes before baking. This ensures even heat distribution and maximum steam generation.
If you don’t have a Dutch oven, you can use a cast-iron skillet or even a heavy metal bowl lined with parchment paper, but results won’t be as consistent.
The lid should fit snugly to trap steam—if it doesn’t, use a separate oven-safe bowl with a lid to create a similar effect.
Bannetons and Shaping Tools
Bannetons (proofing baskets) give your loaves their signature shape and texture. I recommend KitchenAid 9-inch bannetons—they’re durable and easy to clean. If you’re just starting out, plastic bannetons work fine, but linen-lined ones (like Utopia Kitchen) create a better texture.
For shaping, a dough scraper and bench brush are indispensable. The scraper helps divide and shape the dough cleanly, while the bench brush keeps your work surface dusted with flour. 🌾
No bannetons? No problem. Use small bowls lined with parchment paper or even greased ramekins—just be prepared for slightly less defined shapes. The key is to create a tight, rounded boule with smooth seams.
If your dough sticks, dust generously with rice flour or semolina—it prevents sticking better than all-purpose flour. For scoring, a razor blade or sharp serrated knife works best, but a pizza wheel in a pinch will do the job.
Precision Thermometers
A thermometer is non-negotiable for perfect sourdough. I use an instant-read thermometer (like Thermoworks ThermoPop) to check both dough temperature and internal loaf temp. Your dough should be between 75-78°F before shaping, and your loaves should reach 205-210°F internally for optimal texture.
An oven thermometer (like Taylor Precision) ensures your oven is actually at 450°F—many home ovens run hot or cold, and this small investment saves you from under- or over-baked loaves. 🌡️
For cold proofing, a digital thermometer helps monitor fridge temps—your fridge should stay at 38-40°F for consistent results. If your dough isn’t rising properly, it might be too warm.
Pro tip: Place your dough in a cooler with ice packs if your fridge runs hot, or use a proofing box (like Breville Smart Oven) for precise temperature control. These tools might seem like extras, but they’re game-changers for consistency.
Flour and Storage Containers
Flour quality makes all the difference in sourdough. Store your King Arthur Bread Flour and all-purpose flour in airtight containers (like OXO Good Grips) to keep them fresh. I keep mine in the freezer for long-term storage—this preserves flavor and prevents rancidity.
For daily use, a cool, dark pantry works fine. The rice flour and cornmeal should also be stored in airtight containers, but they’re less sensitive to light and moisture. 🌾
A scale (like Escali Primo) is worth the investment—measuring flour by weight ensures accuracy, especially when dividing your dough into four equal portions. If you’re using volume measurements, spoon flour into the cup and level it off with a knife for consistency.
For butter, a microplane or box grater** gives you uniform cubes, which melt beautifully during stretch-and-folds. Don’t skip the cold butter—it adds structure and flavor to your dough.

Frequently asked questions
Why does this recipe use both bread flour and all-purpose flour?
The King Arthur bread flour provides the high protein content needed for that signature open crumb and chewy texture, while the all-purpose flour adds flexibility and prevents a dense loaf. This blend creates the perfect balance of structure and tenderness in each of your four loaves. Think of it as the architectural support and softness working together!
Can I make these loaves without a Dutch oven?
Yes, but your crust won’t be as crispy or develop the same oven spring. Use a cast-iron skillet or heavy metal bowl lined with parchment paper instead. Place it on the oven rack and pour 1 cup hot water in a tray below to create steam. The results won’t be identical, but you’ll still get great flavor development. For best results, try to find a Dutch oven secondhand—they’re worth the investment!
What if my dough doesn’t rise properly during cold proofing?
Check your fridge temperature—it should be 38-40°F. If it’s warmer, your dough will ferment too quickly. Try placing the dough in a cooler with ice packs or use a proofing box for precise temperature control. Also verify your starter is active (it should float in water). If all checks out, extend cold proofing by another 2-3 hours—patience is key with sourdough!
How do I know when the loaves are fully baked?
Your loaves are done when they’re deep golden brown and sound hollow when tapped on the bottom. The internal temperature should reach 205-210°F on an instant-read thermometer. If the tops brown too quickly, tent loosely with foil. The crust should be crispy while the crumb remains soft and airy—this is the hallmark of perfect sourdough!
Can I freeze the dough before baking?
Shape your loaves as directed, then wrap them tightly in plastic wrap and place in the freezer. When ready to bake, thaw in the fridge overnight, then proceed with the final proof and baking steps. This is a great way to prep ahead for busy weekends. Just remember to let them thaw completely before baking—never bake frozen dough!
