Side Dishes
This artisan sourdough bread recipe using King Arthur flour delivers bakery-quality results with minimal effort—no-knead, Dutch oven crust, and a foil-sealed center that stays tender for days. The secret lies in the flour’s high protein content, which creates that signature open crumb and crispy exterior while maintaining a soft interior.
I’ve perfected this method after years of testing, ensuring even beginners achieve a loaf with a crackly crust and airy, chewy crumb.
The process begins with a pre-fermented starter (or use a store-bought one for convenience), followed by a simple dough that ferments overnight. King Arthur’s flour works magic here—its blend of proteins and enzymes develops gluten gradually, resulting in a loaf with both structure and tenderness.
The Dutch oven traps steam, creating that iconic oven-spring and thick, golden crust, while the foil-sealed bottom keeps the crumb soft.
By the time you pull it from the oven, you’ll have a loaf with a shatteringly crisp crust, an open crumb structure, and a flavor that’s tangy yet balanced—no sourness, just pure artisan bread character. The best part?
This method requires no special equipment beyond a Dutch oven (or a heavy pot with a lid) and a little patience. Even if your first loaf isn’t perfect, the troubleshooting tips ensure you’ll nail it the next time.
Perfect for feeding a crowd, gifting, or simply enjoying with butter and jam, this recipe transforms a simple flour blend into something extraordinary. Let’s get started on your first loaf—your kitchen will smell like a Parisian boulangerie in no time.

King Arthur Bread Flour is non-negotiable here—its 28% protein content delivers that signature open crumb and crispy crust. Grab the 5-pound bag from King Arthur's website or your local baking supply store; it's worth every penny for this recipe. The starter? Store-bought is fine (check the expiration date—it should be bubbly and active), but if you're ambitious, cultivate your own using this flour. For the Dutch oven, Lodge makes the gold standard—if you don't own one, borrow or rent; the steam it traps is what creates that bakery-quality crust. Pro tip: Season your Dutch oven before using by baking it empty at 350°F for an hour with a little oil—it'll last you decades.
No King Arthur flour? White Lily or Caputo Tipo 00 are solid backups—just know the crumb might be slightly denser. Using a store-bought starter? Make sure it's 100% hydration (equal parts flour and water) and at its peak activity (small bubbles throughout, not just on top). For the autolyse stage, unbleached all-purpose flour works, but the protein structure won't be as strong. Short on cornmeal? Semolina or rice flour are great substitutes—they just add a slightly different texture to the crust. The olive oil can be swapped for vegetable or canola oil, but olive adds a subtle richness that pairs perfectly with the sourdough's tang. And if you're feeling fancy, infuse the oil with a few sprigs of rosemary before using for a fragrant twist.
This dough is a marathon, not a sprint—plan for 18-24 hours from start to finish. The starter should be fully fermented (doubled in size with bubbles) before mixing, and the dough needs at least 12 hours of bulk fermentation at room temperature. For shaping, ice water is your secret weapon—it cools the dough instantly, making it easier to handle. Store your reserved flour in an airtight container with a silica gel packet to keep it fresh for months. The baked loaf? Cool completely on a wire rack (never cut warm)—it'll stay fresh for 5-7 days at room temperature, wrapped in a clean kitchen towel. For longer storage, freeze slices between parchment paper; they'll reheat beautifully in a toaster or oven.

Step-by-step instructions for artisan sourdough bread recipe King Arthur
Here's how to create that perfect no-knead loaf with a crackly crust and tender crumb.
Mix the Autolyse for Optimal Gluten Development
In a large mixing bowl, combine the 4 cups King Arthur Bread Flour and the 2.25 cups Warm Water (between 95-100°F) until just combined. You'll notice the dough will look shaggy and sticky at this stage—that's completely normal. This initial mix, called an autolyse, allows the gluten to begin developing while we let the dough rest.
Cover the bowl with a damp kitchen towel and let the dough rest for 30-45 minutes. During this time, the dough will become smoother and more cohesive as the gluten strands relax and strengthen. This step is crucial for creating that open, airy crumb structure we're after with King Arthur's high-protein flour.
Incorporate Starter and Salt for Fermentation
After the autolyse, add the 0.5 cup Active Sourdough Starter and the 1.5 tsp Sea Salt to the dough. Using a dough scraper or your hands, gently fold these ingredients into the dough until fully incorporated. You should see the dough become slightly firmer and more elastic as the salt begins to strengthen the gluten structure.
Now comes the bulk fermentation. Cover the bowl again and let the dough ferment at room temperature for 4-6 hours, until it has nearly doubled in size and looks puffy with bubbles throughout. I like to do this on the countertop near the oven where it's warm but not hot—around 75-78°F. The dough should pass the "poke test": when you gently press your finger into the dough, it should spring back slowly rather than immediately.
Prepare the Dutch Oven for Baking
While the dough ferments, preheat your oven to 450°F. Place the 1 whole Dutch Oven (with lid) inside the oven to preheat as well. This ensures your baking vessel reaches the same temperature as the oven, which is crucial for that perfect crust development. While it's heating, lightly grease the Dutch oven with 1 tbsp Olive Oil, then dust the bottom generously with 0.25 cup Cornmeal. This creates a non-stick surface and adds to that beautiful crust texture.
Once the dough has fermented sufficiently, turn it out onto a lightly floured surface. Gently shape it into a round boule by pulling the edges toward the center and tucking them under. The dough will be quite sticky, so don't be afraid to use the 0.5 cup King Arthur Bread Flour reserved for shaping. This final shaping helps create that tight, even structure we want in our loaf.
Create the Steam Bath for Crust Development
Carefully transfer the shaped dough to the prepared Dutch oven. The dough should fit snugly inside—if it's too large, gently press down on the top to create a more compact shape. Place the lid on the Dutch oven and bake for 20 minutes at 450°F. This initial baking period creates steam inside the Dutch oven, which is essential for developing that beautiful oven spring and crispy crust.
After 20 minutes, remove the lid and switch to 425°F. Bake for another 20-25 minutes until the bread reaches an internal temperature of 205-210°F and develops a deep golden brown color. You'll know it's done when you tap the bottom of the loaf and it sounds hollow. The crust should be crackly and crisp, while the interior should be soft and airy.
Cool and Enjoy Your Artisan Creation
Remove the bread from the Dutch oven and transfer it to a wire rack. Here's the crucial part: let it cool completely for at least 1 hour before slicing. I know it's tempting to cut into that warm, fragrant loaf immediately, but the bread continues to set as it cools, and slicing too soon can make it gummy and disappointing.
Once fully cooled, slice into thick pieces to reveal that beautiful open crumb structure. The exterior should have a crisp, crackly crust with a slightly charred appearance in spots, while the interior should be soft, chewy, and filled with those characteristic sourdough holes. The flavor should be tangy from the starter, with a subtle saltiness that enhances every bite. Serve warm with butter or olive oil for the ultimate experience.
Pro Tips For Making Artisan Sourdough Bread Recipe King Arthur
- Test Starter Temperature: King Arthur Bread Flour loves warmth—your starter too. Feed it when it’s between 75-78°F (24-26°C) to guarantee peak activity. Cold starter? Pop it in a warm spot (like your oven with the light on) for 20 minutes before mixing. I learned this the hard way when my dough took three times longer to rise because I ignored the thermometer.
- Weigh Your Flour: Skip the scooping—King Arthur Bread Flour packs differently, and volume measurements lie. Use a scale for the all-purpose flour too (even if the recipe says "cup"). A 10-gram difference in a 500g batch changes the dough’s structure. Yes, it’s one extra step, but your crust will thank you.
- Autolyse First: Mix the bread flour and warm water alone for 30-60 minutes before adding starter or salt. This hydrates the flour fully, making the final knead (or stretch-and-folds) way easier. I was skeptical until I tried it—now I never skip it.
- Steam the Oven: No Dutch oven? No problem—but don’t skip the steam. Toss a metal bowl of boiling water on the oven floor for the first 15 minutes of bake. The King Arthur Bread Flour’s high protein needs that extra push for a crisp crust. (Pro move: Add ice cubes to the water for longer-lasting steam.)

Frequently asked questions
Can I use a store-bought sourdough starter instead of making my own?
King Arthur's high-protein flour works beautifully with store-bought starters. Just ensure it's active (bubbly and doubled in size) and at its peak fermentation (usually within 3-5 days of purchase). For best results, feed it 1:1:1 (flour:water:starter) 4-6 hours before using in your dough. The starter's acidity will develop more fully during the long bulk fermentation, giving you that perfect tangy flavor without needing a long-term culture.
Why does my dough look too sticky after mixing?
King Arthur Bread Flour's high protein content (28%) creates a more elastic gluten network, but the dough will naturally feel very wet during autolyse. This is normal! The hydration level (about 70%) is intentionally high for that open crumb structure. If it's unbearably sticky, use your reserved flour sparingly during shaping—just enough to prevent sticking, not to dry it out. Wet hands work better than dry flour for handling. The dough will firm up during bulk fermentation as gluten develops.
How do I know when the dough is fully fermented?
Look for three key signs: the dough should nearly double in size, have visible bubbles throughout (not just on top), and pass the "poke test." Gently press your finger into the dough—it should spring back slowly (like Jell-O) rather than immediately (like a firm ball). With King Arthur flour, the dough may feel slightly dense but should still show significant volume increase. Temperature matters too: aim for 75-78°F for optimal fermentation speed. If your kitchen is cooler, extend fermentation by 1-2 hours.
Can I bake this without a Dutch oven?
Yes, but you'll sacrifice some of that signature crust development. Use a heavy pot with a tight-fitting lid instead, and place it on the bottom rack of your oven. For extra steam, add a tray of boiling water to the oven. Shape your loaf on parchment paper for easier transfer. The crumb will still be excellent, but the crust may be less crispy. Pro tip: Score deeper than usual to encourage oven spring. The King Arthur flour's protein will still give you that open crumb even without the Dutch oven's steam bath.
Why did my loaf come out dense instead of airy?
Dense bread usually stems from underproofing or overhandling the dough. With King Arthur flour, the gluten develops quickly—don't exceed the 6-hour bulk fermentation window. Also check your starter: if it's sluggish, it won't provide enough lift. Another common mistake is shaping too aggressively, which can deflate the dough. For your next attempt, try cold fermentation (refrigerate dough overnight) which gives more control over proofing. And remember: the dough should feel relaxed and slightly jiggly before baking, not firm and resistant.
