King Arthur Artisan Sourdough Bread Recipe: Hands-Off Rise to Crusty, Open-Crumbed Loaves

This artisan sourdough bread recipe using King Arthur flour delivers restaurant-quality loaves with crispy crusts and open, airy crumb—no baking experience required. The secret lies in a hands-off rise that lets the dough develop naturally, creating that signature tang and texture without constant monitoring.

I've perfected this method after years of testing, ensuring even beginners achieve professional results with minimal effort.

The process begins with a simple starter (or you can use store-bought for convenience), then moves to mixing, bulk fermentation, shaping, and proofing—each step designed to maximize flavor and texture. Using a Dutch oven creates that iconic oven spring and crackly crust, while precise scoring ensures an even rise.

The recipe includes troubleshooting tips for common issues like dense crumb or pale crust, so you'll know exactly how to adjust.

What you'll end up with is a loaf that smells like a Parisian bakery, with a golden, shatteringly crisp crust and an interior filled with those coveted open crumbs.

The flavor develops over time, becoming more complex with each day, making it perfect for sandwiches, toast, or simply enjoying fresh from the oven. This is the kind of bread that transforms everyday meals into something special.

Whether you're a first-time baker or a seasoned pro, this method delivers consistent, foolproof results. The dough is forgiving, the rise is hands-off, and the final product is worth every minute of wait time. Let's get started on your first loaf—your kitchen will never smell the same again.

Ingredients for artisan sourdough bread recipe king arthur

King Arthur flour and a lively starter are your foundation for restaurant-quality sourdough at home.

King Arthur Bread Flour is the secret weapon here—its high protein content gives you that perfect open crumb and crispy crust. Buy it in bulk from King Arthur's website or your local baking supply store for the freshest results. The starter needs to be active and bubbly (like a jiggly, foamy pancake batter)—if yours is sluggish, feed it with equal parts flour and water 2-3 times before using. For butter, Plugrá or Land O'Lakes unsalted work beautifully, but any good-quality European-style butter will do. The honey should be raw and liquid—Manuka or clover both work well, but avoid processed honey if possible. Cornmeal? Bob's Red Mill or any fine-ground variety will give you that perfect golden crust when used in the Dutch oven.

No active starter? Store-bought sourdough bouillon or a 1:1:1 mix of flour, water, and white vinegar can kickstart one in 5-7 days. Short on butter? Coconut oil or extra-virgin olive oil adds richness, though it won't replicate butter's flavor exactly. The honey can be swapped for maple syrup or agave, but honey's subtle floral notes are ideal. If your flour is old (over 3 months), toast it lightly in a dry pan for 5 minutes to revive its structure. For the Dutch oven prep, cornmeal works best—semolina gives a prettier crust but is harder to find. And if you're in a pinch, a heavy oven-safe pot with a lid works too, though the crust won't be quite as crisp.

Store your starter in an airtight jar at room temperature, feeding it daily with equal parts flour and water. It'll keep indefinitely if maintained properly. The mixed dough can be refrigerated for up to 24 hours before shaping—just let it sit at room temp for 1 hour before final proof. For the shaped loaf, cover with a damp towel and proof at room temp for 1-2 hours or in the fridge overnight for deeper flavor. Baked loaves keep well wrapped at room temp for 3 days or frozen for up to 3 months. Toast slices directly from frozen for fresh-baked flavor anytime.

Step-by-step instructions for King Arthur artisan sourdough bread

Here's how to transform simple ingredients into a crusty, open-crumbed loaf with minimal effort.

In a large mixing bowl, combine the 5 cups King Arthur Bread Flour, 1 cup Active Sourdough Starter, 3.5 cups Warm Water (measured at 105°F), 1 tbsp Honey, and 2 tsp Diamond Crystal Kosher Salt. Use a wooden spoon or dough whisk to mix until no dry flour remains—about 2 minutes. The dough should be shaggy but cohesive.

Next, add the 0.25 cup Unsalted Butter, cut into small cubes, and mix until fully incorporated. The butter should melt slightly but not completely. Cover the bowl with a damp kitchen towel and let the dough rest at room temperature for 30 minutes. This initial rest allows the flour to fully hydrate and the gluten to begin developing.

After the 30-minute rest, perform a series of stretch-and-folds every 30 minutes for 2 hours. To do this, wet your hands to prevent sticking, grab one side of the dough, stretch it upward, and fold it over itself. Rotate the bowl and repeat this process all around the dough. You'll notice the dough becomes smoother and more elastic with each fold.

This step is critical for building gluten strength, which gives the bread its signature open crumb and chewy texture. After the final stretch-and-fold, let the dough rest uncovered at room temperature for 30 minutes again. This final rest ensures the gluten relaxes, making shaping easier.

Lightly dust a clean surface with 0.5 cup All-Purpose Flour. Transfer the dough to the floured surface and gently shape it into a loose round, using your hands to create surface tension. Place the dough seam-side up in a lightly greased bowl, cover it with the damp towel, and let it proof at room temperature for 1-2 hours, or until it has nearly doubled in size. You'll know it's ready when the dough springs back slowly when poked with a finger.

If your kitchen is warm, the dough may proof faster. If it's cool, it may take longer. The goal is to achieve a dough that's puffy but still slightly underproofed—this ensures an open crumb during baking.

Preheat your oven to 450°F. Place a Dutch oven (or a heavy oven-safe pot with a lid) in the oven while it preheats. While the oven heats, sprinkle 0.5 cup Cornmeal evenly into the Dutch oven. This creates a crispy, golden crust on the bottom of the loaf.

Once the oven reaches temperature, carefully remove the Dutch oven and transfer the shaped dough to the cornmeal-lined bottom. The dough should be taut and slightly domed. Cover the Dutch oven with the lid and bake for 30 minutes. This initial bake steams the bread, creating that iconic open crumb.

After 30 minutes, remove the lid and bake for an additional 15-20 minutes, or until the bread is deep golden brown and the internal temperature reaches 205-210°F. The bread is done when it sounds hollow when tapped on the bottom.

Let the bread cool in the Dutch oven for 10 minutes, then transfer it to a wire rack to cool completely. This cooling period allows the steam inside the loaf to escape, preventing a gummy texture. Once fully cooled, slice and enjoy the crispy crust and airy interior that make artisan sourdough so special.

Storing and reheating this recipe

Room-Temp Storage

Freshly baked sourdough keeps best at room temperature for 3 days when stored in a paper bag or canvas bread box. The paper bag mimics a bakery environment by trapping moisture while allowing air circulation.

I place my loaf in a King Arthur linen bread bag—it’s breathable and keeps the crust crisp longer than plastic. Avoid refrigerating unless you plan to slice it, as cold temperatures dry out the crumb faster. 🌾

Refrigerator Preservation

If you must refrigerate, wrap the entire loaf tightly in plastic wrap or beeswax wrap, then place it in a ziplock bag to prevent drying. It’ll stay fresh for 5-7 days, but the texture will become slightly denser.

For sandwiches, slice and freeze portions on a tray before bagging—they’ll toast up like fresh-baked. I use King Arthur’s reusable silicone bags for easy reheating.

Freezer for Long-Term

For maximum freshness, freeze the loaf unwrapped on a tray for 2 hours to harden, then transfer to a freezer bag with parchment paper between slices. This prevents freezer burn and keeps it crispy for 3 months.

Thaw at room temperature for 4 hours or reheat 20 minutes at 300°F wrapped in foil. My go-to method? Toast slices directly from frozen—they crisp up beautifully with a sprinkle of cornmeal for extra crunch. ❄️

Reheating Like a Pro

For that just-baked flavor, reheat slices in a skillet over medium heat for 1-2 minutes per side until golden. A toaster oven at 350°F works too—just 5 minutes for even warmth.

Avoid microwaves unless you’re desperate: they turn sourdough gummy. Pro tip: Brush slices with melted butter before toasting for a restaurant-worthy finish. 🔥

Reviving Day-Old Bread

Dry slices? No problem. Sprinkle with water, cover, and steam in the microwave for 20 seconds. For a crispy crust, toast in a cast-iron pan with a pat of butter.

My favorite hack? Tear old bread into croûtons or breadcrumbs—they’re perfect for soups, meatballs, or as a crunchy topping for salads. Waste not, want not! 💫
