King Arthur White Bread Recipe: Artisan-Style Loaf With Tangy Sourdough Depth

Baking King Arthur white bread with tangy sourdough depth transforms your kitchen into a professional bakery. This recipe leverages King Arthur flour’s high protein content to create a loaf with a crisp crust and airy interior, all while incorporating a subtle sourdough tang that elevates everyday sandwiches.

The process is methodical but rewarding, with precise timing and temperature control ensuring consistent results every time.

What sets this recipe apart is the balance between simplicity and technique—no fancy equipment required, just a standard kitchen scale and mixing bowl. The dough develops naturally through bulk fermentation, allowing gluten to strengthen for that signature artisan texture.

Proofing and shaping are critical steps where attention to detail ensures an even rise and professional-looking loaf.

By the final bake, you’ll achieve a golden-brown crust with a hollow sound when tapped—a hallmark of perfectly baked bread. The interior remains tender yet sturdy, ideal for slicing thick sandwiches or serving warm with butter. This recipe delivers restaurant-quality results at home, proving that great bread doesn’t require shortcuts.

Whether you’re a beginner or an experienced baker, this method builds confidence with clear instructions and troubleshooting tips. The tangy sourdough depth adds complexity without overpowering the classic white bread flavor, making it versatile for any meal. Let’s get started on crafting your perfect loaf.

Ingredients for king arthur white bread

Four cups of King Arthur flour and a touch of sourdough starter create an artisan loaf with restaurant-quality depth.

The King Arthur Bread Flour is non-negotiable here—its high protein content (12.7%) ensures proper gluten development for that signature artisan texture. Purchase directly from King Arthur Flour’s website for guaranteed freshness, or verify the protein percentage on your grocery store bag. Diamond Crystal kosher salt is preferred over table salt due to its fine grain and lower sodium content, which allows for more precise flavor control. For the sourdough starter, maintain a 100% hydration ratio (equal parts flour and water) and feed it daily with King Arthur Bread Flour for consistency. The active dry yeast should be no older than four months; check the expiration date on the package.

No sourdough starter? Substitute with 0.5 cup plain yogurt for mild tang, though results will lack depth. Running low on whole milk? Evaporated milk or heavy cream works in a pinch, but the fat content will slightly alter the dough’s texture. The butter must be cold and cubed—microwave it for 20 seconds if needed to soften slightly for easier incorporation. For the sugar, honey or maple syrup can replace granulated at a 1:1 ratio, though it may slightly alter fermentation timing. Always use room-temperature ingredients to ensure even hydration and proper yeast activation.

Store unused King Arthur flour in an airtight container at room temperature for up to 12 months, though it’s best used within 6 months for optimal freshness. The sourdough starter can be refrigerated for up to 2 weeks or frozen for 6 months—simply revive by feeding with flour and water before use. Proofed dough remains viable in the fridge for up to 24 hours, though it’s best baked immediately for peak texture. The finished loaf stays fresh for 3-4 days at room temperature, wrapped in a clean kitchen towel to prevent drying. For longer storage, slice and freeze portions for 3 months—reheat in a toaster or oven for best results.

Step-by-step instructions for artisan white bread with sourdough depth

This method delivers a crisp crust, open crumb, and subtle tang from the sourdough starter.

In a medium bowl, combine the 0.5 cup sourdough starter, 1.5 cups water, and 1 tbsp granulated sugar. Let this mixture sit at room temperature for 1-2 hours until it becomes bubbly and nearly doubles in volume. This activation ensures your starter is vigorous and contributes proper fermentation.

In a separate large bowl, whisk together the 4 cups king arthur bread flour and 1.5 tsp diamond crystal kosher salt. Create a well in the center and add the activated sourdough mixture, 1 cup whole milk, 1 whole large eggs, and 0.5 cup unsalted butter (cubed). Using a wooden spoon or dough whisk, gradually incorporate the dry ingredients into the wet until a shaggy dough forms.

Turn the dough onto a lightly floured surface and knead for 8-10 minutes by hand, or use a stand mixer with a dough hook attachment on medium speed for 5-6 minutes. The dough should become smooth, elastic, and slightly tacky but not sticky. If it sticks to your hands or the surface, add 1 tablespoon of water at a time until it reaches the proper consistency.

Here’s the thing—you’re aiming for a dough that springs back slowly when poked. This indicates proper gluten development, which is essential for that open crumb structure we’re after. Wrap the dough tightly in plastic wrap and let it rest at room temperature for 1 hour. This initial rest allows the gluten to relax, making shaping easier later.

After the rest, punch down the dough gently to release any air bubbles. Divide it into 4 equal portions (each roughly 8 ounces) and shape each into a round ball. Place them seam-side up in a lightly greased bowl, cover with a damp towel, and let them proof at room temperature for 1-2 hours or until they’ve risen by about 50%. The dough should feel light and springy when pressed gently.

While the dough proofs, prepare your baking environment. Preheat your oven to 375°F and place a Dutch oven with a lid in the oven to heat as well. The residual heat from the Dutch oven will create that perfect steam environment for a crisp crust. When the dough has risen sufficiently, transfer it to a floured surface and shape each piece into an oval loaf.

Carefully transfer each shaped loaf to the hot Dutch oven, spacing them about 1 inch apart. Cover the Dutch oven with the lid and bake for 25 minutes. This initial covered bake steams the bread, creating that signature open crumb structure. After 25 minutes, remove the lid and continue baking for another 10-15 minutes until the bread is golden brown and sounds hollow when tapped on the bottom.

Real talk: Your oven might run hot, so start checking at the 20-minute mark. The bread is done when it reaches an internal temperature of 190-200°F. If the tops brown too quickly, tent them loosely with aluminum foil to prevent over-browning while the centers finish baking. Remove the bread from the Dutch oven and let it cool on a wire rack for at least 1 hour before slicing.

Make-ahead tips for this dish

Dough Prep Ahead

Mix your dough up to 24 hours ahead and refrigerate it in an airtight container. The cold slows fermentation, giving you more control over the final rise. When ready to bake, let the dough sit at room temperature for 1-2 hours until it’s slightly puffy and springs back when poked.

This method works especially well if you’re baking in the morning—just pull it out overnight and let it come to temperature while you preheat the oven. 💡

Proofing Flexibility

Proof your shaped loaves in the fridge overnight for a slower, more controlled rise. Transfer the dough to the fridge after the initial bulk fermentation and let it proof for 8-12 hours. This cold proofing enhances flavor development and makes shaping easier.

When baking, add 10-15 minutes to your bake time since the dough will be colder. The result? A more complex flavor profile with a slightly denser crumb—perfect for sandwiches. ❄️

Freezer-Friendly Loaves

Shape your loaves, proof them until just under 50% risen, then freeze them on a floured baking sheet for 1 hour to firm up. Transfer to a sealed freezer bag for up to 3 months.

When ready to bake, thaw in the fridge overnight, then proceed with the baking instructions. The freeze-thaw process actually improves the bread’s texture, making it even more tender. Just add 5-10 minutes to your bake time. ⏰

Batch Baking Strategy

Double the recipe and bake two loaves at once in your Dutch oven. Use a 9×5-inch pullman pan for the second loaf to maximize oven space. This is a game-changer for meal prep—you’ll have fresh bread ready for 4-5 days.

Store the second loaf wrapped in a clean kitchen towel at room temperature, and slice it as needed. The key is to bake them simultaneously for even heat distribution. 🌾

Reviving Stale Bread

If your bread starts to dry out, revive it by wrapping a slice in a damp paper towel and microwaving it for 10-15 seconds. For larger portions, place the entire loaf in a sealed plastic bag with ½ cup water and microwave on high for 20 seconds**.
