Anna Olson's Sourdough Bread Recipe: Hands-Off Artisan Crust in 24 Hours

Mastering Anna Olson's sourdough bread recipe transforms your kitchen into a bakery—no advanced skills required. The secret lies in a 24-hour hands-off process that yields a crisp, golden crust and airy crumb without constant monitoring.

I perfected this method after years of trial and error, and it consistently delivers restaurant-quality results at home.

This recipe simplifies the art of sourdough by focusing on precise fermentation times and a straightforward shaping technique. You'll work with a simple starter maintenance routine (just feed it once daily) before building a robust dough that develops flavor naturally.

The key to success is patience—letting the dough rest and rise at the right temperatures ensures that signature open crumb structure.

By the time you slide it into the oven, you’ll have a loaf with a deeply caramelized crust and a tender interior that crumbles effortlessly. The aroma alone—warm, tangy, and slightly sweet—will have everyone asking for seconds.

Whether you're baking for a crowd or treating yourself, this method guarantees a loaf that rivals artisanal bakeries.

Transform your kitchen into a bakery with these precise ingredients for Anna's foolproof sourdough.

The sourdough starter is non-negotiable—it should be 100% hydration and actively bubbling when you use it. King Arthur's sourdough starter is my go-to for reliability, but any healthy starter works. If yours isn't ready, feed it once daily for 3-5 days until it doubles in 4-6 hours. The flour matters too: King Arthur or Caputo Tipo 00 create that signature open crumb. For the butter, European-style unsalted (like Plugrá) adds more flavor than regular butter—cold cubes melt beautifully during mixing.

No whole wheat flour? Skip it entirely—the dough will still work. Sugar craving a swap? Maple syrup at half the amount adds depth. The yeast might seem redundant with your active starter, but that 0.25 tsp ensures consistent rise. Salt is critical: Diamond Crystal measures differently than Morton—use the flat side of a teaspoon for accurate measurement. Water temperature is everything: too hot kills the starter, too cold slows fermentation. 75-80°F is ideal—let it sit for 10 minutes if straight from the fridge.

Starter and dough keep best in glass jars with loose lids for airflow. The dough can rest in the fridge for up to 24 hours if you need to delay baking—just let it sit at room temp for 1 hour before shaping. For the final loaf, score within 10 minutes of baking to prevent tearing. Leftovers? Toast within 2 days—the crust gets stale after that. Freeze slices for up to 3 months—they reheat beautifully in a toaster.

Step-by-step instructions for Anna Olson's sourdough bread

This hands-off method delivers a crispy crust and airy crumb with minimal effort—just follow the timing.

In a large mixing bowl, combine the 0.5 cup active sourdough starter, 4 cups all-purpose flour, 0.5 cup whole wheat flour, 0.25 cup granulated sugar, 1.5 tsp salt, and 0.25 tsp instant yeast. Mix just until the dry ingredients are evenly distributed—don’t overwork the dough yet. The goal here is to create a rough shaggy mass, not a smooth ball.

Cut in the 0.5 cup cold unsalted butter using a pastry cutter or your fingers, breaking it into small pea-sized pieces. The butter should remain cold and cubed throughout the mixing process—this ensures maximum flavor development and a tender crumb. Once incorporated, add 1.5 cups room-temperature water and mix by hand until a sticky dough forms. The dough will be shaggy and wet at this stage, but that’s exactly what we want for Anna Olson’s signature texture.

Transfer the dough to a lightly floured surface and knead for 8-10 minutes by hand. You’re aiming for a smooth, elastic dough that springs back slowly when poked. This step develops gluten, which gives the bread its structure and chew. If the dough feels too sticky, wet your hands slightly to prevent tearing—this is normal with a high-hydration dough.

Here’s the thing—this dough is intentionally sticky. That’s how you get that soft, pillowy interior. Once the dough passes the windowpane test (when you stretch a small piece and it’s thin enough to see light through without tearing), it’s ready for the next step. If it’s still too rough, knead another minute or two. The goal is a dough that feels like wet velvet, not dry and crumbly.

Place the dough in a lightly greased bowl, cover it with a damp kitchen towel, and let it rise at room temperature (70-75°F) for 4 hours. This bulk fermentation is where the magic happens—the dough will nearly double in size and develop those beautiful air pockets. Don’t rush this step; patience here ensures a light, airy crumb later.

After 2 hours, give the dough a gentle fold to redistribute the gluten and strengthen the structure. To do this, 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 on all four sides. This simple technique prevents a dense crumb and encourages even fermentation. The dough should feel slightly firmer after folding but still soft and sticky.

Lightly flour a clean surface and turn out the dough. Gently shape it into a round loaf by pulling the edges toward the center and tucking them under. This technique, called a "boule," creates a tight, even shape that bakes evenly. Place the shaped dough on a piece of parchment paper, seam-side up, and cover it loosely with plastic wrap.

Refrigerate the dough for 12 hours to allow for a slow, cold proof. This extended proofing time is key to Anna Olson’s method—it enhances flavor development and creates that signature crispy crust. The dough will rise slowly in the fridge, and you’ll notice it has puffed up noticeably by morning. The cold proof also makes scoring easier later; the dough will hold its shape better when you slice it before baking.

Preheat your oven to 425°F with a Dutch oven inside for 45 minutes. This step is crucial—it creates the perfect environment for steam, which gives the bread its signature crispy crust. Remove the Dutch oven from the oven and carefully transfer the dough, still on its parchment paper, into the hot pot. Sprinkle the top with 0.25 cup cornmeal and score the dough with a sharp razor blade in a simple cross pattern.

Bake the bread covered for 30 minutes, then remove the lid and bake for another 15-20 minutes until the crust 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 it cool on a wire rack for at least 1 hour before slicing—this allows the crumb to set and prevents a gummy texture. The result? A loaf with a shatteringly crisp crust and a soft, airy interior that’s perfect for sandwiches or toast.

Storing and reheating this recipe

Room-Temp Storage

Your freshly baked loaf stays fresh for 2-3 days at room temperature when wrapped in a clean kitchen towel or stored in a paper bag. The towel method preserves moisture better than plastic—it mimics bakery conditions.

I place my loaf on a wire rack inside a bamboo steamer basket to maintain airflow while keeping it covered. Avoid refrigerating unless necessary, as cold temperatures accelerate staling. 🌾

Refrigerator Life

If you must refrigerate, slice the loaf first and store it in an airtight container with a slice of apple or lemon to prevent drying. It’ll keep for 5-7 days, though the crust loses crispness.

For best quality, reheat slices wrapped in foil in a 350°F oven for 5-7 minutes—this restores moisture without overcooking. I find toasting stale slices in a cast-iron skillet over medium heat works wonders too. ⏰

Freezer Preservation

For long-term storage, slice the bread and freeze on a baking sheet for 1 hour before transferring to a quart-sized freezer bag. This prevents slices from sticking. Frozen bread maintains quality for up to 3 months.

To reheat, toast directly from frozen in a toaster or warm in the oven at 300°F for 10 minutes. I’ve found that wrapping slices in parchment paper before freezing preserves texture better than plastic wrap. ❄️

Reviving Stale Bread

Got a loaf that’s lost its crunch? The steam method works like magic. Place slices in a steamer basket over boiling water for 5-8 minutes—the steam will restore moisture and softness. For extra flavor, brush with melted butter and sprinkle with flaky sea salt before serving.
