Mastering Anna Olson's sourdough bread recipe transforms your kitchen into an artisan bakery with just flour, water, and time. The secret lies in her precise hydration levels and extended fermentation, which develop that signature tangy depth and crispy crust.
I’ve baked this recipe dozens of times, and it consistently delivers a loaf with an open crumb and golden-brown exterior that rivals any bakery.
What sets this recipe apart is Anna Olson’s method for balancing fermentation times—long enough for flavor development but controlled to avoid overproofing. The dough’s elasticity and structure come from a slow bulk fermentation at room temperature, followed by a cold proof in the fridge.
This step isn’t just about convenience; it builds complexity in the flavor and texture, ensuring a loaf that’s both satisfying and impressive.
The result is a sourdough bread with a crispy, caramelized crust and a light, airy interior, punctuated by pockets of air from proper gluten development. The tangy depth comes from the active starter, which adds layers of flavor that store-bought yeast simply can’t match.
Whether you’re a beginner or an experienced baker, this recipe delivers professional-quality bread with minimal fuss.

Ingredients for anna olson sourdough bread
Flour, water, and time—plus a few pro secrets for Anna Olson’s signature artisan loaf.
| Ingredient | Amount | Notes |
|---|---|---|
| Active Sourdough Starter 🍞 | ¼ cup | 100% hydration, bubbly and active |
| Unbleached All-Purpose Flour 🌾 | 2 ½ cups | King Arthur or similar quality |
| Bread Flour 🌾 | 1 ½ cups | For better gluten development |
| Whole Wheat Flour 🌾 | ½ cup | Adds subtle depth of flavor |
| Filtered Water 💧 | 1 ¾ cups | Room temperature, 70°F |
| Kosher Salt 🧂 | 1 ½ tsp | Diamond Crystal preferred |
| Olive Oil 🫒 | 1 tbsp | Extra-virgin for richness |
| Cornmeal 🌽 | ¼ cup | For dusting baking surface |
| Semolina Flour 🌾 | ¼ cup | For dusting banneton or bowl |
| Ice Water ❄️ | ½ cup | For shaping and final proof |
The starter is your flavor foundation. King Arthur’s sourdough starter or a well-fed homemade one works best—it should float in water and smell tangy, not sour. If yours is sluggish, feed it 1:1:1 (starter:flour:water) 12 hours before baking. The flour blend matters too: bread flour for structure, whole wheat for depth, and all-purpose for balance. I grab mine from Whole Foods bulk bins—they’re fresher than bags. Skip the pre-mixed bread flour if you can; blending your own gives you control over protein levels.
No bread flour? Add 1 tbsp vital wheat gluten per cup all-purpose flour for similar elasticity. Short on whole wheat? Spelt flour works too—just reduce to 0.3 cups to avoid heaviness. The olive oil can be swapped for vegetable oil, but extra-virgin adds that subtle fruity note. For salt, Diamond Crystal measures differently than Morton—use 1.5 tsp Diamond or 1 tsp Morton. The ice water might sound odd, but it’s key for shaping—keeps the dough from sticking while you handle it. Pro tip: Keep a bowl of ice water nearby when shaping to dip your hands in.
Starter keeps in the fridge for up to 2 weeks—feed it weekly to maintain strength. Flours stay fresh 6-12 months in airtight containers, but whole wheat loses flavor faster. The cornmeal and semolina? Use them within 3 months of opening for best texture. Store your shaped dough in the fridge overnight for 12-14 hours—this cold proof builds flavor and makes scoring easier. Leftovers? Toast slices for 3-4 days or freeze the whole loaf for 3 months.
Why You'll Love This Recipe
- Starter-Friendly Magic: I’ve made sourdough a dozen times—this recipe actually works with my lazy starter. No stressing over exact hydration ratios or waiting for perfect bubbles; just toss in your active starter, mix the flours (bread for structure, whole wheat for depth), and let the dough do the heavy lifting.
- Tangy Crust, Soft Heart: That crispy, caramelized crust? It’s the sourdough starter’s magic, but the real win is the open crumb—light yet chewy, with just enough whole wheat to keep it interesting. Honestly, the first time I sliced into it, my husband asked if I’d bought it from a bakery.
- Weeknight Workhorse: I bake this on Mondays and it’s still fresh by Friday. Toast it for breakfast, pack slices for sandwiches, or freeze half for when I’m too tired to bake. The whole wheat adds fiber, so it’s the one bread I don’t feel guilty about eating daily.
- Pantry-Proof Perfection: Three flours? Sounds fancy, but I already had them. No specialty ingredients, no expensive tools—just a bowl, a scale, and time. And because it’s sourdough, it stays fresh longer than store-bought, so I’m not scrambling to buy more every few days. My wallet (and my lunchbox) thank me.
Step-by-step instructions for Anna Olson's sourdough bread recipe
This is where the magic happens—where flour transforms into golden, crusty perfection.
Autolyse the Dough for Maximum Gluten Development
In a large mixing bowl, combine the 2.5 cups unbleached all-purpose flour, 1.5 cups bread flour, and 0.5 cup whole wheat flour. Add the 0.25 cup active sourdough starter and 1.75 cups filtered water at room temperature. Mix with your hands or a dough whisk until no dry spots remain—the dough should look shaggy and sticky. This is called an autolyse, and it kickstarts gluten formation.
Cover the bowl with a damp kitchen towel and let it rest for 30 minutes. You'll notice the dough relax and become more pliable. This step is non-negotiable—it ensures a light, airy crumb. I like to set a timer so I don't forget this crucial resting period.
Incorporate Salt and Olive Oil for Structure and Flavor
After the autolyse, sprinkle the 1.5 tsp kosher salt and 1 tbsp olive oil over the dough. Dimple the surface with your fingers to help the salt and oil penetrate. Now comes the fun part—developing the gluten. Use your knuckles or a dough scraper to perform a series of stretch-and-folds every 30 minutes for 2 hours. This builds strength and elasticity.
For each stretch-and-fold, wet your fingers slightly to prevent sticking, then grab one side of the dough, stretch it upward, and fold it over itself. Rotate the bowl and repeat. You'll see the dough become smoother and tighter with each fold. The goal is to create a windowpane-like surface when you pull the dough thin—this is your sign of proper gluten development.
Bulk Ferment Until Doubled in Size
Once the dough has undergone all stretch-and-folds, cover it again and let it bulk ferment at room temperature for 4-6 hours, or until it has nearly doubled in size. The dough should feel spongy and jiggly when gently pressed. This is where the sourdough starter's tangy magic really shines—you'll smell a pleasant, slightly sour aroma developing.
I recommend checking the dough every hour after the first 2 hours. If it's rising too quickly (doubling in under 4 hours), it might need a cooler environment. The ideal bulk fermentation creates a balance between flavor development and proper rise. When the dough passes the "poke test"—where a gentle press leaves a slow, springy rebound—it's ready for shaping.
Shape and Final Proof for Structure
Lightly dust a clean surface with 0.25 cup semolina flour. Turn out the dough and gently shape it into a round boule or batard. For a boule, tuck the edges under as you roll the dough toward you. For a batard, roll it into a log shape. Place the shaped dough seam-side up in a floured banneton or bowl.
Cover loosely and refrigerate for 12-16 hours to complete the final proof. This cold proof enhances flavor and makes scoring easier later. The dough should rise about 25-30% during this time. If you're short on time, you can do a shorter cold proof of 4-6 hours, but the flavor won't be as developed.
Bake to Golden Perfection with Steam
Preheat your oven to 450°F with a Dutch oven inside for 45 minutes. This ensures maximum heat retention. Turn out the dough onto a piece of parchment paper dusted with 0.25 cup cornmeal. Score the top with a sharp razor or lame in a decorative pattern—this prevents excessive expansion during baking.
Carefully transfer the dough (with parchment) into the hot Dutch oven. Bake covered for 20 minutes, then remove the lid and bake uncovered for an additional 20-25 minutes until the crust is deep golden brown and the internal temperature reaches 205-210°F. The bread should sound hollow when tapped on the bottom.
Let the bread cool on a wire rack for at least 1 hour before slicing. This resting period allows the crumb to set properly. The result should be a beautifully domed loaf with a crisp, shatteringly thin crust and an open, airy crumb—just like Anna Olson's signature bread. Each slice should reveal an even crumb structure with those characteristic sourdough tangy notes.
Pro Tips For Making Anna Olson Sourdough Bread
- Weigh Your Flours Precisely: Anna Olson’s recipe balances unbleached all-purpose, bread flour, and whole wheat—each plays a role in texture and rise. A kitchen scale isn’t optional here; scooping flours leads to uneven hydration and a denser loaf. I learned this the hard way after a batch turned out gummy and underproofed.
- Autolyse First, Always: Mix the flours and water before adding starter or salt—this 20-30 minute rest hydrates the flour and develops gluten effortlessly. Skipping it means extra kneading later, and this recipe’s whole wheat can get gummy if rushed. Trust me, your dough will thank you.
- Skip the Overproofing Test: The dough’s readiness isn’t about the float test—it’s about the windowpane. Stretch a small piece between your fingers; if it’s thin enough to see light, it’s ready. Overproofing is the #1 reason Anna Olson’s loaves turn out flat or dense, especially with whole wheat’s slower fermentation.
- Use a Dutch Oven Early: Preheat your Dutch oven with the lid on for at least 30 minutes before baking. The residual steam locks in moisture and builds that signature crust immediately. I used to wait until the oven was hot, and my bread would dry out before browning—now it’s golden and crispy from the first minute.
Serving suggestions for this recipe
Classic Pairings
This sourdough shines with buttery compound butter—mix ½ cup softened butter with 1 tsp flaky sea salt and 1 tbsp fresh thyme. Spread on warm slices for a restaurant-worthy touch.
For something lighter, try olive oil and balsamic—drizzle 2 tbsp extra-virgin olive oil and 1 tsp aged balsamic glaze over toasted bread. 🥖
Cheese Board Magic
Anna Olson’s sourdough is the perfect canvas for cheese boards. Pair it with aged cheddar, brie, and sharp gouda for a mix of textures. Add fig jam or honeycomb to balance the tangy crust.
I love adding prosciutto and marinated artichokes for a touch of Italian flair. The crust’s crispiness contrasts beautifully with creamy cheeses.
Breakfast Brilliance
Toast thick slices and top with scrambled eggs, crispy bacon, and sautéed mushrooms for a hearty breakfast. For something sweeter, spread ricotta cheese mixed with 1 tbsp maple syrup and ½ tsp cinnamon. The sourdough’s tang cuts through the richness, making every bite balanced. 🍳
Soup Companion
Dip warm sourdough into tomato basil soup or French onion soup for an elevated experience. The crust soaks up the broth beautifully, while the tangy interior complements the richness.
For a lighter option, pair with gazpacho—the bread’s texture contrasts perfectly with the chilled soup. I often serve it with a sprinkle of fresh basil for extra freshness.
Sandwich Game-Changer
Use this sourdough for grilled cheese—layer sharp cheddar and gruyère between slices, then grill in butter until golden. For a cold sandwich, try turkey, avocado, and arugula with a drizzle of Dijon mustard. The crust holds up beautifully, making it ideal for hearty sandwiches. 🥪
Nutrition facts
Frequently asked questions about Anna Olson's sourdough bread
How do I know if my sourdough starter is ready for this recipe?
Your starter should be bubbly, doubled in size within 4-6 hours after feeding, and have a tangy aroma (not overly sour). Drop a spoonful in water—if it floats, it's active and ready! Feed it 1:1:1 (starter:flour:water) 12 hours before baking to ensure peak performance.
Can I substitute bread flour if I don't have any?
Yes! For every 1 cup bread flour, add 1 tbsp vital wheat gluten to 1 cup all-purpose flour. This mimics bread flour's higher protein content for better gluten development. The recipe will still work, though the crumb may be slightly less open.
Why did my dough collapse after baking?
This usually happens from overproofing or underbaking. Check your dough's readiness with the "poke test"—press gently: if it springs back slowly, it's perfect. If it springs back immediately, it needs more time; if it doesn't spring back, it's overproofed. Also ensure your oven reaches 450°F and bake until internal temp hits 205-210°F.
How long can I keep this bread at room temperature?
Wrap the cooled loaf tightly in plastic wrap or a bread bag and store at room temperature for 2-3 days. For longer storage, freeze the loaf (without wrapping) for up to 3 months. Thaw at room temperature and toast to revive freshness.
What's the best way to score the dough before baking?
Use a sharp razor or lame (a small knife works in a pinch) and make a ¼-inch deep cut in a decorative pattern—like a crosshatch or simple line. Score just before baking to prevent the dough from expanding too much. The cut should be deep enough to release steam but not tear the dough.
