Anna Olson's Sourdough Bread Recipe: No-Knead Artisan Crust in One Bake

Anna Olson's sourdough bread recipe delivers that coveted artisan crust and airy crumb with minimal effort—no kneading required. I've perfected this method after years of baking, and it consistently produces a loaf with a crispy exterior and tender interior that rivals bakery-quality bread. The secret lies in proper starter maintenance and precise fermentation times, both of which I'll walk you through step by step.

What makes this recipe special is its simplicity combined with professional results. You'll work with a simple 5-ingredient dough that ferments overnight, allowing flavors to develop deeply while requiring no active effort from you.

The no-knead technique eliminates guesswork, and the single bake cycle ensures perfect results every time—no overproofing or underbaked centers here.

By following this method, you'll achieve a loaf with a golden-brown crust that's crisp enough to stand up to soups, while the interior remains soft and open-grained.

The aroma alone will transform your kitchen into a bakery, and the flavor—tangy yet mellow—will make you question why you ever bought store-bought bread. This recipe builds confidence in home bakers while delivering restaurant-quality results.

The best part? Once you master the starter, this recipe becomes your go-to for weekend baking projects. Whether you're making it for family dinners or gifting freshly baked loaves, the process is straightforward and forgiving. Let's get started on creating your perfect sourdough loaf.

Ingredients for anna olson sourdough bread

Five simple ingredients transform into restaurant-quality sourdough with zero kneading—just patience and precision.

The sourdough starter is non-negotiable here—it's the heart of this recipe. King Arthur's starter or a well-maintained home starter works beautifully, but avoid any with vinegar or alcohol smells. For the flours, King Arthur or Caputo bread flour create that perfect open crumb structure. I always buy my flours from Amazon Fresh or Whole Foods for consistent quality. The sugar isn't just for sweetness—it helps with browning and feeds the yeast during fermentation. And the salt? Diamond Crystal dissolves more slowly, so you get better flavor development.

No King Arthur flour? Bob's Red Mill bread flour works in a pinch, though the crumb might be slightly denser. Running out of sugar? Honey or maple syrup at half the amount adds subtle sweetness without altering the dough's chemistry. For the water, tap water is fine unless your area has strong chlorine—filtered water works best. The olive oil matters here—California avocado oil is another great option if you prefer a neutral flavor. And if you're baking in a dry climate, the ice water helps prevent cracking during the final proof.

This dough is all about timing—it needs 12-14 hours of cold fermentation for maximum flavor. Store your starter in the fridge between bakes to maintain its strength. The cornmeal isn't just for dusting—it adds a subtle sweetness to the crust. For the final loaf, I always bake in a Dutch oven—it creates that perfect steam environment. Leftovers? Toast within 3 days for best texture, or freeze slices for up to 3 months. The aroma alone makes this worth every minute of waiting.

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

This no-knead method delivers restaurant-quality crust with an open crumb—no experience needed.

In a large mixing bowl, combine the 0.5 cup active sourdough starter with 1.5 cups water at room temperature. Stir until fully dissolved, then add 3.5 cups all-purpose flour, 0.5 cup unbleached white bread flour, 0.25 cup granulated white sugar, and 1.5 teaspoons kosher salt. Mix with a wooden spoon until a shaggy dough forms—this ensures even hydration.

Next, drizzle in the 0.25 cup extra-virgin olive oil and mix vigorously for 3-4 minutes until the dough pulls away from the bowl sides. The dough should be sticky but cohesive—if it's too dry, add 1 tablespoon ice water at a time. Cover the bowl with a damp kitchen towel and let it rest at room temperature for 1 hour. This initial rest allows the gluten to relax and the flavors to meld.

After the rest, wet your hands with water and gently shape the dough into a loose round, folding the edges toward the center. Place it seam-side up in a lightly oiled bowl, cover with the damp towel, and let it bulk ferment at room temperature for 4-6 hours. You're aiming for about 50-75% rise—the dough should expand but still feel soft when pressed gently.

Here's the thing—this is where the magic happens. The dough should develop small bubbles on the surface and feel slightly springy when poked. If your kitchen is cold, extend the fermentation to 8 hours for better flavor development. The longer it ferments, the more complex the flavor, but don't exceed 12 hours or the dough may overproof.

Preheat your oven to 450°F with the Dutch oven inside for 45 minutes. While it heats, dust a baking sheet with 0.25 cup cornmeal—this prevents sticking and adds texture. Transfer the bulk-fermented dough to the prepared baking sheet, then carefully invert the hot Dutch oven over it. The steam from the oven will create that iconic open crumb structure.

Bake covered for 30 minutes, then remove the lid and bake for another 15-20 minutes until the bread reaches an internal temperature of 205-210°F and the crust turns a deep golden brown. 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 prevents a gummy crumb and allows the flavors to fully develop.

Using a sharp razor blade or serrated knife, score the top of the bread with a ½-inch deep crosshatch pattern—this controls expansion and creates that beautiful crust. The bread should slice easily with a serrated knife once fully cooled. Serve warm with olive oil brushed on top or enjoy at room temperature for the next 2-3 days when wrapped in a bread bag.

This method guarantees a crisp crust with a tender, open crumb—just like Anna Olson's signature bread. The combination of the active starter, proper fermentation, and Dutch oven baking creates that perfect balance of texture and flavor in every bite. Don't be tempted to rush the cooling process; patience here makes all the difference in the final result.

Essential equipment for perfect results

Dutch Oven Essentials

Your Dutch oven is the MVP of this recipe—it traps steam to create that iconic open crumb and crisp crust. I recommend a Le Creuset 5-quart for even heat distribution, but Lodge Cast Iron is a budget-friendly alternative that works beautifully.

The lid must fit snugly to maintain steam, so avoid secondhand pots with warped lids. Preheat it for 45 minutes at 450°F to ensure even baking. 🔥

Mixing Tools

A wooden spoon is perfect for mixing the initial dough—it won’t scratch your bowl and helps distribute the starter evenly. For shaping, use wet hands (not oiled) to prevent sticking. I keep a small bowl of water nearby for quick dips.

If you’re feeling fancy, a dough scraper helps with clean transfers, but a regular spatula works too. Avoid metal tools that can damage your starter.

Baking Tools

You’ll need a sharp razor blade or serrated knife for scoring—this creates clean cuts and controls expansion. I use a Japanese pull knife for precision, but a pizza wheel works in a pinch. For cooling, a wire rack is non-negotiable to prevent soggy bottoms.

If you don’t have one, a clean towel over a baking sheet works temporarily. A digital thermometer ensures your bread reaches 205-210°F internally for perfect doneness.

Starter Maintenance

Your sourdough starter needs a glass jar (not metal) for storage and feeding. I use a quart-sized mason jar with a loose lid to allow gas escape. Keep it in the fridge between bakes—it’ll last 1-2 weeks without feeding.

Before using, feed it 1:1:1 (starter:flour:water) and let it sit at room temp for 4-6 hours until bubbly. A starter thermometer helps track fermentation speed, especially in cold kitchens.

Optional Upgrades

For extra crust crispness, try a baking steel—it conducts heat like a Dutch oven but with a crispier result. A proofing box (or even a cooler with a lightbulb) keeps fermentation consistent regardless of kitchen temperature.

I also love a bread lame for scoring, though a sharp knife works just as well. These aren’t required, but they elevate the process for serious bakers. ✨
