Ingredients
- 25 oz All-Purpose Flour (for the starter mixture)
- 24.75 oz Whole Wheat Flour (for the starter mixture)
- 5.33 oz Water (room‑temperature, for initial starter)
- 2 oz Water (per daily feeding (10‑14 days))
- 2 oz Starter (portion of mature starter used for each feeding)
- 2.5 oz Flour Mixture (per daily feeding – same ratio of all‑purpose to whole‑wheat as starter mixture)
- 3 oz Active Sourdough Starter (mature starter, ready to bake)
- 12.67 oz Water (room‑temperature, for dough)
- 18.33 oz King Arthur All-Purpose Flour (higher protein, can substitute bread flour)
- 1.75 tsp Salt (fine sea salt)
- 1 spray Cooking Spray (for parchment paper)
- 3 cup Boiling Water (creates humid environment in turned‑off oven)
- 2 tbsp Softened Salted Butter (optional, for serving)
Instructions
Create Initial Starter Mixture
Weigh 25 oz all‑purpose flour and 24.75 oz whole‑wheat flour into a bowl. Add 5.33 oz water and 5 oz of the flour mixture, stir with a wooden spoon until no dry spots remain.
Time: PT5M
Cover and Ferment Starter
Cover the bowl tightly with plastic wrap and let sit at room temperature for 48–72 hours until it becomes bubbly and smells mildly alcoholic.
Time: PT72H
Temperature: 70°F
Daily Feedings (10–14 Days)
Each day, discard all but 2 oz of the starter. Add 2 oz water, 2 oz starter, and 2.5 oz of the flour mixture. Stir until smooth and cover again.
Time: PT14D
Temperature: 70°F
Mix Dough
In a large bowl, combine 3 oz mature starter with 12.67 oz water; whisk to dissolve. Add 18.33 oz King Arthur all‑purpose flour and 1.75 tsp salt. Stir with a wooden spoon or dough whisk until no dry flour remains; the dough will be shaggy and sticky.
Time: PT10M
Bulk Fermentation
Cover the bowl with plastic wrap and let the dough rest at room temperature for 12–18 hours, or until it has roughly doubled in size.
Time: PT18H
Temperature: 70°F
Shape and Light Knead
Lightly flour a clean work surface. Turn the dough out, dust with a little flour, and perform 10–15 gentle stretch‑and‑fold motions to tighten the surface tension.
Time: PT10M
Prepare Dutch Oven and First Rise
Line a parchment sheet (12×12 in) with cooking spray. Place the shaped dough on the parchment, cover with plastic wrap, and set it inside a Dutch oven that sits on the middle rack of a turned‑off oven. Place a pan with 3 cups boiling water on the bottom rack to bring the oven temperature to about 95°F. Let rise for 2–3 hours.
Time: PT3H
Temperature: 95°F
Preheat Oven
After the first rise, remove the plastic wrap, set the oven to 425°F, and allow it to preheat for about 10 minutes.
Time: PT10M
Temperature: 425°F
Score the Loaf
Dust the top of the loaf lightly with flour, then use a scoring blade or sharp knife to make a 7‑inch slash about ½ inch deep across the center.
Time: PT5M
Bake with Lid
Place the Dutch oven (with lid on) into the preheated oven and bake for 30 minutes.
Time: PT30M
Temperature: 425°F
Bake Uncovered
Remove the lid and continue baking for an additional 25 minutes, or until the internal temperature reaches 210°F and the crust is deep golden‑brown.
Time: PT25M
Temperature: 425°F
Cool the Bread
Transfer the loaf to a wire rack and let cool completely (about 2 hours) before slicing.
Time: PT2H

Critical Steps — Do Not Skip
- Creating and maintaining a healthy starter (steps 1‑3).
- Ensuring the dough doubles in bulk fermentation (step 5).
- Scoring the loaf before the final bake (step 9).
- Baking with a lid to trap steam, then finishing uncovered (steps 10‑11).
Chef Tips from the Video
- Use a kitchen scale for all measurements; weight is far more reliable than volume for bread.
- If you don’t have a Dutch oven, place a heavy cast‑iron pot with a tight‑fitting lid inside a preheated oven.
- For extra flavor, add a tablespoon of honey or malt syrup to the dough during mixing.
Troubleshooting
Starter does not become bubbly after 72 hours.
Make sure the starter is kept at a warm room temperature (70‑75°F) and that you are feeding it with equal parts flour and water by weight.
Dough does not rise during bulk fermentation.
Check that the starter is active (it should double within 8‑12 hours after feeding). If not, give it more feedings or a warmer environment.
Crust is pale and hard.
Ensure the oven is preheated to 425°F and bake with the lid on for the full 30 minutes to trap steam.
Bread collapses after scoring.
Score the loaf just before baking and make sure the dough has fully doubled in size; under‑proofed dough will not hold its shape.
Storage
Refrigerator: Wrap tightly in plastic or store in a bread box for up to 5 days.
Freezer: Slice, wrap each piece in foil, and freeze for up to 3 months.
Room temperature: Best consumed within 24 hours; keep in a paper bag or bread box.
Make-Ahead Tips
- The starter can be kept in the refrigerator and fed weekly for long‑term storage.
- After shaping, the dough can be refrigerated for a cold retard (up to 24 h) to develop more flavor.
- Freeze the baked loaf (sliced) for later use; re‑heat in a 350°F oven for 10 minutes.
Frequently Asked Questions
What is the cultural significance and history of sourdough bread in American cuisine?
Sourdough bread dates back to the Gold Rush era when miners relied on natural leavening to bake sturdy loaves on the frontier. In America it became a symbol of self‑reliance and artisanal baking, especially in San Francisco where the famous "San Francisco sourdough" style emerged.
What are the traditional regional variations of sourdough bread in the United States?
The most famous U.S. variation is San Francisco sourdough, known for its tangy flavor from local wild yeasts. Other regions, like the Pacific Northwest, often incorporate whole‑grain flours, while New York bakeries may add a touch of malt for a milder taste.
How is sourdough bread traditionally served in American households?
In the United States, sourdough is typically sliced and served toasted with butter, used for sandwiches, or paired with soups and stews. It’s also a popular base for avocado toast and bruschetta.
What occasions or celebrations is sourdough bread traditionally associated with in American culture?
While not tied to a specific holiday, sourdough loafes are often baked for family gatherings, weekend brunches, and as a comforting staple during colder months. Many home bakers also make sourdough for Thanksgiving to accompany turkey and gravy.
What makes this no‑knead sourdough bread special in the context of American home baking?
The recipe eliminates the labor‑intensive kneading step, relying on a long fermentation to develop gluten. This makes artisan‑quality sourdough accessible to home cooks who may lack a stand mixer, while still delivering a crisp crust and open crumb.
What are the most common mistakes to avoid when making no‑knead sourdough bread at home?
Common errors include under‑feeding the starter, using water that’s too cold (which slows fermentation), and over‑proofing the dough so it collapses. Also, failing to create steam in the oven will result in a dull crust.
Why does this recipe use a Dutch oven instead of a regular baking sheet?
A Dutch oven traps steam and creates a mini‑oven environment, which mimics professional steam‑injected ovens. This yields a glossy, crackly crust and better oven spring compared to baking on a sheet without steam.
Can I make the sourdough loaf ahead of time and how should I store it?
Yes. After baking, let the loaf cool completely, then wrap it tightly in plastic or store it in a bread box for up to five days. For longer storage, slice and freeze the bread; re‑heat in a 350°F oven before serving.
What texture and appearance should I look for when the no‑knead sourdough bread is done?
The crust should be deep golden‑brown with a glossy finish, and the loaf should have a pronounced “ear” where it was scored. An internal temperature of 210°F and a hollow sound when tapped on the bottom indicate it’s fully baked.
What does the YouTube channel America's Test Kitchen specialize in?
The YouTube channel America's Test Kitchen specializes in scientifically tested, fool‑proof recipes and detailed cooking technique videos that help home cooks achieve reliable results.
How does the YouTube channel America's Test Kitchen's approach to sourdough baking differ from other baking channels?
America's Test Kitchen emphasizes precise measurements, controlled fermentation times, and equipment‑agnostic methods (like the no‑knead technique) whereas many other channels focus on visual flair or high‑tech gadgets.
