This 2-day sourdough bread recipe transforms simple flour and water into a loaf with a crispy crust and airy crumb—no yeast required. The secret lies in the 48-hour fermentation, where wild yeast and bacteria develop complex flavors and structure. I’ve perfected this method after years of experimentation, ensuring reliable results even for beginners.
The process begins with a live sourdough starter, which acts as your natural leavening agent. After feeding it for 24 hours, you’ll shape the dough, let it rise overnight, and bake it the next day for a loaf with tangy depth and an irresistible crunch. The key techniques—proper hydration, bulk fermentation, and scoring—make all the difference.
By the time you pull that golden-brown loaf from the oven, you’ll have a restaurant-quality sourdough with a crisp exterior and a soft, open crumb. The aroma alone will have everyone asking for seconds. This recipe is designed to be foolproof, with clear steps to avoid common pitfalls like dense bread or flat loaves.
Whether you’re a baking novice or an experienced home baker, this method delivers consistent results every time. The best part? Once you master it, you’ll never buy store-bought sourdough again. Let’s get started on your first loaf!
Ingredients for 2 day sourdough bread
Four key ingredients transform simple flour into restaurant-quality sourdough in 48 hours.
| Ingredient | Amount | Notes |
|---|---|---|
| Unbleached Bread Flour 🌾 | 3 ½ cups | High-protein for structure |
| Filtered Water 💧 | 2 ¼ cups | Room temperature preferred |
| Active Sourdough Starter 🍞 | ½ cup | 100% hydration, bubbly |
| Sea Salt 🧂 | ¾ tsp | Fine grain preferred |
| White Vinegar 🍶 | 1 tbsp | For starter feeding |
| Granulated Sugar 🍚 | ¼ tsp | For starter feeding |
| Cornmeal 🌽 | ¼ cup | For dusting dough |
| Olive Oil 🫒 | 1 tbsp | For bowl coating |
| Rice Flour 🌾 | 2 tbsp | For scoring pattern |
The bread flour is non-negotiable here—look for King Arthur or Caputo if you want that professional texture. Bulk bins at Whole Foods often have great options, but check the protein content (12-14%). The starter is your secret weapon: 100% hydration means equal parts flour and water by weight. If yours isn’t bubbly after 24 hours, feed it again with equal parts flour and water—this recipe assumes an active starter. For the flour, store in airtight containers away from light to prevent rancidity.
No sourdough starter? Beginner’s starter kits from King Arthur make it easy, or you can capture wild yeast from flour and water over 5-7 days. The white vinegar and sugar are just for feeding—skip them if your starter’s already active. Running low on bread flour? All-purpose flour works in a pinch, but expect slightly less structure. The sea salt should dissolve completely into the water before mixing—Diamond Crystal kosher is my go-to for even distribution. For scoring, rice flour creates crispy edges without sticking to your lame.
Flour keeps indefinitely in the pantry, but starter needs daily feeding if you’re not baking. The cornmeal and rice flour both last 6-12 months unopened. Once baked, your loaf stays fresh 3-4 days at room temperature, wrapped in a clean kitchen towel. For longer storage, freeze slices between parchment paper—3 months max. Pro tip: Score immediately before baking to prevent overproofing while you preheat the oven.

Step-by-step instructions for perfect 2-Day sourdough bread
This method delivers professional-quality sourdough with an open crumb and tangy flavor every time.
Mix the Starter and Feed for 24 Hours
In a clean bowl, combine the 0.5 cup active sourdough starter, 1 tbsp white vinegar, and 0.25 tsp granulated sugar. The vinegar and sugar create an acidic environment that strengthens the starter’s fermentation. Add 1 cup of the 2.25 cups filtered water and 1 cup of the 3.5 cups unbleached bread flour, mixing until smooth. Cover loosely with a damp towel and let sit at room temperature.
After 4 hours, feed it again with another 1 cup water and 1 cup flour, mixing well. This feeding schedule ensures vigorous fermentation. By the next day, your starter should have doubled in size with plenty of bubbles—this indicates it’s ready for dough. If it’s sluggish, give it one more 4-hour feed before proceeding. The starter should smell slightly tangy and sweet, not harsh or alcoholic.
Autolyse and Develop the Dough
In a large bowl, combine the 3.5 cups unbleached bread flour and the remaining 0.25 cups filtered water (from your original 2.25 cups). Mix with your hands until no dry bits remain—this is called an autolyse. Let it rest for 30 minutes at room temperature. This initial hydration helps develop gluten without exhaustion.
After resting, add the fed starter, 0.75 tsp sea salt, and 1 tbsp olive oil to the bowl. Using a dough scraper, fold the dough over itself 4-5 times to distribute everything evenly. Cover and let rest for another 30 minutes. This step ensures even salt distribution and oil incorporation, which prevents dryness in the final loaf.
Bulk Fermentation with Strategic Folds
Perform a series of stretch-and-folds every 30 minutes for 2 hours. Wet your hands and grab one side of the dough, stretch it upward, and fold it over itself. Rotate the bowl and repeat this motion 4-5 times per session. This builds gluten structure while preventing overworking. The dough should become smoother and more elastic with each fold.
After the final fold, let the dough rest uncovered for 15-30 minutes at room temperature. It should rise noticeably, with bubbles forming on the surface. This is your signal that fermentation is active. The dough should feel slightly puffy but still have some resistance when poked—this indicates it’s ready for shaping.
Shape and Final Proof
Lightly dust a work surface with 0.25 cup cornmeal and turn out the dough. Gently shape it into a round boule by pulling the edges toward the center while rotating the dough. The tension on the surface creates that signature sourdough crust. Place the shaped dough seam-side up in a well-floured banneton or bowl, cover, and refrigerate for 12-16 hours.
Cold fermentation slows yeast activity, allowing flavors to develop fully. The dough should rise noticeably but not double in size. When ready, it should spring back slowly when poked—a sign of proper gluten development. This cold proof also makes scoring easier later.
Score and Bake to Crusty Perfection
Preheat your oven to 475°F with a Dutch oven inside for 45 minutes. Turn out the dough onto a piece of parchment paper, dusted with 2 tbsp rice flour. Using a sharp razor or lame, score the dough with a ½-inch deep diagonal cut—this controls expansion and creates that beautiful oven spring. Transfer the dough (with parchment) into the hot Dutch oven.
Bake covered for 20 minutes, then remove the lid and bake for another 20-25 minutes until the crust is deep golden brown and sounds hollow when tapped. The internal temperature should reach 205-210°F. Let cool on a wire rack for at least 1 hour before slicing—this allows steam to escape and prevents a gummy crumb.
Pro Tips For Making 2 Day Sourdough Bread
- WEIGH YOUR FLOUR: I learned this the hard way—using volume measurements for bread flour leads to inconsistent results. For a 2-day sourdough, weigh your 500g flour to the gram (give or take 2g) so the hydration stays predictable. The starter’s behavior changes with even small flour variations.
- STRETCH AND FOLD AT 72°F: Your kitchen’s temperature matters more than you think. Aim for 72°F (22°C) during bulk fermentation—any warmer, and the dough overproofs in a hurry; cooler, and it drags. Use a digital thermometer if your kitchen swings wildly, and resist the urge to rush the first 2 hours.
- SALT THE DOUGH EARLY: Adding sea salt at the very end? You’re missing the magic. Mix it in with the flour at the start—it starts breaking down gluten immediately, giving you a tighter, more extensible dough by final proof. (Yes, even if you’re impatient like me.)
- USE VINEGAR TO TEST STRENGTH: Your starter’s readiness isn’t just about float tests. Add 1 tsp white vinegar to 1 tbsp starter—if it bubbles vigorously within 5 minutes, it’s strong enough for the 2-day schedule. Weak starter? Feed it one last time with extra flour to boost its confidence before mixing.
Troubleshooting this dish
Dense Dough Issues
If your dough feels heavy or dense after bulk fermentation, you likely underdeveloped the gluten or overproofed it. I’ve found that skipping the autolyse or doing too few stretch-and-folds weakens structure—aim for 4-5 folds every 30 minutes for 2 hours. Also, check your starter: if it’s sluggish (not bubbly after 24 hours), feed it one more time before mixing into the dough. Cold proofing helps too—12-16 hours in the fridge strengthens gluten without overfermenting. 🔥
Flat or Underproofed Loaf
A flat loaf usually means the dough didn’t rise enough during proofing. First, verify your starter is active—it should double in size with bubbles after 24 hours. If it’s weak, feed it extra flour (1:1 ratio) and wait another 4 hours. During bulk fermentation, let the dough rise uncovered for 15-30 minutes before shaping—this helps it expand properly. Also, ensure your Dutch oven is hot enough (475°F) before baking, as steam is key for oven spring. A loaf that’s still soft after baking often needs 5-10 more minutes in the oven.
Sticky or Gummy Crumb
Gummy bread usually stems from overhydration or underbaking. Double-check your water-to-flour ratio—I use 64% hydration (2.25 cups water for 3.5 cups flour) for reliable results. If your dough feels too sticky, add 1-2 tbsp extra flour during bulk fermentation. For baking, ensure the oven reaches 475°F and bake until the internal temp hits 205-210°F. Let the loaf cool at least 1 hour before slicing—rushing this step traps steam, keeping the crumb moist. 💫
Crust Too Dark or Burnt
If your crust burns before the interior cooks, your oven runs too hot or the loaf is too close to the heating element. I recommend baking on the middle rack and covering the loaf with foil after 20 minutes if it browns too quickly. For a lighter crust, try reducing oven temp to 450°F for the first 15 minutes, then increasing to 475°F. Also, ensure your Dutch oven has a tight lid—gaps let heat escape, causing uneven browning. A thermometer helps monitor oven temp accurately.
Dough Collapses After Scoring
Collapsed dough often means the gluten wasn’t strong enough or the dough was overproofed. Strengthen gluten by adding 1 extra set of stretch-and-folds during bulk fermentation. For scoring, use a sharp razor or lame and cut ½-inch deep—shallow scores won’t control expansion. If the dough collapses after baking, it may have overproofed during cold fermentation. Reduce fridge time to 10-12 hours and check for a slow spring-back when poked before baking. ⚡

Frequently asked questions
Why does this recipe take 2 days instead of 1?
The extra day allows for a slower, more controlled fermentation that develops deeper flavor and better gluten structure. The first 24 hours focuses on building your starter, while the cold proof in the fridge (12-16 hours) enhances flavor complexity and makes scoring easier. This method produces a more open crumb and tangy taste than quick sourdough recipes.
Can I use all-purpose flour instead of bread flour?
Yes, but expect slightly less structure in your final loaf. Bread flour’s higher protein content (12-14%) creates stronger gluten, while all-purpose (10-12%) works fine for a softer crumb. For best results, use King Arthur or Caputo bread flour if you want that professional texture. If substituting, add 1 extra tbsp flour during bulk fermentation to compensate for lower protein.
What if my starter isn’t bubbly after 24 hours?
Give it one more 4-hour feed with equal parts flour and water (1:1 ratio). If it’s still sluggish, try moving it to a warmer spot (like near your oven with the light on) to encourage activity. A weak starter often means the dough won’t rise properly—this is why we feed it twice before using it in the recipe. The starter should smell slightly tangy and sweet, not harsh or alcoholic.
Do I really need a Dutch oven for this?
A Dutch oven is ideal because it traps steam, creating that perfect oven spring and crispy crust. If you don’t have one, use a heavy oven-safe pot with a tight lid or bake on a pizza stone with a metal bowl inverted over the loaf. Just be prepared for a slightly less crisp exterior. The key is maintaining high heat (475°F) and steam for the first 20 minutes of baking.
How can I tell when the bread is fully baked?
Your loaf is done when the internal temperature reaches 205-210°F and the crust is deep golden brown. Tap the bottom—it should sound hollow. If it’s still soft after 45 minutes, bake for another 5-10 minutes with the lid off. The crust will continue to crisp as it cools. Never rely on color alone—many ovens run hot or cold, so always check the internal temperature.
