🤔 What Is Sourdough Bread?

Sourdough is bread leavened by a sourdough starter, a living culture of wild yeast and friendly bacteria, instead of commercial yeast. The starter is simply flour and water that have been left to ferment, then fed regularly to keep it alive and active.

When you mix the starter into dough, the wild yeast produces carbon dioxide, which makes the bread rise. At the same time, the bacteria produce natural acids, which give sourdough its mild tangy flavor and help the bread stay fresh longer than yeasted loaves.

What makes sourdough special?

  • A complex, mildly tangy flavor. Slow fermentation creates depth that quick breads cannot match.
  • A crisp, crackly crust. Baking in a hot, covered Dutch oven traps steam for a gorgeous, blistered crust.
  • A chewy, open crumb. Long fermentation and gentle handling create an airy, tender interior.
  • Good keeping quality. The natural acids slow staling, so sourdough lasts longer on the counter.
  • Simple ingredients. Just flour, water, salt, and starter.

🧂 Ingredient Notes and Smart Substitutions

Active sourdough starter

The starter is the heart of this recipe. An active starter is bubbly, smells pleasantly sour and yeasty, and has about doubled in size a few hours after feeding. This is the stage when it is at its peak and strongest. A sluggish starter leads to a dense, flat loaf, so wait until yours is lively before baking.

How to tell it is ready: The starter should look full of bubbles, domed on top, and airy. A spoonful dropped into water often floats, though that test is not perfect. Use the doubled volume and the bubbles as your main clues.

Starter tip: Feed your starter 4 to 8 hours before you plan to mix the dough, depending on how warm your kitchen is and how fast your starter rises. Use it at or just after its peak.

Warm water

Warm water, around 80 to 85°F (27 to 29°C), encourages steady fermentation. Water that is too hot can harm the culture, and very cold water slows everything down. If you use chlorinated tap water and your starter seems sluggish, try filtered water.

Bread flour

Bread flour has a high protein content, which builds the strong gluten network that sourdough needs to trap gas and hold its shape through a long fermentation. It gives a chewier crumb and a taller loaf than all-purpose flour.

Substitution: All-purpose flour will work, but the dough will be softer and slightly harder to handle, and the loaf may be less tall. You may want to reduce the water by a tablespoon or two. You can also replace up to 1 cup (about 120 g) of the bread flour with whole wheat or rye flour for a heartier, more flavorful loaf. Whole grain flours absorb more water, so add a little extra if the dough feels stiff.

Salt

Salt strengthens the dough, balances the flavor, and slows fermentation slightly. Fine sea salt or kosher salt both work. If you use a coarse salt with a different density, measuring by weight (10 g) is the most accurate method.

👩‍🍳 How to Make Homemade Sourdough Bread: Step-by-Step

Step 1: Prepare the starter

Make sure your sourdough starter is active, bubbly, and approximately doubled in size after feeding. A healthy starter is essential for a good rise. If your starter is not ready, wait a little longer, or feed it again and try the next day.

Step 2: Mix the dough

In a large mixing bowl, combine the sourdough starter and water. Stir until the starter is mostly dissolved and the water looks milky. Add the bread flour and mix until no dry flour remains. The dough will look rough and sticky, and that is perfectly normal at this stage.

Step 3: Rest the dough

Cover the bowl and let the dough rest for 30 to 45 minutes. This resting period, known as the autolyse, allows the flour to absorb the water fully and begins developing gluten without any effort from you. It also makes the dough smoother and easier to handle.

Step 4: Add the salt

Sprinkle the salt over the dough. Wet your hands and gently pinch and fold the dough until the salt is evenly incorporated. You can squeeze the dough between your fingers like a crab claw, then fold it over itself, until you no longer feel any grains of salt.

Step 5: Perform stretch and folds

Over the next 2 hours, perform 4 sets of stretch and folds, approximately 30 minutes apart. To do a set:

  1. With wet hands, grab one side of the dough and gently pull it upward until you feel resistance.
  2. Fold it toward the center.
  3. Rotate the bowl a quarter turn and repeat.
  4. Continue until you have stretched and folded all four sides.

This technique strengthens the dough, builds structure, and traps air without the work of kneading. Cover the bowl between sets. You will notice the dough becoming smoother, stronger, and more elastic with each round.

Step 6: Bulk fermentation

Cover the bowl and let the dough continue rising at room temperature until it looks noticeably larger, airy, and slightly jiggly, with bubbles visible along the sides of the bowl. This may take another 2 to 4 hours, depending on room temperature and starter strength. Look for roughly a 50 to 75 percent increase in volume rather than relying only on the clock.

Tip: Use a clear container, or place a rubber band or piece of tape at the dough’s starting level, so you can measure how much it has grown.

Temperature matters: In a warm kitchen (78 to 80°F or 25 to 27°C), bulk fermentation can be faster. In a cool kitchen, it can take longer. Always judge the dough by its look and feel.

Step 7: Shape the dough

Turn the dough onto a lightly floured surface. Gently shape it into a round loaf by folding the edges toward the center. Flip it seam-side down and use your hands to cup the dough and drag it lightly toward you, creating surface tension. A taut surface helps the loaf rise upward in the oven rather than spread out.

Step 8: Final shaping

Let the dough rest for 15 to 20 minutes, then gently tighten the round shape again if needed. This brief rest relaxes the gluten, making the final shape easier and neater.

Step 9: Cold fermentation

Place the shaped dough seam-side up into a well-floured proofing basket or a bowl lined with a floured kitchen towel. Cover and refrigerate for 8 to 12 hours.

The cold slows the yeast and allows the bacteria to keep producing flavor, creating a more tangy, complex loaf. Cold dough is also easier to score and handle.

Flouring tip: Use rice flour or a mix of rice flour and bread flour in the basket to prevent sticking. Do not be shy with it.

Step 10: Preheat the oven

Place a Dutch oven with its lid inside your oven. Preheat to 450°F (230°C) for at least 30 minutes, so the pot is fully heated. A hot pot is the secret to great oven spring.

Step 11: Score the bread

Carefully remove the hot Dutch oven. Turn the cold dough onto a piece of parchment paper, seam-side down. Use a sharp bread lame or razor blade to make one confident slash across the top, about ½ inch (1 cm) deep.

Scoring tip: A quick, decisive motion at a slight angle works best. A slash gives the loaf a controlled place to expand.

Step 12: Bake covered

Carefully lower the dough with the parchment into the hot Dutch oven. Cover with the lid and bake for 20 minutes. The trapped steam keeps the crust soft and flexible so the loaf can rise fully.

Safety note: The Dutch oven will be extremely hot. Use thick oven mitts, and handle the lid and pot with great care.

Step 13: Bake uncovered

Remove the lid and continue baking for another 20 to 25 minutes, until the crust is deeply golden brown and beautifully crisp. For a darker, more flavorful crust, bake until it is a rich mahogany brown. If the loaf is browning too quickly, lower the temperature by 25°F (15°C).

Step 14: Cool completely

Transfer the bread to a wire rack and allow it to cool for at least 1 to 2 hours before slicing. This helps the crumb finish setting and prevents a gummy texture. You may hear the crust crackle as it cools, which is a happy sign. 🍞

🔬 Understanding Each Stage of Sourdough

Sourdough is more about observing than following a strict timer. Here is what is happening at each stage, so you can make good decisions.

The autolyse (rest)

When flour and water sit together, enzymes begin breaking down starches and proteins, and the flour fully hydrates. This makes the dough more extensible and builds gluten with minimal effort.

Stretch and folds

Each fold aligns the gluten strands and builds strength. Gentle handling preserves the gas the yeast is producing, which leads to an open, airy crumb.

Bulk fermentation

This is the main rise, where the yeast and bacteria do most of their work. It is the most important step to get right, because it determines both the crumb structure and the flavor.

Signs that bulk fermentation is done:

  • The dough has grown by about 50 to 75 percent.
  • The surface looks domed and slightly jiggly when you shake the bowl.
  • You can see bubbles along the sides and a few on top.
  • The dough feels airy and light, and pulls away from the sides of the bowl.

Shaping and tension

Shaping creates a taut skin on the loaf’s surface, which holds the gas in and directs the rise upward during baking.

Cold fermentation (retarding)

Refrigerating the dough slows the yeast while the bacteria continue to produce acids and flavor compounds. This is why overnight sourdough is more flavorful. It also fits baking into your schedule, since you can bake whenever it suits you within the window.

Steam in the Dutch oven

The covered pot traps moisture released from the dough, creating a steamy environment that delays crust formation. This lets the loaf expand fully (oven spring) before the crust sets. Removing the lid later allows the crust to dry, brown, and crisp.

💡 Helpful Tips for Perfect Sourdough

  1. Use an active starter. Your starter should be bubbly and strong enough to rise predictably after feeding.
  2. Watch the dough, not just the clock. Fermentation time changes depending on room temperature and starter activity.
  3. Do not skip stretch and folds. They help strengthen the dough and create a better structure.
  4. Avoid overproofing. Dough that ferments too long may spread out and lose its ability to hold its shape.
  5. Keep your hands wet. Wet hands make sticky sourdough easier to handle.
  6. Use a hot Dutch oven. Trapped steam helps the loaf expand and develop a beautiful crust.
  7. Let it cool completely. Cutting into hot sourdough can make the inside gummy.
  8. Weigh your ingredients. A kitchen scale is the most reliable way to get consistent results with sourdough.
  9. Keep notes. Write down your timing, temperature, and results so you can adjust and improve with each bake.
  10. Be patient with yourself. Every loaf teaches you something, even the imperfect ones, which still make wonderful toast.

🔧 Troubleshooting: Common Sourdough Problems

My loaf is dense and heavy. The starter may not have been active enough, or the dough may have been under-fermented. Make sure the starter is bubbly and doubled, and give the dough enough time to grow 50 to 75 percent during bulk fermentation.

My loaf spread flat instead of rising up. This usually means the dough was over-proofed or did not have enough tension. Shorten the fermentation time, and focus on tightening the shape when you form the loaf. A weak starter can also be the cause.

The crumb has big, irregular tunnels with dense spots. Under-fermented dough often has large holes surrounded by gummy areas. Allow a little more bulk fermentation time next time.

The crust is too hard or too thick. It may have baked too long uncovered or at too high a temperature. Reduce the uncovered baking time slightly or lower the temperature by 25°F (15°C). Brushing the warm loaf with a little butter can soften the crust.

The crust is pale. Bake the loaf uncovered for a few more minutes until it reaches a deep golden brown. Make sure the Dutch oven was fully preheated and your oven is accurate.

The bottom is too dark or burned. Place a baking sheet on the rack beneath the Dutch oven to insulate the base, or move the pot up a rack. Using parchment helps as well.

The dough is too sticky to handle. Sourdough is naturally sticky. Wet your hands rather than adding extra flour, and use a bench scraper. Strength builds through stretch and folds, making the dough easier to manage over time.

The dough stuck to the basket. Use more flour, ideally rice flour, to coat the basket or towel generously. Make sure the dough is cold when you turn it out.

The loaf did not open at the score. The slash may not have been deep or confident enough, or the dough may have been over-proofed. Cut about ½ inch (1 cm) deep with a quick motion.

My bread is too sour (or not sour enough). Longer cold fermentation generally increases tang. For a milder flavor, shorten the cold ferment to 8 hours. For a more sour loaf, extend it up to 12 hours or a little longer.

The inside is gummy. The loaf was probably cut too soon, or was underbaked. Cool it for at least 1 to 2 hours, and bake until the crust is deeply golden.

My starter is not rising. It may be too cold, too young, or need more frequent feedings. Keep it somewhere warm, feed it regularly, and give it a few days of consistent feeding before baking.

🧊 Storage Instructions

Room temperature

Store the loaf in a paper bread bag or bread box for 2 to 3 days. Keep the cut side facing down on a cutting board to help preserve freshness. A cloth bag also works well. Avoid plastic bags if you want to keep the crust crisp.

Refrigerator

Not recommended. Refrigeration can make bread stale faster.

Freezer

Slice the completely cooled loaf and freeze in a sealed freezer bag for up to 3 months. Slices separate easily, so you can take out only what you need.

Reheating

Toast individual slices straight from the freezer, or warm larger portions in a 350°F (175°C) oven until refreshed. To revive a whole stale loaf, run it quickly under water, then bake at 350°F (175°C) for 8 to 10 minutes.

🥗 Nutrition Notes

Sourdough is made from just flour, water, and salt, with no added sugar or fat. Many people enjoy it because the long fermentation can make the bread easier to digest, though it still contains gluten, so it is not suitable for anyone who needs to avoid gluten.

Exact nutrition varies depending on ingredients and slice size. For accurate numbers, use a nutrition calculator with your specific ingredients.

❓ Frequently Asked Questions

Do I need a Dutch oven to bake sourdough?

A Dutch oven gives the best results because it traps steam and heat. If you do not have one, you can bake the loaf on a preheated baking stone or sheet, with a pan of hot water on the bottom rack for steam. The crust may be a little less crisp and the loaf slightly less tall.

How do I know if my starter is active enough?

It should be bubbly, have risen to about double its size after feeding, and smell pleasantly sour and yeasty. If it is flat and sluggish, feed it again and wait.

Can I use all-purpose flour instead of bread flour?

Yes, but the dough will be softer and slightly harder to handle, and the loaf may be a bit less tall and chewy. Bread flour gives the best structure.

Can I make this recipe without the cold fermentation?

You can shape the loaf and let it proof at room temperature for 1 to 2 hours instead, until puffy, then bake. The flavor will be milder, and the dough will be a little harder to score, but it works if you are short on time.

Can I bake the dough straight from the refrigerator?

Yes, and it is best that way. Cold dough holds its shape, is easier to score, and bakes up with better oven spring.

How long can I leave the dough in the refrigerator?

The recipe calls for 8 to 12 hours. Some bakers extend it to 16 hours or longer for more sour flavor, but the dough may become over-proofed, so check it and bake it when it feels puffy but not collapsed.

Why is my sourdough not sour?

Sourness develops with longer, cooler fermentation. For a tangier loaf, extend the cold fermentation or use a slightly more mature starter. Also, whole grain flours increase the tang.

What if I do not have a proofing basket?

Line a medium bowl with a clean kitchen towel and dust it generously with flour. The bowl supports the dough’s shape just like a basket would.

What if I do not have a bread lame?

A sharp razor blade, a very sharp knife, or even a pair of sharp kitchen scissors can score the loaf. Make a quick, confident cut about ½ inch (1 cm) deep.

Can I add the salt at the beginning?

You can, but adding it after the rest lets the flour hydrate first and makes the dough easier to work with. Adding it at the start works too, though the dough may be slightly less extensible.

How do I know when the sourdough is baked?

The crust should be deeply golden brown and crisp, and the loaf should sound hollow when tapped on the bottom. The internal temperature should reach about 205 to 210°F (96 to 99°C).

Why is my crumb tight and dense?

This often comes from under-fermentation, a weak starter, or not enough dough strength. Make sure the starter is active, the dough grows enough during bulk fermentation, and you complete all the stretch and folds.

Can I double this recipe?

Yes. Double the ingredients, divide the dough into two loaves at shaping, and bake them one at a time or in two Dutch ovens. The second loaf can stay in the refrigerator until the first is baked.

Can I use the discard instead of an active starter?

Unfed discard does not have enough strength to leaven this dough on its own. For this recipe, use an active, bubbly starter. Discard is better for pancakes, crackers, and other recipes that do not rely on it for the rise.

Is sourdough healthier than regular bread?

Sourdough has a few advantages, such as natural fermentation and good keeping quality, but it is still bread made from flour. Enjoy it as part of a balanced diet.

What is the difference between sourdough and regular yeast bread?

Sourdough relies on a natural culture of wild yeast and bacteria, which makes it rise slowly and develop tangy flavor. Regular yeast bread uses commercial yeast, which rises quickly and tastes milder.
