Few baking projects are as satisfying as pulling a deeply browned loaf of sourdough bread from the oven. The crisp crust crackles as it cools, the inside is soft and pleasantly chewy, and the flavor has a subtle tang that comes entirely from flour, water, salt, and a lively sourdough starter.
Sourdough can seem intimidating at first because the process depends less on rigid timing than most recipes. Your starter, room temperature, flour, and dough temperature all influence how quickly fermentation happens. Once you learn to watch the dough instead of only watching the clock, however, the process becomes much easier to understand.
This beginner-friendly recipe uses an active sourdough starter, bread flour, water, and salt. A few rounds of stretching and folding strengthen the dough, an overnight refrigerator proof develops flavor and makes the loaf easier to score, and a Dutch oven traps steam during the first part of baking to produce a crisp, beautifully browned crust.
🍞 Beginner Sourdough Bread Recipe
Prep time: About 30 minutes active time
Bulk fermentation: About 4–6 hours
Cold proof: 8–16 hours
Bake time: 45–50 minutes
Yield: 1 large loaf
Ingredients
- 100g active sourdough starter
- 350g water, lukewarm
- 500g bread flour
- 10g fine sea salt
- Rice flour or all-purpose flour, for dusting the proofing basket
For the most consistent results, use a kitchen scale. Sourdough doughs are especially sensitive to changes in flour and water, and measuring by weight removes much of the guesswork.
🫙 Start with an Active Sourdough Starter
The starter is the engine behind the entire loaf.
Use starter that has recently been fed and is clearly active. It should look bubbly, expanded, and lively rather than flat and inactive.
A mature starter commonly rises noticeably after feeding, although exactly how quickly this happens depends on its feeding ratio, temperature, flour, and overall strength.
Do not worry too much about catching one perfect minute when the starter is supposedly ready. What matters is that it is showing strong fermentation activity and has not been sitting neglected for days before you use it.
🌾 What If You Don’t Have a Starter Yet?
A sourdough starter is simply a culture of flour and water populated by naturally occurring yeast and bacteria.
Building one from scratch generally takes several days of repeated feeding. King Arthur Baking’s current starter method begins with equal weights of flour and water, then continues with regular feedings until the culture becomes reliably active.
The exact timeline varies. Some starters become dependable fairly quickly, while others need additional time before they reliably raise bread.
If your newly created starter produces a few bubbles on day two or three and then seems to become quieter, that does not necessarily mean anything has gone wrong. Continue feeding it consistently and give the microbial community time to stabilize.
🥣 Mix the Flour and Water
Place the bread flour and 350g water in a large mixing bowl.
Use your hands, a dough whisk, or a sturdy spoon to mix until no dry flour remains.
The dough will look shaggy and rough rather than smooth.
Cover the bowl and let it rest for about 30 minutes.
This flour-and-water rest is commonly called an autolyse. It gives the flour time to hydrate and begins developing dough structure before you start folding.
It is helpful, but it does not need to become another source of sourdough anxiety. Thirty minutes is plenty for this loaf.
🫧 Add the Starter and Salt
Add the 100g active sourdough starter to the dough.
With damp hands, pinch, squeeze, and fold the dough until the starter is well incorporated.
Sprinkle the salt over the surface and continue pinching and folding until the salt disappears into the dough.
The dough will feel sticky. That is normal.
Try not to respond by adding handfuls of additional flour. Extra flour changes the balance of the recipe and can lead to a much denser loaf.
Wet hands are usually much more effective than floured hands when working with sourdough.
⏰ Begin Bulk Fermentation
Once the starter and salt have been mixed in, bulk fermentation begins.
Cover the bowl and keep the dough at a comfortable room temperature.
A kitchen around 74–76°F (23–24°C) is a useful reference point, but you do not need to maintain exactly that temperature.
A warmer kitchen will make the dough ferment faster.
A cooler kitchen will slow it down.
This is why a recipe that says “ferment for exactly four hours” can work beautifully in one house and fail completely in another.
🤲 Stretch and Fold the Dough
During the first 90 minutes of bulk fermentation, perform 3 sets of stretch-and-folds about 30 minutes apart.
To complete one set, wet your hand and grab one side of the dough. Gently stretch it upward until you feel resistance, then fold it over the center.
Rotate the bowl about one-quarter turn and repeat.
Continue until all four sides have been stretched and folded.
Then cover the dough and let it rest until the next set.
Each round should make the dough feel a little smoother, stronger, and more elastic.
🧬 Why Stretch and Fold?
Sourdough does not need aggressive kneading to develop strength.
Stretching and folding gradually organizes and strengthens the gluten network while allowing the dough to ferment between each set.
At first the dough may spread loosely across the bowl.
After several folds, it should begin holding itself together more effectively and feel smoother when you lift it.
Once the third set is complete, leave the dough undisturbed for the remainder of bulk fermentation.
👀 Watch the Dough, Not Just the Clock
At a moderate room temperature, total bulk fermentation may take somewhere around 4 to 6 hours, but the dough itself is the better guide.
Look for a noticeable increase in volume, generally somewhere around 30 to 50 percent for a dough that will receive an overnight cold proof.
The dough should also look smoother and puffier than it did after mixing.
You may notice bubbles along the sides or surface, and the edges where the dough meets the bowl may appear slightly rounded or domed rather than flat.
When you gently move the bowl, the dough should have a light, slightly jiggly quality.
These signs matter more than whether the clock says exactly five hours.
🌡️ Temperature Changes Everything
Fermentation is highly temperature dependent.
If your kitchen is 68°F, the same dough may need considerably longer than it would at 78°F.
The strength and percentage of starter also matter.
This is one of the main reasons sourdough becomes easier with experience. You gradually learn what properly fermented dough looks and feels like in your own kitchen.
Writing down the room temperature and approximate fermentation time for each loaf can be surprisingly useful.
🚫 What Does Under-Fermented Dough Look Like?
Under-fermented dough tends to feel dense and tight rather than airy.
It may show very little increase in volume and few visible bubbles.
A baked loaf made from significantly under-fermented dough can have a dense crumb, poor rise, and areas that look slightly gummy.
Large tunnels surrounded by dense bread can also sometimes be a sign that fermentation was incomplete.
If your dough looks almost exactly as it did after mixing, it probably needs more time.
🎈 What About Over-Fermentation?
Over-fermented dough often becomes extremely loose and difficult to shape.
It may spread rapidly after being turned onto the counter and struggle to hold surface tension.
Once fermentation has gone too far, the gluten structure can have difficulty trapping all the gas being produced.
The finished loaf may spread outward rather than springing upward in the oven.
For a beginner, ending bulk fermentation slightly earlier is often easier to manage than pushing it too far.
🔪 Pre-Shape the Dough
Lightly flour your work surface and gently turn the fermented dough out of the bowl.
Using a bench scraper and your hands, bring the dough into a loose round.
Try to preserve as much of the trapped gas as possible rather than aggressively pressing everything out.
Let the dough rest uncovered for about 20 minutes.
This short bench rest allows the gluten to relax before final shaping.
If the round spreads slightly during the rest, that is normal.
🍞 Shape the Loaf
For a round boule, gently flatten the dough just enough to work with it.
Fold the edges inward toward the center, then turn the dough over so the seam is underneath.
Cup your hands around the dough and gently pull it toward you across the counter.
Rotate and repeat.
The friction between the dough and work surface tightens the outer surface and creates tension.
You want a smooth, taut exterior without tearing the dough.
🧺 Prepare a Proofing Basket
Dust a banneton generously with rice flour.
Rice flour is especially useful because it absorbs less moisture than wheat flour and helps prevent sticky dough from attaching itself to the basket.
If you do not own a banneton, use an ordinary bowl lined with a clean kitchen towel.
Dust the towel thoroughly with rice flour or a mixture of rice flour and bread flour.
Place the shaped loaf into the basket seam-side up.
Cover it so the surface does not dry out.
❄️ Cold Proof Overnight
Transfer the covered dough to the refrigerator for approximately 8 to 16 hours.
An overnight cold proof is convenient because it divides the bread-making process across two days.
It also develops additional flavor and firms the dough, which makes scoring and transferring it into the Dutch oven considerably easier.
Longer is not automatically better.
Fermentation continues in the refrigerator—especially during the first hours while the dough is cooling—so leaving every loaf cold-proofing for 36 or 48 hours can increase the risk of over-proofing.
For this recipe, overnight is a good starting point.
🗓️ An Easy Sourdough Schedule
You might feed your starter early in the morning and mix the dough once it becomes active.
Bulk fermentation then takes place during the afternoon.
Shape the loaf in the evening and refrigerate it overnight.
The following morning, preheat the oven and bake the loaf directly from the refrigerator.
Another option is beginning around lunchtime, shaping in the evening, and baking the following afternoon.
Sourdough can fit many schedules once you understand that fermentation time is flexible.
🔥 Preheat the Dutch Oven
The next day, place a lidded Dutch oven in the oven and preheat everything to 450°F (230°C).
Let the Dutch oven heat for about 40 to 45 minutes.
A thoroughly heated pot gives the cold dough an immediate burst of heat and traps the steam released from the dough itself.
That humid environment delays crust formation during the early part of baking, allowing the loaf to expand before the crust becomes firm.
⚠️ Be Careful with a Hot Dutch Oven
A cast-iron Dutch oven that has been preheated to 450°F is extremely hot.
Clear your workspace before taking it from the oven.
Use substantial dry oven mitts and have a heatproof surface ready.
Once the dough is in the pot, remember that the handles and lid remain dangerously hot even if they do not look different.
There is no need to add ice cubes or water to the Dutch oven. The covered loaf will create plenty of steam on its own.
✂️ Score the Dough
Remove the dough from the refrigerator only when the oven and Dutch oven are fully heated.
Turn the loaf onto a piece of parchment or a bread sling.
Using a bread lame, razor blade, or very sharp knife, make one confident slash across the surface approximately 1/4 to 1/2 inch deep.
Scoring gives the expanding dough a controlled place to open during baking.
Without a score, the loaf may still expand—but it will choose its own weak point and may burst unpredictably along the side or bottom.
🔥 Bake with the Lid On
Carefully lower the scored loaf into the hot Dutch oven.
Cover immediately and return the pot to the oven.
Bake covered for 25 minutes.
During this stage, steam trapped inside the Dutch oven keeps the surface of the dough flexible while the loaf expands.
That expansion is often called oven spring.
Try not to open the pot during this portion of baking.
🥖 Finish Baking Uncovered
After 25 minutes, carefully remove the lid.
Continue baking for another 20 to 25 minutes, or until the crust is deeply browned.
Do not be afraid of color.
A pale loaf often lacks the deeper roasted flavors and crisp crust that make naturally leavened bread so good.
The finished crust should look rich golden brown to mahogany in places rather than blonde.
An internal temperature around 205–210°F can be a useful additional check, although appearance and crust development matter too.
🧊 Cool the Bread Completely
Transfer the loaf to a wire rack.
Then comes one of the hardest parts of sourdough baking: do not slice it immediately.
The interior is still finishing its transformation as the loaf cools. Cutting into hot bread releases steam and can leave the crumb sticky or gummy.
Give the loaf at least 1 1/2 to 2 hours before slicing.
It may sound unnecessarily cruel after spending a day making bread, but the texture is worth the wait.
🔪 Why Is My Sourdough Gummy?
The first question is whether you cut the loaf while it was still hot.
Even perfectly baked bread can seem gummy when sliced too soon.
If the bread cooled completely and is still gummy, under-fermentation or underbaking may also be responsible.
A very dense crumb can hold moisture differently from a well-fermented loaf.
Try giving the dough more bulk-fermentation time and allowing the crust to become deeply browned during baking.
🏔️ Why Didn’t My Sourdough Rise?
Start with the starter.
If your starter was sluggish and barely expanded after feeding, it may not have had enough fermentation power to raise the loaf effectively.
Next, look at bulk fermentation.
If the dough went into shaping before it became noticeably airy and expanded, it may simply have needed more time.
Over-proofing can produce poor oven spring too, but for beginners, insufficient starter activity or under-fermentation are extremely common causes.
🥞 Why Did My Loaf Spread Flat?
Some spreading is normal when dough leaves the proofing basket.
If it immediately turns into a pancake, though, several things may be happening.
The dough could be over-fermented.
It might not have developed enough strength during mixing and folding.
The hydration may also be too ambitious for the flour you are using.
That is one reason this revised recipe uses 350g water rather than the wetter 375g formula. Once shaping feels comfortable, you can gradually experiment with adding more water.
💧 Does Higher Hydration Mean Better Bread?
Not necessarily.
Higher-hydration sourdough can produce a more open crumb, but it is also stickier and more difficult to handle.
An extremely open crumb is not automatically the sign of a superior loaf.
For sandwiches, toast, butter, and everyday eating, a moderately open crumb can actually be more practical because your toppings stay on the bread instead of falling through enormous holes.
Learn fermentation and shaping first.
You can always increase the water later.
🌾 Bread Flour vs. All-Purpose Flour
Bread flour generally contains more protein than all-purpose flour, which helps create the gluten strength needed to support a tall sourdough loaf.
That makes bread flour particularly useful when you are learning.
All-purpose flour can still produce excellent sourdough, but the dough may feel softer and may not tolerate the same amount of water.
If substituting all-purpose flour, consider holding back a small amount of water initially.
You can always add more.
🌾 Add Whole Wheat Flour
Once the basic loaf feels comfortable, replace 50 to 100g of the bread flour with whole wheat flour.
Whole wheat contributes additional flavor and gives the bread a slightly heartier character.
It also absorbs water differently, so you may notice the dough becomes somewhat firmer.
Whole grain flour can also encourage fermentation because it provides a wider range of nutrients for the organisms in the starter.
🌾 Try a Little Rye
Rye is another excellent sourdough addition.
Replacing about 25 to 50g of the bread flour with rye flour can add a subtle earthy flavor without dramatically changing the dough.
Larger percentages of rye behave very differently because rye does not develop gluten in the same way wheat does.
For a beginner loaf, a small amount is the easiest place to start.
🌻 Add Seeds
Sesame, sunflower, flax, pumpkin, and other seeds can turn a basic sourdough loaf into something entirely different.
Toast seeds first when appropriate for deeper flavor.
Seeds can be folded into the dough during one of the later stretch-and-fold sets.
Remember that some seeds absorb water, so large additions may slightly change the consistency of the dough.
You can also roll the shaped loaf in sesame seeds before proofing.
🌿 Rosemary Sourdough
Fresh rosemary works beautifully in sourdough.
Finely chop 1 to 2 tablespoons and gently fold it into the dough during the second or third folding session.
A little lemon zest can be added alongside it for a brighter loaf.
Rosemary sourdough is excellent with soups, roasted vegetables, chicken, or olive oil for dipping.
🧀 Cheese Sourdough
Once you’ve mastered plain bread, grated cheese can be folded into the dough.
Sharp cheddar, Parmesan, Gruyère, and aged Gouda are all good choices.
Add the cheese during the later stages of bulk fermentation rather than during the initial mix.
Keep the amount moderate so the dough still has enough structure to rise.
Cheese breads can brown more quickly, so watch the crust during the uncovered baking period.
🧄 Roasted Garlic Sourdough
Roasted garlic is much gentler than raw garlic and works especially well in bread.
Mash several roasted cloves and fold them gently into the dough along with herbs.
Avoid incorporating large amounts of wet additions because they can weaken the structure and create gummy spots.
A little goes a long way.
🫙 How Often Should You Feed a Starter?
That depends on where you keep it and how often you bake.
A starter maintained at room temperature needs frequent feeding because fermentation proceeds continuously.
King Arthur’s current smaller-starter method recommends feeding a room-temperature starter approximately every 12 hours.
A starter kept in the refrigerator needs much less attention and can be refreshed before you plan to bake.
If you bake only once a week or less, refrigerated storage is much easier than keeping a jar on the counter full time.
🧊 Refrigerating Your Starter
Once your starter is mature and established, refrigeration slows fermentation considerably.
That means you do not have to feed it every morning and evening indefinitely.
Before baking, take some starter out, feed it, and let it become active again at room temperature.
Depending on how long the starter has been refrigerated and how vigorous it is, it may need more than one feeding before it is ready to raise bread strongly.
Judge its activity rather than assuming one feeding will always be enough.
👃 What Should Sourdough Starter Smell Like?
A healthy starter can smell yeasty, fruity, tangy, mildly sour, or somewhat fermented.
The aroma changes depending on feeding schedule and maturity.
A sharp smell alone does not automatically mean the starter is bad.
Visible mold, unusual fuzzy growth, or pink or orange discoloration is much more concerning. A contaminated starter should be discarded rather than rescued.
🗑️ What Is Sourdough Discard?
When maintaining a starter, you remove part of it before feeding so the quantity does not grow endlessly.
That removed portion is called discard.
It may not be active enough to raise a loaf effectively on its own, but it still contains flour, water, acidity, and flavor.
Discard can be used in pancakes, waffles, crackers, muffins, pizza dough, and many other recipes instead of throwing it away.
🍕 Use Your Starter for Pizza
Once you have an active starter, bread is only the beginning.
Sourdough pizza dough uses the same basic fermentation principles but produces a completely different result.
The dough can be refrigerated for additional flavor, then stretched into pizza bases when you’re ready to bake.
Maintaining a starter feels considerably more worthwhile once it starts contributing to pizza night too.
🥪 How to Slice Sourdough Bread
Use a sharp serrated bread knife and let the loaf cool completely first.
For sandwiches, slightly thinner slices are easiest to work with.
For toast or serving alongside soup, cut them thicker.
Once you’ve cut into the loaf, place the cut side down against a cutting board for short-term storage. This protects the exposed crumb while allowing the crust to remain relatively crisp.
🧺 How to Store Homemade Sourdough
Fresh sourdough is best at room temperature rather than in the refrigerator.
Refrigerators accelerate bread staling even though they may seem like a logical storage place.
Once completely cool, store the loaf in a bread box, paper bag, clean kitchen towel, or other container that offers some protection without trapping excessive moisture.
Plastic keeps the crumb soft longer but also softens the crust.
Choose the storage method based on which texture matters more to you.
❄️ Freeze Sourdough for Longer Storage
Freezing is an excellent way to preserve bread.
Allow the loaf to cool completely and slice it before freezing.
Place the slices in a freezer-safe bag or airtight container.
You can then remove individual pieces whenever you need them and toast them directly from frozen.
This is particularly convenient if you bake large loaves but do not eat bread every day.
🔥 How to Refresh a Sourdough Loaf
A loaf that has lost some of its crispness can often be revived in the oven.
Lightly dampen the crust with water and warm the loaf in a moderate oven until the exterior becomes crisp again.
For individual slices, a toaster is even easier.
Day-old sourdough also makes excellent grilled cheese, French toast, croutons, bread pudding, and breadcrumbs.
Very little needs to go to waste.
📓 Keep a Sourdough Baking Journal
If you want more consistent bread, write down what happened.
Record the starter feeding time, room temperature, dough temperature if you measure it, bulk-fermentation duration, how much the dough rose, refrigerator time, and baking result.
Sourdough contains too many moving variables to remember accurately from one loaf to the next.
A few notes make it much easier to see patterns.
If one loaf was particularly good, you have a record of how you made it.
❤️ Sourdough Gets Easier with Every Loaf
The hardest part of sourdough is often not mixing the dough or shaping the bread.
It is learning when to stop waiting.
Recipes can give you useful windows, but fermentation ultimately happens on the dough’s schedule rather than yours.
An active starter, a few well-timed folds, enough bulk fermentation, gentle shaping, and an overnight refrigerator rest are all you really need for an excellent loaf.
Your first loaf may not have the dramatic open crumb you see in bakery photographs.
That does not make it a failure.
If it rises, tastes good, has a crisp crust, and makes excellent toast the next morning, you are already well on your way.
And the next loaf will teach you something else.
