Classic Sourdough Bread Recipe

If you’ve ever watched a bakery loaf crackle while cooling and thought, “Yes, I want my kitchen to do that,” welcome.
A classic sourdough loaf is equal parts science experiment, edible aromatherapy, and the most satisfying way to turn flour into bragging rights.
The good news: you don’t need a degree in yeast psychology. You just need a healthy starter, a little patience, and the willingness to let time do most of the work.

This guide is a practical, classic sourdough bread recipe designed for home ovensthink: crusty artisan sourdough, open (but not “Swiss-cheese chaos”) crumb,
and that signature tang from natural fermentation. It’s also built for real life: you’ll get a clear timeline, temperature targets, and troubleshooting so you can
fix the loaf before you name it and get emotionally attached.

What Makes Sourdough “Classic”?

Classic sourdough bread is leavened by a sourdough starter (wild yeast + lactic acid bacteria), not commercial yeast.
That fermentation creates complex flavor, better keeping quality, and a crust that sings little crunchy songs when it cools.
The “classic” method usually includes:

• High-ish hydration dough for a lighter crumb
• Autolyse (a short flour-and-water rest) to improve gluten development and extensibility
• Stretch-and-folds during bulk fermentation to build strength without kneading forever
• Cold proof in the fridge for better flavor, easier scoring, and a more dramatic oven spring
• Hot Dutch oven (or similar covered vessel) to trap steam and maximize crust and rise

Ingredients (With Baker’s Logic)

This is a one-loaf, “country-style” sourdough formula that’s friendly to most starters. It’s written in grams because sourdough is happiest when you measure like a grown-up.
(Also because flour can’t decide how fluffy it wants to be in a measuring cup.)

Classic Sourdough Dough Formula (1 Loaf)

• Bread flour: 500 g (plus extra for dusting)
• Water: 350 g (room temp, adjust as needed)
• Active sourdough starter (100% hydration): 100 g
• Fine sea salt: 10 g

What Those Numbers Mean (Quick Analysis)

With a 100% hydration starter, that 100 g starter contains about 50 g flour + 50 g water. So your total flour is ~550 g, total water ~400 g, and overall hydration is ~73%.
That’s high enough for an airy artisan crumb, but not so wet that you’ll need a therapy session after shaping.

Equipment You’ll Actually Use

• Digital kitchen scale (sourdough’s best friend)
• Mixing bowl (big enough for the dough to grow without escaping)
• Dough scraper (bench scraper is ideal)
• Proofing basket (banneton) or a bowl lined with a floured towel
• Dutch oven (4–6 quart) or covered bread baker
• Lame or sharp blade for scoring
• Parchment paper (optional but very helpful for safe transfers)
• Instant-read thermometer (optional, but it ends “is it done?” arguments)

Before You Start: Make Sure Your Starter Is Ready

A classic sourdough bread recipe lives or dies by starter strength. Ideally, feed your starter 4–12 hours before mixing (depending on temperature and feeding ratio),
and use it when it’s active, bubbly, and near peak.

• Ready-to-use signs: doubled (or close), lots of bubbles, domed top (or just starting to flatten), smells pleasantly tangy
• Not ready: flat, sleepy, smells harsh like nail polish remover (it’s hungry), or hasn’t risen much after feeding

If your kitchen runs cold, your starter will run slow. If it’s warm, everything moves faster. Sourdough is basically weather with feelings.

Classic Sourdough Bread Recipe: Step-by-Step

Suggested Timeline (So This Fits Your Life)

Here’s a common schedule. Adjust based on dough temperature and how fast your starter ferments.

1) Autolyse (Optional, But Worth It)

In a large bowl, mix 500 g bread flour with 325 g of the water (reserve 25 g for later). Stir until no dry flour remains.
Cover and rest for 30–60 minutes.

Why autolyse works: flour fully hydrates, gluten begins forming naturally, and the dough becomes easier to handle.
It’s like letting your ingredients stretch before the workout.

2) Mix in Starter and Salt

Add 100 g active starter to the dough. Pinch, fold, and squish it in until mostly incorporated.
Sprinkle on 10 g salt, then add the remaining 25 g water and mix until the dough feels more cohesive.

Mixing tip: if the dough feels slippery or breaks apart, keep folding and pinching. It will come together. Sourdough loves drama, but it usually resolves by act two.

3) Bulk Fermentation (With Stretch-and-Folds)

Cover the bowl and let the dough ferment at room temperature for 3–5 hours (longer if your kitchen is cool).
During the first 2 hours, do 3–4 sets of stretch-and-folds every 30 minutes.

How to Stretch-and-Fold

1. Wet your hand slightly to prevent sticking.
2. Grab one side of the dough, stretch it up gently, and fold it over the center.
3. Rotate the bowl and repeat 3–4 times (north/south/east/west).
4. Cover and rest until the next set.

How to Know Bulk Fermentation Is Done

Don’t rely only on a clock. Look for a combination of signals:

• Volume increase: about 30–70% (more rise in white flour doughs, less in whole-grain-heavy doughs)
• Texture: dough feels lighter and a little puffy, not dense
• Surface: bubbles at the edges and/or top
• Wobble test: when you jiggle the bowl, the dough trembles like a comfy mattress

4) Pre-Shape and Bench Rest

Lightly flour your counter. Turn out the dough and gently form it into a round.
Don’t deflate it like you’re mad at itbe firm but kind. Let it rest uncovered for 20–30 minutes.

This rest relaxes gluten, making final shaping easier and improving oven spring.

5) Final Shape (Build Surface Tension)

Shape into a boule (round) or batard (oval). The key is surface tensiona taut outer “skin” that helps the loaf rise upward instead of spreading outward.

For a boule: flip the dough seam-side up, fold edges toward the center, then flip seam-side down and gently drag it toward you to tighten the surface.

6) Cold Proof (Overnight for Flavor and Control)

Place the shaped dough seam-side up in a well-floured banneton (or towel-lined bowl). Cover and refrigerate for 8–18 hours.

Cold proofing slows fermentation, deepens flavor, and makes scoring easier because the dough is firmer.
Also: it lets you bake bread in the morning and feel like you have your life together.

7) Bake in a Dutch Oven (Steam Without Fancy Equipment)

Place your Dutch oven (with lid) in the oven and preheat to 500°F for at least 30–45 minutes.

1. Cut a piece of parchment paper large enough to lift the dough.
2. Remove dough from fridge. Flip it onto parchment (now seam-side down).
3. Score the top with one confident slash (about 1/4–1/2 inch deep). Confidence matters. Dough can smell fear.
4. Carefully place the dough (on parchment) into the hot Dutch oven. Cover with the lid.
5. Bake 20 minutes covered at 500°F.
6. Reduce heat to 450°F, remove lid, and bake 20–25 minutes uncovered until deeply browned.

Optional doneness check: internal temperature should be about 205–210°F.
The crust should be bold brown, and the loaf should sound hollow when tapped (like it’s knocking back).

8) Cool (Yes, You Have to Wait)

Move the loaf to a rack and cool for at least 1 hour before slicing.
Cutting too early can trap steam and make the crumb gummy. Let the bread finish baking itself on the inside.

Troubleshooting (Because Sourdough Is a Diva)

My loaf is dense and tight. What happened?

• Starter wasn’t strong enough: feed it and use at peak.
• Under-fermented dough: extend bulk fermentation; look for puffiness and bubbles.
• Too much flour during shaping: a little flour is fine; a snowstorm can prevent proper sealing and structure.

My dough spread out like a pancake.

• Over-proofed: shorten bulk or cold proof next time.
• Not enough dough strength: add one more set of folds or tighten shaping.
• Hydration too high for your flour: reduce water by 15–25 g next bake.

My loaf is sour… like, aggressively sour.

• Longer fermentation = more sourness: shorten cold proof or bulk time.
• Warmer temps speed acid production: ferment cooler if possible.
• Starter balance: a very acidic starter can be refreshed with a couple of regular feedings before baking.

My crust is too dark (or the bottom burns).

• Lower the rack position or place a baking sheet on a lower rack as a heat shield.
• Reduce uncovered bake time slightly, or drop temperature by 25°F.
• Try parchment plus a light dusting of rice flour in the banneton to reduce sticking without extra scorching flour.

Flavor, Flour, and “Make It Yours” Options

A classic sourdough loaf doesn’t need upgradesbut it welcomes them.

• More flavor: swap 50–100 g of bread flour for whole wheat or rye (expect slightly less rise and a tighter crumb).
• More open crumb: keep handling gentle, nail fermentation, and avoid over-flouring during shaping.
• More crust: bake a little longer uncovered or crack the oven door for the last 5 minutes.
• More convenience: mix in the evening, bulk overnight at cool room temp (only if your starter and temps support it), bake in the morning.

How to Store Sourdough (So It Stays Amazing)

• Day 1: keep cut-side down on a cutting board, or wrap loosely in paper.
• Days 2–3: store in a bread bag or paper bag inside a plastic bag (balanced humidity helps).
• Longer storage: slice and freeze. Toast straight from frozen for peak “fresh bread” vibes.

Conclusion

A classic sourdough bread recipe is less about perfect timing and more about learning what the dough is telling you.
When your starter is lively, your bulk fermentation is properly developed, and your bake is steamy and hot, you’ll get that
crackly crust, balanced tang, and springy crumb that makes sourdough the undisputed champion of “I made this” foods.

And remember: every loaf teaches you something. Even the weird ones. Especially the weird ones.

of Real-World Sourdough Experiences (The Stuff Recipes Don’t Always Say Out Loud)

Here’s a truth that seasoned bakers love and beginners hate: sourdough is not a single recipeit’s a relationship with your kitchen.
Two people can follow the same “classic sourdough bread recipe” and end up with totally different loaves, because the variables are
sneaky. Room temperature, flour brand, starter strength, and even how warm your hands are can nudge fermentation forward or slow it down.
That’s why so many home bakers eventually stop asking, “How many hours?” and start asking, “How does the dough feel?”

One of the most common early experiences is the Overnight Optimism Trap: you set the dough to bulk ferment,
go to bed imagining a proud, billowy mass in the morning, and wake up to something that looks… exactly the same.
This usually happens in cool kitchens, where fermentation moves like it’s stuck behind a school bus. The fix isn’t panicit’s warmth
(a slightly warmer spot), time, and a starter that’s truly active. Many bakers discover that their “starter is bubbly” but not actually
strong enough to lift bread dough reliably, and a couple of consistent feedings changes everything.

Then there’s the opposite experience: the Runaway Dough Situation. The dough rises quickly, feels gassy,
and looks ready… and then, after shaping, it deflates or spreads. That’s often a sign it fermented a bit too far during bulk,
or didn’t build enough strength. The “aha” moment for many bakers is realizing that more rise isn’t always better.
Bulk fermentation isn’t a race to double; it’s a controlled development of structure and gas retention.

A classic sourdough milestone is the first time you nail the score. Early on, people tend to baby the blade:
shallow, hesitant cuts that seal up instantly in the oven. Then you finally make one clean, confident slash and the loaf blooms
dramatically. It feels like the bread is applauding you. (It’s not. But it could be.)

Another shared experience: learning when to stop adding flour. In the beginning, sticky dough is scary, so flour becomes a security blanket.
Too much flour during shaping can prevent the dough from sealing properly and reduce oven spring. Many bakers find that slightly wet hands,
a dough scraper, and a light dusting of flourrather than a blizzardmake shaping cleaner and results better.

Finally, there’s the universally humbling moment: slicing too soon. It smells incredible. You’re proud. You cut into it and the crumb is
gummy because it needed another hour to cool. Nearly every sourdough baker does this once. Consider it an initiation ritual.
The good news is: even imperfect sourdough makes fantastic toast. And the next loaf gets betterbecause you do.
