Sourdough French Bread (Crispy Crust, Soft Chewy Center)

If you love the idea of homemade sourdough but want something a little different from a classic round boule, this Sourdough French Bread is for you. It has everything you love about naturally leavened bread — that deep, tangy flavor and beautifully open crumb — shaped into long, elegant French-style loaves instead. The result is a thin, golden, slightly crisp crust wrapped around a soft, chewy, airy interior.

This recipe uses just four ingredients: sourdough starter, bread flour, water, and salt. No commercial yeast, no shortcuts, just time, technique, and a little patience. The long, slender shape makes this loaf especially versatile, whether you’re building a sandwich, slicing it for garlic bread, or tearing off a warm piece to dip into soup. Below, you’ll find a full step-by-step guide, along with troubleshooting tips, serving ideas, and answers to common sourdough questions.

Why You’ll Love This Recipe

• Only four ingredients. Starter, flour, water, and salt — nothing else needed.
• Crispy, golden crust with a soft, chewy interior. The long, slender shape develops more crust per slice than a round boule.
• Naturally leavened. No commercial yeast required, just an active sourdough starter.
• Versatile shape. Perfect for sandwiches, garlic bread, and dipping into soups or sauces.
• Customizable. Once you’ve got the base loaf down, it’s easy to riff on with herbs, cheese, or seasonings.

Ingredients for Sourdough French Bread

• 100 g active sourdough starter
• 500 g bread flour
• 350 g filtered water, room temperature
• 10 g fine sea salt

Optional for Finishing

• A little flour, for dusting
• Melted butter, for brushing after baking, if you prefer a softer crust

Ingredient Notes

Sourdough starter. Your starter should be active and bubbly, ideally near its peak rise, when you use it. A sluggish or underfed starter will slow fermentation significantly and can result in a denser loaf. If you’re unsure whether your starter is ready, try the float test: drop a small spoonful into a glass of water — if it floats, it’s active enough to bake with.

Bread flour. Bread flour’s higher protein content compared to all-purpose flour helps this dough build the strong gluten network needed to hold its shape as a long, freestanding loaf rather than spreading out flat.

Filtered water. Using filtered or dechlorinated water can help support a more active fermentation, since heavily chlorinated tap water can sometimes slow down the beneficial bacteria and wild yeast in your starter. Room-temperature water is ideal for a steady, predictable ferment.

Fine sea salt. Salt does more than season the bread — it also strengthens the dough’s gluten structure and helps regulate fermentation speed, preventing the dough from over-fermenting too quickly.

This recipe is calculated at roughly 70% hydration (the ratio of water to flour), which is a fairly high hydration level well suited to an open, airy crumb, though it does make the dough feel a bit stickier to handle than a lower-hydration loaf.

Substitutions and Variations

• All-purpose flour: You can substitute all-purpose flour for bread flour, but expect a slightly less chewy texture and a loaf with a bit less structure, since all-purpose flour has less protein.
• Whole wheat blend: Substituting up to about 20% of the bread flour with whole wheat flour adds a heartier flavor, though you may need to increase the water slightly, since whole wheat flour absorbs more liquid.
• Flavor add-ins: Once you’re comfortable with the base recipe, you can fold in extras like shredded cheese, roasted garlic, fresh herbs, or everything bagel seasoning during shaping for a flavored variation.
• Softer crust: Brushing the loaves with melted butter right after baking will soften the crust if you prefer a less crackly exterior.

Kitchen Equipment

• Large mixing bowl
• Kitchen scale, for accurate weight-based measurements
• Bench scraper
• Parchment paper or a floured baker’s couche
• Baking stone, baking steel, or heavy baking sheet
• Bread lame or a very sharp razor blade
• Wire cooling rack

How to Make Sourdough French Bread

This recipe follows a classic no-knead sourdough method built around stretch-and-folds rather than traditional kneading, which develops strength in the dough gradually while preserving its airy structure.

Step 1: Mix the Dough

Add the active sourdough starter and water to a large mixing bowl, and stir until the starter is mostly dispersed throughout the water. Add the bread flour and mix until no dry flour remains. Cover the bowl and let the dough rest for approximately 30 to 45 minutes. This resting period, often called an autolyse, allows the flour to fully hydrate, which makes the dough easier to work with in the next step.

Sprinkle the salt over the rested dough and work it in thoroughly using damp hands. The dough may feel slightly sticky at first — that’s completely normal at this stage, especially given the dough’s fairly high hydration.

Step 2: Build Strength with Stretch-and-Folds

During the first two hours of bulk fermentation, perform 3 to 4 sets of stretch-and-folds, spaced about 30 minutes apart. For each set, gently grab one side of the dough, stretch it upward, and fold it over itself, then rotate the bowl and repeat around the dough. This technique builds gluten strength gently, without the aggressive kneading a lower-hydration dough would need. As the folds continue, you’ll notice the dough gradually becoming smoother, stronger, and more elastic.

Step 3: Bulk Fermentation

Cover the bowl and let the dough continue fermenting at room temperature. Rather than relying entirely on the clock, watch the dough itself. You’re looking for dough that has become noticeably puffier, developed visible bubbles at the surface and edges, increased substantially in volume, turned smoother and slightly domed on top, and feels light and airy when gently handled. Fermentation time will vary quite a bit depending on your kitchen’s temperature and how active your starter is, so be patient and let the dough’s appearance guide you.

Step 4: Divide the Dough

Turn the fermented dough gently onto a lightly floured work surface and divide it into 2 equal portions, using a bench scraper for clean cuts. Handle the dough carefully to avoid aggressively pressing out all the fermentation gases you worked to build. Gently pre-shape each portion into a loose rectangle or short log, then let the dough rest for approximately 15 to 20 minutes. This short rest, called a bench rest, relaxes the gluten and makes final shaping much easier.

Step 5: Shape the French Loaves

Working with one piece at a time, gently stretch the dough into a rectangle. Fold the upper third toward the center and press the seam gently, then fold the bottom portion upward and seal it. Carefully roll the dough into a long loaf, approximately 12 to 14 inches long, then repeat with the second piece. The goal throughout shaping is to build enough surface tension for the loaves to hold their long, slender shape in the oven, without squeezing out all the air you’ve developed inside.

Step 6: Final Proof

Place both shaped loaves seam-side down on parchment paper or a lightly floured baker’s couche. Cover them loosely and let them proof until they look noticeably puffier and feel light to the touch. If you’d like to develop deeper sourdough flavor, you can refrigerate the shaped loaves for a longer cold proof instead of proofing them at room temperature — just plan for a longer overall timeline.

Step 7: Score the Loaves

Preheat the oven to 450°F (230°C), and place a baking stone, baking steel, or heavy baking sheet inside while the oven heats, giving it plenty of time to get fully hot. Just before baking, dust the loaves lightly with flour if you’d like. Using a bread lame or a very sharp razor, make 3 to 4 diagonal slashes across each loaf, allowing the cuts to slightly overlap along the length of the bread. Scoring controls exactly where the dough expands in the oven, giving you those classic French-loaf slashes as the bread rises.

Step 8: Bake

Carefully transfer the loaves to the hot baking surface. Add steam at the beginning of baking using your preferred method — such as a pan of hot water on a lower oven rack, spritzing the oven walls with water, or covering the loaves briefly with an inverted pan. Steam helps keep the crust flexible during the initial oven spring, before it sets into that beautiful crisp exterior. Bake for approximately 20 to 25 minutes, until the loaves develop a deep golden-brown crust. For a darker, crispier crust, let them bake a few minutes longer. Transfer the finished loaves to a wire cooling rack.

Step 9: Cool Before Slicing

This is the hardest part: try not to slice into the bread right away. Let it cool fully so the crumb has time to finish setting. Once cooled, slice through the crisp golden crust to reveal the soft, chewy sourdough crumb underneath.

What Makes Sourdough French Bread Different?

Traditional artisan sourdough is usually shaped into a large round boule or oval bâtard. This recipe uses the same basic sourdough principles and ingredients but transforms the dough into two long, French-style loaves instead. That shape gives you a higher crust-to-crumb ratio for extra crispness, a soft and chewy center, beautifully elongated slices, and a shape that’s especially well suited to sandwiches, garlic bread, and dipping into soups or sauces.

Expert Tips for the Best Results

• Judge fermentation by appearance, not just time. Kitchen temperature and starter strength both vary, so use the visual and textural cues in the recipe — puffiness, bubbles, volume, and a light, airy feel — as your main guide.
• Build surface tension during shaping. Good tension helps the loaves rise upward and hold their long shape in the oven, rather than spreading outward.
• Handle fermented dough gently. Preserving some of the air you built during bulk fermentation and the stretch-and-folds is key to an open, airy crumb.
• Don’t skip the steam. Steam during the first part of baking keeps the crust flexible long enough for full oven spring before it crisps up.
• Let the bread cool completely. As tempting as it is to cut into a warm loaf, doing so before it’s finished cooling can leave the crumb gummy.

Common Mistakes to Avoid

Over-fermenting the dough. If the dough becomes extremely loose, slack, or fragile, it becomes much harder to shape into long loaves that hold their form. Keep an eye on the dough and move to shaping once it shows the signs described above, rather than letting it ferment indefinitely.

Skipping the stretch-and-folds. Because this is a no-knead style dough, the stretch-and-fold sets are what build the gluten strength needed for a good rise and open crumb. Skipping them can lead to a flatter, denser loaf.

Pressing out too much air during shaping. Handling the dough too roughly when dividing and shaping can deflate the air pockets you worked to build, resulting in a denser crumb.

Skipping steam at the start of baking. Without steam, the crust can set too early, restricting oven spring and leading to a shorter, denser loaf with a less impressive crust.

Slicing too soon. Cutting into the bread before it’s fully cooled can leave the interior gummy, even if the loaf is completely baked through.

Ways to Serve It

• Slice it and serve warm with salted butter.
• Turn it into sourdough garlic bread with butter, garlic, Parmesan, and parsley.
• Use longer slices for hearty sandwiches.
• Toast slices and top with tomatoes, mozzarella, or avocado.
• Tear off a warm piece and dip it into olive oil, soup, or pasta sauce.

Easy Variations

Once you’ve mastered the basic loaf, you can build on the same dough and technique to create:

• Garlic Parmesan Sourdough French Bread
• Rosemary & Sea Salt Sourdough French Bread
• Cheddar Jalapeño Sourdough French Bread
• Everything Bagel Sourdough French Bread
• Italian Herb & Parmesan Sourdough French Bread
• Cheesy Sourdough Garlic Bread

For most of these, fold the mix-ins gently into the dough during shaping, or sprinkle toppings onto the loaves right after scoring, before they go into the oven.

Make-Ahead Instructions

This recipe is naturally suited to a make-ahead schedule. After shaping, you can refrigerate the loaves for a long, cold final proof instead of proofing them at room temperature. This slows fermentation down, develops a more pronounced sourdough tang, and lets you bake fresh bread on your own schedule — simply bring the loaves closer to room temperature before baking, or bake straight from the fridge with a slightly longer bake time.

Storage Instructions

Room Temperature

Store the cooled loaves in a paper bag or bread bag at room temperature for up to 2 to 3 days. Avoid airtight plastic bags if you want to preserve the crisp crust, since trapped moisture will soften it.

Freezing

To freeze, wrap the fully cooled loaves tightly in plastic wrap and then foil, or place them in a freezer bag, and freeze for up to 3 months. Slicing before freezing makes it easy to pull out individual pieces as needed.

Reheating

To refresh a whole loaf, warm it in a 350°F (175°C) oven for about 10 minutes to re-crisp the crust. Frozen slices can go straight into a toaster, or a frozen whole loaf can be thawed at room temperature and then reheated in the oven.

Frequently Asked Questions

Can I make this bread without stretch-and-folds? Stretch-and-folds are important for building the gluten strength this dough needs, since it isn’t kneaded. You can technically knead the dough by hand instead, but the stretch-and-fold method is generally easier to manage with such a high-hydration dough.

Why is my dough so sticky? This dough is intentionally high-hydration, which makes it feel sticky, especially early on. Damp hands during mixing and shaping, along with a properly floured work surface, will make it much more manageable.

Can I bake this without a baking stone or steel? Yes. A heavy baking sheet works as a substitute, though a baking stone or steel does help produce a crisper bottom crust by holding and transferring heat more evenly.

Why didn’t my loaves rise as much as expected? This is usually related to an underactive starter, insufficient fermentation time, or over-handling the dough during shaping, which can knock out too much air. Make sure your starter is active and near its peak before starting.

Can I do a cold proof in the refrigerator? Yes. Refrigerating the shaped loaves for a longer cold proof is a great way to develop more sourdough flavor and can also fit better into your schedule, since you can bake the next day.

How do I know the bread is fully baked? The crust should be deeply golden brown, and the loaf should sound hollow when tapped on the bottom. If you’d like a more precise check, an instant-read thermometer inserted into the center should read approximately 205°F to 210°F.

Why is my crumb dense instead of open and airy? A dense crumb is often caused by an inactive starter, insufficient bulk fermentation, or handling the dough too roughly during shaping. Focus on the visual fermentation cues in the recipe, and try to handle the dough as gently as possible once it’s fully fermented.
