Sourdough Baguette: French Crust, Homemade Sourdough

The baguette is the bread that humbled me. After months of successful boules and batards, I figured baguettes would be just a different shape. I was so wrong. My first attempt looked like a baseball bat. My second came out of the oven as a crescent moon. The third was passable, but the crust was chewy instead of crackly. It took me a solid dozen bakes before I produced something I’d be proud to set on a dinner table.

But here’s the good news: everything I learned the hard way, I can share with you. A sourdough baguette is genuinely one of the most rewarding breads you can bake at home. When that crust shatters under your fingers and you hear that symphony of crackling sounds, every frustrating attempt was worth it.

What Makes a Great Baguette

A proper baguette is defined by contrasts: a thin, shattering crust surrounding a creamy, open crumb. The flavor should be wheaty and sweet with a gentle sourdough tang — not aggressively sour. This means you want a young, mild levain rather than a mature, acidic one.

Full Recipe: Sourdough Baguettes (Makes 3)

Ingredients

• 500g bread flour (French T65 if you can find it, otherwise any strong white flour with 11-13% protein)
• 345g water (69% hydration, room temperature)
• 75g young sourdough starter (fed 4-5 hours ago, risen but not yet peaked)
• 10g salt

Notice the smaller amount of starter compared to most sourdough recipes. Baguettes benefit from a slower fermentation with less sourness. The lower starter percentage extends the ferment and develops more complex wheat flavors.

Method

Autolyse (1 hour): Mix flour and water until no dry flour remains. Cover and rest for 1 hour. This extended autolyse develops gluten passively and is especially important for baguettes because you want an extensible dough that stretches into long shapes without springing back.

Add starter and salt: Add the starter and salt together. Pinch and fold the dough in the bowl for 3-4 minutes until everything is incorporated. The dough should feel smooth and slightly tacky.

Stretch and folds (2 hours): Perform 4 sets of stretch and folds at 30-minute intervals. Each set should be gentle but thorough — stretch each side up and over the center. After the final fold, the dough should feel elastic and hold its shape when gathered into a ball.

Bulk fermentation (2-3 more hours): Leave the dough undisturbed after the last fold. You’re looking for a 60-70% volume increase. The dough should be puffy, with visible bubbles under the surface, and jiggle slightly when you tap the bowl. Understanding bulk fermentation timing is critical here — under-proofed baguettes have a tight crumb, while over-proofed ones collapse during shaping.

Divide and pre-shape: Turn the dough onto a lightly floured surface. Divide into 3 equal pieces (roughly 310g each). Gently shape each piece into a rough rectangle or short log. Don’t worry about perfection — this is just a pre-shape. Cover with a towel and rest 20-25 minutes.

Final shape: This is where baguette baking gets specific. For each piece:

1. Place the dough seam-side up. Gently flatten into a rectangle about 15cm wide.
2. Fold the top third down to the center and press the seam with your fingertips.
3. Fold the top edge down again to meet the bottom edge. Seal the seam firmly with the heel of your hand.
4. Roll the dough back and forth with both hands, working from the center outward, until it reaches about 35-40cm long. Apply gentle pressure — don’t squash the dough flat.

Our shaping fundamentals guide covers hand positioning and pressure in detail. For baguettes specifically, the key is working from the center out so you don’t get thin ends and a fat middle.

Final proof (45-60 minutes): Place the shaped baguettes seam-side up on a floured couche (linen cloth) or between the folds of a well-floured kitchen towel. The fabric supports the sides and prevents spreading. Proof at room temperature until puffy — a gentle poke should leave a slow-filling indent.

Preheat and prepare steam: Heat your oven to 250°C (480°F) with a baking stone or steel on the middle rack and a cast-iron pan or tray on the bottom rack. Boil a kettle of water. Steam is absolutely essential for baguette crust — without it, the surface sets too quickly and you get a thick, chewy crust instead of a thin, shattering one.

Score and bake: Gently roll the baguettes seam-side down onto a parchment-lined peel or flipped baking sheet. Score each baguette with 4-5 overlapping cuts at a 30-degree angle using a very sharp blade. The cuts should overlap by about a third — this creates the classic "ear" that opens during baking.

Slide the baguettes onto the stone and immediately pour a cup of boiling water into the cast-iron pan below. Close the oven quickly. Bake with steam for 10 minutes, then remove the steam tray (carefully — the steam is fierce), reduce the temperature to 230°C (450°F), and bake for 12-15 more minutes until deep golden brown with some charred spots on the scores.

Cool: Place on a wire rack. You’ll hear the crust crackling and singing as it cools — that’s the sound of success. Baguettes are best eaten within a few hours of baking, while the crust is still at its most shattery. Don’t refrigerate them — just leave them on the counter and enjoy them fresh.

Troubleshooting

The baguettes are too short and fat

Your bench rest wasn’t long enough, or you shaped too aggressively. Let the dough relax more, and use gentle rolling pressure from center to ends.

The crust is thick and chewy

Not enough steam. Make sure your oven is fully preheated, use plenty of boiling water, and close the door fast. Some bakers also mist the baguettes with a spray bottle right before closing the oven.

The crumb is tight with no open holes

Likely under-proofed during bulk, or the hydration was too low. Check your dough volume carefully during bulk fermentation, and consider bumping hydration to 71-72% on your next attempt.

Baguettes are the bread that teaches you precision. Every variable matters — shaping tension, proofing time, oven steam, scoring angle. But that’s also what makes them so rewarding. When you nail it, when you pull three golden, crackling baguettes from your home oven, you’ll feel like you’ve unlocked a new level of baking. And honestly, you have.
