Ingredients You’ll Need

125g active sourdough starter (fed and bubbly)
375g filtered water (room temperature)
550g unbleached all-purpose flour
10g salt

That’s it, just four simple ingredients to make the perfect sourdough baguette. The magic comes from technique and time.

Step-by-Step Instructions

1. Mix the Dough

In a large bowl, combine the active sourdough starter, filtered water, and flour. Mix until no dry spots remain. Add salt and gently work it into the dough until incorporated.

2. Bulk Fermentation

Cover and let the dough rise at room temperature until it doubles in size, usually 4–6 hours depending on the warmth of your kitchen. You can perform stretch-and-folds every 30–45 minutes for the first couple of hours to strengthen the gluten structure.

3. Shape the Baguettes

Gently turn the dough onto a floured surface.
Divide the dough into 3 equal sections.
Shape each section into a rectangle.
Fold one long side over like a letter and press with your thumbs to seal.
Roll again carefully and seal with your thumbs, then pinch the seams tightly.
Place seam-side up on a floured tea towel on a baking sheet.

Shaping a sourdough baguette may take practice, but each time you’ll improve and achieve that classic long, slender loaf.

4. Cold Proof

Cover the baguettes and refrigerate for 12–14 hours. This slow fermentation develops the flavor, enhances the crust, and makes the dough easier to handle when baking.

5. Bake with Steam

Preheat oven to 475°F. Place a loaf pan with tea towels or lava rocks and carefully pour in boiling water to create steam.
Lower oven to 450°F and place baguettes on a floured baking sheet or pizza steel.
Bake for 15 minutes with steam, then remove the steam source.
Rotate the pan and bake another 15–20 minutes until golden brown and crisp.

6. Cool & Enjoy

Transfer the baked baguettes to a wire rack and allow them to cool completely before slicing. Cooling is essential! It sets the crumb and prevents the bread from becoming gummy inside.

Tips for the Best Sourdough Baguette

Use an active starter – A bubbly, doubled starter ensures proper rise and flavor.
Create steam – This step is non-negotiable if you want the iconic crisp crust.
Don’t rush proofing – Overnight fermentation builds both structure and flavor.
Score your loaves – Use a sharp blade or lame to score the baguettes before baking. This allows expansion and creates that signature rustic look.
Bake on steel or stone – For the crispiest crust, a pizza steel or baking stone is ideal.

How to Serve a Sourdough Baguette

A freshly baked sourdough baguette is so versatile that it pairs beautifully with almost anything. Here are some delicious ideas:

Simple & classic – Slice and spread with butter, jam, or soft cheese.
Sandwiches & paninis – The chewy crumb holds up to fillings without becoming soggy.
Soup companion – Perfect with French onion soup, tomato soup, or creamy chowders.
Charcuterie & cheese boards – Thin slices pair beautifully with meats, cheeses, and spreads.
Appetizers – Make crostini, bruschetta, or garlic bread.
Breakfast treat – Toasted with almond butter, honey, or avocado.

The options are endless, and a sourdough baguette is always a crowd-pleaser.

Troubleshooting Common Issues

Flat baguettes? The dough may have been over-proofed. Keep an eye on rise times.
Too dense inside? Starter might not have been active enough. Feed it regularly before baking.
Pale crust? Increase bake time slightly or ensure steam was properly added in the beginning.
Hard crust? Store your baguette wrapped in a clean kitchen towel instead of plastic to maintain crispness without it becoming too tough.

These adjustments will help you master the art of the sourdough baguette every time.
