Sourdough Ciabatta: The Holey Italian Loaf at Home

Ciabatta is famous for its wide, irregular holes and crackly crust. It's also famous for being intimidating because the dough is very wet. Once you stop fighting the hydration, it's actually one of the easier breads to bake.

The recipe

For two ciabattas:

Sourdough biga (built the night before)

• 100g bread flour
• 60g water (60% hydration)
• 10g sourdough starter
• Mix and rest 10–12 hours at cool room temperature

Final dough

• 400g bread flour
• 320g water (high hydration; the biga adds more)
• 170g biga (all of it)
• 10g salt
• 5g olive oil

Total dough hydration: about 80%.

Method

Mix

In a stand mixer with paddle (not hook): combine flour, water, biga, and salt. Mix on low for 4 minutes.

If mixing by hand: combine in a bowl with a wet hand. Mix until shaggy.

Develop gluten

Stand mixer: switch to dough hook, mix on medium for 4–5 minutes. Add olive oil and mix 1 minute more. Dough should clear the sides slightly.

By hand: do 4 sets of stretch and folds, 30 minutes apart.

Bulk ferment

3 hours at 75°F. Look for a 70% rise and many bubbles on the surface.

Divide and shape

Heavily flour your work surface. Pour out the dough — it will spread.

Cut into two equal rectangles with a bench knife. Don't try to shape them. Just transfer to a heavily floured tea towel or couche, supporting them on the towel.

Final proof

30–45 minutes on the towel. Don't worry if they look slack.

Bake

Preheat oven and stone or steel to 475°F for 45 minutes.

Transfer ciabattas (still on parchment if possible) directly to the stone. Steam aggressively for the first 15 minutes.

Bake 25–30 minutes until deeply golden and hollow-sounding when tapped.

Why ciabatta works

The biga gives flavor and dough strength. The high hydration gives an open crumb. The minimal handling lets the gas bubbles stay large.

Most "ciabatta failures" are over-handling. The dough wants to be wet and the bubbles want to stay big. Don't shape, don't degas, don't fold during bench rest.

Common mistakes

Tight crumb — over-handled, or not enough fermentation, or dough was too cold.

Tough crust — under-baked or insufficient steam.

Tortilla-flat shape — under-fermented or too low hydration.

Sticking to the towel — not enough flour on the towel. Use semolina or rice flour for less sticking.

Variations

• Rosemary ciabatta — knead 2 tbsp chopped fresh rosemary into the final dough
• Olive ciabatta — fold in 100g chopped olives at the second fold
• Whole wheat ciabatta — substitute 25% whole wheat flour, add 20g more water

What to serve with ciabatta

• Olive oil and balsamic for dipping
• Tomato bruschetta
• Italian sandwiches (panini)
• Soup (especially tomato or minestrone)
• Cheese boards

Storage

Ciabatta is best within 24 hours. After that, slice and freeze. Toast frozen slices for great results.

For longer fresh storage: leave it cut-side-down on a cutting board, loosely covered with a towel.

The lesson ciabatta teaches

Once you've made ciabatta successfully, you understand high-hydration dough. The same techniques apply to focaccia, pizza dough, and high-hydration country loaves.

Ciabatta is a good "first hard bread" for moving past basic country loaves. The wet dough is intimidating but fundamentally simple.

A test bake

Make ciabatta on a Saturday morning. By lunch you have fresh, holey, crackling Italian bread that you couldn't get this good from any local bakery.

That's the moment you realize home baking can match or beat retail bread.
