High-Hydration Artisan Sourdough Focaccia
Shatteringly crisp golden crust with pillowy, olive-oil-drenched crumb
Artisan Sourdough Focaccia Baker's Formula & Timing At A Glance
Artisan sourdough focaccia is crafted at 82% apparent hydration (reaching 84.5% true total hydration), with 85% high-protein bread flour, 15% whole wheat or semolina, 20% active sourdough starter, 2.2% fine sea salt, and 5% extra virgin olive oil in the dough mix. Proved for 4 hours at room temperature followed by an optional overnight cold retard or 3-hour warm pan proof until billowing with gas, then dimpled with wet-oiled fingers and baked at 425°F–450°F (220°C–232°C) in an oiled pan for 25–30 minutes.
Dough Rheology & Handling Dynamics
Physics of gluten hydration, elasticity, and tackinessWith 84.5% total water and 5% olive oil, the dough matrix acts as a semi-viscous fluid foam. Gluten is developed through time and coil folds in a glass dish rather than intensive kneading. The oil coats gluten proteins, creating a melt-in-the-mouth, tender crumb that resists staling.

Step-by-Step Artisan Method
Carefully curated instructions designed for consistency, oven spring, and blistering.
Levain Build
Phase: Levain BuildFeed starter at 1:1:1 or 1:2:2 ratio with warm water (80°F / 27°C). Allow to rise until doubled or tripled in size with a bubbly dome.
Autolyse & Hydration
Phase: AutolyseMix bread flour, semolina flour, and 92% of the formula water in a bowl. Rest 45 minutes.
Incorporate Starter, Salt, Bassinage & Oil
Phase: MixingAdd the active levain, 2.2% sea salt, reserved bassinage water, and 5% extra virgin olive oil. Squeeze and fold until the oil is completely emulsified into the dough.
Coil Folds & Tension Building
Phase: Coil FoldsPerform 3 sets of coil folds in the bowl at 40-minute intervals using wet hands. Lift the center until ends tuck underneath.
Pan Transfer & Overnight Cold Proof
Phase: Pan ProofingPour 30g of olive oil into a 9x13 or half-sheet baking pan. Gently tip dough into the center. Do not force it to the corners. Cover and chill in the refrigerator for 8–18 hours (or room temp proof for 3–4 hours).
Final Warm Proof, Dimpling & Brine
Phase: Dimpling & ToppingBring pan to room temperature (75°F–80°F) for 2–3 hours until puffy and jiggly. Drizzle with 15g olive oil and warm brine water. Press fingertips firmly down to the pan bottom to dimple. Scatter fresh rosemary and flaky sea salt.
High-Heat Crisp Bake
Phase: BakeBake on the lowest oven rack at 450°F (232°C) for 25–30 minutes until the top is deeply golden brown and the bottom crust sizzles and lifts easily from the pan.
Artisan Baker's Golden Rules for this Recipe
Dark Metal Sheet Pan: Use an anodized aluminum or blue steel baking pan (like LloydPans 9x13 or half-sheet). Light shiny pans reflect heat and result in soggy, pale bottoms.
The Olive Oil Pool: Do not skimp on the pan oil. Focaccia is fundamentally fried on the bottom surface during baking, creating that legendary glass-crisp exterior.
Brine Water Emulsion (Salmoia): Whisk 2 tbsp warm water with 1 tbsp olive oil and pour over the dough before dimpling. The water prevents the surface from drying out while deep craters form.
Fingertip Dimpling Technique: Spread your fingers wide and press straight down until your pads touch the cold metal bottom of the pan. Never pinch or tear bubbles.
Frequently Asked Questions & Troubleshooting
Q:How do I keep my high-hydration focaccia from sticking to the baking pan?
Two golden rules: 1) Use a well-seasoned nonstick pan, anodized aluminum, or blue steel pan, or line standard pans with parchment paper under the olive oil; 2) Ensure you pour at least 30–40g of olive oil into the pan. The dough literally fries in the oil, making sticking impossible.
Q:Why do you use a brine emulsion (water + oil) before dimpling?
In traditional Ligurian focaccia (Focaccia Genovese), the brine creates pockets of silky, custard-like texture in the dimple valleys while the ridges bake into crisp, crackly peaks. Pure oil alone often evaporates or burns fresh herb leaves.
Q:Can I make this focaccia same-day without the overnight cold retard?
Yes! After transferring dough to the oiled pan, let it proof in a warm spot (78°F–82°F) for 3.5 to 4.5 hours until it fills the pan, bubbles vigorously, and wobbles like Jell-O when gently nudged. Dimple and bake immediately.
Q:What flour is best for sourdough focaccia?
High-protein unbleached bread flour (12.7%–14% protein) is essential to hold the 84.5% True Total Hydration. Adding 15% semolina rimacinata (durum wheat) provides an irresistible golden color and nutty flavor profile.
