What Ingredients You Will Need

This crispy overnight sourdough focaccia with rosemary and sea salt relies on straightforward, wholesome ingredients that come together beautifully to create layers of flavor and texture. The magic happens with just a few pantry staples and a little patience.

• Active sourdough starter (about 100g/3.5 oz) – This is your natural yeast, providing that characteristic tang and lift. I prefer a bubbly, well-fed starter like King Arthur’s for consistent results.
• All-purpose flour (350g/12.3 oz) – You can swap half for bread flour if you want an extra chew, but all-purpose works just fine.
• Warm water (280ml/9.5 fl oz) – Lukewarm, around 75°F (24°C), to help activate the starter without shocking it.
• Extra virgin olive oil (50ml/3.3 tbsp) – Half goes into the dough, half for drizzling. Use a good quality brand like California Olive Ranch for true depth of flavor.
• Fine sea salt (10g/2 tsp) – Mixed in the dough for seasoning.
• Fresh rosemary (1–2 tbsp, chopped) – Adds that piney herb aroma and taste that pairs perfectly with the sourdough.
• Coarse flaky sea salt (for sprinkling) – This is the final touch, giving bursts of salty crunch on the crust.

Optional additions could be a sprinkle of crushed red pepper flakes for a little heat or some thinly sliced garlic tucked into the dimples if you’re feeling adventurous. But honestly, simplicity is the beauty here — the star is the crispy sourdough focaccia itself.

Equipment Needed

• Large mixing bowl: For combining and resting the dough. A glass or ceramic bowl works well to hold warmth.
• Kitchen scale: I can’t stress this enough; measuring by weight ensures consistent results every time.
• 9×13-inch (23×33 cm) baking pan or sheet pan: The size is perfect for this focaccia’s shape and thickness.
• Plastic wrap or clean kitchen towel: To cover the dough during its overnight rise, trapping moisture without suffocating.
• Pastry brush: Handy for drizzling olive oil evenly over the dough before baking.
• Cooling rack: For letting the focaccia rest after baking to keep that crust crisp.

If you don’t have a kitchen scale, measuring cups can work, but the texture might vary—trust me, weighing flour makes a world of difference in bread baking. Also, I once tried this in a cast iron skillet instead of a baking pan, and it gave a slightly different crust texture, which was a nice twist. Just make sure your pan isn’t too small, or the bread will be too thick and undercooked inside.

Preparation Method

1. Mix the dough (10 minutes): In your large bowl, combine 100g (3.5 oz) active sourdough starter with 280ml (9.5 fl oz) warm water. Stir to dissolve the starter. Add 350g (12.3 oz) all-purpose flour and 10g (2 tsp) fine sea salt. Mix with a wooden spoon or your hands until a shaggy dough forms. Add 25ml (1.5 tbsp) olive oil and mix it in until just combined. The dough will be sticky and loose—that’s exactly right.
2. First rest (30 minutes): Cover the bowl loosely with plastic wrap or a towel. Let the dough rest at room temperature (around 70°F/21°C) for 30 minutes. This allows hydration and gluten development to begin.
3. Stretch and fold (5 minutes): Wet your hands to prevent sticking. Reach under the dough, gently stretch one side, and fold it over the center. Rotate the bowl and repeat 3 more times, folding each side in. This helps develop dough strength without kneading.
4. Overnight rise (8-12 hours): Cover again and leave the dough to ferment overnight on the counter or in a slightly cool spot. The dough will double in size and become bubbly.
5. Prepare the pan: Next morning, generously oil your 9×13-inch pan with olive oil (about 15ml/1 tbsp). Gently transfer the dough into the pan, trying not to deflate it too much. Use your oiled fingers to press and stretch the dough evenly to the edges. Don’t worry if it resists a bit; patience wins here.
6. Dimple the dough and add toppings (5 minutes): Using your fingertips, press deep dimples into the dough all over. Drizzle the remaining 25ml (1.5 tbsp) olive oil over the surface, sprinkle chopped fresh rosemary and a generous pinch of coarse flaky sea salt.
7. Final proof (45 minutes): Let the dough rest and rise again in the pan for about 45 minutes. It should puff up slightly.
8. Bake (25-30 minutes): Preheat your oven to 450°F (230°C). Place the pan on the middle rack and bake until the focaccia is golden brown and crispy, about 25-30 minutes. The edges should feel firm, and the surface crackly. If your oven runs hot, check around 20 minutes to avoid burning.
9. Cool and enjoy: Remove the focaccia from the pan and cool on a rack for at least 15 minutes before slicing. This resting helps the crust stay crisp and the crumb set properly.

Pro tip: If the dough seems too sticky to handle after overnight fermentation, wet your hands well before pressing it into the pan—it makes a huge difference. And remember, don’t skimp on the olive oil; it’s part of what gives that irresistible golden crust.

Cooking Tips & Techniques

Making crispy overnight sourdough focaccia isn’t complicated, but a few techniques can really make your loaf shine. First, the overnight fermentation is key—it develops flavor and texture naturally without extra effort. You know that tangy depth you get from artisan breads? That’s the sourdough starter working its magic over hours.

Don’t rush the stretch and fold step. It’s gentle but crucial for gluten development, giving the bread structure without toughening it. And when dimpling the dough, don’t be shy—those pockets hold olive oil and rosemary, which caramelize and create that magical crispiness.

One common slip-up is under-oiling the pan or dough surface. Olive oil is your friend here; it prevents sticking and contributes to the crust’s crunch. Also, baking at a high temperature (450°F/230°C) produces that perfect golden crust. Lower temps will give a softer focaccia but miss out on that crisp exterior we’re after.

From experience, letting the bread cool on a wire rack after baking prevents sogginess underneath. Trying to slice it too soon can squash the crumb and make the crust chewy instead of crisp. Patience pays off—trust me on this.

And hey, multitasking works well here. While the dough rests overnight, I often prep a quick dinner like honey mustard chicken or a simple pasta, so the kitchen stays busy but stress-free.

Variations & Adaptations

This crispy overnight sourdough focaccia is a canvas for creativity, and I’ve tried a few variations that turned out great. For a seasonal twist, swapping fresh rosemary with thyme or oregano works beautifully in warmer months. If you want a hint of sweetness, try adding a tablespoon of honey or caramelized onions into the dough.

If you need a gluten-free option, you can experiment with a gluten-free flour blend, but note the texture will be different—less chewy, more crumbly. For a dairy-free and vegan version, this recipe already fits the bill since it uses only plant-based ingredients.

Another variation I love is pressing halved cherry tomatoes or thinly sliced olives into the dough before baking. It adds a juicy, savory pop. If you’re in a hurry, you can reduce the overnight fermentation to 4-6 hours with warmer water, but the flavor won’t be as developed.

For a different cooking method, try baking the focaccia on a preheated pizza stone for an even crisper bottom crust, or if you’re adventurous, pan-fry slices the next day for a crunchy snack.

Serving & Storage Suggestions

This focaccia is best served warm or at room temperature. I love tearing off chunks alongside a bowl of hearty soup or a fresh salad. It’s also fantastic as the base for sandwiches—imagine layering it with slow-cooker French dip beef and melted cheese from my French dip sandwich recipe.

Leftovers keep well in an airtight container for up to 3 days at room temperature. For longer storage, wrap tightly and freeze for up to 2 months. To reheat, pop slices in a toaster oven or under a broiler for a few minutes to revive that crispiness.

Flavors actually deepen after resting a day, so if you can resist, wait a bit before digging in. The rosemary and sea salt meld into the crumb, making each bite even more satisfying.

Nutritional Information & Benefits

FAQs

How active should my sourdough starter be for this recipe?

Your starter should be bubbly and have roughly doubled in size within 4-6 hours after feeding. This ensures enough yeast activity to give the focaccia good rise and flavor.

Can I use store-bought yeast instead of sourdough starter?

Yes, you can substitute with instant yeast (about 1 tsp) and skip the long fermentation. The texture will be different, less tangy, but still tasty. Adjust rising times accordingly.

Why is my focaccia not as crispy as I expected?

Make sure to use enough olive oil on the dough and pan, and bake at a high temperature like 450°F (230°C). Also, let it cool on a wire rack to avoid sogginess.

How do I store leftover focaccia to keep it fresh?

Store at room temperature in an airtight container for up to 3 days, or freeze wrapped tightly for up to 2 months. Reheat in a toaster oven or oven to restore crispness.

Can I add other toppings besides rosemary and sea salt?

Absolutely! Try olives, cherry tomatoes, caramelized onions, or even garlic for different flavor profiles. Just add them before baking after dimpling the dough.
