Sourdough Focaccia: Rosemary & Sea Salt

There are few culinary delights that capture the essence of simple perfection quite like a truly great focaccia. And when that focaccia is born from the magic of a sourdough starter, it transcends mere bread and becomes an experience. Imagine a golden-crusted slab, incredibly airy and chewy within, its surface dotted with deep, oil-filled craters, fragrant with fresh rosemary and brightened by the sparkle of flaky sea salt. This isn’t just a recipe; it’s an invitation to bring the soul of an Italian bakery right into your own kitchen, all thanks to the vibrant life within your sourdough starter.

My journey with sourdough focaccia began with a quest for the ultimate snack bread. Something versatile enough to accompany a hearty soup, cradle a sandwich, or simply be torn and dipped in olive oil, but with that distinct tang and digestibility only sourdough can provide. The challenge? To create a focaccia that was consistently bubbly, impossibly tender, and bursting with flavor, without being overly complicated. After countless loaves, tweaks, and early morning baking sessions, I’ve finally perfected a method that delivers exactly that.

This sourdough focaccia recipe is designed for both the seasoned sourdough baker and those just starting to explore its wonders. It embraces a high hydration dough, giving you that coveted open crumb, and utilizes a longer fermentation process for unparalleled depth of flavor. The hands-on time is surprisingly minimal; most of the work is done by time and your active starter. Get ready to fill your home with an aroma that will make mouths water and hearts sing. This isn’t just baking; it’s pure joy.

Ingredients

• 100g active sourdough starter (fed and bubbly, passed the float test)
• 350g warm water (around 90-95°F / 32-35°C)
• 400g strong bread flour (unbleached, high protein content for structure)
• 10g fine sea salt (for the dough)
• 30g extra virgin olive oil (plus more for the pan and drizzling)
• 2 sprigs fresh rosemary (leaves stripped and roughly chopped)
• 1-2 teaspoons flaky sea salt (for topping)

Step-by-Step Instructions

1. Feed Your Starter: Ensure your sourdough starter is active and fed at its peak before you begin. Ideally, feed it 4-6 hours before you plan to mix the dough. It should be bubbly, aromatic, and pass the float test (a small spoonful floats in water).

2. Autolyse (Optional, but Recommended): In a large mixing bowl, combine the bread flour and warm water. Mix until no dry streaks of flour remain. It will be shaggy. Cover the bowl with a damp cloth or plastic wrap and let it rest for 30 minutes to 1 hour. This step allows the flour to fully hydrate and gluten to begin developing, leading to a more extensible dough.

3. Mix the Dough: Add your active sourdough starter and the fine sea salt to the autolysed dough. Mix thoroughly, either by hand or with a stand mixer on low speed, until all ingredients are well combined and the dough starts to come together. This might take 5-7 minutes. The dough will be quite sticky.

4. First Stretch and Fold: Incorporate the 30g of extra virgin olive oil into the dough. This is best done by pouring it over the dough and gently folding it in until absorbed. Now, begin the first series of stretch and folds. With wet hands, gently grab a portion of the dough from the edge of the bowl, stretch it upwards, and fold it over itself towards the center. Rotate the bowl and repeat this action 3-4 times, until you’ve gone all the way around. This helps build gluten strength. Cover the bowl and let it rest for 30 minutes.

5. Bulk Fermentation (4-6 rounds of Stretch and Folds): Over the next 3-4 hours, perform 3-5 more sets of stretch and folds every 30-45 minutes. Each time, you’ll notice the dough becoming smoother, stronger, and more elastic. After the last set of stretch and folds, cover the bowl and let the dough continue its bulk fermentation at room temperature (around 70-75°F / 21-24°C) until it has significantly increased in volume, roughly 50-75%, and appears bubbly and alive. This could take anywhere from 8 to 14 hours depending on your starter’s activity and ambient temperature. Watch the dough, not the clock.

6. Prepare the Pan: Generously coat a 9×13 inch baking pan (or similar size) with extra virgin olive oil. Don’t be shy; a good layer prevents sticking and contributes to that crispy bottom crust. Pour about 2-3 tablespoons of oil into the pan and spread it evenly.

7. Transfer and Shape: Gently turn the fermented dough out into the prepared pan. The dough will be very jiggly and bubbly. Carefully stretch it to fill the pan, trying not to deflate it too much. If it resists, let it rest for 10-15 minutes, then continue stretching. Once stretched, drizzle a little more olive oil over the top, cover the pan loosely with plastic wrap, and place it in the refrigerator for a cold proof. This cold proof can be anywhere from 2 hours to 12 hours (or even up to 24 hours for deeper flavor development). It helps develop flavor and makes the dough easier to handle.

8. Dimpling and Topping: Remove the pan from the refrigerator about 1-2 hours before baking to allow it to come to room temperature. Preheat your oven to 450°F (230°C). With well-oiled fingers, gently but firmly dimple the entire surface of the focaccia dough, pressing your fingers almost all the way down to the bottom of the pan. This creates those iconic pockets for olive oil and toppings. Drizzle generously with more extra virgin olive oil, sprinkle with the chopped fresh rosemary and flaky sea salt.

9. Bake: Place the focaccia in the preheated oven. Bake for 25-30 minutes, or until the top is deeply golden brown and the bottom is crisp. If you have a baking steel or stone, preheat it and place the pan directly on it for an even crisper bottom.

10. Cool and Serve: Once baked, carefully remove the focaccia from the pan immediately and transfer it to a wire rack to cool slightly. This prevents the bottom from becoming soggy. Serve warm, torn into rustic pieces, and perhaps with a little extra drizzle of your finest olive oil. Enjoy!

Pro Tips for Focaccia Perfection

Crafting the perfect sourdough focaccia is an art that benefits from a few seasoned insights. These tips will elevate your baking experience and ensure a consistently delicious result every time.

• Know Your Starter: The most crucial element is an active, well-fed sourdough starter. A weak starter will lead to a dense, flat focaccia. Look for a starter that doubles in size within 4-6 hours after feeding, is bubbly throughout, and easily floats in water. Adjust your feeding schedule to ensure it’s at its peak before mixing.
• Hydration is Key: Sourdough focaccia is a high-hydration dough. This means it will be sticky, but don’t be tempted to add too much extra flour. The high water content is what gives focaccia its characteristic open, airy crumb. Embrace the stickiness; wet hands and a dough scraper are your best friends.
• Gentle Handling: After the bulk fermentation, the dough is filled with precious gases that create those beautiful bubbles. When transferring the dough to the pan and spreading it, be as gentle as possible to avoid deflating it. Think of it as coaxing, not forcing.
• The Art of Dimpling: Dimpling isn’t just for looks; it pushes the gas bubbles evenly through the dough, creating a more uniform crumb, and forms those wonderful wells that hold the olive oil and toppings. Don’t be afraid to press firmly with oiled fingertips, almost to the bottom of the pan.
• Embrace the Cold Proof: While you can bake focaccia after a shorter room temperature proof, a long cold proof in the refrigerator (8-24 hours) is a game-changer. It significantly deepens the flavor, making the sourdough tang more complex, and also makes the dough easier to handle and dimple. Plus, it allows you to fit baking into your schedule.
• Quality Olive Oil: Since olive oil is such a prominent flavor and texture component in focaccia, use a good quality extra virgin olive oil. Not just for drizzling, but for oiling the pan and mixing into the dough. Its fruity, peppery notes will shine through.
• Topping Variations: While rosemary and sea salt are classic, feel free to experiment! Try thinly sliced red onion, cherry tomatoes (halved), olives, garlic slivers, or even a sprinkle of Parmesan cheese. Add these during the dimpling stage.
• Temperature Matters: Ensure your oven is fully preheated to the correct temperature. A hot oven creates a strong initial burst of steam, which helps with oven spring and the development of a crispy crust.

Chef’s Secret Tip

For an absolutely show-stopping focaccia with an irresistible sheen and even deeper flavor, do not skimp on the final drizzle of olive oil just before baking. After dimpling, use a truly exceptional, peppery, and robust extra virgin olive oil. Pour it generously into the dimples; it will pool and slowly absorb, creating pockets of richness that caramelize beautifully in the oven and impart an incredible depth of flavor and a luscious texture to the finished bread.

Frequently Asked Questions (FAQs)

Baking with sourdough can sometimes bring up questions, especially when venturing into new recipes like focaccia. Here are some common queries and their answers to help you master this delicious bread.

Q: My sourdough starter isn’t very active. Can I still make this focaccia?

A: While technically you *could* try, a weak starter will likely result in a very dense, flat focaccia with poor oven spring and minimal open crumb. For the best results, it’s crucial to use an active, bubbly starter that has been fed and has proven its vitality (e.g., passes the float test). Take a few days to strengthen your starter with consistent feeding before attempting this recipe.

Q: My dough is incredibly sticky. Is this normal?

A: Yes, absolutely! This focaccia is a high-hydration dough, meaning it contains a significant amount of water. This is intentional and contributes to its characteristic airy, open crumb. Embrace the stickiness! Wet your hands when performing stretch and folds, and use a dough scraper to manage it. Avoid adding extra flour, as this will lead to a denser focaccia.

Q: Can I use all-purpose flour instead of bread flour?

A: While you can technically make focaccia with all-purpose flour, I highly recommend using strong bread flour. Bread flour has a higher protein content, which is essential for developing the strong gluten network needed to trap the gases from your sourdough starter, resulting in a more open, chewy crumb and better structure in a high-hydration dough like focaccia.

Q: Why do I need to cold proof the dough? Is it really necessary?

A: A cold proof in the refrigerator serves several important purposes. Firstly, it significantly deepens the flavor of the focaccia, allowing the sourdough culture to develop more complex notes. Secondly, it slows down the fermentation process, making the dough easier to handle and giving you more flexibility in your baking schedule. Lastly, it can contribute to a better crust and a more even crumb structure. While not strictly “necessary” if you’re in a rush (you could do a shorter room temp final proof), it truly elevates the final product.

Q: My focaccia came out dense and not very bubbly. What went wrong?

A: Several factors could contribute to a dense focaccia:

1. Weak Starter: As mentioned, a weak starter won’t provide enough lift.
2. Under-Proofed Dough: The dough didn’t have enough time to ferment and develop sufficient gas bubbles during bulk fermentation. It needs to increase significantly in volume.
3. Over-Proofed Dough: Conversely, an over-proofed dough can collapse in the oven because the gluten structure has weakened too much.
4. Improper Handling: Deflating the dough too much when transferring or dimpling can release gases needed for rise.
5. Oven Temperature: An oven that isn’t hot enough can prevent proper oven spring.

Review your steps, especially regarding starter activity and fermentation signs.

Q: How do I store leftover sourdough focaccia?

A: Focaccia is best enjoyed on the day it’s baked. However, leftovers can be stored at room temperature in an airtight container or wrapped tightly in plastic wrap for 2-3 days. For longer storage, slice the focaccia and freeze it in an airtight freezer bag for up to 3 months. Reheat slices in a toaster oven or regular oven for a few minutes until crisp again.

Q: What are some good ways to serve sourdough focaccia?

A: Sourdough focaccia is incredibly versatile! It’s fantastic simply torn and dipped in olive oil, balsamic vinegar, or a pesto. It makes an excellent sandwich bread, perfect for deli meats, fresh mozzarella, tomatoes, and basil. Serve it alongside a hearty bowl of soup or stew, with grilled meats, or as part of an antipasto platter. It’s also wonderful with scrambled eggs or as a base for bruschetta.
