Sourdough Focaccia with Olive Oil and Herbs

Sourdough focaccia is one of the most satisfying, deeply comforting, and versatile artisan breads enjoyed across many parts of the world. Its popularity comes from its ultra-fluffy, high-rising interior, intensely crispy olive-oil-fried bottom crust, signature deep finger dimples, and the way it delivers a generous amount of complex tangy notes paired with aromatic herbs in every single bite without feeling heavy or overly rich. A square of freshly baked sourdough focaccia can be enjoyed as a quick weekday snack, a post-workout comfort meal, a light yet filling sandwich base, a make-ahead flatbread for the week, a party dinner centerpiece, or simply whenever a nutritious, satisfying savory dish is desired.

Unlike a basic quick focaccia made with only commercial instant yeast, this version layers in multiple flavor dimensions, a vibrant long wild fermentation, and a well-balanced combination of textures to create something that tastes as good as it performs as a high-satisfaction artisanal meal. This comprehensive recipe explains every stage of preparation in detail, from selecting and activating the starter to stretching, dimpling, topping, and baking the final golden crust.

Introduction

Focaccia has long been a beloved staple across many kitchens, valued for its versatility, ease of preparation, and ability to be customized in countless ways. The sourdough version elevates this classic by layering in extra depth from natural wild fermentation, high hydration levels, sea salt, and a generous pool of rich olive oil, while keeping the interior structure open, pillowy, and full of large air bubbles with a slow overnight cold rise. This style of flatbread has become especially popular for home bakers, Italian food enthusiasts, and anyone looking for a gut-friendly bread that keeps them feeling light throughout the day.

The dish relies on mixing and autolysing flour to gluten perfection, then combining it with an active sourdough starter and a variety of fresh, fragrant herbs for texture and aroma. This characteristic makes sourdough focaccia especially rewarding to prepare at home because the dough requires zero complex shaping or kneading skills and bakes beautifully in a standard baking pan. The resulting flatbread is naturally hearty, airy, and deeply satisfying.

Homemade sourdough focaccia requires a handful of fresh and pantry ingredients, basic kitchen equipment, and a generous amount of preparation time. Even beginners can successfully prepare it with a little patience.

Yield

This recipe produces one large 9×13-inch rectangular thick-pan focaccia, yielding approximately 8 to 12 generous bakery-style squares.

Preparation Time

Active Prep & Autolyse: 45 minutes
Bulk Fermentation (with stretch & folds): 4 to 5 hours
Pan Proofing (Room Temp): 2 to 4 hours (OR 12-24 hours cold overnight fridge fermentation)
Baking Time: 25 to 30 minutes
Total Time: Approximately 8 hours (same-day) or 24 hours (overnight cold ferment method)

Main Ingredients

4 cups (500g) unbleached strong bread flour (high protein ensures a tall, airy rise)
1 ½ cups (375g) filtered water (room temperature, establishing a high 75% hydration)
½ cup (100g) active, bubbly sourdough starter (fed 4-6 hours prior to mixing)
2 teaspoons (12g) fine sea salt (for the internal dough)
⅓ cup (80g) high-quality extra virgin olive oil (divided for the pan, dough, and topping)
1 tablespoon fresh rosemary needles, roughly chopped
1 teaspoon coarse flaky sea salt (like Maldon, for the final crunch topping)

Additional Optional Ingredients

3-4 garlic cloves, thinly sliced into chips
½ cup cherry tomatoes, cut in half and pressed into the dough
¼ cup kalamata olives, pitted and halved
1 teaspoon dried oregano or Italian seasoning mix
1 small red onion, thinly sliced into rings
A handful of grated Parmesan or Pecorino Romano cheese scattered before baking
A drizzle of chili-infused hot honey immediately out of the oven
Fresh baby basil leaves added after baking
Sun-dried tomato strips packed in oil
A few thin slices of fresh yellow lemon and zucchini for a floral look

Equipment Required

Large glass or ceramic mixing bowl
Digital kitchen scale (highly recommended for baking precision)
Measuring cups and spoons
Metal or glass 9×13-inch baking pan (cast-iron or dark metal pans produce the crispiest bottom)
Plastic wrap or a damp kitchen towel
Silicone spatula or dough scraper
Pastry brush
Wire cooling rack

Choosing the Perfect Sourdough Starter

The quality of the starter directly affects the final rise, giant bubble formation, and flavor depth of the focaccia. Selecting and timing the right starter is therefore extremely important.

Choose an active, fed sourdough starter that has doubled or tripled in volume, shows plenty of bubbles on the surface and sides, and passes the “float test” (a teaspoon of starter floats easily in a cup of water). A starter fed with a mix of rye and unbleached white flour tends to produce an even more vibrant fermentation network.

Avoid using a sluggish, cold discard straight from the fridge without feeding, as it will make the focaccia heavy, flat, and dense, and avoid using an over-ripened starter that has begun to fall back down, which can break down the gluten structure and make the dough soupy.

Preparing and Autolysing the Dough

Autolyse Method (preferred for lightest, cloud-like bubbles):

In a large mixing bowl, whisk together the filtered room-temperature water and the active sourdough starter until fully dissolved and milky.
Add the bread flour and stir with a spatula or your hands until a wet, shaggy dough forms and no dry flour streaks remain.
Cover the bowl with a damp cloth and let it rest undisturbed for 30 to 45 minutes. This process allows the flour to fully hydrate and naturally develops gluten before salt or oil are added.

Direct Mix Method (alternative):

Combine the flour, water, starter, fine salt, and 1 tablespoon of olive oil all at once in the bowl.
Knead vigorously for 8 minutes using a wet hand until a smooth, sticky dough forms.
Proceed directly to the bulk fermentation stage without a resting break.

Coil Folds and Bulk Fermentation

Because focaccia dough is very wet and sticky, traditional kneading on a countertop is avoided. Instead, we use gentle folds to build structural strength while trapping massive air pockets.

After the autolyse rest is complete, sprinkle the 2 teaspoons of fine sea salt and 1 tablespoon of extra virgin olive oil over the top of the dough.
Wet your hands with water. Reach under both sides of the dough, lift it upwards from the center until it detaches from the bowl, and let the loose edges fold underneath themselves. This is called a coil fold.
Rotate the bowl 90 degrees and repeat. Perform this 4 times until the dough forms a neat package. Cover and rest for 30 minutes.
Repeat this coil-fold sequence 3 to 4 more times over the next 2 hours. You will see the dough become incredibly smooth, glossy, and stretchy, with large air bubbles trapped just beneath the surface skin.
Let the dough sit undisturbed for the remaining bulk fermentation time (approx. 2 hours) until it feels puffy, light, and full of air.

The Pan Stretch and Extended Overnight Proofing

Pour 2 tablespoons of extra virgin olive oil into the bottom of your 9×13-inch baking pan, using your fingers or a brush to coat the bottom and all the sides thoroughly.
Gently tip the puffy bulk-fermented dough out of the bowl and directly into the oiled baking pan.
Take the edges of the dough and fold them into thirds over themselves (like a letter), then flip the dough package over so the smooth top side is facing up, coated in the pan’s olive oil.
Gently stretch the dough toward the four corners of the pan using the flats of your hands. It will likely shrink back—this is normal. Do not force it or pop the bubbles.
For Best Results (Overnight Method): Cover the pan tightly with plastic wrap and slide it into the refrigerator for 12 to 24 hours. The cold temperature relaxes the gluten completely, allowing the dough to fill the pan naturally while developing a deep flavor profile.
Alternative (Same-Day Method): Cover the pan and let it rest at room temperature for 3 to 4 hours until the dough expands to touch all four corners and looks incredibly jiggly.

The Dimpling and Topping Ritual

If you used the refrigerator method, remove the pan from the fridge 2 to 3 hours before baking to allow the dough to warm to room temperature and puff up completely.
Preheat your oven to $425^\circ\text{F}$ ($220^\circ\text{C}$) for at least 30 to 45 minutes to ensure an even, intense baking heat.
Drizzle another 2 tablespoons of extra virgin olive oil generously over the top surface of the puffy dough.
Scatter your chopped fresh rosemary needles and sliced garlic chips evenly over the oil-coated surface.
Oil your fingers generously. Hold your hands perpendicular to the dough, press your fingers straight down through the dough until you feel the hard bottom of the baking pan, and pull straight back up. Repeat this across the entire surface.
This action creates deep dimples, causing magnificent, giant sourdough bubbles to burst upward around your fingers. Finish by sprinkling the coarse flaky sea salt evenly across the surface.

Understanding Moisture and Oil Balance

Focaccia is inherently an oil-rich bread; the olive oil acts as both a flavor enhancer and a cooking medium.

The generous pool of olive oil at the bottom of the pan essentially fries the lower crust during baking, creating a golden, crunchy exterior that contrasts beautifully with the cloud-like interior texture.

If you choose to use wet toppings like fresh cherry tomatoes or onions, press them deeply into the dimples so they cook within the dough rather than releasing surface water that could make the top crust soggy.

Always ensure your oven is fully preheated; baking focaccia in a lukewarm oven will cause the dough to absorb the oil like a sponge rather than crisping up, resulting in a heavy, greasy bread.

Optional Add-In and Flavor Boosting Techniques

Some people enjoy a clean, classic herb focaccia while others prefer a heavily dressed, robust savory flatbread.

For a simple finish:

Use only the base extra virgin olive oil, fresh rosemary, and flaky sea salt for an authentic Genovese-style bread.

For a rustic garden finish:

Arrange thin colorful slices of bell peppers, cherry tomatoes, and red onions across the surface before dimpling to create a stunning “focaccia garden art” presentation.

For a fully loaded finish:

Combine all the optional techniques including pressing chopped kalamata olives and sun-dried tomatoes into the dimples, dusting the top with grated Parmesan cheese, and finishing with a heavy drizzle of hot chili honey right as it leaves the oven.

Making a Lighter Alternative Version

Many people enjoy a modified version of the flatbread that incorporates ancient grains or slightly alters the flour profile.

Replace 20% of the bread flour with whole wheat or spelt flour to add a nutty, complex whole-grain dimension and extra dietary fiber.

Reduce the final top oil layer by one tablespoon, relying instead on a misting of water combined with oil to create a lighter, steamed top crust structure.

Simple Plain Version

Many people enjoy the focaccia in its simplest form as a dinner table bread.

The combination of wild yeast fermentation, sea salt, and a basic olive oil coat produces an incredibly aromatic, satisfying bread on its own.

Simply omit the rosemary and garlic toppings, dimple the plain oiled dough with flaky salt, and bake to use as a premium sliced table loaf.

Traditional Baking Method

Place the oiled, dimpled, and topped pan directly onto the center rack of your preheated $425^\circ\text{F}$ ($220^\circ\text{C}$) oven.
Bake for 25 to 30 minutes, watching closely until the top is an even, deep golden-brown color and the edges look crisp and detached from the sides of the pan.
Remove from the oven. Let it sit in the hot pan for 5 minutes, then use a spatula to slide the focaccia out onto a wire cooling rack.

Elegant Presentation Method

Place the warm, whole rectangular focaccia onto a large, rustic live-edge wooden serving board.
Use a sharp chef’s knife or a heavy pizza wheel to slice the bread into uniform 3×3-inch squares.
Garnish the board with small dipping bowls filled with balsamic vinegar glaze, extra virgin olive oil, and a dish of marinated green olives.
This presentation works exceptionally well for interactive dinner parties, grazing tables, and elegant holiday entertaining.

Nutritional Information

Sourdough focaccia naturally contains:

Complex Carbohydrates (easily broken down and digestible due to the long wild fermentation process)
Healthy Monounsaturated Fats (from a generous amount of high-quality extra virgin olive oil)
B-Vitamins (Thiamin, Riboflavin, Niacin)
Iron and Selenium
Organic acids (which assist in gut health and lower the overall glycemic index of the bread)

The exact nutritional content varies depending on the specific ingredients, toppings, and quantities used.

Common Mistakes

Using regular vegetable or canola oil instead of high-quality extra virgin olive oil, which strips the focaccia of its signature Italian bakery flavor.
Rushing the fermentation process and dimpling the dough while it is still dense and cold, resulting in a flat, heavy, gummy bread without bubbles.
Using a lightweight, flimsy aluminum pan or a silicone mold, which fails to conduct heat properly and leaves the bottom crust pale, soft, and wet.
Over-handling or using a rolling pin to flatten the dough into the pan, which completely destroys the delicate air pockets built during bulk fermentation.
Leaving the baked focaccia to cool completely inside the metal baking pan, causing the bottom to trap steam and instantly turn soggy and soft.
Not oiling your fingers before dimpling, causing the wet dough to stick to your hands and tear open awkwardly.
Dimpling too shallowly; you must press your fingers firmly all the way to the bottom of the pan to create the classic wells that trap pockets of olive oil.
Using an under-fed or weak sourdough starter, which results in a dense crumb structure that fails to rise beautifully in the oven.
Overloading the top surface with too many heavy, wet toppings, weighing down the dough and preventing a proper fluffy oven spring.
Using dried rosemary instead of fresh needles; dried rosemary stays hard and wood-like during baking, poking the mouth uncomfortably.

Storage Guidelines

Store any leftover focaccia squares wrapped loosely in parchment paper or foil at room temperature for up to 2 days.
Avoid storing artisan focaccia in a sealed plastic bag, as this traps ambient moisture and ruins the crispy crust textures.
Never store focaccia in the refrigerator, as the cold environment crystallizes the starches and causes the bread to stale rapidly.
To reheat and perfectly restore the crispy bottom and fluffy interior, place pieces onto a baking sheet and heat in a $350^\circ\text{F}$ ($175^\circ\text{C}$) oven or toaster oven for 5 minutes. Avoid using a microwave, which turns the olive oil dough rubbery and tough.

Freezing Instructions

Sourdough focaccia freezes exceptionally well. Slice the completely cooled flatbread into individual square portions and place them onto a baking sheet to freeze solid for 1 hour. Once frozen, transfer the squares into a heavy-duty freezer zipper bag, squeezing out excess air, and freeze for up to 3 months. Reheat squares straight from the freezer by placing them directly into a hot toaster oven or standard oven at $375^\circ\text{F}$ ($190^\circ\text{C}$) for 8 to 10 minutes until sizzling and crispy.

Creative Uses for Leftover Focaccia

Slice stale focaccia squares horizontally, brush with a little extra oil, and toast to make the ultimate gourmet sandwich base.
Cut day-old focaccia into thick cubes, toss with sea salt, and bake for 12 minutes to create the crunchiest, olive-oil-infused soup croutons you’ve ever tasted.
Top individual stale squares with a spoonful of marinara sauce and mozzarella cheese, baking them briefly to create rapid “Focaccia Pizza” snacks.
Slice into long strips, toast until completely hard, and serve as savory artisan dipping sticks for charcuterie boards.
Pulse stale herb focaccia pieces in a food processor to create an incredible, fragrant herb-and-olive-oil breadcrumb mix perfect for coating chicken or fish.

Party Serving Suggestions

Time your baking so the focaccia comes out of the oven 20 minutes before guests arrive, filling your home with an intoxicating aroma of roasted garlic, olive oil, and rosemary.
Serve a massive platter of warm focaccia squares alongside a premium charcuterie spread featuring prosciutto di Parma, soft burrata cheese, hot capicola, and honey.
Pair the savory herb flatbread squares with crisp, chilled white wines like Pinot Grigio, dry sparkling Prosecco, or refreshing pale ales that cut through the rich oil beautifully.
Create a “Focaccia Sandwich Bar” for afternoon lunches, providing bowls of basil pesto, arugula, sliced tomatoes, and roasted red peppers so guests can build their own custom paninis.
For elegant cocktail hours, cut the focaccia into thin, bite-sized rectangles, top each piece with a small dollop of olive tapenade or a single sun-dried tomato, and pass them around as high-end Italian finger foods.
