Crispy Sourdough Focaccia Recipe with Rosemary and Flaky Sea Salt Easy Homemade Guide

My friend Mark had flat-out refused to eat focaccia for over a decade. I mean, he called it “just bland bread with herbs” every single time it came up at dinner parties. Then one rainy Thursday evening, I whipped up this crispy sourdough focaccia with rosemary and flaky sea salt just for myself and found him sneaking pieces off the cooling rack when he thought no one was looking. Honestly, I wasn’t even trying to convince him; it just happened.

The sizzle of olive oil bubbling in the pan had already filled the kitchen with this irresistible aroma, mixing with the piney scent of fresh rosemary. I’d made a bit of a mess kneading the dough (flour everywhere, naturally), and halfway through, my phone rang, which meant I lost track of time. But when that golden crust emerged from the oven, all my distractions melted away. Mark’s surprise face when he took his first bite? Priceless.

Maybe you’ve been there—skeptical about focaccia, thinking it’s just another bread. But this recipe, with its crunchy edges, chewy sourdough crumb, and that just-right sprinkle of flaky sea salt, changed the game for us. It’s the kind of bread that makes you pause and savor, the kind that sticks around in your kitchen and your heart for many meals to come.

Why You’ll Love This Recipe

I’ve tested countless focaccia recipes over the years, but this one stands apart because it brings together the best of sourdough’s tangy depth with a perfectly crisp crust and a fragrant rosemary finish. Here’s why it might become your go-to bread too:

• Quick & Easy: From mixing the dough to pulling it out of the oven takes about 3 hours, but most of that is hands-off rising time—perfect for a lazy weekend afternoon.
• Simple Ingredients: You probably have these basics in your pantry already—flour, sourdough starter, olive oil, and herbs.
• Perfect for Entertaining: Whether it’s a casual dinner or a potluck, this focaccia impresses without stress.
• Crowd-Pleaser: Even Mark, the focaccia skeptic, can’t get enough of it.

This isn’t some ordinary focaccia; the sourdough fermentation adds a subtle tang that balances beautifully with the rosemary’s earthiness and the punch of sea salt. I like to think of it as my little twist on an old classic, the kind of recipe that rewards patience with every bite. It’s the kind of bread that makes you close your eyes and savor the moment—that’s why it keeps showing up on my table, time and time again.

What Ingredients You Will Need

This recipe uses straightforward, wholesome ingredients to deliver big flavor and texture without fuss. Most are pantry staples, but a few quality touches really make the difference.

• For the dough:
• Unbleached all-purpose flour, 3 cups (360 g) – I recommend King Arthur for consistent texture
• Sourdough starter, active and bubbly, ½ cup (120 ml) – homemade or store-bought
• Warm water, 1 ¼ cups (300 ml) – around 80°F/27°C to encourage fermentation
• Fine sea salt, 2 tsp (10 g)
• Extra virgin olive oil, 3 tbsp (45 ml) – plus more for drizzling and pan
• For the topping:
• Fresh rosemary sprigs, 2 tbsp (chopped) – fresh is best for aroma
• Flaky sea salt, 1 tbsp (such as Maldon) – adds that signature crunch and burst of saltiness

If you’re short on fresh rosemary, dried herbs can work in a pinch but won’t have the same punch. I’ve tried using olive oil infused with garlic for a twist—just adjust the salt to balance the flavors. For a gluten-free version, try substituting with a blend of almond and tapioca flours, though the texture will differ.

Equipment Needed

To make this crispy sourdough focaccia with rosemary and flaky sea salt, you’ll need a few essentials, but nothing too fancy:

• A large mixing bowl – glass or stainless steel works well, and easy cleanup is a bonus
• A dough scraper or spatula – great for handling sticky sourdough dough without frustration
• A baking sheet or rimmed roasting pan – I prefer using a 9×13-inch (23×33 cm) pan for a thick, airy focaccia
• Kitchen towel or plastic wrap – to cover the dough during rising
• Oven – preheated to 450°F (230°C) for that signature crisp crust

Optional but helpful: a silicone baking mat or parchment paper to prevent sticking. I once tried baking directly on a pizza stone, but the pan gives the focaccia that classic dimpled texture and prevents it from drying out. If you don’t have a dough scraper, a butter knife or sturdy spatula can do the job in a pinch.

Preparation Method

1. Mix the dough (10 minutes): In your large bowl, combine 3 cups (360 g) flour and 2 tsp (10 g) fine sea salt. Add ½ cup (120 ml) active sourdough starter and 1 ¼ cups (300 ml) warm water. Stir with a dough scraper or wooden spoon until a shaggy, sticky dough forms. Don’t worry if it looks rough—that’s normal. Cover with a towel and let it rest for 30 minutes to hydrate.
2. Stretch and fold (5 minutes): After resting, wet your hands lightly and gently stretch one edge of the dough up and fold it over the center. Repeat this on all four sides. This develops the gluten for a better crumb. Cover again for 30 minutes.
3. Repeat stretch and fold twice more: Give the dough two more rounds of stretch and folds at 30-minute intervals. By the last round, the dough should feel smoother and springy.
4. First rise (2 hours): After the final fold, cover the bowl tightly and leave the dough to rise at room temperature until it doubles in size, about 2 hours. You’ll notice bubbles forming—this means your sourdough is working its magic.
5. Prepare the pan: Generously oil your 9×13-inch (23×33 cm) baking pan with 1 tbsp (15 ml) olive oil. Gently transfer the dough into the pan, using oiled hands to spread it out. Don’t worry if it resists; just give it a gentle push.
6. Second rise (45 minutes): Cover the pan with a towel and let the dough relax and rise again for 45 minutes. It should puff up and fill the pan.
7. Dimpling the dough: Using your fingers dipped in olive oil, press dimples all over the surface of the dough. This step traps the olive oil and rosemary, creating those signature pockets of flavor and texture.
8. Top and drizzle: Sprinkle 2 tbsp chopped fresh rosemary evenly over the dough, then drizzle 2 tbsp (30 ml) olive oil on top. Finish with 1 tbsp flaky sea salt for that satisfying crunch.
9. Bake (20-25 minutes): Place the pan in a preheated oven at 450°F (230°C). Bake for 20 to 25 minutes, rotating halfway, until the crust is deep golden and crispy. The smell will be irresistible.
10. Cool and serve: Let the focaccia cool in the pan for 10 minutes before transferring to a wire rack. Slice into squares and enjoy warm or at room temperature.

If your focaccia feels too dense, your starter might not have been active enough—try feeding it a day before. Also, don’t skip the dimpling; it’s what gives focaccia that lovely texture and flavor pockets. Trust me, you’ll want to get your fingers oily!

Cooking Tips & Techniques

Making focaccia is part science, part art, and a bit of luck—let me share some tips I’ve picked up the hard way:

• Use an active sourdough starter: If your starter isn’t bubbly and fresh, your dough won’t rise well. Feed it 4-6 hours before you start baking.
• Don’t skimp on olive oil: It’s key for that golden crust and deep flavor. I drizzle extra right before baking and sometimes after, too.
• Embrace the sticky dough: Sourdough focaccia dough is wetter and stickier than bread dough. Resist the urge to add more flour; use oiled hands to handle it instead.
• Patience is your friend: The long rises develop flavor and texture. If you’re short on time, you can speed it up with warmer water, but the flavor won’t be the same.
• Watch your oven temperature: A hot oven is essential for that crispy crust. If your focaccia isn’t browning, your oven might be cooler than it says.

I once baked a batch without dimpling (don’t ask), and it came out flat and chewy, not the airy, crispy delight I wanted. Lesson learned! Also, multitasking while baking can be tricky—set timers and prep everything before the oven’s on to avoid burnt edges.

Variations & Adaptations

This focaccia recipe is a fantastic base to customize based on your mood or ingredients on hand:

• Cheesy twist: Sprinkle grated Parmesan or mozzarella over the rosemary before baking for a gooey, savory upgrade.
• Seasonal toppings: Swap rosemary for thyme or sage in fall, or scatter cherry tomatoes and olives for a Mediterranean vibe.
• Gluten-free option: Use a gluten-free flour blend designed for bread and add xanthan gum for structure. Expect a softer crumb.
• Garlic infusion: Press thin slices of garlic into the dough before baking for a fragrant punch.

I once tried folding in caramelized onions into the dough—huge hit! Just be sure to reduce added salt slightly to balance flavors. You can also bake this focaccia on a pizza stone for a crisper bottom crust, but be careful when transferring the dough.

Serving & Storage Suggestions

This focaccia is best served warm or at room temperature, fresh from the oven or later in the day. I like to tear it up alongside a big bowl of soup or use it as a base for sandwiches. A drizzle of extra olive oil or a smear of soft cheese turns it into a quick snack.

Store leftover focaccia tightly wrapped at room temperature for up to 2 days or refrigerate for up to 5 days. To freeze, wrap well in plastic and foil; it keeps for up to 3 months.

Reheat gently in a 350°F (175°C) oven for 5-7 minutes to revive the crispness. Microwaving will soften the crust, which is okay if you want softer bread, but not ideal if you crave that crunch. Flavors actually deepen after a day or two, so leftover focaccia can be even better.

Nutritional Information & Benefits

The sourdough fermentation process can help improve digestibility and nutrient absorption compared to regular bread. Olive oil adds heart-healthy monounsaturated fats, while rosemary contributes antioxidants and a lovely aroma that might even boost digestion.

This recipe is naturally vegetarian and can be made vegan if you ensure your sourdough starter contains no dairy. It’s not gluten-free unless adapted, so those with sensitivities should try the suggested substitutions.

Conclusion

If you’ve ever thought focaccia was just “meh,” this crispy sourdough focaccia with rosemary and flaky sea salt might just change your mind—like it did for Mark. It’s flavorful, crusty, and surprisingly simple to make at home with everyday ingredients.

Feel free to tweak the herbs, toppings, or flour to suit your taste. Honestly, that’s part of the fun—making this recipe your own. I love how it fills the kitchen with warmth and gets everyone reaching for seconds without me even asking.

FAQs

• Can I use instant yeast instead of sourdough starter? Yes, but the flavor will be less tangy. Use about 1 tsp instant yeast and reduce rising time accordingly.
• How do I know when my sourdough starter is ready to use? It should be bubbly, doubled in size, and pass the float test (a spoonful floats in water).
• Can I make the dough ahead of time? Absolutely! Refrigerate the dough after the first rise for up to 24 hours and bake when ready.
• Why isn’t my focaccia crispy? Make sure your oven is hot enough (450°F/230°C) and use plenty of olive oil on top and in the pan.
• What’s the best way to store leftover focaccia? Wrap tightly and keep at room temperature for up to 2 days or freeze for longer storage.
