Crispy Rosemary Sourdough Focaccia Recipe Easy Homemade with Flaky Sea Salt

“Why can’t you just add rosemary right on top before baking instead of mixing it in the dough?” my friend asked me one lazy Sunday afternoon as I was fussing over my sourdough focaccia. I started to explain why that wouldn’t work — then stopped. Honestly, her idea was exactly right.

That afternoon, I abandoned my usual method of folding rosemary into the dough and instead sprinkled it liberally over the surface, paired with a generous dusting of flaky sea salt. The result? A crispy rosemary sourdough focaccia that was so much better than I expected. The golden crust snapped delightfully beneath my fingers, and the aroma of fresh rosemary mingled with tangy sourdough filled the kitchen in the most inviting way.

It was one of those rare moments when you realize the student has taught the teacher something valuable. I mean, I had been making focaccia for years, convinced my way was the only way. But that afternoon, with a cracked mixing bowl and a half-forgotten timer buzzing in the background, I learned that sometimes simplicity and intuition win out.

Since then, this recipe has stuck with me — it’s become my go-to for weekend baking, for impressing guests without stress, and for those lazy evenings when you want something crunchy, flavorful, and satisfying. Maybe you’ve been there, too, wanting to make something delicious at home that’s just a little bit special.

What Ingredients You Will Need

This crispy rosemary sourdough focaccia uses simple, wholesome ingredients to create a bright, flavorful bread with a satisfyingly crisp exterior. Most are pantry staples or easy to find at your local grocery store.

• Active sourdough starter (about 100g / 3.5oz) – This is the heart of your bread, giving it that signature tang. I usually use my bubbly, mature starter fed about 6-8 hours before baking.
• Warm water (350ml / 1.5 cups) – Lukewarm, to help activate the starter and mix the dough.
• All-purpose flour (500g / 4 cups) – I recommend a quality brand like King Arthur for consistent results.
• Fine sea salt (10g / 2 tsp) – For seasoning the dough itself.
• Extra virgin olive oil (50ml / 3 tbsp) – Adds richness to the dough and helps develop the crispy crust.
• Fresh rosemary (2-3 tbsp, chopped) – Fresh is best, but dried rosemary works in a pinch (use about half the amount).
• Flaky sea salt (to sprinkle on top) – This final touch gives you those delightful crunchy bursts of saltiness on the crust.

If you want a dairy-free or vegan-friendly version, this recipe is naturally free of dairy and eggs. You can swap the all-purpose flour for bread flour or a mix of whole wheat if you prefer a heartier texture. Just keep in mind that higher protein flours might change the hydration a bit.

Seasonal note: In summer, sometimes I like to add a handful of cherry tomatoes pressed lightly into the dough before baking. It’s a nice way to add a pop of color and freshness.

Equipment Needed

• Large mixing bowl: For combining the dough ingredients. Glass or plastic works fine.
• Dough scraper or spatula: Helpful for folding and handling sticky dough without too much mess.
• Kitchen scale: Highly recommended for measuring flour and water accurately—makes a big difference in bread baking results.
• Proofing basket or bowl: Optional but useful if you want a more structured rise before baking.
• Baking sheet or cast iron pan: A rimmed baking sheet works great; a cast iron pan adds extra crispiness if you have one.
• Oven thermometer: Not essential but helpful for maintaining consistent baking temperature if your oven runs hot or cold.

For budget-friendly options, you can use a clean kitchen towel to cover the dough during proofing instead of a plastic wrap. A pizza stone can also be swapped in to help with even heat distribution if you don’t have a cast iron pan.

Preparation Method

1. Activate your starter: Make sure your sourdough starter is bubbly and active, ideally fed 6-8 hours before baking. This usually means it’s doubled in size and has a pleasant, tangy aroma. (About 15 minutes prep)
2. Mix the dough: In a large mixing bowl, combine 100g (3.5oz) active starter, 350ml (1.5 cups) warm water, and 500g (4 cups) all-purpose flour. Stir with a spatula or your hand until just combined — the dough will be shaggy and sticky. (10 minutes)
3. Add salt and olive oil: Sprinkle 10g (2 tsp) fine sea salt over the dough, then drizzle in 50ml (3 tbsp) olive oil. Mix thoroughly until the salt and oil are incorporated. The dough should feel soft and slightly tacky but elastic. (5 minutes)
4. Bulk fermentation with folds: Cover the bowl loosely with a clean kitchen towel or plastic wrap. Let the dough rest at room temperature for 3-4 hours. Every 30 minutes for the first 2 hours, perform a set of stretch and folds: wet your hand, gently stretch one edge of the dough up and fold it over the rest. Repeat on all four sides. This builds gluten structure. (3-4 hours, mostly hands-off)
5. Prepare the pan: Drizzle olive oil generously on a rimmed baking sheet or cast iron pan (about 2 tbsp). Transfer the dough to the pan, gently pressing it out with your fingers to fit the pan — don’t worry about perfect shape. (10 minutes)
6. Final proof: Cover the dough again and let it rest for 1-2 hours until it’s puffed up and airy. You should see bubbles forming beneath the surface. (1-2 hours)
7. Add rosemary and sea salt: Preheat your oven to 450°F (230°C). Before baking, sprinkle 2-3 tbsp chopped fresh rosemary evenly over the dough and scatter flaky sea salt on top. Press the rosemary lightly into the dough to help it stick. (5 minutes)
8. Bake: Place the pan in the oven and bake for 20-25 minutes until the focaccia is deep golden brown and crispy around the edges. The top should shimmer with olive oil and the rosemary will be fragrant. (20-25 minutes)
9. Cool and serve: Remove from oven and let cool for 10 minutes before slicing. The crust will stay crispy and the crumb soft and chewy. (10 minutes)

Pro tip: If your focaccia seems underbaked inside, tent it loosely with foil and bake for another 5 minutes. You want a hollow sound if you tap the bottom.

Cooking Tips & Techniques

One of the trickiest parts of sourdough focaccia is getting that perfect crispy crust without drying out the interior. Here’s what I’ve learned from multiple batches:

• Don’t skip the stretch and folds: This step builds gluten strength and traps air bubbles, giving you that open, chewy crumb.
• Use plenty of olive oil: Coating your pan well and drizzling on top before baking helps develop a golden, crispy crust.
• Press the rosemary into the dough: This keeps the herb from burning and ensures its flavor infuses the crust.
• Keep the oven hot: A high temperature is essential for that signature crust; 450°F (230°C) is ideal.
• Be patient with proofing: Rushing this step can lead to dense bread. If your kitchen is cold, give it extra time or proof near a warm spot.
• Flaky sea salt is your best friend: It adds bursts of texture and flavor—don’t substitute with fine salt on top.

One time, I forgot to fold the dough during bulk fermentation (honestly, I got distracted by a phone call). The focaccia turned out dense and chewy instead of light and airy. Lesson learned: those folds really matter! Also, timing the final proof and preheating the oven simultaneously helps you get the timing just right without rushing.

Variations & Adaptations

This crispy rosemary sourdough focaccia is versatile enough for all kinds of twists:

• Garlic and herb: Mix minced garlic with the rosemary or brush garlic-infused olive oil on top before baking.
• Seasonal toppings: Add halved cherry tomatoes, olives, or caramelized onions before baking for extra flavor and color.
• Gluten-free option: Substitute the all-purpose flour with a trusted gluten-free blend. Note that hydration adjustments may be needed.
• Whole wheat or rye: Swap up to half the flour with whole wheat or rye flour for a nuttier, denser crumb.
• Different herbs: Try thyme, oregano, or even fresh basil for a different herbal profile.

Personally, I once tried adding a touch of grated Parmesan cheese on top alongside the rosemary and flaky salt. It gave the focaccia a salty, savory edge that was absolutely addictive. Feel free to experiment and make this recipe your own!

Serving & Storage Suggestions

This focaccia is best served warm, straight from the oven or at room temperature. I love slicing it thick and serving it alongside a simple salad, some creamy hummus, or even my favorite creamy tomato soup for dipping.

To store, wrap cooled focaccia tightly in plastic wrap or place it in an airtight container. It keeps well at room temperature for 1-2 days. For longer storage, freeze slices individually wrapped in parchment paper and a freezer bag — they thaw quickly and can be reheated in a toaster oven to regain crispness.

Reheating tip: Warm in a 375°F (190°C) oven for about 5-7 minutes. This helps refresh the crust’s crunch without drying the crumb. Over time, the flavors from the rosemary and sea salt deepen, so leftovers can taste even better the next day.

FAQs

Can I use dried rosemary instead of fresh?

Yes, you can substitute dried rosemary but use about half the amount since dried herbs are more concentrated. Sprinkle it on top just before baking for best flavor.

How do I know when my sourdough starter is ready to use?

Your starter should be bubbly, doubled in size, and have a pleasant tangy smell. It usually takes 6-8 hours after feeding at room temperature.

Can I make this focaccia without a sourdough starter?

While this recipe is designed for sourdough, you can use commercial yeast as a substitute. However, the flavor and texture will differ significantly.

How long can I store leftover focaccia?

Store wrapped at room temperature for 1-2 days or freeze slices for up to 3 months. Reheat in a hot oven to refresh the crust.

What’s the best way to get a crispy crust?

Use plenty of olive oil on the pan and top, bake at a high temperature (450°F/230°C), and don’t skip the flaky sea salt on top. Baking in a cast iron pan also helps crispiness.
