Crispy Overnight Sourdough Focaccia Recipe with Rosemary and Sea Salt Perfect for Easy Homemade Bread

Introduction

When a last-minute dinner guest showed up just as I was about to call it quits on a long day, the only thing I had worth baking was a half-used sourdough starter and a bag of flour gathering dust. No fancy ingredients, no time for elaborate prep—just that starter, some rosemary sprigs I’d forgotten in the fridge, and coarse sea salt. Honestly, I wasn’t sure if it would come together or end up a sad, dense brick. But somehow, this crispy overnight sourdough focaccia with rosemary and sea salt emerged, golden and fragrant, transforming that night’s chaotic moment into a proud kitchen win.

The smell of olive oil mingling with toasted rosemary and flaky salt still lingers in my memory. The crust crackled under my fingers, and the crumb was airy but chewy, exactly what I’d hoped for from a slow, overnight rise. This recipe wasn’t born in a neat, planned moment—it was a rescue operation that turned into a staple. And you know, that’s the magic of sourdough focaccia; it’s forgiving, simple, and honestly pretty addictive once you get the hang of it.

What Ingredients You Will Need

This crispy overnight sourdough focaccia uses simple, wholesome ingredients to deliver bold flavor and a satisfying texture without any fuss. Most are pantry staples or easily found at any grocery store, and a few fresh touches bring the recipe to life.

• Active sourdough starter (about 100g / 3.5 oz) – I recommend a bubbly, well-fed starter like King Arthur or your own homemade culture.
• All-purpose flour (400g / 3 1/4 cups) – Can swap for bread flour for a chewier texture, or use 50% whole wheat for nuttiness.
• Water (300ml / 1 1/4 cups), lukewarm – This hydrates the dough for that open crumb.
• Extra virgin olive oil (60ml / 1/4 cup), plus more for drizzling – Use a fruity, high-quality olive oil for best flavor.
• Sea salt flakes (2 teaspoons) – The crunch and burst of saltiness on top makes all the difference.
• Fresh rosemary (2 tablespoons, finely chopped) – Adds that classic piney herb aroma; you can substitute with thyme if you like.
• Fine salt (1 teaspoon) – For the dough itself.

You can easily adapt this recipe depending on what you have on hand. For example, if you don’t have fresh rosemary, dried works but use less since it’s more intense. Or, if you need a gluten-free option, try swapping the flour with a gluten-free blend and adjust hydration accordingly. The beauty is in the simplicity and flexibility.

This focaccia pairs beautifully with savory dishes like hearty stews or fresh salads, and I often serve it alongside my healthy chicken veggie skillet wraps for a wholesome meal that feels both rustic and special.

Equipment Needed

• Mixing bowl: A large bowl to mix and proof the dough. Glass or stainless steel works best.
• Bench scraper or spatula: Handy for folding the dough and transferring it cleanly.
• 9×13-inch baking pan or similar: I prefer a metal pan for crispier edges but glass works too.
• Kitchen towel or plastic wrap: To cover the dough during its overnight rise.
• Oven: Preheated to 450°F (230°C). A convection oven works great if you have one.

For those on a budget, a simple Pyrex dish and a mixing bowl you already own will do just fine—no need for fancy bread pans or proofing baskets. I’ve tried using a cast iron skillet for focaccia, which gives it a lovely crust but requires careful oiling and heat management. If you’re new to bread baking, a basic set of kitchen scales to measure ingredients by weight really helps with consistency.

Preparation Method

1. Activate your sourdough starter: Make sure your starter is bubbly and active, fed about 4-6 hours before starting. This ensures good rise.
2. Mix the dough: In a large bowl, combine 400g (3 1/4 cups) all-purpose flour, 1 teaspoon fine salt, and 300ml (1 1/4 cups) lukewarm water. Stir to combine until just mixed. Add 100g (3.5 oz) active sourdough starter and 2 tablespoons olive oil. Mix with a spatula until a shaggy dough forms (~5 minutes).
3. First rest (autolyse): Cover the bowl with a towel or plastic wrap and let rest for 30 minutes. This hydrates the flour and starts gluten development.
4. Stretch and fold: After the rest, wet your hands and stretch one side of the dough up and fold it over itself. Repeat on all four sides. This strengthens the dough without kneading.
5. Bulk fermentation overnight: Cover the bowl and place it in the fridge for 12-16 hours. This slow fermentation builds flavor and gives focaccia its characteristic open crumb.
6. Prepare the pan: Generously oil a 9×13-inch (23×33 cm) pan with olive oil.
7. Shape the dough: Remove dough from fridge and gently transfer to the pan. Using your fingers, press and stretch the dough to fill the pan. Don’t worry if it resists—just let it rest for 10 minutes and try again. You want the dough evenly spread but not too thin.
8. Final proof: Cover loosely and let dough rise at room temperature for 1-2 hours until puffy and soft.
9. Preheat oven: Heat oven to 450°F (230°C).
10. Dimple and season: Using your fingertips, poke dimples all over the dough surface. Drizzle 2 tablespoons olive oil evenly, sprinkle with 2 tablespoons chopped fresh rosemary and 2 teaspoons sea salt flakes.
11. Bake: Place the pan in the oven and bake for 20-25 minutes until golden brown and crisp on top. The edges should be visibly crunchy and the bottom browned.
12. Cool slightly and serve: Let the focaccia cool in the pan for 10 minutes before slicing. This helps the crumb set and makes cutting easier.

Pro tip: If your dough feels sticky or resistant when shaping, a quick rest for 10 minutes can help it relax. And when baking, keep an eye on the crust towards the end—too dark and you lose that delicate balance of crisp and tender.

Cooking Tips & Techniques

Getting that perfect crispy overnight sourdough focaccia crust is all about temperature and timing. Here’s what I’ve learned from many batches:

• Use a well-fed starter: Your sourdough starter should be active and bubbly. A sluggish starter means less rise and denser bread.
• Hydration is key: This recipe’s relatively high water content helps create those lovely air pockets inside. Don’t skimp on the water.
• Don’t rush the fermentation: Overnight in the fridge allows flavor to develop slowly. I tried shortening this and noticed a loss in complexity.
• Oil your pan generously: This not only prevents sticking but also crisps the edges beautifully.
• Dimples aren’t just decorative: They trap olive oil and seasonings, infusing the bread with flavor and moisture.
• Watch your oven temp: 450°F (230°C) is ideal for a crust that’s crisp but not burnt. Use an oven thermometer if you can.
• Rest before slicing: If you cut too soon, the crumb can be gummy. A brief cooling period helps.

One mistake I made early on was overworking the dough—focaccia dough should be handled gently to keep those air bubbles intact. And multitasking during the final proof helps—start your mise en place for dinner while the dough puffs up, so you’re ready to bake as soon as it’s done.

Variations & Adaptations

While this rosemary and sea salt focaccia is a classic, it’s also a wonderful base for creativity. Here are some ways to switch things up:

• Herb variations: Swap rosemary for fresh thyme, oregano, or basil for a different herbal twist.
• Cheesy focaccia: Sprinkle grated Parmesan or shredded mozzarella on top before baking for a melty, savory finish.
• Olive and garlic: Add chopped kalamata olives and thinly sliced garlic to the dough or topping for Mediterranean vibes.
• Gluten-free option: Use a gluten-free flour blend and adjust water as needed; note that texture will differ but still delicious.
• Different cooking methods: If you don’t want to bake in a pan, try shaping the dough on a pizza stone for a thinner crust focaccia.

Personally, I once added caramelized onions and a sprinkle of chili flakes for a sweet-spicy combo that disappeared in minutes. For a brunch spread, pairing this focaccia with soft scrambled eggs and a fresh fruit salad makes a simple, satisfying meal that’s sure to impress—much like my go-to sweet treat, the creamy strawberry cream puff bars.

Serving & Storage Suggestions

This focaccia is best served warm or at room temperature. The crust is at its crispiest fresh from the oven, but the crumb softens beautifully if left to rest. It pairs wonderfully with dips like olive tapenade, hummus, or a simple herb-infused olive oil.

For a main meal, serve alongside soups, stews, or your favorite roasted veggies. It’s a natural companion to dishes like the healthy chicken veggie skillet wraps that bring wholesome flavor to the table.

To store, wrap the focaccia tightly in plastic wrap or place in an airtight container. It keeps well at room temperature for up to 2 days, and you can refrigerate for up to a week. For longer storage, slice and freeze in zip bags for up to 3 months.

When reheating, pop slices in a toaster oven or under the broiler for a few minutes to revive the crisp crust. Avoid microwaving, which can turn it gummy. Over time, the flavors mellow and deepen—a small bonus if you like your bread with a touch of tang.

Nutritional Information & Benefits

One serving (about 1/8 of the focaccia) contains approximately:
