Sourdough Focaccia with Rosemary & Sea Salt

Introduction

A warm welcome to a timeless loaf
As a baker who leans into slow fermentation and simple ingredients, I find sourdough focaccia endlessly satisfying. This style of focaccia celebrates texture and seasoning: an airy, open crumb that gives way to crisp, olive oil–kissed edges and the bright, aromatic lift of fresh rosemary. The interplay of tang from a live starter with the fruity warmth of extra-virgin olive oil creates a loaf that feels both rustic and refined.

I love this recipe for its adaptability — it slots into busy weekends as easily as into a leisurely, focused bake day. The dough rewards hands-on time with delicate bubbles and deep, savory notes that store-bought breads rarely capture. The finishing scatter of flaky sea salt and the floral pine of rosemary provide quick, high-impact seasoning that makes every bite memorable.

In this article I’ll walk you through ingredient choices, technique pointers to coax an open crumb, and thoughtful serving ideas from sandwiches to antipasti boards. Expect down-to-earth guidance written from the perspective of someone who tests recipes until they sing: practical tips that marry science with feel, and sensory cues so you can trust sight, touch, and aroma at every stage rather than only watching a timer.

Why You’ll Love This Recipe

Simple ingredients, layered flavor
This focaccia is beloved because it turns a handful of everyday pantry staples into an expressive, textured loaf. The fermentation builds a nuanced sourness that complements the richness of olive oil and the herbaceous lift of rosemary. The contrast between a pillowy interior and a golden, slightly crisp exterior is the kind of bread experience that makes people linger at the table.

Beyond taste and texture, the method is forgiving. The dough is forgivingly slack and sticky — a quality that encourages big bubbles and a tender crumb rather than dense heaviness. Gentle handling at shaping keeps those bubbles intact. The final dimpling step is meditative and practical: it traps olive oil and toppings, ensuring each forkful delivers seasoning and moisture.

This focaccia is also versatile. It shines as a vehicle for bold sandwich fillings, a companion to soups and salads, or as a centerpiece on a grazing platter. Because components like tomatoes or olives can be added at the end, the loaf adapts to seasonal produce. If you appreciate bread that tastes like effort yet feels effortless at service, this recipe will become a go-to.

Flavor & Texture Profile

What to expect on the palate
Biting into this sourdough focaccia delivers a layered sensory experience. The first impression is the sheen of olive oil and the pop of flaky salt, creating a savory surface that highlights the herbs. Underneath, the crumb should be open and springy, with large irregular holes that indicate well-developed gluten and gentle handling during shaping.

A well-made sourdough starter contributes a subtle, tangy backbone that balances the bread’s richness. The olive oil flavors the crumb as well as the crust, imparting a silky mouthfeel and a slightly fruity aroma. Fresh rosemary lends a piney, citrus-adjacent brightness that cuts through the oiliness, while flaky sea salt adds bursts of briny crunch.

Texture is all about contrast: soft interior bubbles that dissolve on the tongue paired with a thin, crisp edge that yields a satisfying bite. If you prefer more chew or a heartier crust, adjust your oven finish slightly to deepen browning; if you favor pillowy softness, a lighter bake will preserve more tenderness. Overall, this focaccia aims for balance — a savory olive oil richness anchored by sourdough depth and lifted by herbs and salt.

Gathering Ingredients

Choose well to let the dough shine
Selecting quality raw ingredients is where great focaccia begins. Use a strong bread flour with good protein to build structure, an active mature sourdough starter for flavor complexity, and a fruity extra-virgin olive oil for aroma and mouthfeel. Fine sea salt integrates into the dough while flaky sea salt provides that finishing crunch. Fresh rosemary is far superior to dried here — it adds bright herb notes and a fragrant garnish.

• 500 g strong bread flour
• 350 g lukewarm water
• 150 g active sourdough starter (100% hydration)
• 60 ml extra-virgin olive oil
• 10 g fine sea salt
• 1 tsp honey or sugar (optional)
• 2 tbsp olive oil for the pan
• Fresh rosemary sprigs
• Flaky sea salt for finishing
• Cherry tomatoes, halved (optional)
• Sliced olives (optional)

When assembling your mise en place, measure ingredients precisely for repeatable results and keep the starter at peak activity. Small choices — a brighter olive oil, flaky finishing salt, or plump, ripe tomatoes — make an outsize difference in the finished loaf.

Preparation Overview

Technique: gentle, patient, and tactile
This focaccia rewards patience and a light touch. The dough benefits from an initial hydration rest to allow the flour to fully absorb water and begin gluten formation without forceful mixing. When the starter is incorporated, develop strength through a sequence of gentle folds rather than aggressive kneading; this encourages an open crumb and preserves the gas pockets that form during fermentation.

Pay attention to feel at every stage: the dough should be sticky but cohesive, stretching in sheets rather than tearing instantly. Bulk fermentation is a time to observe volume gains and bubble development rather than to watch the clock; signs of a well-fermented dough include a glossy surface and visible bubbling beneath the skin. When moving the dough to the pan, be generous with oil — the fat helps the dough spread and creates the celebrated crust-to-crumb contrast.

The final bench rest and dimple step are where texture and topping placement come together. Dimples create pockets that capture olive oil and toppings so flavors concentrate in each bite. For best results, use fingertips to dimple deeply and distribute herbs and finishing salt with a light hand. These tactile cues will guide you as much as any timing instruction.

Cooking / Assembly Process

Step-by-step instructions

1. Activate starter: Ensure your starter is bubbly and at peak activity before beginning.
2. Autolyse: Mix the strong bread flour and lukewarm water until no dry streaks remain; cover and allow to rest.
3. Incorporate starter: Add the active sourdough starter and optional honey, mixing until incorporated.
4. Add salt and oil: Sprinkle the fine sea salt over the dough, add olive oil, and fold until the dough feels cohesive and sticky but not shaggy.
5. Bulk ferment and folds: Bulk ferment at room temperature, performing a series of stretch-and-folds during the early phase to build strength; let the dough develop visible bubbles and elasticity.
6. Prepare the pan: Generously oil a rectangular baking tray and transfer the dough, turning it to coat with oil; gently stretch to fill the tray.
7. Bench proof and dimple: After a short bench rest, use fingertips to dimple the dough deeply all over, then drizzle remaining olive oil across the surface and tuck rosemary sprigs and optional toppings into the dimples.
8. Final proof and chill option: Allow the tray to proof until puffy and jiggly; for deeper flavor, refrigerate overnight and then bring back to room temperature before baking.
9. Bake: Preheat the oven with a baking stone or inverted tray as desired, and bake until the top is golden-brown and the edges are crisp. Remove, add an optional final drizzle of olive oil, and cool slightly before slicing.

Throughout assembly and baking, watch for visual and tactile cues: surface sheen, buoyant bubbles, and golden coloration are your guides. Adjust oven placement if the top browns faster than the base to preserve the ideal crust-to-crumb ratio.

Serving Suggestions

Ways to enjoy this focaccia
This focaccia is wonderfully versatile and can be presented in a range of casual and composed ways. Tear it and dip into quality olive oil and balsamic for a rustic starter, or slice it thick to build sandwiches that hold up to hearty fillings. The bread’s open crumb and olive oil profile also pair beautifully with soft cheeses and cured meats on a sharing board.

For a simple, crowd-pleasing approach, lightly warm slices and top with fresh, bright ingredients like arugula and ripe tomato, or layer with roasted vegetables for a vegetarian sandwich that balances texture and flavor. If serving with soups or stews, use the focaccia to sop up broths; its absorbent crumb soaks up liquid while the seasoned crust provides contrast.

When entertaining, present torn pieces with small bowls of condiments: herb-infused olive oil, tapenade, or a whipped ricotta with lemon zest. The loaf also shines when transformed into a breakfast or brunch component — think open-faced toasts with sautéed greens and a soft egg. Keep servings warm or at ambient temperature to show off the bread’s texture and aroma at their best.

Storage & Make-Ahead Tips

Plan ahead and refresh for best results
Sourdough focaccia is forgiving when it comes to make-ahead strategies. You can prepare the dough and allow a long, cool proof to develop deeper flavor, then bring it back to temperature before finishing and baking. Refrigeration slows fermentation and enhances complexity, while a shorter, room-temperature approach yields a fresher, tangier finish.

Once baked, store the loaf wrapped on the counter for short-term use, or slice and freeze portions for longer keeping. To revive texture, a brief run in a hot oven or toaster will crisp the crust and revive the interior’s tenderness. For sandwiches, slice from chilled or room-temperature focaccia and reheat lightly if you prefer a toasted bite.

If you anticipate leftovers, consider turning stale slices into croutons or breadcrumbs — the seasoned surface adds instant flavor to salads and dishes. When reheating, a gentle heat keeps the crumb hydrated while restoring the outer crispness; avoid microwaving for extended periods as that can collapse the crumb and soften the crust excessively. Thoughtful storage and refresh steps preserve the loaf’s signature contrasts so every serving feels purposeful.

Frequently Asked Questions

Common questions and quick answers

• Can I use all-purpose flour instead of bread flour?
  All-purpose flour can be used in a pinch, but bread flour gives better structure and a more open crumb due to its higher protein content.
• What if my starter is sluggish?
  Feed and wait for active bubbling before using; a lively starter ensures reliable fermentation and flavor development.
• How do I know when the dough is ready to shape?
  Look for a dough that has visible bubbling, elasticity, and a glossy surface; gentle finger tests should show some resistance and spring.
• Can I add other toppings?
  Yes — thinly sliced onions, roasted garlic, or grated cheese are great additions, but add delicate items near the end of proof to avoid burning.
• Is it okay to refrigerate the dough overnight?
  Absolutely; cold fermentation deepens flavor. Bring the dough back to room temperature before baking so it becomes airy and jiggly again.

Final note: If you have more questions about technique, feel, or troubleshooting, I encourage you to try a test bake and observe the dough’s cues — sight, touch, and aroma are your best teachers in the kitchen.
