Sourdough Blueberry Focaccia – Light, Juicy, and Perfectly Crisp

This sweet-meets-savory focaccia brings together the tang of sourdough and the burst of warm blueberries. The edges turn golden and crisp, while the center stays airy and tender. A sprinkle of sugar and lemon makes the fruit shine, and a drizzle of olive oil keeps everything plush.

It’s just as good for brunch as it is for an afternoon snack. Serve it warm and watch it disappear.

Why This Recipe Works

• Sourdough starter adds flavor and lift without relying on commercial yeast, giving the dough depth and a gentle tang.
• High hydration creates an open, bubbly crumb and that signature focaccia lightness.
• Cold ferment builds flavor and makes the dough easier to handle, while improving oven spring.
• Olive oil and sugar balance the savory dough with fruity sweetness and crisp edges.
• Lemon zest and flaky salt brighten the blueberries and keep the overall flavor lively.

Ingredients

• 425 g (3 1/3 cups) bread flour
• 325 g (1 1/3 cups) room-temperature water
• 120 g active, bubbly sourdough starter (100% hydration)
• 10 g fine sea salt
• 40 g extra-virgin olive oil, plus more for the pan and drizzling
• 200–250 g fresh blueberries (about 1 1/2 cups)
• 2–3 tbsp granulated sugar, divided
• Zest of 1 lemon
• 1 tsp vanilla extract (optional)
• Flaky sea salt, to finish

Instructions

1. Mix the dough: In a large bowl, whisk the water and starter until mostly combined. Add flour and salt.

   Stir with a spatula until no dry bits remain. Rest 20–30 minutes (autolyse).

2. Add the oil: Pour in 30 g olive oil and fold it into the dough with damp hands. It will feel slippery at first, then start to absorb.

   Cover and rest 20 minutes.

3. Strengthen the dough: Perform 3–4 sets of stretch-and-folds every 20–30 minutes. To do this, grab one edge of the dough, stretch up, and fold over. Rotate the bowl and repeat 4–6 times per set.

   The dough should become smoother and bouncy.

4. Bulk ferment: Cover and let rise at room temperature until puffy and increased by about 60–75%, 2–4 hours depending on temperature. It should jiggle and show bubbles at the edges.
5. Cold proof (optional but recommended): Lightly oil the bowl, cover, and refrigerate 8–12 hours for flavor and easier handling.
6. Prepare the pan: Generously oil a 9×13-inch pan (or a large sheet pan for thinner focaccia) with 2–3 tbsp olive oil. Turn the dough into the pan and gently stretch it.

   If it resists, rest 10 minutes and stretch again until it reaches the corners.

7. Top with blueberries: Toss blueberries with 1–2 tbsp sugar, lemon zest, and vanilla if using. Dimple the dough with oiled fingertips, pressing straight down to create pockets. Scatter the blueberries evenly, letting some nestle into the dimples.

   Sprinkle another 1 tbsp sugar over the top.

8. Final proof: Let the dough rise, uncovered, until very puffy and bubbly, 45–75 minutes depending on room temp. It should shake like a soft pillow when you jiggle the pan.
9. Bake: Preheat oven to 425°F (220°C). Drizzle 1–2 tbsp olive oil over the top and finish with a pinch of flaky salt.

   Bake 22–28 minutes, until the top is golden and the edges are deeply crisp. Rotate once for even color.

10. Cool and serve: Rest in the pan 10 minutes, then transfer to a rack. Serve warm.

    Optional: dust with a touch more lemon zest or a light drizzle of honey right before serving.

How to Store

• Room temperature: Keep in an airtight container for up to 2 days. Recrisp in a 350°F (175°C) oven for 8–10 minutes.
• Freezer: Wrap tightly and freeze for up to 1 month. Reheat from frozen at 375°F (190°C) for 12–15 minutes.
• Avoid the fridge: It dries out bread.

  Freeze instead if storing longer than 2 days.

Why This is Good for You

• Sourdough fermentation can make gluten easier to digest for some people and may improve mineral absorption.
• Blueberries bring antioxidants, fiber, and natural sweetness, reducing the need for heavy sugar.
• Olive oil adds heart-friendly fats and helps you feel satisfied with smaller portions.

Common Mistakes to Avoid

• Underproofing: If the dough isn’t puffy before baking, it will be dense. Wait for visible bubbles and a jiggly feel.
• Too little oil: Skimping on oil leads to sticking and a dry crust. The pan should be well-coated.
• Overloading fruit: Too many blueberries can weigh down the dough and make soggy spots.

  Stick to about 1 1/2 cups.

• Cold berries on cold dough: If both are very cold, you’ll slow oven spring. Let the dough warm slightly during final proof.
• Cutting too soon: Let it rest at least 10 minutes so the crumb sets and juices settle.

Alternatives

• Flour swap: Use up to 20% whole wheat or spelt for nuttier flavor. Add a splash more water if needed.
• Citrus twist: Try orange zest instead of lemon for a warmer note.
• Herb upgrade: Add fresh thyme or rosemary leaves with the berries for a sweet-savory vibe.
• Sugar finish: Sprinkle turbinado sugar on top for extra crunch.
• No sourdough: Use 7 g instant yeast, increase water to 360 g, and skip the cold proof.

  Rise times will shorten.

FAQ

How do I know my starter is ready?

It should be bubbly, doubled in volume, and pass the float test in water. If it’s sluggish or smells overly sour, give it a feeding and wait a few hours.

Can I use frozen blueberries?

Yes. Use them straight from the freezer and toss with sugar and zest.

Work quickly to avoid staining the dough and expect a minute or two more bake time.

Why is my focaccia pale?

You likely need a hotter oven or a bit more sugar and oil on top. Make sure the oven is fully preheated and bake until deep golden around the edges.

Can I bake this in a cast-iron skillet?

Absolutely. Use a 12-inch well-oiled skillet.

The crust will be extra crisp, and bake time may be a touch shorter.

Is this more sweet or savory?

It’s lightly sweet with a savory backbone from olive oil and salt. Think of it as a fruit-studded bread that works with coffee or cheese.

Final Thoughts

Sourdough blueberry focaccia is simple, joyful baking: minimal shaping, big flavor, and a stunning pan of golden bubbles and juicy berries. With a little time and a healthy pour of olive oil, you’ll get a bakery-style result at home.
