A Blueberry Sourdough Loaf is the perfect balance between rustic artisan bread and soft, slightly sweet bakery-style loaf. It combines the tangy depth of natural sourdough with bursts of juicy blueberries, creating a bread that works beautifully for breakfast, brunch, or even dessert. The process takes time, but most of it is passive fermentation, which is what gives sourdough its signature flavor and airy texture.
Below is a complete step-by-step guide to help you make it successfully at home.
🫐 Blueberry Sourdough Loaf (Step-by-Step Guide)
🥖 Ingredients
For the dough:
- 500 g bread flour (or strong all-purpose flour)
- 350 g water (room temperature)
- 100 g active sourdough starter (bubbly and fed)
- 10 g salt
- 20 g honey or sugar (optional, for slight sweetness)
For the filling:
- 150–200 g fresh or frozen blueberries
- 1–2 tbsp flour (to coat blueberries and prevent bleeding)
- Optional: lemon zest or cinnamon for extra flavor
⏳ Step 1: Prepare Your Active Starter
Your sourdough starter must be active and bubbly before you begin.
- Feed your starter 4–6 hours before baking.
- It should double in size and pass the “float test” (a spoonful floats in water).
- This ensures strong fermentation and good rise.
🥣 Step 2: Mix the Dough (Autolyse Phase)
In a large bowl:
- Mix flour and water until no dry flour remains.
- Cover and let rest for 30–60 minutes.
👉 This step allows gluten to develop naturally, making the dough smoother and easier to stretch later.
🍞 Step 3: Add Starter and Salt
After resting:
- Add the active sourdough starter.
- Mix well using your hands or a dough scraper until incorporated.
- Add salt and honey (if using).
- Knead gently for 3–5 minutes until the dough becomes elastic.
👉 The dough will feel sticky at first but will strengthen over time.
⏲️ Step 4: Bulk Fermentation (First Rise)
- Cover the bowl with a damp cloth or plastic wrap.
- Let it rise for 4–6 hours at room temperature.
During the first 2 hours:
Perform stretch and folds every 30–45 minutes:
- Grab one side of the dough, stretch it upward, and fold it over.
- Rotate the bowl and repeat 4 times per session.
👉 This builds strength and traps air, giving the loaf its airy structure.
