Blueberry Sourdough Loaf
The Ultimate Guide to Rustic Blueberry Sourdough Bread
There is something profoundly magical about pulling a loaf of sourdough out of the oven, hearing the crust sing as it cools, and slicing into it to reveal a hidden galaxy of colors. This Blueberry Sourdough Bread is not just a baked good; it is a work of edible art. With its rugged, golden-brown crust and a crumb speckled with bursts of jammy, violet blueberries, this loaf transforms a standard breakfast into a gourmet experience.
Integrating fresh or frozen fruit into lean dough can be intimidating for many home bakers. The fear of inhibiting gluten development or creating a gummy interior often deters people from experimenting. However, with the right technique—specifically lamination—you can achieve a loaf that is light, airy, and beautifully stained with natural purple swirls without compromising the structural integrity of the bread. This guide will walk you through every step, ensuring your success in creating a bakery-quality loaf at home.
Whether you are a seasoned sourdough veteran or a brave beginner looking to level up your game, this recipe offers a perfect balance of challenge and reward. The sweetness of the berries pairs perfectly with the natural tang of the fermentation, making it an ideal vessel for salted butter, cream cheese, or simply enjoyed plain while still warm.

Ingredients
To create this masterpiece, you need high-quality staples. The simplicity of the ingredient list means quality matters.
- Bread Flour (500g): High protein content (12-14%) is crucial here to support the heavy inclusions of fruit.
- Water (350g): Filtered water is best to ensure chlorine doesn’t affect your starter.
- Active Sourdough Starter (100g): Your starter should be bubbly, active, and at its peak.
- Salt (10g): Essential for flavor and tightening the gluten structure.
- Blueberries (150g): Fresh or frozen work. If using frozen, do not thaw them beforehand to prevent streaking too early.
- Lemon Zest (Optional): The zest of one lemon adds a brightness that cuts through the starch.
- Honey or Sugar (20g): A small amount helps balance the tartness of the berries, though it is optional.
- Rice Flour: For dusting the banneton prevents sticking, especially with a wet, fruity dough.
Instructions
Phase 1: Autolyse and Mixing
- Autolyse: In a large mixing bowl, combine the bread flour and 325g of the water (hold back 25g for later). Mix until no dry flour remains. Cover with a damp cloth and let it rest for 1 hour. This strengthens the gluten network before fermentation begins.
- Add Leaven: Add your active sourdough starter to the dough. Dimple it in with wet fingers to incorporate.
- Add Salt: Dissolve the salt in the reserved 25g of water and pour it over the dough. Squeeze and fold the dough to fully integrate the salt and starter. The dough may separate slightly but will come back together as you mix.
Phase 2: Bulk Fermentation
- Stretch and Folds: Perform 3 sets of stretch and folds spaced 30 minutes apart. To do this, grab one side of the dough, stretch it up high, and fold it over the center. Rotate the bowl and repeat for all four sides.
- Lamination (Adding Berries): After the third fold, wet your counter. Turn the dough out and stretch it into a large, thin rectangle. Sprinkle the blueberries (and lemon zest if using) evenly over the surface. Fold the dough into a packet (thirds, like a letter) to trap the berries inside. Place back in the bowl.
- Coil Folds: Perform 2 more sets of coil folds spaced 45 minutes apart to gently build strength without crushing the berries.
- Rest: Let the dough rise until it has increased in volume by about 50-75%. The dough should look jiggly and show bubbles on the surface.
Phase 3: Shaping and Cold Proof
- Preshape: Gently turn the dough onto a lightly floured surface. Shape into a loose round. Let it bench rest for 20 minutes.
- Final Shape: Flip the dough so the smooth side is down. Fold the bottom up, sides in, and top down, stitching it tight. Flip it over and create surface tension by dragging it against the counter. be careful not to tear the skin where berries are protruding.
- Cold Retard: Dust your banneton generously with rice flour. Place the dough upside down (seam side up) into the basket. Cover with a plastic bag or shower cap and refrigerate for 12–16 hours. This develops flavor and makes the dough easier to score.
Phase 4: Baking
- Preheat: Place your Dutch oven into the oven and preheat to 500°F (260°C) for at least 45 minutes.
- Score: Remove the dough from the fridge and turn it out onto a piece of parchment paper. Dust off excess flour. Using a lame or razor blade, score the dough. A simple single expansion score works best for fruit breads.
- Bake: Carefully lower the dough into the hot Dutch oven. Cover with the lid. Bake for 20 minutes.
- Finish: Remove the lid. Lower the temperature to 450°F (230°C). Bake for another 20–25 minutes until the crust is deep golden brown and the berries are bubbling.
- Cool: Let the bread cool on a wire rack for at least 2 hours before slicing. Cutting it too early will result in a gummy texture as the interior is still cooking with residual heat.
Tips for Success
Handling High Hydration with Fruit
Fruit adds water to the dough. If your blueberries are very fresh and juicy, you might want to slightly reduce the initial water in the recipe by 10-20g. If using frozen berries, toss them in a teaspoon of flour before laminating to help them adhere to the dough layers.
The “Purple Streak” Effect
If you want distinct swirls rather than a completely purple dough, mix gently. Add the berries during lamination rather than the initial mix. Mixing berries in at the start will break them down, dyeing the entire loaf gray-purple. Lamination keeps the pockets distinct and vibrant.
Knowing When It’s Done
Because of the moisture from the fruit, this bread often takes 5-10 minutes longer to bake than a plain loaf. Tap the bottom—it should sound hollow. Alternatively, use a digital thermometer; the internal temperature should reach at least 208°F (98°C).
Flavor Variations
Once you master the base technique, the sky is the limit. Here are a few combinations to try:
- Lemon Poppyseed: Add zest of 2 lemons and 2 tbsp poppyseeds with the berries.
- White Chocolate Blueberry: Add 100g of white chocolate chips during lamination for a decadent dessert loaf.
- Savory Twist: Swap blueberries for olives and rosemary for a Mediterranean version.
- Spiced Berry: Add 1 tsp of cinnamon and a pinch of nutmeg to the flour mix for a warm, autumnal flavor profile.
Serving Suggestions
This bread is a centerpiece on its own, but pairing it correctly can elevate the experience:
- French Toast: The absolute best use for day-old blueberry sourdough. The custard soaks into the open crumb, and the caramelized berries warm up beautifully.
- Ricotta Toast: Slather a thick slice with whipped ricotta, drizzle with honey, and top with crushed pistachios.
- Grilled Cheese: Use a sharp white cheddar or brie. The savory cheese contrasts perfectly with the sweet berry pockets.
Troubleshooting Common Issues
Why is my dough impossible to shape?
It may be over-fermented or the fruit added too much moisture. Ensure you are doing enough folds to build strength, and don’t be afraid to use a bench scraper to help create tension.
Why did my bread burn on the bottom?
Sugars from the fruit can caramelize and burn faster than plain dough. Place a baking sheet on the rack below your Dutch oven to deflect direct heat, or sprinkle cornmeal under the parchment paper.
Why is the crumb gummy?
This usually happens if you cut into the bread while it is still warm. Sourdough needs a long cooling period to set the starch. Patience is the hardest ingredient, but the most necessary one!
Making artisan sourdough is a journey of patience and observation. Every kitchen is different, from humidity to ambient temperature, so learn to watch the dough, not just the clock. This Blueberry Sourdough is a rewarding challenge that brings the bakery experience right into your home kitchen. Enjoy the crackle of the crust and the burst of berry flavor in every bite!
