Lemon Blueberry Sourdough Bread is a bright and flavorful twist on classic sourdough, combining tangy lemon zest and juicy blueberries with that chewy, crusty texture we all love. The sourdough starter brings a lovely depth of flavor, while the bursts of blueberry and refreshing lemon make each bite feel fresh and special.
I love how the lemon and blueberries balance the slight tang from the sourdough, creating a bread that’s both zesty and sweet in the best way. When I make this, I always make sure to use fresh blueberries if I can—they add that perfect pop of juiciness that frozen just can’t match. It’s one of those breads that’s fun to make because it feels a little fancy but comes together so naturally with the sourdough base.
My favorite way to enjoy this bread is toasted with a simple spread of butter or cream cheese. It also makes a wonderful base for breakfast French toast or just a snack with a cup of tea. Whenever I share this bread with friends, everyone’s eyes light up—it’s like a little burst of sunshine wrapped in a loaf!
Key Ingredients & Substitutions
Bread flour: This flour gives the bread structure and chewiness thanks to its high protein. You can swap for all-purpose flour but expect a softer crumb.
Sourdough starter: It’s the natural leavening here, adding flavor and texture. Use a bubbly, active starter for best rise. No starter? Try instant yeast but adjust fermentation times.
Lemon zest & juice: Fresh lemon zest provides bright citrus notes all through the bread. Use organic lemons if possible. Lemon juice is optional but helps boost the tanginess.
Blueberries: Fresh is best—they keep their shape and add juicy bursts. Frozen works too but thaw and drain to avoid too much moisture, which can affect dough.
Honey or sugar: Adds a subtle sweetness that balances the tart lemon and sourdough tang. This is optional based on your taste.
How Do You Fold in Blueberries Without Crushing Them?
Blueberries are delicate and can easily burst during mixing. To keep them mostly intact:
- Gently pat blueberries dry if frozen to remove extra moisture.
- After mixing the dough, use a folding motion rather than stirring—lift and fold the dough over the berries.
- Distribute the berries evenly but avoid pressing down or overworking the dough.
- Do the folding on a lightly floured surface or in the bowl, so dough doesn’t stick.
Taking it slow here helps you keep those pretty berry spots visible in every slice instead of turning the dough purple.
Equipment You’ll Need
- Large mixing bowl – I like it because it holds plenty of dough and makes mixing easier.
- Bench scraper or silicone spatula – helps fold in blueberries gently without damaging them.
- Dutch oven or baking stone – a heavy, oven-safe vessel that creates a crusty, bakery-style loaf.
- Proofing basket (banneton) or bowl lined with a floured towel – keeps your dough shaped as it ferments.
- Sharp knife or lame – for scoring the loaf before baking, allowing steam to escape and preventing cracks.
- Parchment paper – makes it easier to transfer the dough to the oven without losing shape.
Flavor Variations & Add-Ins
- Use fresh raspberries or blackberries instead of blueberries for a different berry flavor.
- Add vanilla extract or a pinch of cinnamon to the dough for a warm, fragrant twist.
- Mix in chopped nuts, like almonds or walnuts, for crunch and extra richness.
- Swirl in lemon curd or cream cheese before shaping for extra tang and creaminess.
How to Make Lemon Blueberry Sourdough Bread
Ingredients You’ll Need:
Main Dough:
- 500 g (about 4 cups) bread flour
- 350 g (about 1 1/2 cups) water, room temperature
- 100 g active sourdough starter (fed and bubbly)
- 10 g salt (about 1 3/4 teaspoons)
- Zest of 2 lemons (about 2 tablespoons)
- 1 tablespoon honey or sugar (optional)
- 1 teaspoon lemon juice (optional)
Add-Ins:
- 150 g fresh blueberries (about 1 cup)
How Much Time Will You Need?
This bread takes about 15 minutes to prepare, with a 45-minute initial rest, 2 hours of stretch-and-fold sessions, and 4 to 6 hours of fermenting time at room temperature. Overnight proofing in the fridge adds 8-12 hours for great flavor. Baking takes about 40-45 minutes, plus cooling time.
Step-by-Step Instructions:
1. Mix and Rest the Dough (Autolyse):
In a large bowl, combine the bread flour and water. Stir until all the flour is soaked and you have a shaggy dough. Cover the bowl and let it rest for 45 minutes to hydrate the flour fully and start gluten development.
2. Add Starter and Flavorings:
Add your active sourdough starter, salt, lemon zest, and honey or sugar and lemon juice if using. Mix everything well by hand or with a dough hook until smooth. The dough will feel sticky but that’s normal.
3. Fold in the Blueberries:
Carefully and gently fold in the fresh blueberries so they spread evenly through the dough. Be gentle so they don’t burst and dye the dough.
4. Develop Gluten with Stretch and Folds:
Every 30 minutes for 2 hours, perform four stretch-and-folds: reach under the dough, stretch it upward, and fold it over itself. This helps strengthen the dough and build structure.
5. Bulk Fermentation:
Cover your dough and let it rest at room temperature (around 70°F/21°C) for 4 to 6 hours, until it has risen and you see bubbles on the surface.
6. Shape and Proof:
Turn the dough onto a floured surface and shape it gently into a round loaf. Place it seam-side up into a floured proofing basket or bowl lined with a floured kitchen towel. Cover and refrigerate overnight (8-12 hours) for a slow proof.
7. Prepare to Bake:
Preheat your oven to 475°F (245°C) with a Dutch oven or baking stone inside. When ready, turn your dough out onto parchment paper, seam side down, and score the top with a sharp knife to allow it to expand while baking.
8. Bake the Bread:
Carefully place the dough on the parchment into the hot Dutch oven or onto the stone. Cover if using a Dutch oven. Bake for 20 minutes covered, then remove the cover and bake another 20-25 minutes until the crust is golden and crisp.
9. Cool and Enjoy:
Remove the bread from the oven and let it cool completely on a wire rack before slicing. This helps finish the cooking inside and keeps the crumb texture perfect.
Enjoy your lemony, blueberry-studded sourdough bread toasted with butter, cream cheese, or just as it is!
Can I Use Frozen Blueberries Instead of Fresh?
Yes, you can use frozen blueberries but be sure to thaw them completely and gently pat them dry to remove excess moisture. This helps prevent the dough from becoming too wet and keeps your bread from turning purple all over.
How Should I Store Leftover Lemon Blueberry Sourdough Bread?
Store leftovers in a paper bag or wrapped loosely in a kitchen towel at room temperature for up to 2 days to keep the crust crisp. For longer storage, slice and freeze the bread in an airtight container or bag for up to 3 months.
Can I Substitute Bread Flour with All-Purpose Flour?
Yes, all-purpose flour can work, but the bread will be less chewy and have a softer crumb because it has less protein. You may also need to adjust the water slightly since all-purpose flour absorbs less.
Is It Necessary to Refrigerate the Dough Overnight?
While you can bake immediately after bulk fermentation, refrigerating the dough overnight improves the flavor by allowing slow fermentation and helps develop better structure. It also makes the dough easier to handle for shaping.
