This Lemon Blueberry Sourdough Bread is crusty on the outside, soft and chewy on the inside, and packed with juicy blueberry pockets and fresh lemon zest. It’s the kind of loaf that feels special, but it’s still totally doable at home—especially if you already have a bubbly starter. The bright lemon flavor makes it feel like spring in bread form, and the blueberries give you those sweet little pops in every slice.
The Sourdough Loaf You’ll Want All Spring
If you love classic artisan sourdough but want something a little more fun, this Lemon Blueberry Sourdough Bread is it. It’s a cozy baking project (with an overnight cold proof) that tastes like a bakery treat when it’s toasted.
The standout technique here is laminating the inclusions (spreading blueberries and zest into a thin sheet of dough, then folding). It helps you get pretty, even distribution without smashing all the berries. Everyone asks for this loaf—especially once they see those purple-blue swirls and sunny lemon specks.

Ingredients for Lemon Blueberry Sourdough Bread
For the Dough
- Bread flour (about 4 cups + 2 tablespoons, spooned and leveled): Gives the dough strength so it can rise high and hold the blueberries. You can use all-purpose flour, but the loaf may be slightly softer and spread more.
- Water (11 3/4 fluid ounces): Hydrates the dough for that airy crumb. If your kitchen is very dry, you may need a tiny splash more.
- Active sourdough starter (about 1 3/4 ounces, bubbly and at peak): The natural leavener that gives you rise and that classic sourdough flavor. If your starter is sleepy, feed it and wait until it doubles and looks domed.
- Fine sea salt (2 teaspoons): Brings out flavor and strengthens the dough. If using kosher salt, you may need a little more.
Inclusions
- Fresh blueberries (1 cup): Sweet pops and gorgeous color. Frozen works, but don’t thaw—use straight from the freezer and handle gently to avoid purple streaks.
- Lemon zest (zest of 1 large lemon, about 1 tablespoon): Adds bright, citrusy flavor without adding extra liquid. Only zest the yellow part (the white can be bitter).
Optional Whipped Blueberry Honey Butter
- Unsalted butter (8 tablespoons, room temperature): Makes a fluffy, spreadable topping.
- Fresh blueberries (1/2 cup, mashed): Adds natural color and fruity flavor.
- Honey (2 tablespoons): Light sweetness that pairs perfectly with lemon and blueberry.
- Pinch of salt: Keeps it from tasting flat.
How to Make Lemon Blueberry Sourdough Bread
- 1. Feed your starter so it’s bubbly and at peak. Depending on your room temperature, this usually takes 4–12 hours after feeding. You want it domed on top and full of bubbles.
- 2. Mix the dough: Stir the starter into the water until it looks milky. Add flour and salt and mix until no dry flour remains. The dough will look shaggy. Rest 30 minutes.
- 3. Stretch and fold: Do a set of stretch-and-folds (pull up one side of dough, fold over, rotate bowl, repeat 4 times). Rest 30–60 minutes, then repeat until you’ve done 4 total sets. The dough should look smoother and stronger.
- 4. Bulk ferment: Let the dough rise until it increases in size by about 50% and looks airy and jiggly. In a cooler home (around 68–70°F), this often takes 6–9 hours, but go by the dough cues.
- 5. Pre-shape: Gently turn the dough onto the counter and shape into a loose round. Cover and rest 30 minutes.
- 6. Laminate the blueberries and lemon: Stretch dough into a large rectangle. Sprinkle half the blueberries and zest, fold the left side in, sprinkle half of what’s left, fold the right side over, sprinkle the rest, then roll up. Shape into a round. A few blueberries may peek through—totally fine.
- 7. Cold proof: Place seam-side up in a floured banneton (or towel-lined bowl). Cover and refrigerate for 8–24 hours.
- 8. Bake: About 30 minutes before baking, pop the dough in the freezer for easier scoring. Preheat a Dutch oven in a 450°F oven for at least 30 minutes. Flip dough onto parchment, score, bake covered 27 minutes, then uncovered 10–15 minutes until deep golden. Cool at least 1 hour before slicing.
Optional: Whipped Blueberry Honey Butter
Beat room-temperature butter with mashed blueberries, honey, and a pinch of salt for 2–3 minutes until fluffy. Spread on toasted slices.
Tips for Perfect Lemon Blueberry Sourdough Bread
- Use a strong flour: Bread flour helps the dough hold the fruit without collapsing.
- Zest smart: Only zest the yellow part of the peel for bright flavor (avoid the bitter white).
- Handle blueberries gently: Pressing too hard can make the dough streak purple and get sticky.
- Look for dough cues: Bulk ferment is done when the dough is airy, jiggly, and bubbly.
- Preheat the Dutch oven: A fully hot pot is what gives you that bakery-style spring.
- Cool before slicing: Waiting keeps the crumb set and sliceable.
Variations & Substitutions
- Mixed berry loaf: Use half blueberries and half raspberries.
- Orange swap: Use orange zest instead of lemon for a softer citrus flavor.
- Add crunch: Fold in 1/3 cup chopped toasted almonds with the berries.
- Make it extra cozy: Add 1/2 teaspoon ground cinnamon to the dough.
- Frozen berry option: Use frozen berries straight from the freezer and handle gently.
Make-Ahead, Storing & Reheating
- Room temperature: Keep in a bread box or paper bag for 2 days.
- Freeze: Slice and freeze up to 2 months. Toast straight from frozen.
- Refresh: Toast slices and top with butter, honey, jam, or whipped blueberry honey butter.
Serving Suggestions & Pairings
- Breakfast: Toasted slice + butter + drizzle of honey.
- Brunch: Serve with yogurt, fruit, and eggs.
- Snack: Warm slice with tea or coffee.
- Dessert-y treat: Top with whipped cream cheese and extra zest.
