Ingredients
For the Bread
- 1½ cups all-purpose flour
- 1 teaspoon baking powder
- ½ teaspoon baking soda
- ¼ teaspoon salt
- ½ cup unsalted butter, melted and slightly cooled
- ¾ cup granulated sugar
- 2 large eggs
- ½ cup sourdough starter or discard
- ½ cup plain Greek yogurt or sour cream
- 2 tablespoons fresh lemon juice
- 1 tablespoon finely grated lemon zest
- 1 teaspoon vanilla extract
- 1 cup fresh blueberries
Optional Lemon Glaze
- 1 cup powdered sugar
- 1½–2 tablespoons fresh lemon juice
- 1 teaspoon lemon zest
Step 1: Prepare the Oven
Begin by preheating your oven to 175°C / 350°F.
Allow the oven to heat fully before putting the bread inside. A properly preheated oven helps the quick bread rise evenly.
Grease a standard 9 × 5-inch loaf pan.
You can also line the pan with parchment paper, leaving some paper hanging over the sides. This makes removing the finished bread much easier.
Step 2: Prepare the Dry Ingredients
Add the flour, baking powder, baking soda, and salt to a medium bowl.
Whisk everything together until evenly combined.
Mixing the dry ingredients first helps distribute the leavening agents throughout the flour so that the bread rises more evenly.
Set the bowl aside while you prepare the wet ingredients.
Step 3: Prepare the Lemon
Wash and dry the lemon.
Using a fine grater or zester, grate the yellow outer layer of the lemon.
Avoid grating deeply into the white part underneath because it can have a bitter taste.
Measure about 1 tablespoon of lemon zest.
Next, squeeze fresh lemon juice.
Fresh lemon juice gives the bread a much brighter flavor than bottled juice.
Step 4: Mix the Butter and Sugar
In a large mixing bowl, add the melted and slightly cooled butter.
Add the sugar and whisk until the mixture is smooth.
The butter should not be extremely hot because very hot butter can affect the eggs when they are added.
Step 5: Add the Eggs
Add the eggs one at a time.
Whisk after each addition until incorporated.
The mixture should become smooth and slightly creamy.
Add the vanilla extract and stir.
Step 6: Add the Sourdough Starter
Add the sourdough starter or discard to the wet ingredients.
Whisk gently until it is evenly incorporated.
Sourdough discard is particularly convenient for this recipe because it does not need to be at peak activity.
Its mild tang works beautifully with the sweetness of the blueberries and the brightness of lemon.
Step 7: Add Greek Yogurt
Add the Greek yogurt or sour cream.
Stir gently until combined.
The yogurt helps create a soft, moist crumb.
Avoid overmixing at this stage.
Step 8: Add Lemon
Add the fresh lemon juice and lemon zest.
Stir until everything is evenly combined.
At this point, the batter should smell wonderfully fresh and citrusy.
Step 9: Combine Wet and Dry Ingredients
Gradually add the dry ingredients to the wet mixture.
Use a spatula or wooden spoon to fold the flour into the batter.
Mix only until you no longer see large streaks of dry flour.
Do not overmix.
Overmixing can develop too much gluten and result in a heavier loaf.
A few small lumps in the batter are perfectly fine.
Step 10: Prepare the Blueberries
Add the blueberries to the batter.
If you are using fresh blueberries, gently fold them in with a spatula.
Try not to crush them.
If you are using frozen blueberries, you can add them directly while frozen. Avoid thawing them first because thawed berries can release more liquid and color into the batter.
For an extra attractive loaf, reserve a small handful of blueberries to scatter over the top.
Step 11: Transfer the Batter
Pour the batter into your prepared loaf pan.
Use a spatula to gently spread it into an even layer.
Scatter the reserved blueberries over the top.
You can also add a little extra lemon zest if desired.
Step 12: Bake
Place the loaf pan in the preheated oven.
Bake for approximately 50–65 minutes.
The exact time can vary depending on your oven and the size and material of your loaf pan.
Start checking around the 50-minute mark.
Insert a toothpick into the center of the loaf. If it comes out with a few moist crumbs but no wet batter, the bread is ready.
If the top is becoming too dark while the center still needs more time, loosely cover the loaf with aluminum foil and continue baking.
Step 13: Cool the Bread
Remove the bread from the oven and place the pan on a cooling rack.
Allow it to cool in the pan for about 10–15 minutes.
Then carefully lift the bread out using the parchment paper if you lined the pan.
Place it directly on the cooling rack.
Allow the loaf to cool completely before slicing.
This gives the crumb time to set and makes cleaner slices.
Step 14: Make the Lemon Glaze
If you want an extra lemony finish, prepare the glaze.
Add powdered sugar to a small bowl.
Add 1½ tablespoons lemon juice and whisk.
If the glaze is too thick, add a tiny amount of additional lemon juice.
If it is too thin, add a little more powdered sugar.
Stir in a small amount of lemon zest.
Step 15: Glaze the Bread
Once the bread is completely cool, drizzle the lemon glaze over the top.
You can use a spoon to create thin decorative lines across the loaf.
Allow the glaze to sit for several minutes before slicing.
The combination of sweet glaze and tangy lemon makes the blueberry bread especially delicious.
Tips for Perfect Sourdough Lemon Blueberry Bread
Don’t Overmix
Once the flour is added, mix only until combined.
Use Fresh Lemon
Fresh lemon zest and juice provide the strongest flavor.
Don’t Thaw Frozen Blueberries
If using frozen blueberries, add them directly to the batter.
Cool Completely
Cutting the bread while it is still very hot can make the slices crumbly.
Measure Flour Carefully
Too much flour can make quick bread dry. If possible, measuring flour by weight provides the most consistent results.
Variations
Lemon Raspberry Bread
Replace some or all of the blueberries with raspberries.
Lemon Poppy Seed Bread
Add 1–2 tablespoons poppy seeds to the batter.
Blueberry Cream Cheese Bread
Add small pieces of softened cream cheese to the batter for a richer variation.
Orange Blueberry Bread
Replace the lemon zest and juice with orange for a sweeter citrus flavor.
Streusel Topping
Before baking, sprinkle the top with a simple mixture of flour, sugar, butter, and cinnamon for a crumbly topping.
How to Serve
This bread is delicious sliced and served on its own.
You can also serve it with:
- Butter
- Cream cheese
- Greek yogurt
- Fresh blueberries
- Lemon curd
- A cup of tea
- Coffee
It makes a lovely breakfast, afternoon snack, or simple dessert.
How to Store
Once completely cooled, place the bread in an airtight container.
It can be kept at room temperature for a short period or refrigerated for longer storage.
If refrigerated, allow individual slices to come closer to room temperature before serving, or warm them gently.
You can also freeze the loaf.
Wrap it securely and place it in a freezer-safe container or bag. For convenience, slice it before freezing so you can thaw individual portions as needed.
Frequently Asked Questions
Can I use active sourdough starter?
Yes. Active starter can be used, although sourdough discard is convenient because this recipe does not depend on the starter for rising.
Can I use frozen blueberries?
Yes. Add them frozen rather than thawing them first.
Can I leave out the glaze?
Absolutely. The bread is delicious without the glaze. The glaze simply adds extra sweetness and lemon flavor.
Why did my blueberries sink?
Very wet or heavy blueberries can sometimes sink. Tossing them lightly with a little flour before folding them into the batter can help distribute them more evenly.
Why is my loaf dense?
Overmixing the batter or using too much flour can contribute to a dense texture. Mix gently and measure your ingredients carefully.
Final Thoughts
Sourdough Lemon Blueberry Quick Bread is a wonderful combination of tangy sourdough, bright lemon, and sweet blueberries. The loaf is soft, moist, flavorful, and easy enough for everyday baking.
It is especially useful when you have sourdough discard available and want to turn it into something delicious without making another traditional sourdough loaf.
Serve thick slices for breakfast, enjoy them with afternoon tea, or drizzle the finished loaf with lemon glaze for a simple dessert. Once you try the basic recipe, you can experiment with raspberries, poppy seeds, orange zest, streusel, or cream cheese to create your own variation.
The result is a beautifully fragrant homemade quick bread with a tender crumb, juicy berries, and plenty of fresh lemon flavor.
