This sweet sourdough bread recipe combines a tender, tangy crumb with juicy blueberries and bright lemon zest for a loaf that is as beautiful as it is delicious. Perfect for weekend baking, brunch spreads, or using up your sourdough discard.

If you have ever stared at a jar of sourdough discard and wondered whether it could become something truly special, this is your answer. This blueberry lemon sourdough bread sits right at the intersection of a classic quick bread and a sourdough loaf. It is tender, fragrant, dotted with jammy berries, and finished with a crackly sugar crust that practically begs to be photographed.
Whether you are new to sourdough inclusions or a seasoned baker looking for a creative way to use your discard, this sweet sourdough bread recipe delivers every single time. No long ferment. No fussy shaping. Just a stunning, bakery-worthy loaf that comes together in under an hour of active time.
The magic here is the sourdough discard. Unlike an active starter used for fermented loaves, discard adds a gentle, almost creamy tang that deepens the flavor without making the bread sour. Paired with bright lemon zest and sweet-tart blueberries, that subtle acidity lifts the whole loaf and keeps every bite interesting.
This is not your typical berry bread. It is closer in spirit to a blueberry cheesecake sourdough bread than a standard muffin loaf. The crumb is soft and slightly dense in the best possible way, the lemon is unmistakably present, and those blueberries burst into little pockets of juice as the loaf bakes.
Chef's Tip: Toss your blueberries in a teaspoon of flour before folding them into the batter. This simple step keeps them suspended throughout the loaf rather than sinking to the bottom during baking.
Getting the most out of this berry sourdough bread really does come down to a few key details. A quality microplane zester pulls the fragrant oils from the lemon peel without any bitter pith, and a well-fitted 9x5 loaf pan ensures the bread bakes evenly with a beautiful domed top.
One of the things that makes this recipe so fun is how easily it adapts to different sourdough loaf flavors. The base batter is essentially a canvas.
All of these easy sourdough inclusions require zero changes to the base recipe. That kind of flexibility is exactly what you want on a weekend morning when inspiration strikes.
Baker's Note: If your sourdough discard has been sitting in the fridge for more than a week, give it a quick smell before using. It should smell pleasantly sour and yeasty. If it smells off or has any pink or orange streaks, discard it and start fresh.
Overmixing is the number one enemy of a tender quick bread. Once your wet and dry ingredients come together, stop stirring. A few visible streaks of flour in the batter are completely fine and will disappear as the loaf bakes. The blueberries should be folded in with just three or four gentle turns of the spatula.
Also, do not skip the coarse sugar topping. That sparkly, slightly crunchy crust is what separates a homemade loaf from a bakery-level one.

This sweet sourdough bread recipe combines a tender, tangy crumb with juicy blueberries and bright lemon zest for a loaf that is as beautiful as it is delicious. Perfect for weekend baking, brunch spreads, or using up your sourdough discard.
Preheat your oven to 350 degrees F (175 degrees C). Grease a 9x5 inch loaf pan and line it with a strip of parchment paper, leaving overhang on the two long sides for easy lifting.
In a large bowl, whisk together the flour, baking soda, baking powder, salt, and granulated sugar until well combined. Set aside.
In a separate medium bowl, whisk together the sourdough starter or discard, eggs, melted butter, milk, vanilla extract, lemon zest, and lemon juice until smooth.
Pour the wet ingredients into the dry ingredients and fold gently with a spatula until just combined. Do not overmix. A few streaks of flour are fine at this stage.
Toss the blueberries with 1 teaspoon of flour (this prevents them from sinking), then gently fold them into the batter with just 3 to 4 strokes.
Pour the batter into the prepared loaf pan and smooth the top. Sprinkle generously with coarse sugar.
Bake for 50 to 60 minutes, or until a toothpick inserted into the center comes out clean and the top is deep golden brown. If the top is browning too quickly after 35 minutes, tent loosely with foil.
Allow the loaf to cool in the pan for 15 minutes before lifting out using the parchment overhang. Transfer to a wire rack and cool for at least 20 minutes before slicing.
This loaf is genuinely at its best the day after baking, once the lemon has had time to settle into every slice. Serve it at room temperature with softened salted butter, a smear of whipped ricotta, or a drizzle of local honey.
For sourdough discard blueberry lemon loaf leftovers, wrap the cut side tightly with plastic wrap and store at room temperature for up to three days. Freeze individual slices between sheets of parchment for up to two months, and reheat straight from frozen in a toaster oven for an almost-fresh result every time.
