Sourdough Discard Lemon Blueberry Quick Bread

Sourdough discard lemon blueberry quick bread is one of those recipes I wish I’d discovered years ago. I had a jar of discard sitting in the fridge after a busy week of baking with Isabella and Emma, and honestly, I almost tossed it. But then I grabbed a handful of fresh blueberries, a couple of lemons, and decided to throw together a quick bread. The result? A soft, tangy, berry-studded loaf that Henry asked me to make again the very next day. If you love lemon blueberry quick bread but want something with a little more depth and flavor, this sourdough discard baking recipe is going to blow your mind. Plus, if you’re into easy baking with simple ingredients, you’ll also love my greek yogurt banana bread recipe for another no-fuss loaf.

Wet ingredients:

• 1 cup (227g) sourdough starter discard (or active starter)

• 2 large eggs
• 2 tablespoons fresh lemon juice
• ¼ cup milk

How to Make Sourdough Discard Lemon Blueberry Quick Bread

Quick bread version

1. Preheat your oven to 350°F (175°C). Lightly grease a 9×5 loaf pan with butter or line it with parchment paper.
2. In a large bowl, whisk together the flour, baking powder, baking soda, salt, and lemon zest.
3. In another bowl, combine the sourdough starter, brown sugar, melted butter, eggs, milk, and lemon juice. Mix until well combined.
4. Add the wet ingredients to the dry and stir until just combined. Do NOT overmix. (A few lumps are totally fine trust me on this one.)
5. Gently fold in the blueberries.
6. Pour the batter into your prepared pan and bake for 55 to 65 minutes, or until a toothpick inserted in the center comes out clean. If the top browns too fast, tent it loosely with aluminum foil.
7. Cool in the pan for 10 minutes, then transfer to a wire rack to cool completely.
8. Mix the glaze ingredients in a small bowl and drizzle over the cooled loaf.
9. Slice and enjoy your homemade sourdough discard sweet bread!

Long fermented version

Want even more tang and better digestibility? Start the batter 16 to 18 hours before you plan to bake.

Follow steps 2 through 5 above, then cover the bowl with a damp towel or plastic wrap. Let it rise for 4 to 6 hours at room temperature, then pop it in the fridge overnight (about 12 hours).

The next morning, give the dough a few good stirs with a wooden spoon. Pour it into the greased pan and bake at 350°F for 55 to 65 minutes. Cool, glaze, and serve at room temperature.

Storage and Reheating Tips

This loaf keeps beautifully on the counter for 2 to 3 days when wrapped in plastic wrap or stored in an airtight container. It’ll last up to a week in the fridge.

For longer storage, freeze individual slices wrapped in plastic. Thaw at room temperature or pop them in a toaster oven for a warm treat. The flavors actually get better the next day as the lemon and sourdough mellow together.

Tasty Variations for Your Sourdough Discard Bread

Have you ever tried swapping the berries? Here are some fun twists:

• Raspberries: Swap them 1:1 for blueberries for a slightly tarter bread.
• Orange zest instead of lemon: For a blueberry orange version that’s just as good.
• Add a crumb topping: Mix butter, flour, and sugar for a streusel layer before baking.
• Chocolate chips: Because… why not? A handful of white chocolate chips pairs beautifully with the lemon.

Pro tip: If you’re using frozen blueberries, toss them in a tablespoon of flour before folding them in. This keeps them from bleeding too much color into the batter.
