Sourdough Zucchini Bread
This Sourdough Zucchini Bread combines tangy sourdough discard with fresh shredded zucchini for a wonderfully moist, tender quick bread that's perfect for brunch or an afternoon snack.
A Loaf Bread Soft Enough to Fall in Love With
If you have a jar of sourdough discard sitting in your fridge and a zucchini or two from the garden, this Sourdough Zucchini Bread Recipe is exactly what your kitchen needs. It is one of those loaf recipes that turns two humble ingredients into something genuinely special. The tang from the sourdough discard balances the sweetness of the bread, while the shredded zucchini keeps every slice unbelievably moist. This is not a dense, gummy quick bread. It is a soft, tender, lightly spiced loaf that tastes like a warm hug on a plate.
This recipe has become a staple in my house any time I am doing a round of sourdough baking. Rather than tossing the discard, I fold it right into this batter, and the payoff is a bread soft enough to eat plain, yet sturdy enough to hold a smear of butter or cream cheese without falling apart.
Before we get cooking, the right tools and ingredients make a real difference here. A sturdy box grater makes quick work of the zucchini, a good loaf pan ensures even baking, and using fresh baking soda and baking powder keeps the crumb light instead of gummy. These are the products that genuinely help this recipe shine:
Why Sourdough Discard Works So Well Here
Sourdough discard is often treated like a byproduct, but in baked goods like this one, it is a secret weapon. It adds a gentle tang that plays beautifully against the natural sweetness of zucchini and brown sugar. It also contributes extra moisture and a slightly chewy, tender crumb that regular quick breads sometimes lack.
You do not need an active, bubbly starter for this recipe. Discard straight from the fridge, even if it looks a little flat or separated, works perfectly. This makes it an ideal recipe for anyone new to sourdough baking who wants to reduce waste without committing to a whole sourdough loaf.
Chef's Tip: Always squeeze your shredded zucchini in a clean towel before adding it to the batter. Skipping this step is the number one reason quick breads turn out soggy in the middle.
The Secret to a Perfectly Moist Crumb
The combination of oil, eggs, and zucchini is what gives this loaf its signature softness. Unlike butter, oil keeps the crumb tender even after the bread cools completely, which means this loaf stays soft for days rather than drying out by the next morning.
A touch of cinnamon warms up the flavor without overpowering the zucchini, and the mix of granulated and brown sugar adds both sweetness and a subtle molasses depth. If you love a bit of crunch, folding in chopped walnuts adds texture and a nutty contrast to the soft interior.
This loaf is incredibly versatile too. Serve a slice with your morning coffee, pack it into lunchboxes, or set it out as part of a brunch bread spread alongside oatmeal breakfast bars and fresh fruit. It holds up well next to both sweet and savory brunch dishes, making it an easy centerpiece for a relaxed weekend table.

Sourdough Zucchini Bread
This Sourdough Zucchini Bread combines tangy sourdough discard with fresh shredded zucchini for a wonderfully moist, tender quick bread that's perfect for brunch or an afternoon snack.
Ingredients
- 1 3/4 cups all-purpose flour, spooned and leveled
- 1 cup sourdough discard, unfed, straight from the fridge is fine
- 1 1/2 cups zucchini, shredded, excess moisture squeezed out
- 3/4 cup granulated sugar
- 1/4 cup brown sugar, packed
- 1/2 cup vegetable oil, or melted coconut oil
- 2 large eggs, room temperature
- 1 tsp vanilla extract
- 1 tsp ground cinnamon
- 1 tsp baking soda
- 1/2 tsp baking powder
- 1/2 tsp salt, fine sea salt
- 1/2 cup walnuts, chopped, optional
Instruction
Preheat the oven to 350 degrees F (175 degrees C). Grease a 9x5-inch loaf pan and line it with parchment paper, leaving an overhang on the long sides.
In a large bowl, whisk together the sourdough discard, granulated sugar, brown sugar, oil, eggs, and vanilla extract until smooth and well combined.
Fold the shredded zucchini into the wet mixture.
In a separate bowl, whisk together the flour, cinnamon, baking soda, baking powder, and salt.
Add the dry ingredients to the wet ingredients and gently fold together with a spatula until just combined. Do not overmix.
Fold in the chopped walnuts, if using, reserving a small handful to sprinkle on top.
Pour the batter into the prepared loaf pan, smoothing the top with a spatula. Sprinkle the reserved walnuts over the surface.
Bake for 55 to 65 minutes, until a toothpick inserted into the center comes out clean or with a few moist crumbs.
Let the bread cool in the pan for 15 minutes, then use the parchment overhang to lift it out onto a wire rack to cool completely before slicing.
Equipment
- 9x5-inch loaf pan
- Parchment paper
- Large mixing bowl
- Box grater

Notes
How To Store Bread Like This the Right Way
Proper storage keeps this loaf tasting fresh for as long as possible. Once the bread has cooled completely, wrap it tightly in plastic wrap or store it in an airtight container at room temperature. It will stay soft and delicious for about 3 days on the counter.
For longer storage, this bread freezes exceptionally well. Slice it first, then wrap individual pieces in plastic wrap and place them in a freezer bag. That way you can pull out a single slice whenever a craving hits, no thawing the whole loaf required.
Chef's Tip: If your bread has been in the fridge and firmed up, a quick 10 to 15 second zap in the microwave brings back that just-baked softness.
Variations Worth Trying
This recipe is easy to make your own. A few ideas to switch things up:
- Add mix-ins: Chocolate chips, dried cranberries, or shredded coconut all work beautifully folded into the batter.
- Make it a spice loaf: Add a pinch of nutmeg or ground ginger alongside the cinnamon for a cozier, spiced flavor.
- Turn it into muffins: Divide the batter into a lined muffin tin and bake for 20 to 25 minutes for individual portions, perfect for busy mornings.
However you choose to make it, this Sourdough Zucchini Bread is proof that a little discard and a bit of garden zucchini can turn into one of the best loaf recipes in your rotation.
