How to Make Sourdough Zucchini Bread
The process of making Sourdough Zucchini Bread is straightforward, making it a perfect recipe even for novice bakers. Follow these simple steps to achieve a beautifully baked loaf.
- Preheat the Oven: Start by preheating your oven to 350°F (176°C). As it heats, you can prepare your loaf pan by lightly greasing a 9″ x 5″ loaf pan to ensure an easy release of the bread once it’s baked.
- Prepare the Zucchini: Grate 1 3/4 cups (220 g) of zucchini using the large holes of a cheese grater. Once grated, place it in a colander and squeeze out any excess moisture. This step is crucial as too much moisture can lead to a soggy loaf, robbing it of the ideal texture.
- Mix the Dry Ingredients: In a large mixing bowl, whisk together the dry ingredients: all-purpose flour, baking powder, baking soda, fine sea salt, ground cinnamon, and chopped walnuts. This blends everything evenly and ensures that the leavening agents are well distributed.
- Combine the Wet Ingredients: In a separate bowl, mix together the wet ingredients: light brown sugar, large eggs, sourdough starter discard, vanilla extract, and avocado oil. Whisk these ingredients until smooth. The sugar and eggs should be well combined, creating a rich batter.
- Combine Wet and Dry Mixtures: Pour the wet mixture into the bowl containing the dry ingredients. Gently fold them together using a spatula. Be careful not to overmix; just stir until the ingredients are combined.
- Incorporate Zucchini: Finally, fold in the prepared zucchini until evenly distributed throughout the batter.
- Pour and Bake: Transfer the batter to the prepared loaf pan, smoothing the top with a spatula if necessary. Place it in the preheated oven and bake for 55-60 minutes. You’ll know it’s done when a toothpick inserted into the center of the bread comes out clean.
- Cool: Once baked, remove the pan from the oven and let it cool for about 10-15 minutes. After this, carefully transfer the bread to a cooling rack to cool completely before slicing.
This step-by-step guide ensures you achieve the perfect Sourdough Zucchini Bread that will impress everyone around you.

Expert Tips for Sourdough Zucchini Bread
Baking is both an art and a science, and having a few expert tips up your sleeve can make a world of difference in the outcome of your Sourdough Zucchini Bread:
- Zucchini Preparation: Be diligent in squeezing out excess moisture from the grated zucchini. Too much moisture can lead to a dense loaf that does not rise properly, altering the intended texture.
- Check for Doneness: While baking, keep an eye on the bread as oven temperatures can vary. A toothpick inserted into the center should come out clean when the bread is fully baked.
- Toast for Optimal Flavor: Toasting a slice before serving can enhance the flavor, bringing out the warm spices and creating a delightful texture contrast.
- Experiment Side Add-ins: Feel free to get creative! You can incorporate other ingredients like chocolate chips, raisins, or seeds to add more flavor and texture to the bread.
- Cooling is Key: Allow the bread to cool thoroughly before slicing. This step helps the flavors to settle and enhances the overall structure of the bread, making for cleaner slices.
By following these expert tips, you ensure that each loaf of Sourdough Zucchini Bread you bake is not only delicious but also perfectly textured.
How to Store Sourdough Zucchini Bread
Proper storage will help maintain the freshness of your Sourdough Zucchini Bread. Here’s how you can store it effectively:
- Room Temperature: If you plan to consume the bread within a few days, simply wrap it in plastic wrap or place it in an airtight container and store it at room temperature. This will keep it moist without drying it out.
- Refrigeration: To extend the shelf life to about a week, store the bread in the refrigerator. It’s best to wrap it tightly to prevent it from absorbing odors from other foods.
- Freezing: If you want to keep it for an extended period, freezing is your best option. Slice the bread and individually wrap each slice in plastic wrap, then place them in a freezer-safe bag. This way, you can enjoy a piece whenever you desire without needing to defrost the entire loaf.
By following these storage tips, you can savor your Sourdough Zucchini Bread for days or even weeks after baking it.
Variations of Sourdough Zucchini Bread
Once you’ve mastered the classic Sourdough Zucchini Bread, why not experiment with some fun variations?
- Chocolate Chip Zucchini Bread: Add a cup of semi-sweet chocolate chips to the batter for a decadent treat. The sweetness of the chocolate contrasts beautifully with the spiced zucchini bread.
- Nut-Free Option: If you have allergies or prefer a nut-free loaf, simply omit the walnuts. You can substitute with sunflower seeds for a delightful crunch.
- Herb-Infused Bread: Make a savory version by adding fresh herbs like rosemary, thyme, or basil to the batter. These additions lend a sophisticated flavor that can complement your meals.
- Fruit-Infused Bread: Incorporate fruits like raspberries or cranberries to add a new dimension of flavor. This helps to give the bread a slight tartness that pairs well with the sweetness of zucchini.
Through these variations, you can continually enjoy Sourdough Zucchini Bread while keeping things fresh and exciting.
