Recipe highlights
- great use for your discard: We love having recipes to utilize sourdough discard. It cuts down on food waste and lends another layer of flavor to the bread.
- sneak some veggies into the diet: Let's face it, this is a fabulous and delicious way to get the family to eat more veggies!
- breakfast, snack or dessert: This lightly sweetened quick bread can be enjoyed morning, noon or night.
What you'll need
- fresh zucchini: Because the moisture in each zucchini varies so much, we developed this recipe with grated zucchini that has had as much moisture removed as possible. This will help to produce consistent results every time you bake this quick bread.
- light brown sugar, eggs, sourdough starter, vanilla extract, oil: One of the great things about this recipe is that you don't have to use an electric mixer. The ingredients are easy to mix with a spatula.
- flour, baking soda, baking powder, salt, cinnamon, chopped walnuts: The dry ingredients are whisked together in a separate bowl to make it easier to incorporate them into the wet ingredients, without over-mixing.
Step by step instructions
Step 1: Preheat your oven to 350°F (176°C) and lightly grease a 9" x 5" baking pan.
Step 2: Grate the zucchini and squeeze it to release any extra moisture. Leave the zucchini in a colander while you mix the remaining ingredients.
Step 3: Mix the dry ingredients together in a small bowl and set aside.
Step 4: In a large mixing bowl, combine the wet ingredients and stir until the mixture is smooth. Add the dry ingredients to the wet ingredients and stir until combined. Give the zucchini one last squeeze and stir it into the batter.
Step 5: Pour the batter into a greased 9” x 5” baking dish and bake at 350°F for 55-60 minutes or until a toothpick inserted into the center comes out clean.
Step 6: Let the zucchini bread cool for 15 minutes. Run a butter knife around the edges to release them from the dish and transfer the bread to a cooling rack.
Enjoy warm or at room temperature.

Hi Jocelyn, I've never tried it but I definitely think it would work!

Does does sourdough discard need feeding before adding to ingredients? And can vegan eggs be substituted?
Amy Duska says
Hi Eve, no this recipe uses unfed starter. I have not used vegan egg replacement in this recipe but I think it would work.
