Ingredients
- 1 cup sourdough discard (unfed or active, at room temperature)
- 1 1/2 cups all-purpose flour
- 1 teaspoon baking powder
- 1/2 teaspoon baking soda
- 1/4 teaspoon salt
- 1/2 cup granulated sugar
- 1/4 cup vegetable oil or melted unsalted butter
- 2 large eggs
- 1/4 cup fresh lemon juice (about 1-2 lemons)
Zest of 1 lemon
1 cup grated zucchini (excess moisture squeezed out)
1 teaspoon vanilla extract (optional)
Instructions
- Preheat your oven to 350°F (175°C). Grease a standard 9×5-inch loaf pan or line it with parchment paper for easy removal.
- In a large mixing bowl, whisk together the sourdough discard, sugar, and eggs until well combined. Add the vegetable oil and lemon juice, stirring until smooth. Mix in the lemon zest and vanilla extract if using.
- In a separate bowl, whisk together the flour, baking powder, baking soda, and salt. Gradually add the dry ingredients to the wet mixture, stirring gently until just combined. Do not overmix to keep the loaf light.
- Fold in the grated zucchini, ensuring even distribution throughout the batter. Be careful not to add excess moisture; squeeze out as much water as possible from the zucchini before folding in.
- Pour the batter into the prepared loaf pan, smoothing the top with a spatula. Tap the pan lightly on the counter to remove air bubbles.
- Bake in the preheated oven for 50-60 minutes, or until a toothpick inserted into the center comes out clean. If the top browns too quickly, tent loosely with aluminum foil halfway through baking.
- Remove from oven and let cool in the pan for about 10 minutes. Then transfer the loaf to a wire rack to cool completely before slicing.
Tips
- For a gluten-free version, substitute the all-purpose flour with a 1:1 gluten-free baking flour blend.
- To enhance lemon flavor, add a little lemon extract or more lemon zest.
- Ensure zucchini is well-drained to prevent the batter from becoming too watery, which can affect baking time and loaf texture.
- Use fresh lemon juice for the best flavor; bottled lemon juice can be used in a pinch but may lack brightness.
Serving Suggestions
This zucchini lemon loaf is perfect served plain or with a light dusting of powdered sugar. It pairs wonderfully with a cup of tea or coffee and makes an excellent breakfast or afternoon snack. For added indulgence, spread with a thin layer of cream cheese or lemon glaze.

Storage and Reheating
Store the cooled loaf in an airtight container at room temperature for up to 2 days. For longer storage, wrap tightly in plastic wrap or foil and refrigerate for up to 5 days. To enjoy later, reheat slices in the microwave for 10-15 seconds or in a 350°F (175°C) oven for about 10 minutes. The loaf can also be frozen for up to 3 months; slice beforehand for easy thawing.
Frequently Asked Questions
Can I use unfed sourdough discard for this recipe?
Yes, unfed sourdough discard works well and adds a mild tang to the loaf. It’s a great way to use up discard that isn’t active or bubbly.
Do I need to squeeze out moisture from the zucchini?
Absolutely. Excess moisture can make the batter too runny, affecting baking time and the loaf’s texture. Use a clean kitchen towel or cheesecloth to squeeze out as much water as possible before folding in.
Can I make this loaf dairy-free?
Yes, substitute the butter or oil with a neutral oil like coconut or vegetable oil. If adding eggs, you can replace them with flax eggs or commercial egg replacers. The loaf will still turn out moist and flavorful.
What can I do if the loaf sinks in the middle?
This can happen if the batter is overmixed or if the oven temperature is too high. Make sure to mix gently and bake at the correct temperature. Also, avoid opening the oven door during the first 30 minutes of baking to prevent sudden temperature drops.
Is this recipe suitable for gluten-free baking?
Yes, by replacing the all-purpose flour with a gluten-free baking blend and adding xanthan gum if necessary, you can enjoy a gluten-free version of this delightful loaf.
How can I tell when the loaf is done?
Insert a toothpick into the center; if it comes out clean or with just a few moist crumbs, the loaf is ready. Also, the top should be golden brown, and the edges slightly pull away from the pan.
By incorporating your sourdough discard into this zucchini lemon loaf, you create a flavorful, moist bread that reduces waste and delights the palate. Whether you’re a sourdough enthusiast or just looking for a new way to enjoy zucchini, this loaf is a versatile and satisfying choice that’s sure to become a favorite.
