Ingredients You’ll Use

• 2 cups all-purpose flour
• 2 teaspoons baking powder
• ½ teaspoon table salt or fine sea salt
• 2 large eggs
• 1 cup granulated sugar
• ½ cup canola or vegetable oil
• ½ cup buttermilk
• zest of 1 lemon
• 2 tablespoons fresh lemon juice (about 1 large lemon)
• 1 cup shredded zucchini
• 1 cup powdered sugar
• juice of 1 lemon

How to Make the Bread

1. Preheat oven to 350°F and grease four mini loaf pans (6″ x 3½”) or one 9″ x 5″ loaf pan with cooking spray.
2. Whisk together 2 cups all-purpose flour, 2 teaspoons baking powder, and ½ teaspoon salt in a small bowl.
3. Wash and shred 1 cup zucchini with a box grater (peel most skin if desired); lightly pat shredded zucchini dry if very watery.
4. Zest 1 lemon and squeeze about 2 tablespoons fresh lemon juice (about 1 large lemon).
5. In a large bowl or stand mixer, beat 2 large eggs on medium-high for ~30 seconds.
6. Add 1 cup granulated sugar and ½ cup canola or vegetable oil to the eggs and beat on medium 1–2 minutes until smooth and lighter in color.
7. Pour in ½ cup buttermilk, lemon zest, and lemon juice; mix just until combined.

8. Slowly add the dry ingredients and the shredded zucchini to the wet mixture; mix on low or fold by hand until just combined and no flour streaks remain.
9. Divide batter evenly among prepared pans or pour into the large loaf pan.
10. Bake mini loaves 30–34 minutes or a large loaf 45–50 minutes at 350°F, until the top is set, springs back when pressed, and a toothpick comes out clean or with moist crumbs.
11. Cool the loaves in the pans about 15 minutes, then remove and transfer to a wire rack to cool completely.
12. Whisk 1 cup powdered sugar with the juice of 1 lemon in a small bowl until smooth and pourable, adding more juice to thin or more powdered sugar to thicken as needed.
13. Drizzle or pipe the glaze over completely cooled loaves.

Tips for Perfect Results

1. Use Fresh Lemons : Fresh squeezed lemon juice is totally worth the little extra effort — it brings a brightness bottled lemon juice just can’t match. I’ve heard from a few readers who liked bottled juice fine, so if that’s what you have, it will still work. But fresh will make your lemon zucchini bread taste more vibrant and fresh. You’ll need about two large lemons.
2. No Substitutes for Buttermilk : If you don’t have buttermilk, making your own with white vinegar and milk works well (1/2 tablespoon vinegar + 1/2 cup milk, let sit 5 minutes). However, I recommend using real buttermilk from the store whenever you can — it gives the best texture and flavor.
3. Lemon Glaze : For a less intense lemon pop, try using milk instead of lemon juice in the glaze. Also, wait to glaze your loaves until they’re completely cool — if they’re warm, the glaze will just melt away and won’t create those pretty drizzles.
4. Pan Size : I prefer mini loaf pans for this recipe because the bread bakes more evenly and portion sizes are perfect for sharing. One large loaf pan works too, but mini loaves freeze great and make lovely gifts for neighbors or friends!
5. Lemon Zest : Only zest the bright yellow outer layer of the lemon. Avoid going too deep into the white pith — it’s bitter and can harshen the flavor of your bread.
6. Peeling Zucchini : You don’t have to peel your zucchini, but I like to peel most of the skin off with a vegetable peeler for a smoother texture. It’s totally up to you.
7. Managing Moisture : Some zucchinis hold a lot of water. If yours seems really wet after shredding, lightly blot it with paper towels to soak up the excess moisture. You don’t want the batter soupy but it’s okay if the zucchini isn’t bone dry.

Add-Ins and Flavor Twists

• Lemon-Poppy Seed: Stir 1–2 tablespoons of poppy seeds into the batter for a classic, crunchy twist that pairs perfectly with lemon.
• Blueberry-Zucchini: Fold in ¾ to 1 cup fresh or frozen blueberries. If using frozen, toss them lightly in flour first to keep them from sinking.
• Nutty Add-In: Add ½ cup chopped walnuts or pecans for some satisfying crunch and nutty flavor.
• Streusel Topping: Sprinkle a cinnamon-sugar-oat streusel on top before baking to add a sweet, crunchy finish.
• Cream Cheese Glaze: Swap the lemon powder sugar glaze for a cream cheese glaze made with softened cream cheese, powdered sugar, and a tiny splash of lemon juice or milk.
• Muffin or Large Loaf: You can also fill a 12-cup muffin pan (bake 16–20 minutes) with the batter or use one 9×5” loaf pan (bake 45–50 minutes).
• Buttermilk Substitute: No buttermilk? No problem! Mix ½ tablespoon white vinegar into ½ cup milk and let it sit 5 minutes for a quick stand-in.
• Milder Lemon Flavor: Use milk instead of lemon juice in the glaze for a softer, less zesty finish.

Storage and Freezing Tips

• Room Temperature : Keep leftover lemon zucchini bread at room temperature in a tightly sealed container, wrapped in plastic wrap, or covered with foil for up to 3-4 days.
• Refrigerator : For longer storage, place the bread in the fridge for up to one week, making sure it’s wrapped well or stored in an airtight container to keep it fresh.
• Freezer Storage : You can freeze baked and cooled bread (unglazed) for 2-3 months. Wrap the loaf tightly in plastic wrap, then again in foil to prevent freezer burn. For extra protection, place it in a freezer-safe bag or container. When ready to enjoy, thaw overnight in the fridge and then add the glaze right before serving.

Common Questions and Answers

• Can I leave the zucchini skin on? : Yes! You can shred zucchini with the peel on or off. I prefer peeling mine, but both options work well. Just wash the zucchini thoroughly before shredding either way.
• How do I prevent watery batter from shredded zucchini? : If your shredded zucchini looks very wet, gently pat it with paper towels to remove some moisture. It doesn’t need to be perfectly dry, but excess water can make the bread soggy, so this step helps keep your lemon zucchini bread tender but not wet.
• Can I use bottled lemon juice? : You can, and the bread will still turn out fine, but fresh lemon juice and zest make the bread taste brighter and fresher. I recommend fresh whenever possible.
• How can I tell when the bread is done? : The top should look set and spring back when lightly pressed. When you insert a toothpick in the center, it should come out clean or with moist crumbs, but not wet batter.
• What are the baking times for different pan sizes? : If baking four mini loaf pans (6″ x 3½”), bake 30–34 minutes. For one large 9″ x 5″ loaf pan, bake 45–50 minutes. If you bake muffins, expect 16–20 minutes.
• Can I freeze the bread? : Absolutely! Freeze baked, cooled, and unglazed loaves for 2–3 months. Wrap tightly in plastic and foil or place in a freezer bag. Thaw in the fridge overnight and add glaze before serving.
• How should I store leftovers? : Store lemon zucchini bread at room temperature well wrapped or in an airtight container for 3–4 days, or refrigerate for up to one week.
• Can I substitute the oil or use whole wheat flour? : The recipe calls for vegetable or canola oil, which give the best moist texture. Melted butter might work but could change the flavor and texture. I don’t recommend whole wheat flours here because they make the bread more dense and less tender.
