A loaf of Lemon Zucchini Bread topped with white icing, garnished with four lemon slices and two sprigs of fresh mint, displayed on a white tray.

I made one large loaf, but if you prefer, you can make two smaller loaves. Enjoy one now and freeze the other for later. It’s perfect for breakfast, brunch, afternoon coffee, or an easy homemade gift.

Unlike many quick bread recipes, this one stays moist for several days thanks to the zucchini. It actually tastes even better the next day after the lemon flavor has had time to develop.

Time needed: 1 hour and 30 minutes

Preheat the oven to 350°F. Prepare one or two loaf pans with Wilton cake release. Coat them all the way to the top of the pan.
Mix together the oil, Greek yogurt, lemon juice, and lemon sugar until smooth.
Beat in the eggs one at a time. Whisk together the flour, baking soda, baking powder, and salt in a medium bowl before adding them to the wet ingredients.
Fold in the grated zucchini and vanilla just until combined.
Pour the batter into your prepared pan or divide it evenly between the two pans.
Bake for 55 to 65 minutes or until a toothpick inserted into the center comes out clean. Cool for 10 to 20 minutes before removing from the pans.
Whisk together the powdered sugar and lemon juice, then drizzle over the loaf. Garnish with fresh lemon zest, lemon rounds, or lemon spirals, if desired.

Tips for the Best Lemon Zucchini Bread

Leave the peel on the zucchini for extra color and nutrition.
Do not squeeze the moisture from the zucchini unless it’s extremely wet.
Mix the batter only until combined to keep the bread tender.
Fresh lemons provide the best flavor.
Let the glaze set before slicing for cleaner pieces.

Should You Peel Zucchini?

No. The peel becomes soft while baking and adds color, fiber, and nutrients. Simply wash the zucchini well before grating.

Do I Need to Remove Moisture from the Zucchini?

Usually, no.

Fresh zucchini naturally provides moisture that keeps quick breads soft. If your zucchini seems unusually watery, lightly blot it with paper towels before adding it to the batter.

Storage

Store covered at room temperature for up to 3 days.

For longer storage, refrigerate for up to one week.

Can You Freeze Lemon Zucchini Bread?

Yes. Wrap each loaf tightly in plastic wrap, then cover with aluminum foil or place in a freezer bag. Freeze for up to 3 months.

Thaw overnight in the refrigerator or on the counter before serving.

Variations

Add white chocolate chips.
Stir in chopped pecans or walnuts.
Mix in fresh blueberries.
Use vanilla Greek yogurt for a milder lemon flavor.
Add poppy seeds for a lemon poppy seed version.

Lemon Zucchini Bread Frequently Asked Questions

Why is my zucchini bread dense?

Too much mixing develops the gluten and creates a heavier loaf. Mix only until the flour disappears.

Can I make muffins instead?

Yes. Fill muffin cups about two-thirds full and bake for 18 to 24 minutes.

Can I use yellow squash?

Yes. Yellow summer squash works just as well as zucchini

Can I skip the glaze?

Absolutely. The bread is delicious plain, but the glaze adds another layer of fresh lemon flavor.

Pro Tips

Measure flour correctly by spooning it into the measuring cup and leveling it off.
Use room temperature eggs and yogurt for a smoother batter.
Let the bread cool before glazing so the icing stays on top instead of soaking into the loaf.
The flavor becomes even better after resting overnight.
