A perfect zucchini bread recipe is so versatile and a great way to add extra vegetables to your day. You can serve it for brunch like you would a coffee cake. It’s also sweet enough to be a dessert, just add a scoop of vanilla ice cream. Or just have it as a midday snack!

While I do love a slice of chocolate chip zucchini bread, still warm with gooey melty chocolate chips, I think Lemon Zucchini Bread is a Summer’s favorite. You just can’t resist that refreshing flavor.

How to make Lemon Zucchini Bread

Zucchini bread is a type of quick bread, much like banana bread. The reason it is called “quick bread” is because it is leavened with baking soda and baking powder instead of yeast, so it is much quicker to make.

Making the lemon zucchini bread batter

  1. First, mix together lemon zest and sugar to release the lemon essential oil. Then beat the wet ingredients into the sugar mixture.
  2. Add the shredded zucchini and stir to distribute.
  3. Sift together flour, baking soda, and baking powder. Stir in the salt. Fold the dry ingredient mixture into the wet ingredient mixture. 
  4. Transfer the batter to a buttered loaf pan and bake for about 60 minutes at 350°F.
  5. Allow the lemon zucchini bread to cool inside the pan for 10 – 15 minutes before removing it to a wire rack to cool completely.

Lemon glaze 

You can forgo the optional lemon glaze, but I think it adds another burst of lemony goodness to this lemon zucchini bread. You could also try a homemade lemon curd as the topping instead of a sugar glaze.

Pouring lemon glaze over lemon zucchini bread

  • Whisk all the ingredients together in a small bowl.
  • Drizzle over completely cool zucchini bread.

Other Tips 

How to shred zucchini? 

Using the food processor to shred the zucchini is the quickest way, but you could also shred it by hand with a box grater or simply mince with your knife if that is your tool of choice.

What can I substitute sour cream with?

Sour cream can be substituted with plain yogurt or buttermilk.

Can this recipe be baked in a muffin pan?

Yes, this recipe will yield 12 regular size muffins. You’ll need to adjust the baking time to approximately 17 – 19 minutes at the same oven temperature.
