Prepare the pan: Preheat the oven to 350F. Grease and lightly flour a 9×5 inch loaf pan and set aside.
Mix the dry ingredients: In a large bowl, combine the flour and baking powder.
Prepare the wet ingredients: In another bowl, beat the eggs and then add the oil and sugar, followed by the buttermilk, lemon juice, and lemon zest. Next, add finely grated zucchini to it.
Combine wet and dry mixtures: Stir the grated zucchini into the wet ingredients. Then add the wet mixture to the dry mixture and stir until just combined.
Bake: Pour the batter into the prepared loaf pan and bake for 45 minutes, or until a toothpick inserted into the center comes out clean.
Add the glaze: Cool the loaf in the pan for 10 minutes, then remove it to a wire rack to cool completely. For the glaze, mix the lemon juice and icing sugar and pour it over the completely cooled loaf.

Substitutions and Variations

Gluten-Free: If you’re looking to make this zucchini bread gluten-free, you can easily swap out the regular flour for a gluten-free alternative like almond flour or gluten-free all-purpose flour blend. Just make sure to check that your baking powder is also gluten-free.
Add-ins: You can add a variety of mix-ins to this lemon zucchini bread to suit your tastes, such as nuts, raisins, or chocolate chips, making it a versatile treat for any time of day.
Spices: For a different twist, you can add a dash of your favorite spices to the batter. A bit of cinnamon or a hint of nutmeg can give your lemon zucchini bread a warm, cozy flavor that’s perfect for the colder months.

Serving Suggestions

Breakfast: This lemon zucchini bread pairs perfectly with your morning coffee or can be served alongside an Italian frittata or some sheet pan buttermilk pancakes. The contrast of the sweet, tangy bread with these savory breakfast dishes is a real treat.
Condiments: For an extra touch of sweetness, consider serving this lemon zucchini bread with an extra drizzle of glaze or some honey. These condiments enhance the lemon flavor and make the bread even more indulgent.
Dessert: For a dessert that’s both refreshing and indulgent, try serving this zucchini bread with a scoop of vanilla ice cream or a fruit sorbet. The contrast of the creamy ice cream or tangy sorbet with the zesty bread is truly delicious.

How to Store Lemon Zucchini Bread

Store: To keep your lemon zucchini bread fresh, simply place it in an airtight container or wrap it tightly in plastic wrap and pop it into the fridge. It should stay fresh and tasty for up to a week.
Freeze: Freezing your lemon zucchini bread is also an option if you want to keep it for longer. Just make sure to wrap it in both plastic wrap and aluminum foil to prevent freezer burn. It can be kept in the freezer for up to three months.

Top Tips 

Don’t bother peeling the zucchini: There’s no need to peel the zucchini for this recipe. Just give it a good rinse and dry it off. The little green flecks actually look quite nice in the bread, and there’s no need to waste time peeling!
Make your own buttermilk: If you don’t have any buttermilk or can’t find it, make your own by mixing half a tablespoon of lemon juice or vinegar with half a cup of whole milk. Another option is half a cup of plain yogurt.
Don’t overmix the batter: When combining the wet and dry ingredients, stir until just combined. Overmixing your batter can lead to a tougher, less fluffy loaf.
Check your loaf before time is up: While the recipe suggests baking for 45 minutes, every oven is different. I recommend checking your loaf after 40 minutes to ensure it doesn’t over-bake, which can lead to a dry loaf.

Lemon Zucchini Loaf FAQs

Can I use a different type of flour for this lemon zucchini bread recipe?

Yes, you can use a different type of flour, such as almond flour or coconut flour, but keep in mind that these flours absorb more moisture, so you may need to adjust the liquid ingredients accordingly.

What can I substitute for buttermilk if I don’t have it on hand?

If you don’t have buttermilk, you can easily make a substitute by mixing half a tablespoon of lemon juice or vinegar with half a cup of whole milk. Another option is half a cup of plain yogurt.

Can I use bottled lemon juice instead of fresh lemon juice for this recipe?

While fresh lemon juice is always preferable for its bright, tangy flavor, you can use bottled lemon juice if that’s all you have. Just make sure it’s 100% pure lemon juice with no added preservatives or sweeteners.

How can I make sure I don’t overmix the batter?

To avoid overmixing, stir the wet and dry ingredients together until just combined. A few lumps in the batter are okay. It’s better to have a slightly uneven batter than to overmix and end up with a tough loaf.

What can I do if my bread isn’t baked through at 45 minutes?

If your bread is still not baked through at the 45-minute mark, you can cover it with foil to prevent the top from browning too much and continue baking, checking every 5-10 minutes until a toothpick inserted into the center comes out clean.

Can this lemon zucchini bread be made into muffins instead?

Yes, you can easily turn this recipe into muffins. Just adjust the baking time; they’ll likely take around 20 to 25 minutes to bake. The same rule applies, make sure not to overmix the batter.

What should I do if my glaze is too thick or thin?

If your glaze is too thick, add a drop of lemon juice at a time until it reaches the desired consistency. If it’s too thin, add a bit more icing sugar. Just remember to add any extra liquid or dry ingredients in small increments to avoid overdoing it.

    1. I haven’t tried this myself but if you are using applesauce you will need to reduce the amount (otherwise the batter will be too runny). I would suggest swapping the 2/3 cup of sugar for just under 1/2 cup of applesauce or one mashed banana. Because the fruit isn’t as sweet as the sugar, you might want to add some sugar or sweetener too, and it might take a little experimenting to get the flavor just right. Let me know how it works 🙂

  1. 5 stars
    This was delicious! I used melted butter instead of oil in the batter and added 1/4 tsp lemon extract along with the lemon juice in the glaze! Will definitely make again! Thanks for a great zucchini bread recipe!
