I’ve made this recipe plenty of times for family and friends, and it never lasts long on the counter.

This bread is the perfect use for garden-fresh zucchini and those handfuls of blueberries you don’t want to waste. Plus, it’s an easy bake for any skill level — from beginner to seasoned cook. You’ll love how the lemon glaze ties the whole loaf together, balancing sweetness with a little zing.

Ingredients for Moist Blueberry Zucchini Bread with Lemon Glaze

Here’s what you’ll want to have on hand before you start mixing up this delicious bread. I always find it helpful to measure out and prep everything first to keep the process smooth and stress-free.

• 2 cups shredded zucchini (about 2 medium zucchinis, squeezed gently to remove excess moisture but not dry)
• 1 ¾ cups all-purpose flour
• ¾ cup granulated sugar
• ½ cup packed light brown sugar
• 1 teaspoon baking soda
• ½ teaspoon baking powder
• ½ teaspoon salt
• 1 teaspoon ground cinnamon
• 2 large eggs
• ½ cup vegetable oil
• 1 teaspoon vanilla extract
• 1 cup fresh blueberries (if frozen, do not thaw; add directly to batter)

For the lemon glaze:

• 1 cup powdered sugar
• 2 tablespoons freshly squeezed lemon juice
• 1 teaspoon lemon zest (optional but highly recommended)

Be sure your zucchini is shredded finely but not watery. Too much moisture can make the bread soggy, and not enough can dry it out. Also, using fresh blueberries keeps the texture perfect in this loaf, giving bursts of flavor without bleeding too much color into the batter.

1 ¾ cups all-purpose flour

¾ cup granulated sugar

½ cup packed light brown sugar

1 teaspoon baking soda

Instructions

Preheat your oven to 350°F (175°C) and grease a 9×5-inch loaf pan or line it with parchment paper for easy removal later.

In a medium bowl, whisk together the flour, baking soda, baking powder, salt, and cinnamon to ensure even mixing and good rise.

In a large bowl, beat the eggs, granulated sugar, and brown sugar until smooth and glossy.

Add the vegetable oil and vanilla extract to the wet mixture and beat until combined.

Gradually fold the dry ingredients into the wet mix until no flour is visible, being careful not to overmix.

Fold in the shredded zucchini gently, then fold in the blueberries. Optionally toss blueberries in a little flour before folding to prevent sinking.

Pour the batter into the prepared loaf pan and smooth the top with a spatula.

Bake for 55–65 minutes, starting to check at 55 minutes using a toothpick in the center; it should come out clean or with a few moist crumbs.

Cool the bread in the pan for about 15 minutes, then remove and cool completely on a wire rack before glazing.

For the glaze, mix powdered sugar, lemon juice, and lemon zest until smooth, then drizzle evenly over the cooled bread.

Notes

Blueberry zucchini bread combines the subtle earthiness of zucchini with sweet blueberries in a moist bread, topped with a fresh lemon glaze for a bright punch. Perfect for breakfasts, snacks, or desserts with garden-fresh or frozen ingredients.

How to Prepare Moist Blueberry Zucchini Bread with Lemon Glaze

Baking this blueberry zucchini bread isn’t complicated, but there’s a rhythm that just makes it better. I’ll walk you through it step-by-step so you get the best texture and flavor every time.

1. Preheat your oven to 350°F (175°C) and grease a 9×5-inch loaf pan or line it with parchment paper for easy removal later.
2. In a medium bowl, whisk together the flour, baking soda, baking powder, salt, and cinnamon. This ensures your dry ingredients are evenly mixed and your bread rises well.
3. In a large bowl, beat the eggs, granulated sugar, and brown sugar until they mix smoothly and the sugar starts to dissolve — the mix will look glossy.
4. Add the vegetable oil and vanilla extract to the wet mixture, beating until combined.
5. Gradually fold the dry ingredients into the wet mix just until you don’t see flour anymore — don’t overmix, or the bread might get dense.
6. Fold in the shredded zucchini carefully, then gently fold in the blueberries. Tossing the blueberries in a spoonful of flour before adding helps keep them from sinking, but I don’t always bother if I’m short on time.
7. Pour the batter into your prepared loaf pan, smoothing the top with a spatula.
8. Bake for 55–65 minutes, but start checking at 55 minutes. Insert a toothpick in the center — it should come out clean or with just a few moist crumbs. If it’s wet, bake a little longer.
9. Once baked, cool the bread in the pan for about 15 minutes, then remove it to a wire rack to cool completely before glazing.
10. For the glaze, mix powdered sugar, lemon juice, and zest in a small bowl until smooth. Drizzle it evenly over the cooled bread. Don’t rush this step — the bread needs to be cool or the glaze will melt and run off.

From my experience, patience during cooling is your best friend here. And don’t worry if your loaf cracks a bit on top — it’s a sign of a good rise and doesn’t affect taste at all.

Storage & Reheating Instructions for Blueberry Zucchini Bread

Keeping your blueberry zucchini bread fresh is easy.

• Wrap cooled bread tightly in plastic wrap or store in an airtight container at room temperature for up to 3 days.
• If you want to keep it longer, freeze the loaf (wrapped well) for up to 3 months. Thaw overnight at room temperature.
• Reheat slices gently in the microwave for about 15-20 seconds or in a toaster oven for a few minutes if you want a little warmth and crisp edges.

Frequently Asked Questions About Moist Blueberry Zucchini Bread with Lemon Glaze

Can I substitute frozen blueberries for fresh in this recipe?

Yes! If you use frozen blueberries, don’t thaw them before adding to the batter. Frozen berries hold their shape better that way and reduce the risk of turning your batter blue and watery.

How much zucchini should I add for the best texture?

I usually use about 2 cups of shredded zucchini, which is roughly two medium zucchinis. It gives enough moisture and texture without making the loaf soggy. Remember to squeeze out some excess water gently but don’t dry it out completely.

Is this bread gluten-free or can it be made gluten-free?

This recipe uses all-purpose flour, which contains gluten. To make it gluten-free, use a gluten-free flour blend made for baking, but results may vary slightly in texture. Consider adding a bit of xanthan gum if your blend doesn’t include it.

Can I make this recipe vegan or dairy-free?

To make it vegan, replace the eggs with flax or chia egg substitutes and use a dairy-free oil like coconut or vegetable oil. Since there’s no dairy in this recipe beyond the glaze, swapping the lemon glaze to a vegan powdered sugar and lemon juice mix keeps it vegan-friendly.

What’s the best way to shred zucchini quickly?

Using the large holes on a box grater works well and is my method of choice. If you’re short on time, a food processor with a shredding attachment speeds things up with minimal mess.

Tips for Success with Moist Blueberry Zucchini Bread

• Don’t overmix your batter once adding the flour — it keeps your bread tender.
• Fresh lemon zest in the glaze adds a brightness that’s hard to skip.
• Use room temperature eggs; they mix better and help the bread rise nicely.
• Check the bread starting at 55 minutes; ovens vary, and over-baking dries it out.
• If your zucchini looks very watery, pat it dry with a towel but keep some moisture.
