Blueberry Zucchini Bread With Lemon Glaze tastes like a bright, moist lemon loaf that bumped into a blueberry muffin and decided to stay for brunch. It works perfectly for busy home bakers who want a quick loaf that feels special, with a total time of about 1 hour 15 minutes from grating zucchini to slicing. I first baked this on a Tuesday night “just to test it” and then ate three slices standing over the sink, so you could say I feel pretty invested in this recipe.

Why Make This Blueberry Zucchini Bread With Lemon Glaze at Home

Homemade Blueberry Zucchini Bread With Lemon Glaze gives you a super moist crumb, big pockets of juicy berries, and a fresh lemon finish that tastes bakery level without bakery prices. You control the sweetness, the amount of lemon, and the texture, so the loaf fits your taste instead of the other way around.

You also sneak in a whole cup of zucchini, which keeps the bread tender without tasting like vegetables. The batter comes together in one bowl with simple pantry staples, so you skip complicated steps and still pull a beautiful loaf out of the oven.

Ingredients You Need

Dry ingredients

All purpose flour: 2 cups, spooned and leveled
- Use a good basic brand like King Arthur or Gold Medal for consistent results.
Baking powder: 1 ½ teaspoons
Baking soda: ½ teaspoon
Fine sea salt: ½ teaspoon
Ground cinnamon: ½ teaspoon
- Optional, but it adds a cozy note that plays nicely with the lemon.

Wet ingredients

Large eggs: 2, at room temperature
Granulated sugar: ¾ cup
Light brown sugar: ¼ cup, packed
- Brown sugar adds moisture and a light caramel flavor.
Neutral oil: ½ cup (canola, vegetable, or light olive oil)
- Oil keeps the bread soft and tender longer than butter.
Plain Greek yogurt or sour cream: ½ cup
- This adds richness and helps the loaf stay moist.
Pure vanilla extract: 2 teaspoons
Fresh lemon zest: 1 tablespoon (about 1 large lemon)
Fresh lemon juice: 1 tablespoon

Add ins

Fresh zucchini: 1 cup, finely grated and lightly squeezed
- Do not peel; the green flecks look pretty and stay mild in flavor.
Fresh blueberries: 1 to 1 ¼ cups
- Rinse and pat dry very well so they do not bleed into the batter.
- You can use frozen blueberries; keep them frozen and toss in 1 teaspoon flour before folding into the batter.

Lemon glaze

Powdered sugar: 1 cup, sifted
Fresh lemon juice: 2 to 3 tablespoons
Lemon zest: ½ teaspoon
Pinch of salt: to balance the sweetness

Equipment

9 x 5 inch loaf pan
- You can use an 8 ½ x 4 ½ inch pan; the loaf will bake a bit taller and may need a few extra minutes.
Parchment paper
Mixing bowls: 1 large, 1 small
Whisk and rubber spatula
Box grater for zucchini
Cooling rack
Microplane or fine grater for lemon zest

Tips & Mistakes

Squeeze the zucchini gently, not aggressively, so it still holds some moisture and keeps the bread tender.
Dry the blueberries very well and toss them in a teaspoon of flour so they stay suspended in the batter instead of sinking.
Use room temperature eggs and yogurt so the batter mixes smoothly without clumps.
Line the loaf pan with parchment and leave a sling on the long sides so you lift the bread out easily without breaking it.
Do not overmix the batter; stir just until the flour disappears or the bread will turn dense and tough.
Check for doneness with a toothpick in the center; if it comes out with wet batter, keep baking in 5 minute increments.
Let the bread cool at least 20 to 30 minutes before glazing or the glaze will slide off and pool around the edges.
Zest the lemon before juicing it; zesting a squishy half lemon feels like a tiny workout no one asked for.

How to Make Blueberry Zucchini Bread With Lemon Glaze

Step 1: Prep the pan and oven

Preheat your oven to 350°F. Grease a 9 x 5 inch loaf pan with oil or nonstick spray, then line it with a strip of parchment that hangs over the long sides. Lightly grease the parchment as well so the loaf releases cleanly.

Step 2: Prep the zucchini and blueberries

Wash the zucchini and trim the ends. Grate it on the small holes of a box grater, then gather it in a clean kitchen towel and gently squeeze out excess moisture. Measure 1 cup of the lightly squeezed zucchini and set it aside.

Rinse the blueberries, drain them well, and pat them dry with paper towels. Toss them with 1 teaspoon of the flour from the measured amount. This light coating helps the berries stay evenly distributed in the loaf.

Step 3: Mix the dry ingredients

In a medium bowl, whisk together the flour, baking powder, baking soda, salt, and cinnamon. Break up any lumps so the mixture looks even and light. Set the bowl aside.

Step 4: Whisk the wet ingredients

In a large mixing bowl, whisk the eggs until they look slightly frothy. Add the granulated sugar and brown sugar and whisk until the mixture looks thick and glossy. Pour in the oil, yogurt, vanilla, lemon zest, and lemon juice, then whisk until everything combines into a smooth mixture.

Step 5: Combine wet and dry

Sprinkle the dry ingredients over the wet mixture. Use a rubber spatula to fold the flour in gently, turning the bowl and scraping from the bottom. Stop as soon as you no longer see dry streaks of flour.

Fold in the grated zucchini until it looks evenly distributed. Add the floured blueberries and fold them in gently so you do not crush them. The batter will look thick but scoopable.

Step 6: Bake the bread

Scoop the batter into the prepared loaf pan and smooth the top with your spatula. If you want a bakery style crack, run a butter knife in a shallow line down the center of the batter. Place the pan on the middle rack of the oven.

Bake for 50 to 60 minutes, depending on your oven and pan size. Start checking around 48 minutes. Insert a toothpick into the center; it should come out with a few moist crumbs but no wet batter.

Step 7: Cool the loaf

Place the pan on a cooling rack and let the bread cool in the pan for about 15 minutes. Use the parchment sling to lift the loaf out of the pan and set it directly on the rack. Let it cool until just barely warm before you add the lemon glaze.

Step 8: Mix the lemon glaze

In a small bowl, whisk the powdered sugar, 2 tablespoons lemon juice, lemon zest, and a tiny pinch of salt. The glaze should look thick but pourable, like heavy cream. If it looks too thick, whisk in another teaspoon of lemon juice; if it looks too thin, add a spoonful of powdered sugar.

Step 9: Glaze and slice

Place a sheet of parchment or a plate under the cooling rack to catch drips. Slowly pour the lemon glaze over the top of the loaf, letting it drip down the sides. Give the glaze about 15 minutes to set, then slice the Blueberry Zucchini Bread With Lemon Glaze with a sharp serrated knife.

Variations I’ve Tried

Lemon blueberry zucchini muffins: Scoop the batter into a greased or lined muffin tin and bake at 350°F for about 18 to 22 minutes. The glaze works perfectly on top of cooled muffins too.
Lemon coconut version: Fold ½ cup unsweetened shredded coconut into the batter with the zucchini. The coconut adds a little chew and a tropical note that pairs nicely with the lemon.
Whole wheat twist: Swap ½ cup of the all purpose flour with white whole wheat flour. The loaf turns slightly heartier but still stays moist and tender.
Nutty crunch: Add ½ cup chopped toasted walnuts or pecans. The nuts bring texture and balance the sweetness of the glaze.

How to Serve Blueberry Zucchini Bread With Lemon Glaze

Serve slices slightly warm or at room temperature so the lemon glaze softens and the crumb tastes extra tender. Pair a slice with hot coffee, tea, or a cold glass of milk for breakfast or an afternoon snack. Cut the loaf into small cubes and serve it in a fruit and yogurt parfait for a fun brunch twist. Pack slices in lunch boxes as a sweet treat that still sneaks in a bit of zucchini.

How to store

Room temperature: Store cooled Blueberry Zucchini Bread With Lemon Glaze in an airtight container at room temperature for up to 2 days. Place parchment between slices to keep the glaze from sticking.
Fridge: Keep the loaf in an airtight container in the refrigerator for 4 to 5 days. Let slices sit at room temperature for 15 minutes or warm them briefly in the microwave for 10 to 15 seconds.
Freezer: Wrap individual slices tightly in plastic, then place them in a freezer bag and freeze for up to 2 months. Thaw slices at room temperature or in the fridge overnight, then refresh in the microwave for 15 to 20 seconds or in a low oven at 300°F for about 8 minutes.
