Blueberry Zucchini Bread Recipe (Moist & Easy)
Zucchini bread solves the late-summer glut of squash sitting on the counter, but add a handful of blueberries and it turns into something worth making on purpose. This blueberry zucchini bread recipe keeps the grated zucchini’s job — moisture, tenderness, a faint vegetal sweetness — while blueberries burst through the crumb in warm, jammy pockets.
It’s a one-bowl batter, no mixer required, and it forgives a slightly overgrown zucchini better than almost any other use for one.
Quick Answer
This blueberry zucchini bread recipe combines grated zucchini, fresh or frozen blueberries, warm spices, and a simple oil-based batter baked in a single loaf pan for about an hour. Squeezing excess water from the zucchini and tossing the blueberries in flour before folding them in are the two steps that keep the loaf moist without turning gummy or streaked purple.

Key Takeaways
- This blueberry zucchini bread recipe uses one bowl, no mixer, and about 20 minutes of hands-on prep.
- Squeezing grated zucchini dry before mixing is the single most important step for texture.
- Tossing blueberries in flour keeps them suspended through the loaf instead of sinking to the bottom.
- Fresh or frozen blueberries both work; frozen berries go in unthawed.
- The baked loaf keeps at room temperature for a couple of days and freezes well for up to three months.
Why You’ll Love This Blueberry Zucchini Bread Recipe
Grated zucchini is mostly water, and that water bakes into the crumb instead of evaporating off, which is why zucchini breads stay moist for days longer than most quick breads. Blueberries add their own pocket of moisture when they burst in the oven, plus a mild tartness that keeps the loaf from tasting flat or overly sweet.
There’s also a practical upside: this is a genuinely easy blueberry zucchini loaf recipe for using up a vegetable that tends to pile up faster than most households can cook it fresh. A single medium zucchini yields close to the amount this recipe calls for, so there’s rarely a need to buy extra.
Ingredients
- 1¾ cups (220g) all-purpose flour
- 1 teaspoon baking soda
- ½ teaspoon baking powder
- ½ teaspoon salt
- 1½ teaspoons ground cinnamon
- ¼ teaspoon ground nutmeg
- 2 large eggs, room temperature
- ½ cup (100g) granulated sugar
- ½ cup (110g) packed light brown sugar
- ½ cup (120ml) neutral oil, such as vegetable or melted coconut oil
- 1 teaspoon vanilla extract
- 1½ cups (about 1 medium zucchini, 180g) grated zucchini, squeezed dry
- 1½ cups (215g) fresh blueberries, or frozen and unthawed
- 1 tablespoon all-purpose flour, for tossing the blueberries
Ingredient Notes
Zucchini contributes very little flavor of its own but a great deal of moisture and a small amount of fiber and vitamin C, which is part of why USDA’s seasonal produce guide highlights summer squash as an easy vegetable to work into everyday cooking. There’s no need to peel it — the skin softens completely during baking and disappears into the crumb, leaving only small flecks of green.
Blueberries are the flavor anchor here. USDA’s blueberry guide notes they keep well refrigerated for up to two weeks, so buying a container ahead of baking day is fine. Room-temperature eggs blend into the oil and sugar more evenly than cold ones, which helps the batter come together smoothly without overmixing.
Substitutions
Whole wheat flour can replace up to half the all-purpose flour for a nuttier loaf, though the crumb will be slightly denser. Unsweetened applesauce can stand in for up to half the oil to cut some fat, but the loaf will be a touch less rich and may bake a few minutes faster — check it early.
A 1:1 gluten-free baking blend works in place of the all-purpose flour without major changes to the method. Yellow summer squash can substitute for zucchini in equal amounts if that’s what’s on hand.
Kitchen Tools Needed
- Box grater or food processor with a grating disc, for the zucchini
- A clean kitchen towel or cheesecloth, for squeezing out zucchini liquid
- 9×5-inch loaf pan
- Wire cooling rack
How to Make This Blueberry Zucchini Bread Recipe: Step-by-Step Instructions
1. Prep the oven and pan. Preheat the oven to 350°F (175°C). Grease a 9×5-inch loaf pan or line it with parchment, leaving an overhang on the long sides for easy removal.
2. Grate and drain the zucchini. Grate the zucchini on the large holes of a box grater. Pile it onto a clean towel, gather the edges, and squeeze firmly over the sink until the liquid stops running out. This should take about a minute of squeezing and removes several tablespoons of water.
3. Whisk the dry ingredients. In a medium bowl, whisk together the flour, baking soda, baking powder, salt, cinnamon, and nutmeg.
4. Whisk the wet ingredients. In a large bowl, whisk the eggs, granulated sugar, and brown sugar until smooth, about 30 seconds. Whisk in the oil and vanilla.
5. Combine. Add the dry ingredients to the wet ingredients and fold with a spatula just until no dry streaks remain. Fold in the drained zucchini.
6. Fold in the blueberries. Toss the blueberries with 1 tablespoon of flour in a small bowl, then fold them into the batter with just two or three strokes. Overmixing at this stage is what causes streaking.
7. Bake. Pour the batter into the prepared pan and smooth the top. Bake for 55–65 minutes, until a toothpick inserted in the center (avoiding a blueberry) comes out clean or with a few moist crumbs. Tent the loaf loosely with foil after 40 minutes if the top is browning too quickly.
8. Cool. Let the loaf cool in the pan for 15 minutes, then lift it out using the parchment overhang and cool completely on a wire rack, about 1½ hours, before slicing.
Expert Cooking Tips
- Squeeze the zucchini more than feels necessary — a well-drained loaf bakes evenly, while a wet one turns gummy in the center regardless of bake time.
- Fold the batter just until combined. Quick breads use baking soda and baking powder for lift, and overworking the gluten in the flour makes the crumb tough and tunnel-riddled rather than tender.
- Keep frozen blueberries frozen until the moment they go into the batter; thawed berries bleed color and turn the whole loaf gray-purple.
- Test doneness away from a blueberry pocket, since a toothpick through a berry will always look wet.
Common Mistakes to Avoid
- Skipping the zucchini squeeze. This is the most common cause of a dense, wet-centered loaf. Fix it by wringing the grated zucchini in a towel until it stops releasing liquid.
- Overmixing the batter. Stirring past the point of “just combined” develops gluten and produces a tough, rubbery crumb instead of a tender one. Stop folding as soon as the flour disappears.
- Thawing frozen blueberries first. Thawed berries release juice into the batter before baking, which streaks the crumb blue-gray. Add them frozen.
- Slicing too soon. A warm loaf is still setting internally; cutting it before it’s fully cool leads to a gummy, compressed slice even when the bread is fully baked.
Recipe Variations
- Lemon blueberry zucchini bread: Add 1 tablespoon lemon zest and 1 tablespoon lemon juice to the wet ingredients for brightness that plays well against the blueberries.
- Streusel-topped: Combine 3 tablespoons each of flour, brown sugar, and cold butter with a pinch of cinnamon, and sprinkle over the batter before baking.
- Muffins: Divide the batter among 12 lined muffin cups and bake at 350°F (175°C) for 18–22 minutes.
- Dairy-free: This recipe is already dairy-free as written, since it uses oil rather than butter.
Serving Suggestions
Serve slices plain, or with a thin layer of butter or cream cheese while still slightly warm. It also pairs well with a dollop of Greek yogurt and a scatter of extra fresh blueberries for a more breakfast-forward plate, or toasted and buttered the next day once the crumb has firmed up. Coffee or a black tea balances the sweetness well.

Blueberries are a source of anthocyanins, the plant pigments responsible for their color, and research summarized in Advances in Nutrition associates regular, moderate blueberry intake with antioxidant and anti-inflammatory activity, though this reflects eating blueberries generally rather than any specific claim about baked goods.
Working a vegetable like zucchini into a familiar recipe is also one of the practical approaches the CDC suggests for building more vegetables into everyday meals, alongside more direct swaps like adding vegetables to an omelet.
How to Store Blueberry Zucchini Bread
Once fully cooled, store the loaf in an airtight container at room temperature for up to 2 days, or in the refrigerator for up to 1 week — refrigeration extends freshness but can dry out the crumb slightly, so bring slices to room temperature or warm them briefly before eating.
For longer storage, wrap the whole loaf or individual slices tightly in plastic wrap and then foil, or place in a freezer bag with the air pressed out, and freeze for up to 3 months. USDA notes that freezing food quickly and packaging it well helps preserve texture and prevents the drying and discoloration that come from air exposure.
Thaw frozen slices at room temperature for about an hour, or microwave briefly, then reheat in a toaster or oven if a slightly crisp edge is wanted.
Make-Ahead Tips
The zucchini can be grated and squeezed dry up to a day ahead and kept covered in the refrigerator, which shortens active prep time on baking day. The baked loaf itself is a strong make-ahead option: it freezes cleanly, so baking it a few days or weeks before it’s needed and thawing it the morning of is often more convenient than baking same-day.
Blueberry Zucchini Bread Recipe FAQs
Do I need to peel the zucchini first?
No. The skin is thin, softens fully during baking, and adds small flecks of color along with a bit of extra fiber.
Should I thaw frozen blueberries before adding them?
No — add them straight from the freezer after tossing them in flour. Thawing first causes the berries to bleed and streak the batter.
Why did my zucchini bread come out gummy in the middle?
This is almost always excess moisture, either from zucchini that wasn’t squeezed thoroughly enough or from a loaf pulled from the oven before it finished baking. A clean toothpick test away from a berry pocket is the most reliable check.
Can I turn this into muffins instead of a loaf?
Yes. Divide the batter among 12 lined muffin cups and bake at 350°F (175°C) for 18–22 minutes, checking with a toothpick.
How do I keep the blueberries from sinking to the bottom?
Toss them in a tablespoon of flour before folding them in, and fold gently rather than stirring — a thicker batter and minimal mixing both help suspend the berries through the loaf.
Can I cut back on the sugar?
The sugar can be reduced by up to a quarter without major issues, though the loaf will be less moist and will brown less on top, since sugar contributes to both.
Conclusion
Of everything in this blueberry zucchini bread recipe, the zucchini-squeezing step does the most work: skip it, and no amount of extra bake time will fix a gummy center. Handle that one step well, keep the blueberries frozen until the last minute, and the rest of the recipe is close to foolproof.
