This blissful blueberry zucchini bread has been my secret weapon for sneaking vegetables into my family's diet while satisfying their sweet tooth. The hidden zucchini adds incredible moisture while the bursts of blueberries create pockets of sweet-tart flavor that elevate this from ordinary quick bread to something truly special.
I first made this bread when my garden produced a tsunami of zucchini and my children were becoming suspicious of my vegetable-heavy dinners. This bread changed everything - they devoured it without realizing they were eating vegetables!
Ingredients
- All purpose flour provides the perfect structure allowing the bread to rise beautifully
- Brown sugar adds depth and moisture that white sugar alone cannot achieve
- Fresh blueberries create juicy pockets of flavor choose plump firm berries without wrinkles for best results
- Zucchini is the secret moisture maker no need to squeeze out excess water the bread needs it
- Cinnamon enhances the sweetness while adding complexity select Ceylon cinnamon for a more delicate flavor
- Vanilla extract rounds out the flavor profile use pure not imitation for best results
- Vegetable oil keeps the bread moist longer than butter would
- Eggs bind everything together while adding richness
Step-by-Step Instructions
- Prepare Your Pan
- Thoroughly grease every corner of your loaf pan focusing on the bottom edges where sticking often occurs. A light dusting of flour after greasing provides extra insurance against sticking. Preheat your oven to 350°F allowing at least 15 minutes for it to reach proper temperature.
- Mix Wet Ingredients
- Combine the grated zucchini vegetable oil eggs and vanilla in a large bowl. The zucchini should be grated on the medium holes of a box grater leaving some texture rather than turning it to mush. No need to squeeze out moisture as this contributes to the breads incredible tenderness.
- Combine Dry Ingredients
- In a separate bowl whisk together the flour both sugars baking soda salt and cinnamon. Make sure to break up any brown sugar lumps with your fingers for even distribution throughout the batter.
- Create The Batter
- Pour the dry ingredients into the wet ingredient bowl not the other way around. Fold gently with a spatula using no more than 12 strokes. Overmixing activates gluten resulting in a tough bread. Some small streaks of flour are perfectly fine.
- Add Blueberries
- Gently fold in the fresh blueberries using just 5 or 6 additional strokes. Coating berries in a tablespoon of flour before adding prevents them from sinking to the bottom during baking.
- Bake To Perfection
- Pour the batter into your prepared pan and smooth the top with a spatula. Bake for 50 to 60 minutes until the top is golden brown and a toothpick inserted in the center comes out with just a few moist crumbs not wet batter.

The first time I served this to my mother in law she insisted I had purchased it from a bakery. When I revealed not only that I had made it but that it contained zucchini she nearly fell off her chair. Now she requests I bring it to every family gathering regardless of season.
Storing Your Bread
This zucchini blueberry bread actually improves with time as the flavors meld together. Store it at room temperature wrapped tightly in plastic wrap or in an airtight container for up to 3 days. The moisture from the zucchini keeps it from drying out like many quick breads tend to do. For longer storage refrigerate for up to a week or freeze individual slices separated by parchment paper for up to three months. Thaw slices at room temperature or pop them in the toaster for a warm treat.
Perfect Pairings
Transform this humble quick bread into an elegant dessert by warming a slice and topping it with a scoop of vanilla ice cream or a dollop of lemon-infused whipped cream. For breakfast a light smear of cream cheese creates a protein-rich start to your day. I often pack slices in lunchboxes where they hold up beautifully even when jostled. The bread also pairs wonderfully with afternoon tea or coffee especially when you need a sweet pick-me-up without the sugar crash that follows most treats.
Seasonal Adaptations
While summer offers the perfect opportunity to use garden-fresh ingredients this bread adapts beautifully year-round. In winter substitute frozen blueberries directly from the freezer no need to thaw which would create excess moisture. In fall add a handful of chopped walnuts or pecans for seasonal warmth. Spring brings the opportunity to add a tablespoon of fresh lemon zest brightening the flavors considerably. The recipe maintains its integrity regardless of these variations allowing you to enjoy it in every season.
Recipe FAQs

Yes, you can use frozen blueberries instead of fresh ones. To prevent color bleeding, don't thaw them first - add them frozen directly to the batter. You may need to extend baking time by 5-10 minutes.
- → How do I know when the bread is fully baked?
Insert a toothpick into the center of the loaf - it should come out clean or with a few moist crumbs, but no wet batter. The top should be golden brown and the bread may slightly pull away from the sides of the pan.
- → Do I need to squeeze moisture from the zucchini?
For this bread, you don't need to squeeze moisture from the zucchini as it helps keep the bread moist. However, if your zucchini seems extremely wet, you can lightly pat it with paper towels.
- → What's the best way to store this bread?
