Zucchini bread with blueberries is a moist, flavorful twist on classic zucchini bread, combining the subtle earthiness of shredded zucchini with the tart sweetness of juicy blueberries. This recipe is perfect for using up summer zucchini and enjoying the burst of berries in every bite. Whether you’re baking for breakfast, snacks, or dessert, this bread is easy, adaptable, and crowd-pleasing. Before you begin, make sure you have fresh zucchini and blueberries, along with a few basic baking staples.
What You’ll Need
- 2 cups grated zucchini (about 1 medium-large zucchini)
- 1 cup fresh or frozen blueberries
- 2 cups all-purpose flour
- 3/4 cup granulated sugar
- 1/2 cup light brown sugar (packed)
- 2 large eggs
- 1/2 cup neutral oil (vegetable, canola, or melted coconut oil)
- 1 teaspoon vanilla extract
- 1 teaspoon baking soda
- 1/2 teaspoon baking powder
- 1/2 teaspoon salt
- 1 teaspoon ground cinnamon (optional)
- 1/4 teaspoon ground nutmeg (optional)
- 1 tablespoon lemon zest (optional, but brightens the flavor)
- 1 tablespoon flour (for coating blueberries)
- 9×5-inch loaf pan
- Parchment paper or nonstick spray
- Mixing bowls, whisk, spatula, box grater
Step-by-Step
- Preheat your oven. Set your oven to 350°F (175°C). Grease a 9×5-inch loaf pan with nonstick spray or line with parchment paper for easy removal.
- Prepare the zucchini. Wash and trim the ends off your zucchini. Grate the zucchini using the large holes of a box grater. Place the grated zucchini in a clean kitchen towel and gently squeeze out excess moisture. Measure 2 cups after squeezing. Set aside.
- Mix the dry ingredients. In a large mixing bowl, whisk together the flour, baking soda, baking powder, salt, cinnamon, and nutmeg. If using lemon zest, add it now.
- Combine wet ingredients. In a separate bowl, whisk together the eggs, granulated sugar, brown sugar, oil, and vanilla extract until smooth and well combined.
- Incorporate zucchini. Add the grated zucchini to the wet mixture and stir until evenly distributed.
- Combine wet and dry ingredients. Pour the wet mixture into the bowl with the dry ingredients. Stir gently with a spatula until just combined; do not overmix. The batter should be thick and slightly lumpy.
- Prepare blueberries. In a small bowl, toss the blueberries with 1 tablespoon of flour to help prevent them from sinking to the bottom during baking.
- Fold in the blueberries. Gently fold the coated blueberries into the batter, being careful not to crush them.
- Fill the pan. Pour the batter into the prepared loaf pan and smooth the top with a spatula.
- Bake. Place the pan in the preheated oven. Bake for 55–65 minutes, or until a toothpick inserted in the center comes out clean (a few moist crumbs are okay, but no wet batter).
- Cool. Remove the bread from the oven and let it cool in the pan for 10–15 minutes. Then, transfer the loaf to a wire rack to cool completely before slicing. This prevents the bread from becoming gummy.
- Slice and serve. Once fully cooled, slice the bread with a serrated knife. Serve as is, or with a pat of butter or cream cheese.
Common Mistakes
- Skipping the zucchini draining step: Excess moisture can make the bread dense or soggy. Always squeeze the grated zucchini before adding it.
- Overmixing the batter: Overmixing develops gluten, resulting in tough, rubbery bread. Stir until just combined.
- Using too many blueberries: Overloading the batter with berries can weigh it down and cause uneven baking. Stick to about 1 cup.
- Not coating blueberries in flour: Uncoated berries are more likely to sink to the bottom of the loaf.
- Underbaking or overbaking: Not checking for doneness can lead to an overly wet or dry loaf. Test with a toothpick for best results.
- Slicing while hot: Cutting the bread before it cools can cause it to fall apart or become gummy.
Tips
- Use fresh or frozen blueberries: Both work well. If using frozen, do not thaw before adding to the batter—this helps prevent bleeding.
- Add lemon zest: Lemon zest brightens the flavor and pairs beautifully with blueberries.
- Make it healthier: Substitute half the all-purpose flour with whole wheat flour, or use a portion of applesauce instead of oil for a lighter loaf.
- Flavor variations: Try adding chopped nuts (like walnuts or pecans) or a handful of shredded coconut for extra texture.
- Double the recipe: Make two loaves and freeze one for later. Zucchini bread freezes very well when wrapped tightly.
- Storage: Store cooled bread in an airtight container at room temperature for up to 2 days, or in the refrigerator for up to 5 days. For longer storage, freeze slices for up to 3 months.
Troubleshooting
- Bread is too wet or dense: This often means the zucchini wasn’t drained enough or the bread is underbaked. Next time, squeeze the zucchini thoroughly and bake until a toothpick comes out clean. If the loaf is still salvageable, return it to the oven (covered with foil) for an additional 10–15 minutes.
- Blueberries all sank to the bottom: Toss blueberries in flour before folding into the batter. If you forgot, the bread will still taste good, but the berries will be concentrated at the base.
- Bread stuck to the pan: Always grease your pan well and consider using parchment paper for easy removal. If stuck, run a thin knife around the edges and let the bread cool further before trying again.
- Bread is gummy in the middle: This usually means it was sliced before cooling or is underbaked. Let the bread cool completely on a wire rack, and next time, test for doneness before removing from the oven.
- Bread is too dry: Overbaking or using too little zucchini can dry out the loaf. Store leftovers wrapped tightly, and try serving with a spread if it feels dry.
Frequently Asked Questions
- Can I use frozen blueberries instead of fresh?
- Yes, frozen blueberries work well. Add them straight from the freezer and toss with flour before folding into the batter to avoid excess bleeding.
- Should I peel the zucchini?
- No, there’s no need to peel zucchini. The skin is thin, adds nutrients, and disappears into the bread after baking.
- Can I make this recipe gluten-free?
- Yes, substitute a 1:1 gluten-free flour blend for the all-purpose flour. The texture may vary slightly, but it will work.
- What’s the best way to store zucchini bread?
- After cooling, wrap the bread tightly and store at room temperature for up to 2 days, or refrigerate for up to 5 days. Freeze slices for longer storage.
- Can I reduce the sugar?
- Yes, you can reduce the sugar by 1/4 cup without significantly affecting texture, though the bread will be less sweet.
- Why does my bread come out gummy?
- This usually happens if the zucchini wasn’t drained well, the bread is underbaked, or it was sliced while still warm. Be sure to follow the draining and cooling steps.
