What You’ll Need
- 2 cups (about 250g) grated zucchini (about 2 medium zucchini)
- 2 cups (250g) all-purpose flour
- 1/2 cup (120ml) extra virgin olive oil
- 2/3 cup (130g) granulated sugar
- 2 large eggs
- 1 teaspoon vanilla extract
- 1 teaspoon baking soda
- 1/2 teaspoon baking powder
- 1/2 teaspoon salt
- 1/2 teaspoon ground cinnamon (optional, but recommended)
- 1/4 teaspoon ground nutmeg (optional)
- 1/2 cup (60g) chopped walnuts or pecans (optional)
- 1/2 cup (90g) chocolate chips or raisins (optional)
- Mixing bowls
- Box grater
- Whisk
- Spatula
- 9×5-inch loaf pan
- Parchment paper (optional, for easy removal)
- Cooling rack
Step-by-Step
- Preheat your oven. Set your oven to 350°F (175°C). Grease a 9×5-inch loaf pan with olive oil or nonstick spray. Line with parchment for easier removal if desired.
- Prepare the zucchini. Wash and dry your zucchini. Trim the ends and grate them using the coarse side of a box grater. No need to peel. Place the grated zucchini in a clean kitchen towel and gently squeeze out excess moisture, but don’t wring it completely dry—the bread needs some moisture.
- Mix the dry ingredients. In a medium bowl, whisk together the flour, baking soda, baking powder, salt, cinnamon, and nutmeg. Set aside.
- Mix the wet ingredients. In a large bowl, whisk together the olive oil and sugar until well combined. Add the eggs one at a time, beating well after each addition. Stir in the vanilla extract.
- Combine wet and dry mixtures. Add the dry ingredients to the wet ingredients and stir gently with a spatula until just combined. Do not overmix; a few streaks of flour are okay.
- Fold in zucchini and add-ins. Gently fold the grated zucchini into the batter. If using nuts, chocolate chips, or raisins, fold those in as well. The batter will be thick and slightly lumpy.
- Transfer to the loaf pan. Pour the batter into the prepared loaf pan. Smooth the top with a spatula. For a decorative touch, sprinkle a few extra nuts or chocolate chips on top.
- Bake. Place the pan in the preheated oven and bake for 50-60 minutes, or until a toothpick inserted in the center comes out clean or with just a few moist crumbs. Ovens vary, so start checking at 50 minutes.
- Cool. Remove the bread from the oven and let it cool in the pan for 10-15 minutes. Then run a knife around the edges and transfer to a wire rack to cool completely before slicing. This helps the crumb set and makes slicing easier.
- Serve and store. Slice and enjoy! Store leftovers tightly wrapped at room temperature for up to 2 days, or in the refrigerator for up to 5 days. For longer storage, freeze individual slices for up to 2 months.
Common Mistakes
- Skipping the moisture step: Not squeezing excess water out of the zucchini can make the bread too wet and gummy.
- Overmixing the batter: Stirring too much develops gluten, resulting in a tough, dense loaf.
- Overbaking or underbaking: Not checking early enough or removing too soon can leave the bread dry or undercooked in the center.
- Using too much olive oil: Exceeding the recommended amount can make the bread greasy and heavy.
- Not measuring flour properly: Scooping flour directly from the bag can compact it, leading to too much flour and a dry loaf. Spoon flour into your measuring cup and level it off.
Tips
- Choose mild olive oil: For the best flavor, use a light or mild extra virgin olive oil. Strong, peppery oils can overpower the bread’s subtle sweetness.
- Don’t peel the zucchini: The skin is thin, nutritious, and adds color and texture to your bread.
- Customize your mix-ins: Try walnuts, pecans, chocolate chips, or dried fruit, or keep it simple with just zucchini.
- Let it cool completely: Zucchini bread slices best when fully cool. Warm bread may crumble or appear gummy.
- Double the recipe: If you have extra zucchini, double the ingredients and bake two loaves—one for now, one for the freezer.
- Use parchment for easy removal: Lining the pan with parchment makes lifting the loaf out simple and helps prevent sticking.
- Serve in different ways: Toast a slice and spread with cream cheese, nut butter, or a drizzle of honey for a satisfying snack.
Troubleshooting
- Bread is too dense or gummy: This is often due to excess moisture from the zucchini or overmixing. Next time, squeeze the zucchini more thoroughly and mix the batter just until combined.
- Bread won’t rise: Check that your baking soda and powder are fresh. Expired leaveners won’t give the bread the lift it needs.
- Bread sticks to the pan: Make sure the pan is greased well, or use a parchment sling for easy removal. Run a knife around the edges after baking.
- Bread is dry: This can happen if you bake too long, use too much flour, or squeeze too much moisture from the zucchini. Next time, check for doneness at the minimum baking time and measure flour with the spoon-and-level method.
- Cracked top: This is normal for quick breads and gives a rustic look. It’s not a flaw, but if it’s excessive, your oven may be too hot—use an oven thermometer to check accuracy.
- Undercooked center: If the top is browning too fast but the center is still wet, tent the loaf with foil and continue baking until a toothpick comes out clean.
Frequently Asked Questions
- Can I use whole wheat flour instead of all-purpose?
- Yes, you can substitute up to half the flour with whole wheat for a nuttier flavor and denser texture. Using all whole wheat may make the bread heavy.
- Is olive oil zucchini bread healthy?
- It’s healthier than many quick breads, thanks to olive oil’s healthy fats and zucchini’s fiber and nutrients. However, it still contains sugar and should be enjoyed in moderation.
- Do I need to peel the zucchini?
- No, peeling is not necessary. The skin is mild and softens during baking, adding color and nutrition.
- Can I make this bread vegan?
- Yes, replace eggs with flax eggs (1 tablespoon flaxseed meal + 2.5 tablespoons water per egg) and use a plant-based milk if desired. The texture will be slightly different but still moist.
- How do I store leftovers?
- Wrap tightly and store at room temperature for up to 2 days, or refrigerate for up to 5 days. Freeze for longer storage, up to 2 months.
- Can I use yellow squash instead of zucchini?
- Yes, yellow summer squash works just as well. The flavor and moisture content are nearly identical.
