What You’ll Need
- 2 cups grated zucchini (from about 1 medium zucchini)
- 1 cup mashed ripe banana (about 2 medium bananas)
- 2 cups all-purpose flour
- 1 teaspoon baking soda
- 1/2 teaspoon baking powder
- 1/2 teaspoon salt
- 1 teaspoon ground cinnamon
- 1/2 teaspoon ground nutmeg (optional)
- 2 large eggs
- 3/4 cup granulated sugar (or half white, half brown sugar)
- 1/2 cup vegetable oil (or melted coconut oil)
- 1 teaspoon pure vanilla extract
- 1/2 cup chopped walnuts or pecans (optional)
- 1/2 cup chocolate chips (optional)
- Cooking spray or butter for greasing the pan
- 9×5-inch loaf pan
- Mixing bowls, measuring cups and spoons, whisk, spatula, box grater
Step-by-Step
- Prepare Ingredients
Preheat your oven to 350°F (175°C). Grease a 9×5-inch loaf pan with cooking spray or butter. - Grate and Drain Zucchini
Wash the zucchini, trim the ends, and grate it using a box grater. Place the grated zucchini in a clean kitchen towel, gather the ends, and squeeze out excess moisture over the sink. You want 2 cups of loosely packed, well-drained grated zucchini. - Mash Bananas
Peel the bananas and mash them in a bowl with a fork until smooth. Measure out 1 cup. - Combine Dry Ingredients
In a medium bowl, whisk together the flour, baking soda, baking powder, salt, cinnamon, and nutmeg (if using). - Mix Wet Ingredients
In a large bowl, whisk together the eggs and sugar until well combined and slightly pale. Add the oil and vanilla extract, whisking until smooth. Stir in the mashed banana. - Add Zucchini
Fold the grated, drained zucchini into the wet mixture, stirring gently to distribute evenly. - Combine Wet and Dry Ingredients
Add the dry ingredients to the wet mixture. Stir gently with a spatula until just combined—do not overmix. If using nuts or chocolate chips, fold them in now. - Pour and Smooth
Pour the batter into the prepared loaf pan. Smooth the top with a spatula. - Bake
Place the pan on the middle rack of the preheated oven. Bake for 55–65 minutes, or until a toothpick inserted in the center comes out clean or with a few moist crumbs (but no wet batter). - Cool
Remove the pan from the oven and let the bread cool in the pan for 10–15 minutes. Then run a knife around the edge and turn the loaf out onto a wire rack to cool completely before slicing. - Serve and Store
Slice and enjoy! Store leftover bread in an airtight container at room temperature for up to 3 days, or refrigerate for up to a week. For longer storage, wrap tightly and freeze for up to 3 months.
Common Mistakes
- Not draining zucchini enough: Excess moisture can make the bread dense or soggy. Always squeeze out as much liquid as possible.
- Overmixing the batter: Mixing too much after adding flour develops gluten, leading to tough bread. Stir just until combined.
- Using underripe bananas: Ripe, even overripe, bananas provide natural sweetness and moisture. Green or firm bananas won’t break down as well.
- Incorrect oven temperature: An oven that runs hot can burn the outside before the center cooks. Use an oven thermometer if possible.
- Not testing for doneness: Cutting into the bread too soon or removing it early can result in a gummy center. Always check with a toothpick.
- Not letting bread cool: Slicing while hot can cause the loaf to crumble or become gummy inside. Let it cool for best texture.
Tips
- Customize Mix-Ins: Add up to 1 cup total of chopped nuts, chocolate chips, dried fruit, or shredded coconut for variety.
- Use Brown Sugar for Depth: Replace part or all of the sugar with brown sugar for a richer flavor and extra moisture.
- Make Muffins: Use the same batter to make muffins—bake at 350°F for 18–22 minutes, or until a toothpick comes out clean.
- Gluten-Free Option: Substitute an all-purpose gluten-free flour blend for regular flour. Check that your baking powder is gluten-free.
- Vegan Adaptation: Use flax eggs (1 tablespoon ground flaxseed + 2.5 tablespoons water per egg) and plant-based oil. Make sure any add-ins are vegan.
- Double the Recipe: This bread freezes well. Make two loaves at once—enjoy one now and freeze the other for later.
- Spice It Up: Try adding ginger, cardamom, or orange zest for a flavor twist.
- Line the Pan for Easy Removal: For a super-easy release, line the loaf pan with parchment paper, leaving an overhang on the sides.
Troubleshooting
- Bread is gummy or undercooked in the middle: It likely needed more time in the oven or the zucchini was too wet. Place back in the oven for 5–10 more minutes if still warm, or toast slices individually if already cooled.
- Bread is dry or crumbly: Possible causes are overbaking, using too little banana or zucchini, or not enough oil. Next time, check the bread 5–10 minutes before the minimum baking time and test for doneness.
- Bread won’t rise: Check that your baking soda and baking powder are fresh. Expired leaveners can lead to dense, flat bread. Also, don’t overmix.
- Bread sticks to the pan: Make sure to grease well or line the pan with parchment. Running a knife around the edges while still warm helps release the loaf.
- Too bland: Spices can be increased, or try boosting flavor with extra vanilla, a pinch of salt, or a sprinkle of turbinado sugar on top before baking.
- Bread is too sweet/not sweet enough: Adjust the sugar next time by 1/4 cup up or down to taste. Keep in mind bananas add natural sweetness.
Frequently Asked Questions
- Can I use whole wheat flour instead of all-purpose?
- Yes, you can substitute up to half of the flour with whole wheat. The bread will be slightly denser and have a nuttier flavor. Using 100% whole wheat is possible, but expect a heavier loaf; you may want to add an extra tablespoon of oil and a splash of milk or water for moisture.
- Should I peel the zucchini?
- No, peeling is not necessary. The skin is thin and softens during baking, plus it adds color and nutrients. Just wash the zucchini well before grating.
- Can I freeze zucchini banana bread?
- Absolutely. Let the loaf cool completely, then wrap tightly in plastic wrap and foil, or place in a freezer bag. It keeps well for up to 3 months. Thaw at room temperature or in the fridge before serving.
- Can I make this bread without eggs?
- Yes, replace each egg with a flax egg (1 tablespoon ground flaxseed mixed with 2.5 tablespoons water, let sit for 5 minutes). The bread will be slightly denser but still moist and delicious.
- What can I use instead of oil?
- You can use melted coconut oil, melted butter, or even unsweetened applesauce for a lower-fat version. Applesauce will make the bread a bit more cake-like and less rich.
- How do I know when the bread is done?
- Insert a toothpick or skewer in the center. If it comes out clean or with just a few moist crumbs, it’s ready. If there’s wet batter, bake for another 5–10 minutes and check again.
