Tender Whole Wheat Zucchini Bread

Here’s my go-to whole wheat zucchini bread recipe that combines the goodness of whole wheat flour with fresh garden zucchini. The result is a moist, hearty bread that’s perfect for breakfast or an afternoon snack.

This zucchini bread has become a summer tradition in our house, especially when the garden is overflowing with zucchini. I often make a double batch – one loaf for now and one for the freezer. Because let’s be honest, there’s nothing better than homemade bread with your morning coffee, right?

What Kind of Zucchini Should I Use?

For zucchini bread, medium-sized zucchini (about 8 inches long) are your best bet since they’re tender and have smaller seeds than the giant ones you might find in late summer. If you do end up with larger zucchini, just be sure to cut them lengthwise and scoop out the seedy center before grating. When it comes to prepping, you don’t need to peel your zucchini – the skin adds nice flecks of green to your bread and contains extra nutrients. Before adding the shredded zucchini to your batter, give it a gentle squeeze to remove some excess moisture, but don’t go overboard – that natural moisture helps keep your bread nice and moist.

Options for Substitutions

This zucchini bread recipe is pretty adaptable and here are some helpful swaps you can try:

• Whole wheat flour: You can use all-purpose flour instead of whole wheat, or try a 50/50 mix of both. For a gluten-free version, use a 1:1 gluten-free flour blend – just make sure it contains xanthan gum.
• Sugar: Feel free to reduce the sugar by up to 1/3 cup, or replace up to half with honey or maple syrup (if using liquid sweeteners, reduce the oil by 2 tablespoons to maintain moisture balance).
• Canola oil: Any neutral oil works here – try vegetable oil, melted coconut oil, or melted butter. Applesauce can replace half the oil for a lighter version.
• Eggs: For each egg, you can use 1/4 cup mashed banana or 1 tablespoon ground flaxseed mixed with 3 tablespoons water (let sit for 5 minutes before using).
• Spices: No cloves? Use nutmeg instead. You can also add other warm spices like ginger or allspice, or skip the cloves entirely and just stick with cinnamon.
• Zucchini: This is the star ingredient and can’t be substituted, but make sure to squeeze out excess moisture after shredding to prevent a soggy bread.

Watch Out for These Mistakes While Baking

The biggest challenge when making whole wheat zucchini bread is ending up with a dense, heavy loaf – to avoid this, make sure not to overmix the batter once you’ve combined the wet and dry ingredients, as this develops too much gluten and creates a tough texture. Another common mistake is not properly draining the shredded zucchini, which can add too much moisture to your bread – try placing the shredded zucchini in a clean kitchen towel and giving it a gentle squeeze to remove excess water before adding it to your batter. When measuring your whole wheat flour, avoid scooping directly with the measuring cup, instead spoon the flour into the cup and level it off with a knife to prevent using too much flour, which can make your bread dry. For the best texture, let the bread cool completely (at least 1 hour) before slicing, as cutting into it too soon can make it gummy and dense.

What to Serve With Zucchini Bread?

This wholesome zucchini bread makes a perfect breakfast or afternoon snack, and there are lots of tasty ways to enjoy it! A warm slice spread with butter or cream cheese is my go-to way to serve it, especially alongside a hot cup of coffee or tea. For breakfast, try pairing it with some Greek yogurt and fresh berries, which adds protein and makes it more filling. If you’re serving it for dessert, a light spread of honey butter or a dollop of whipped cream can make it feel extra special without being too heavy.

Storage Instructions

Counter Storage: Your freshly baked zucchini bread will stay good at room temperature for about 2-3 days. Just wrap it well in plastic wrap or keep it in an airtight container. I like to place a paper towel in the container to absorb any extra moisture from the zucchini.

Refrigerate: Want it to last longer? Pop your wrapped zucchini bread in the fridge where it’ll stay fresh for up to a week. The whole wheat flour actually helps it maintain its moisture really well!

Freeze: This bread is perfect for freezing! Let it cool completely, wrap it tightly in plastic wrap, then aluminum foil, and freeze for up to 3 months. You can even slice it before freezing – just put some parchment paper between slices so they don’t stick together.

Thaw & Enjoy: When you’re ready to eat your frozen zucchini bread, just let it thaw overnight in the fridge or for a few hours on the counter. Give it a quick 10-second zap in the microwave if you like it warm, and it’ll taste just like freshly baked!

• Calories: 2300-2500
• Protein: 30-40 g
• Fat: 100-120 g
• Carbohydrates: 350-370 g

Ingredients

• 1 tsp ground cinnamon (freshly ground preferred for more flavor)
• 1 2/3 cups sugar
• 1 tsp salt
• 2/3 cup canola oil (or melted Kerrygold butter for richness)
• 3 cups grated zucchini (squeeze out excess moisture before measuring)
• 1/4 tsp ground cloves
• 3 cups whole wheat flour (King Arthur brand recommended)
• 4 eggs (room temperature for better mixing)
• 2 tsp vanilla extract (for best flavor and aroma)
• 1/2 tsp baking powder
• 2 tsp baking soda

Step 1: Prepare Equipment and Mise en Place

• 3 cups zucchini, grated and squeezed

Preheat your oven to 350°F and grease two loaf pans thoroughly with butter or cooking spray, making sure to coat the bottom and sides evenly to prevent sticking.

While the oven heats, grate your zucchini using the large holes of a box grater, then place it in a clean kitchen towel and squeeze firmly over the sink to remove excess moisture—this step is crucial because too much liquid will make the bread soggy.

Set the squeezed zucchini aside in a small bowl.

Step 2: Mix Dry Ingredients

• 3 cups whole wheat flour
• 1 tsp salt
• 1 tsp ground cinnamon
• 1/4 tsp ground cloves
• 2 tsp baking soda
• 1/2 tsp baking powder

In a medium bowl, whisk together the whole wheat flour, salt, ground cinnamon, ground cloves, baking soda, and baking powder.

Make sure to break up any lumps in the cinnamon and cloves so they distribute evenly throughout the flour mixture.

I like to sift these spices together for the most delicate crumb texture, especially when using whole wheat flour which can sometimes be dense.

Set this dry mixture aside.

Step 3: Create the Wet Ingredient Base

• 1 2/3 cups sugar
• 2/3 cup canola oil
• 2 tsp vanilla extract
• 4 eggs
• grated zucchini from Step 1

In a large mixing bowl, whisk together the sugar and canola oil (or melted butter) until well combined, about 1-2 minutes.

Add the vanilla extract and mix briefly, then add the room-temperature eggs one at a time, whisking well after each addition to ensure they’re fully incorporated—this creates a lighter, more cohesive batter than dumping them all in at once.

Gently fold in the squeezed zucchini from Step 1 until evenly distributed throughout the wet mixture.

Step 4: Combine Wet and Dry Ingredients

• wet ingredient mixture from Step 3
• dry ingredient mixture from Step 2

Pour the wet ingredient mixture from Step 3 into the bowl with the dry ingredient mixture from Step 2.

Using a rubber spatula or wooden spoon, fold the two mixtures together gently until just combined—don’t overmix, as this can develop too much gluten and make the bread tough.

A few small lumps are perfectly fine and will actually contribute to a more tender crumb.

I prefer to stop mixing when I can no longer see streaks of flour rather than mixing until completely smooth.

Step 5: Fill Pans and Bake

• combined batter from Step 4

Divide the batter evenly between the two prepared loaf pans, smoothing the tops gently with a spatula.

Place both pans on the center rack of your preheated 350°F oven and bake for 40 minutes, until a toothpick inserted into the center of each loaf comes out clean or with just a few moist crumbs.

The tops should be golden brown and the bread should spring back slightly when gently pressed.

Step 6: Cool and Finish

Remove the pans from the oven and let the bread cool in the pans for 20 minutes—this allows the structure to set and makes removal easier.

After 20 minutes, turn the loaves out onto a wire cooling rack to cool completely before slicing.

For the best texture and flavor, wait until the bread is completely cool before slicing, which helps the tender crumb hold together better.
