Hearty Coconut Flour Zucchini Bread

Here’s my tried-and-true coconut flour zucchini bread recipe, made with fresh garden zucchini, warm spices, and a perfectly moist crumb thanks to the unique properties of coconut flour.

This zucchini bread has become my go-to way to use up summer squash when the garden is overflowing. I often bake two loaves at once – one for now and one for the freezer. And let’s be honest, there’s nothing better than a thick slice with your morning coffee, right?

What Kind of Zucchini Should I Use?

When it comes to making zucchini bread, medium-sized zucchini are your best bet since they tend to have the perfect balance of moisture and flesh. Really large zucchini can be a bit too watery and seedy, while tiny ones might not give you enough bang for your buck when grating. If your zucchini feels particularly watery, you can give it a gentle squeeze in a clean kitchen towel before adding it to your batter, though this recipe works fine either way. For the best results, look for firm zucchini with smooth, dark green skin and no soft spots – and don’t bother peeling them, as the skin adds nice flecks of color to your bread.

Options for Substitutions

This gluten-free zucchini bread is pretty adaptable! Here are some swaps you can try:

• Coconut flour: This is the one ingredient you shouldn’t substitute, as coconut flour has unique absorption properties that other flours don’t match. It’s essential for the right texture.
• Honey: You can swap honey with maple syrup or agave nectar in equal amounts. If using stevia, reduce to about 2-3 tablespoons and add 2 tablespoons of milk to maintain moisture.
• Nut butter: Any nut or seed butter works here – try almond, cashew, sunflower seed, or even tahini. Just make sure it’s well-stirred and not too dry.
• Flax meal: Ground chia seeds work as a 1:1 replacement, or you can use additional coconut flour (reduce to 3 tablespoons if doing this).
• Coconut oil: Melted butter or any neutral oil like avocado oil can replace coconut oil in the same amount.
• Zucchini: Yellow summer squash works just as well, or try carrots for a different twist. Just make sure to grate them finely.

Watch Out for These Mistakes While Baking

The biggest challenge when baking with coconut flour is managing its highly absorbent nature – using too much coconut flour or not having enough moisture can result in a dry, crumbly bread that’s hard to enjoy. A common mistake is not measuring the coconut flour precisely – even a small extra amount can throw off the entire recipe, so be sure to level off your measuring cup with a knife rather than eyeballing it. Another crucial step that’s often overlooked is properly draining the zucchini – while this recipe works with both squeezed and unsqueezed zucchini, removing excess moisture gives you more control over the final texture and prevents a soggy middle. For the best results, let the batter rest for 5-10 minutes before baking to allow the coconut flour to fully absorb the liquid ingredients, and don’t be tempted to open the oven door frequently while baking as this can cause the bread to sink in the middle.

What to Serve With Zucchini Bread?

This healthy zucchini bread is perfect for breakfast or as an afternoon snack, and there are lots of tasty ways to serve it! A warm slice spread with butter, cream cheese, or almond butter makes for a filling breakfast alongside your morning coffee or tea. For brunch, try serving it with a side of Greek yogurt and fresh berries to add some protein and natural sweetness to your plate. If you’re enjoying it as an afternoon treat, a cold glass of milk (regular or plant-based) pairs really nicely with the nutty, spiced flavors of the bread.

Storage Instructions

Counter Storage: This zucchini bread stays fresh at room temperature for about 2 days when wrapped well in plastic wrap or stored in an airtight container. If your kitchen is warm, it’s better to pop it in the fridge since it contains fresh zucchini.

Refrigerate: Keep your bread fresh for up to a week by storing it in the fridge in an airtight container. The coconut flour keeps it nice and moist, so you don’t have to worry about it drying out too quickly!

Freeze: This bread freezes really well! Slice it up before freezing, then wrap individual pieces in plastic wrap and store them in a freezer bag. It’ll stay good for up to 3 months. When you’re craving a piece, just grab a slice and let it thaw at room temperature for about an hour.

• Calories: 800-900
• Protein: 25-30 g
• Fat: 50-60 g
• Carbohydrates: 70-80 g

Ingredients

• 1 tsp ground cinnamon (or pumpkin pie spice)
• 1/2 tsp sea salt
• 2/3 cup mix-ins (such as chocolate chips, nuts, or dried cranberries)
• 1/3 cup nut or seed spread (I use almond butter)
• 3 eggs (room temperature for better emulsification)
• 1/4 cup ground flaxseed
• 1 tsp vanilla extract (pure vanilla preferred for best flavor)
• 1/4 cup coconut oil (melted and cooled slightly)
• 3/4 cup coconut flour (sifted to remove lumps)
• 1/3 cup honey
• 1 1/2 cups grated zucchini (excess moisture squeezed out)
• 2 tsp baking powder

Step 1: Prepare the Pan and Oven

Preheat your oven to 350°F and line a loaf pan with parchment paper, allowing the edges to hang over the sides for easy removal later.

This gives you time to prep ingredients while the oven reaches temperature.

Step 2: Sift Dry Ingredients and Prepare the Zucchini

• 3/4 cup coconut flour
• 1 1/2 cups grated zucchini

While the oven preheats, sift the coconut flour through a fine-mesh strainer to remove any lumps, which ensures a smooth batter texture.

In a separate bowl, grate the zucchini and squeeze out excess moisture using a clean kitchen towel or paper towels—this step is crucial because coconut flour is very absorbent, and excess moisture will make the bread soggy.

I like to use a box grater and really press the zucchini to get as much liquid out as possible, which dramatically improves the final texture.

Step 3: Build the Wet Ingredient Base

• 3 eggs
• 1/3 cup honey
• 1/3 cup nut or seed spread
• 1/4 cup coconut oil
• 1 tsp vanilla extract

In a large mixing bowl, whisk together the room-temperature eggs, honey, almond butter, melted coconut oil, and vanilla extract until well combined and smooth.

The room-temperature eggs emulsify better with the other ingredients, creating a more cohesive batter.

Whisk for about 1-2 minutes until the mixture is uniform and slightly lighter in color.

Step 4: Combine Dry Ingredients with Wet Mixture

• wet ingredient mixture from Step 3
• sifted coconut flour from Step 2
• 1/4 cup ground flaxseed
• 2 tsp baking powder
• 1 tsp ground cinnamon
• 1/2 tsp sea salt

Add the sifted coconut flour from Step 2, ground flaxseed, baking powder, cinnamon, and sea salt to the wet ingredient mixture from Step 3.

Whisk gently but thoroughly until all dry ingredients are fully incorporated and you have a smooth, thick batter with no visible lumps.

Be careful not to overmix, as this can develop gluten strands in the coconut flour.

I find that whisking for about 30-45 seconds is enough—you want everything combined but still tender.

Step 5: Fold in Zucchini and Mix-Ins

• grated zucchini from Step 2
• 2/3 cup mix-ins

Gently fold the squeezed zucchini from Step 2 and your choice of mix-ins (chocolate chips, nuts, or dried cranberries) into the batter from Step 4 using a spatula.

Use a folding motion rather than stirring to keep the batter tender and avoid overdeveloping the structure.

The zucchini will distribute moisture evenly throughout the bread as it bakes.

Step 6: Bake and Cool

• batter from Step 5

Pour the batter into your prepared loaf pan from Step 1, smoothing the top with a spatula.

Bake at 350°F for 50-60 minutes, until a toothpick inserted into the center comes out clean or with just a few moist crumbs.

The bread will rise and develop a light golden-brown top.

Allow the bread to cool in the pan for 30 minutes, then carefully lift it out using the parchment paper overhang and transfer it to a wire rack to cool completely.

This resting period in the pan helps the bread set properly without cracking.
