Keto Zucchini Bread [Coconut Flour]

Moist, dense, slightly sweet this keto zucchini bread is flat-out delicious and a great way to add more fiber to your keto diet.

Made with coconut flour and shredded zucchini, it’s the perfect summer quick bread recipe for when zucchini is at the height of its season. 

I enjoy transforming my favorite traditional recipes into healthy keto-friendly options. And this recipe for coconut flour zucchini bread doesn’t disappoint.

It’s sure to fool your tastebuds and will be welcomed by even those who are not doing keto.

A high-fiber zucchini bread recipe is perfect for a quick healthy breakfast, or anytime you want a snack that will keep you full until your next meal.

This keto zucchini coconut flour bread was loosely inspired by our keto “banana” bread recipe. It has a similar texture and it’s also part of our keto high fiber recipes.

I have quite a number of quick bread options on the site so be sure to check out our keto bread recipes for more of the same.

This low carb zucchini bread is made with coconut flour and if you leave out the walnuts, it’s a tree-nut-free option.

You can even make it dairy-free by substituting the melted butter for coconut oil and the heavy cream for your choice of almond or coconut milk.

You can choose to grate the zucchini with a box grater or a food processer. Just note that the pieces will be finer if using a food processor. 

I used my food processer and liked how quickly I was able to make a keto zucchini bread recipe. 

Creating more coconut flour recipes became a priority for me when I learned how much more economical it is to use compared to almond flour and that it’s a great nut-free option for those who have nut allergies but can consume coconut. 

Can You Use Frozen Zucchini For Zucchini Bread

For those of you who are fortunate enough to grow your own zucchini, you know that it’s one vegetable that gives a bountiful harvest. 

Zucchini that has been frozen can certainly be used in zucchini bread. The key is to start by choosing younger zucchini that is more slender and no more than 2 inches in diameter. This will ensure that when grated it does not produce excess water.

I recommend that you grate your fresh zucchini and then squeeze dry as much of the liquid before adding 1 cup portions to a freezer bag. 

Freezing zucchini is a great way to enjoy zucchini all year round. Then once you want to use it in the recipe, just allow the shredded zucchini to thaw. 

High Fiber Zucchini Keto Bread

I am a proponent of adding more fiber to our keto diet because in my book low carb does not translate into zero carbs. Using a delicious recipe like this low carb zucchini bread is a tasty way to add more fiber to your diet.

As an added benefit grated zucchini allows this coconut flour-based bread to be moist. It’s why I think it’s the best keto zucchini bread recipe. 

Personally, I am not a fan of zero-carb diets that advocate no dietary fiber. After all, we have plenty of studies that point to dietary fiber being essential

With that being said, it can be a bit challenging to add more “roughage”, the parts of plants that our bodies don’t digest while doing a ketogenic diet. 

This is because most people doing a low-carb diet are just not eating enough vegetables for fear of adding too many carbs to their diet. 

My solution is to add extra fiber in the form of prebiotics a type of fiber that passes through the upper region of the gastrointestinal tract and stimulates the growth of beneficial bacteria. Thankfully, coconut flour is a form of prebiotic.

I also add soluble fiber, in the form of psyllium powder which when digested creates gel-like consistency ou our digestive tract and it’s what keeps us regular and our hunger at bay by making us feel satiated longer.

The Best Sugar Substitute For Low Carb Zucchini Bread

When it comes to choosing which sugar substitute to use for this sugar-free zucchini bread, I have several for you to choose from. 

I am recommending you use a brown sugar substitute in this recipe. I used Lakanto’s golden monkfruit

Although you can use their white granulated sweetener exclusively it will not have the same depth of flavor and the bread will be lighter.

Having said that, I’m also partial to the brand Swerve brown sugar which is an erythritol blend. Similar to Lakanto it uses sugar alcohols and has a 0 % impact on blood sugar.

Surkin gold is another delicious substitute for brown sugar and one I have also used. I find the texture of Surkin is closest to traditional brown sugar.
