This easy low carb zucchini bread recipe with only 3 net carbs is also gluten-free, grain-free, sugar-free, and Trim Healthy Mama friendly.   

There are days when life is so hectic, and we are running in different directions. Crazy schedules mean less time available to spend in the kitchen. That is where I love this easy zucchini bread because it doesn’t take a lot of effort. Plus, we can quickly grab a piece and load up in the car or as a snack. 

One thing that makes this the best zucchini bread is its incredible moistness. It’s also the right amount of sweetness too. I am sure you will agree once you sink your teeth into a slice of bread. Sometimes I will eat some of this keto low carb zucchini bread as breakfast because it’s not overly sweet. 

If you love this try a couple of my other quick breads like my Keto Cinnamon Bread and my Protein Banana Bread Recipe.

Ingredients

Zucchini – Fresh shredded zucchini is the main ingredient in this. It gives extra moisture keeping the bread moist.

Almond Flour – Almond flour is a great low carb flour to use in keto diet recipes because it has low carbs and a mild flavor.

Coconut Flour – I like to use coconut flour in conjunction with almond flour because its natural dryness balances the natural oiliness of the almond flour.

Sweetener – I like to use a blend of granular sweeteners with stevia. This means you need less sweetener in total which lessens any aftertaste and decreases cost. I do offer alternatives to my blend in the recipe card.

Salted Butter – Using salted butter eliminates the need for adding too much salt when baking. The bit of salt in the butter balances the other flavors. Unsalted butter or coconut oil also work. Just add a pinch of salt.

Sour Cream – Sour cream helps keep the bread moist. Other alternatives are Greek yogurt or cream cheese.

Eggs – Eggs are the binder and necessary in this recipe.

Baking Powder – Always make sure your baking powder is fresh or your baked goods will not rise.

Vanilla Extract – Vanilla enhances the other natural flavors.

Cinnamon – I like a hint of cinnamon in my zucchini bread. You can omit it if you don’t.

Molasses – Yes, I use a bit of molasses in keto recipes and even in sugar free zucchini bread. I use it like an extract (for flavor) and not for sweetness. It adds a very minimal amount of carbs.

How To Make Keto Zucchini Bread

Step One: Prepare a standard loaf pan by lining it with parchment paper and preheat the oven to 350 degrees F. 

Step Two: Mix flour, sweetener, eggs, butter, sour cream, vanilla, molasses, cinnamon, and baking powder in a large bowl. Fold in the grated zucchini, then pour into the prepared loaf pan. Spread the batter evenly.

Step Three: Bake until golden brown and the batter doesn’t jiggle. For the last 20 minutes, cover with aluminum foil, so it doesn’t burn on top. Cool completely! 

Variations

This low carb keto zucchini bread recipe is SO versatile! You can add in almost anything you want, and it will taste fantastic. Here are a few ideas to try out next time you bake it. I would stick to 1/4 cup to 1/2 cup when adding any of the following:

Nuts – You will find walnuts in many traditional baking recipes because they are just so good. Almonds and pecans are also good choices.

Sugar Free Chocolate Chips – Stir in half of cup of chocolate chips for keto chocolate zucchini bread!

Blueberries – If you haven’t tried blueberry zucchini bread you have been missing out. Omit the cinnamon and add a cup of fresh blueberries or unthawed frozen blueberries. Adding in lemon extract or lemon zest along with the blueberries is incredible.

Storage

Store leftovers tightly covered with plastic wrap or in an airtight container in the fridge for 3-4 days. You can freeze the entire loaf or slices for longer storage.

Common Questions

Is Zucchini Bread Keto?

Traditional zucchini bread is not keto. It is typically made with wheat flour, white sugar, and brown sugar. By subbing in flours suitable for keto recipes and sugar free sweeteners you can make this classic sweet bread into a keto recipe.

Can Zucchini Bread Be Made Into Muffins?

Yes, absolutely you can turn this into some amazing zucchini bread muffins. Follow the recipe as directed, but instead of using a loaf pan, use a muffin tin instead. You will need only to bake them for 15-25 minutes instead of 50-55 minutes. Because the keto zucchini muffins would be smaller, they will take much less time. This is a great way to meal prep some snacks.

How Do You Shred Zucchini?

It’s always best to cut both ends off of your fresh zucchini.

Next, use a food processor or box grater to shred it. I do not drain my zucchini for this recipe.

Which Flour Has The Lowest Amount Of Carbs?

Coconut flour and almond flour have the least amount of carbs. Almond flour is a keto staple. I like to use them together as I do in this almond flour zucchini bread recipe.
