Ingredients
Here’s what you need to make this healthy zucchini bread recipe! I also recommend you have an 8-inch by 4-inch loaf pan, parchment paper, and a large mixing bowl.
- Zucchini: This recipe is a great way to make something delicious using a spare zucchini. If you have leftover zucchini after making zucchini noodles for my healthy lemon picatta chicken, this is a great way to use it!
- Egg Whites: The whites of eggs are less caloric and have more protein than a whole egg.
- Unsweetened Applesauce: The natural sweetness from the apples sweetens this dessert bread without any sugar, and it provides moisture that eliminates the need for oil. Use leftover applesauce to make my apple cinnamon pancakes.
- Almond Extract: This extract adds a rich, nutty flavor to the zucchini bread. You can also use vanilla extract if you don’t have almond extract on hand.
- Oat Flour: This flour is packed with nutrients and helps the bread bake into a fluffy, appetizing texture.
- Mini Chocolate Chips: Get a mouthful of chocolate in every bite by using mini chocolate chips, but regular chocolate chips work well too. Use dairy-free chocolate chips if this needs to be a dairy-free recipe.
See the recipe card below for exact ingredient amounts, nutritional information, and detailed instructions.
Variations & Dietary Modifications
- Make It Sweeter: If your bread isn’t sweet enough for you, add a bit of honey or maple syrup as an additional natural sweetener. The nutritional information in the recipe card includes ¼ cup of honey in its calculations.
- Add More Protein: Make this bread higher in protein by substituting half of the applesauce with Greek yogurt. Keep in mind, healthy zucchini bread with Greek yogurt is less sweet, so you may want to use the extra honey in this scenario.
- Make Muffins: Turn this recipe into zucchini muffins or mini loaves by dividing the batter into a lined muffin tin. You could also just make my healthy chocolate chip zucchini muffins instead!
How to Make Low Calorie Zucchini Bread
This healthy zucchini bread is the perfect sweet treat for zucchini season, or to enjoy all year round. It’s lower in calories than your average zucchini bread, but it doesn’t sacrifice any of the flavor. Prepare your loaf pan by lining it with parchment paper. Let the ends of the paper hang over the sides of the pan for easy removal. You’ll also need to preheat your oven to 350°F.
Step 1: Combine the Wet Ingredients. In a large bowl, whisk together the egg whites, applesauce, salt, almond extract, and honey if you’re using it.
Step 2: Mix the Dry Ingredients. In a separate bowl, combine oat flour, baking soda, baking powder, and cinnamon. Then add the dry mixture to the wet mixture and stir to combine them.
Step 3: Add the Zucchini. Add the shredded zucchini and chocolate chips to the batter.
Step 4: Stir to Combine. Fold the zucchini and chocolate chips into the batter until just combined. Don’t overmix the batter!
Step 5: Transfer to Loaf Pan. Pour the batter into your prepared loaf pan and smooth it into an even layer. Bake at 350°F for 50-55 minutes, or until you can remove a toothpick clean from the center.
Step 6: Let It Cool. Allow the finished bread to cool for 1 hour in the pan before you remove it and slice it.
Expert Tips
- Shred Zucchini in the Food Processor: Make shredding the zucchini a breeze by using your food processor to pulse the zucchini until it reaches your desired consistency. Chop the zucchini into chunks before adding it to the food processor. A box grater for cheese works well too.
- Don’t Peel the Zucchini: There’s no need to peel the zucchini for this recipe! Just be sure to thoroughly wash it before shredding it.
- Don’t Overmix: Be sure to stop mixing the batter once everything is fully incorporated. An overworked batter will result in a dense zucchini bread.
- Remove Promptly from the Oven: Be sure to remove the zucchini bread from the oven when you can cleanly extract a toothpick. The bread will continue to cook in the hot loaf pan as it cools on the counter.
- Storing: Keep zucchini bread in an airtight container in the refrigerator up to 7 days or freeze up to 60 days.

- Have some zucchini bread with your breakfast! A high-protein breakfast like a berry and protein baked oatmeal or a butternut squash egg bake is the perfect option to pair with a moist zucchini bread.
Recipe FAQs
This recipe only calls for one zucchini, not a specific number of cups. It’s not necessary to be exact, but one medium zucchini typically yields about ¾ – 1 cup of shredded zucchini.
If your healthier zucchini bread turned out too wet, there may have been a lot of excess moisture in your zucchini. Try squeezing out some of the excess moisture with a cheesecloth or clean kitchen towel next time.
No, coconut flour will soak up too much of the moisture and make the bread very dry. Almond flour could work, but if you want to use it, I’d just recommend making my pumpkin almond flour muffins instead.
Wrap leftover slices of this healthy zucchini bread in plastic cling wrap and store it in the refrigerator for up to 10 days. You can also freeze the wrapped slices of bread for about 60 days. If you like warm zucchini bread, heat up your slices for about 30 seconds in the microwave before enjoying. Be sure to thaw frozen bread for at least 24 hours in the refrigerator before enjoying it!

Low Calorie Zucchini Bread
Ingredients
- 1 Small Zucchini, about 3/4 cup shredded
- 2 Egg Whites
- ½ cup Unsweetened Applesauce
- 1 teaspoon Almond Extract, or vanilla extract
- 1 ½ cups Oat Flour, or gluten free oat flour
- ½ teaspoon Salt
- ½ teaspoon Baking Soda
- 1 teaspoon Baking Powder
- 1 teaspoon Cinnamon
- ¼ cup Mini Chocolate Chips, or dairy free chocolate chips
- ¼ cup Honey, optional
Instructions
- Preheat oven to 350 F. Prepare a 8×4 loaf pan with parchment paper allowing the sides to hang over the edges of the pan for easy bread removal.
- Shred the zucchini by pulsing a few times in a blender or food processor. In a large bowl, whisk together eggs, applesauce, salt and almond extract. If adding optional honey, you will mix that in here.
- In a separate bowl, mix together the flour, baking soda, baking powder and cinnamon. Fold the flour mixture into the liquid mixture. Do not over mix. Next fold in the zucchini and chocolate chips into the batter. Transfer the batter to the prepared loaf pan and smooth into an even layer.
- Bake 50-55 minutes or until a toothpick removes clean from the center.
- Remove the bread from the oven and cool 1 hour in the pan before removing, slicing and enjoying!
Notes
- Use a food processor to shred the zucchini. It makes it so much easier and faster than shredding by hand! Just chop it into chunks before shredding it.
- You don’t need to peel the zucchini before shredding it because the skin is tender when cooked.
- Don’t over mix your batter, or the zucchini bread will turn out dense. Stop mixing when the ingredients are just incorporated for a fluffy bread.
- You can use rolled oats to make oat flour. I don’t recommend using quick oats.
- Store leftovers in the refrigerator up to 7 days or in the freezer up to 60 days.

I was a bit skeptical I’ll admit, but this cake/loaf is OUTSTANDING! I used 1/2 cup of powdered sweetener (Hermesetas) instead of honey, and I was debating whether to use almond essence or vanilla, but opted for the almond. I’m so glad I did! I might ease it back to 1/2 tsp next time though, but it was so much better than I thought it was going to be. And the calories are so low too! I used plain flour instead of oat flour as I find oat flour quite dry. This loaf is unreal, we all just devoured it. Thank you for all of your amazing recipes. I don’t often leave reviews, but this is definitely worthy!
Does the calories include the optional 1/4 cup of honey?
Yes, it is included.
How many cups of shredded zucchini do you use for this recipe?
I did not measure with cups for the recipe. I used one zucchini which I would guesstimate is 3/4 to 1 cup, but you don’t need to be so perfect for this recipe to turn out.
