from 5 votes

This impossibly moist Greek yogurt zucchini bread is a healthier twist on the classic quickbread, made with whole wheat flour, mashed bananas, olive oil and Greek yogurt. Soft, tender and studded with your choice of walnuts or chocolate chips, it’s one of my favorite ways to use up summer zucchini!

Healthy whole wheat zucchini bread with chopped walnuts.

Summer is in full swing, which means I have an abundance of zucchini from my mom’s vegetable garden. And what better way to use up all that summer squash than with endless loaves of healthy zucchini bread! It’s fluffy, moist and has quickly become a favorite in my household. With my four little ones, I’m always sneaking veggies into everything, and this bread makes it easy. The shredded zucchini adds moisture and nutrition without altering the taste – perfect for picky eaters!

But what makes this zucchini bread stand out from the rest? Let me share with you the five reasons why you’ll love this healthy summer bread.

5 Reasons You’ll Love This Healthy Zucchini Bread

  1. I made sure to keep it naturally sweet and avoid excessive refined sugars by using just a touch of brown sugar and a ½ cup of mashed banana. If you’ve ever tried my zucchini banana bread recipe, you already know that bananas and zucchini are a match made in quick bread heaven.
  2. I chose whole wheat flour for its nutty flavor and fiber boost, which makes each slice more filling and nutritious compared to quickbreads made with all-purpose flour. Even though I used whole wheat flour, this bread still turns out moist and tender.
  3. Instead of the usual milk or applesauce, I reached for one of my favorite baking ingredients: Greek yogurt. It adds moisture, a little extra protein and is the secret to a whole wheat zucchini bread that’s anything but dry. It’s the same trick I use in my Greek yogurt banana bread muffins.
  4. I used olive oil instead of butter to add healthy fats and keep the bread tender. See my ingredient notes for tips on choosing the best olive oil for baking.
  5. It’s made with ingredients you likely already have on hand, so you can whip it up anytime.

Ingredients

Two zucchinis and a ripe banana next to glass bowls containing olive oil, eggs, Greek yogurt, vanilla extract, baking soda, brown sugar, whole wheat flour and walnuts.
  • Whole wheat flour: A healthier alternative to all-purpose flour, adding extra fiber and a nutty flavor.
  • Brown sugar: Just ½ cup for sweetness.
  • Baking soda: Helps the bread rise perfectly.
  • Kosher salt: Enhances all the flavors.
  • 1 very ripe banana: You’ll need ½ cup of mashed bananas to add natural sweetness and to keep the bread moist.
  • Greek yogurt (whole or nonfat): Plain, unflavored Greek yogurt works best. If you love baking with Greek yogurt, don’t miss my extra-moist Greek yogurt banana bread.
  • Eggs: Bind everything together and add richness.
  • Zucchini: You’ll need 2 medium zucchini. Shred them using the large holes of a box grater, then measure out 1.5 cups. Wrap the shredded zucchini in a clean kitchen towel or dish towel and squeeze out as much liquid as possible before adding it to the batter.
  • Extra-virgin olive oil: The key to using olive oil in baking is to choose a mild, neutral-flavored one, such as this Colavita Olive Oil. If you don’t like using olive oil, you can use vegetable oil or melted coconut oil instead.
  • Vanilla extract: For flavor.
  • Optional add-ins: Keep your loaf plain or stir in up to 2/3 cup of chopped walnuts (my personal favorite!), pecans or chocolate chips. My four little taste-testers always request chocolate chips, just like they do whenever I make a loaf of my classic zucchini bread.

How to Make Greek Yogurt Zucchini Bread

This Greek yogurt zucchini bread comes together in just two bowls, no mixer required. Whisk the dry ingredients in one bowl and the wet ingredients, including the squeezed zucchini, in another. Pour the wet ingredients into the dry ingredients and stir gently until just combined.

The batter will be thick and a little lumpy.

Success tip: Stop mixing as soon as all the flour disappears. Overmixing develops the gluten in the flour, which can lead to a dense, tough loaf instead of a soft, tender one.

If you’re adding walnuts or chocolate chips, fold them in now. I also like to save a small handful to sprinkle over the top of the batter, along with a pinch of shredded zucchini, once it’s in the pan for a bakery-style finish.

Pour the batter into a parchment paper-lined 9-inch loaf pan and bake at 350°F for 50 to 60 minutes, until a toothpick inserted in the center comes out clean and the top is golden brown. Let the bread cool in the pan for 15 minutes before slicing so the crumb has time to set and every slice holds together beautifully.

Enjoy it warm for breakfast, an afternoon snack or even dessert. My favorite way to eat it? Slathered with a little (ahem… a lot of) homemade butter.

Tips and Variations

Storing & Freezing Instructions

Store this healthier zucchini bread in an airtight container or tightly wrapped in plastic wrap at room temperature. It will stay fresh for up to 3 days. For longer storage, transfer the wrapped bread to the refrigerator, where it can last up to a week.

It freezes great, too! You can either freeze the whole loaf, part of the loaf or even individual slices. Just be sure to wrap the bread tightly in plastic wrap, followed by aluminum foil to prevent freezer burn. It can be frozen for up to 3 months. Thaw overnight in the refrigerator or at room temperature before serving.

FAQs

Can I substitute honey or maple syrup for the brown sugar?

I don’t recommend it for this recipe. Both are sweeter than brown sugar and add more liquid to the batter, which will change the texture and likely leave you with a gummier loaf.

Can this batter be made into muffins?

Absolutely! Divide the batter among a greased or lined 12-cup muffin tin, filling each cup about two-thirds full, and bake at 350°F for 18 to 22 minutes, or until a toothpick inserted in the center comes out clean.

Can I use all-purpose flour instead of whole wheat flour?

Yes! The loaf will be a little lighter and more tender, with a milder flavor than the whole wheat version. Because whole wheat flour absorbs more liquid than all-purpose, the batter will be a touch wetter with this swap, so don’t be surprised if it needs a few extra minutes in the oven. Start checking with a toothpick around the original bake time and bake until a toothpick inserted in the center comes out clean.

Prep Time 10 minutes
Cook Time 1 hour
Total Time 1 hour 10 minutes
Servings 8 servings

Ingredients 

  • 1 3/4 cups whole wheat flour
  • 1/2 cup packed brown sugar
  • 1 teaspoon baking soda
  • 1/2 teaspoon kosher salt
  • 1/2 cup mashed very ripe bananas
  • 3/4 cup plain Greek yogurt, whole or nonfat
  • 2 large eggs
  • 1 1/2 cups shredded zucchini, drained (See Kelly’s Note)
  • 1/4 cup extra-virgin olive oil
  • 2 teaspoons vanilla extract
  • 2/3 cup chopped walnuts or chocolate chips (optional)

Instructions 

  • Preheat the oven to 350°F. Line a 9-inch loaf pan with parchment paper then grease the parchment paper with cooking spray.
  • In a medium bowl, whisk together flour, brown sugar, baking soda and salt.
  • In a separate medium bowl, whisk together the bananas, Greek yogurt, eggs, zucchini, olive oil and vanilla extract.
  • Add the wet ingredients to the dry ingredients and stir just until combined.
  • Stir in chopped nuts or chocolate chips (optional).
  • Pour the batter into the prepared pan.
  • Bake the bread until a toothpick inserted comes out clean, 50 to 60 minutes. Remove it from the oven and allow it to cool in the pan for 15 minutes before slicing and serving.

Kelly’s Notes

  • Draining as much moisture as possible from the zucchini is important to avoid a batter that is too wet and won’t bake through consistently.
  • Storing: Store in an airtight container or tightly wrapped in plastic wrap at room temperature. It will stay fresh for up to 3 days. For longer storage, transfer the wrapped bread to the refrigerator, where it can last up to a week.
  • Freezing: You can either freeze the whole loaf, part of the loaf or even individual slices. Just be sure to wrap the bread tightly in plastic wrap, followed by aluminum foil to prevent freezer burn. It can be frozen for up to 3 months. Thaw overnight in the refrigerator or at room temperature before serving.

    Hello,
    Because of my cancer I’m trying to eliminate Processed sugars as best possible.
    So my question is, have you ever used honey or maple syrup vs brown sugar?
    If so, are you using the same amount as the brown sugar & reducing the yogurt since it’s a wet ingredient?

    TIA

    1. Kelly Senyei says:

      Hi there! I would not suggest substituting in honey or maple syrup. Both are much sweeter than brown sugar and will also greatly alter the texture of the batter and bread. I’m sorry I don’t have a sub for the sugar in this recipe!

    I didn’t get to plant zucchini this year. But I happily find myself receiving zucchinis grown in friends’ gardens. What fun.

    I have fresh zucchini to make my favorite zucchini bread. I’ve used this recipe for years. I’ve tried others, but always come back to this Wisconsin farm-woman’s recipe. Here’s a link to the recipe and a story about garden-giving reciprocity. http://food-fun.wisconsinfood.com/edible_antics/2008/09/food-fun—givi.html
