Zucchini Recipes

Everyone is always looking for zucchini recipes during the summer months when zucchini is out of control, myself included.  Our good friends gave us a zucchini the size of a baseball bat from their garden. I am trying to come up with creative ways to use our humongous zucchini. I love making my favorite zucchini breads, chocolate and lemon, but I wanted to try something new. Last night, we needed a dessert to take to a party, so I made chocolate chip zucchini brownies. Yes, dessert is always needed, especially when zucchini brownies are involved. They are SO good and one of my favorite summer desserts.

Magic Zucchini Brownies

I love baking with zucchini. You start with a green vegetable and end with a decadent dessert. I kind of feel like a magician because people are always so surprised when they find out zucchini is involved. Zucchini really is a magic ingredient. Zucchini makes these brownies extra special.

When I pull a warm pan of brownies out of the oven everyone always gathers around for a taste because they don’t look like zucchini brownies, they look like a pan of fudgy, chocolaty brownies! Everyone lines up for a taste! They are always blown away because these brownies are perfection! They are so rich and delicious!

A few tips for making zucchini brownies:

  • You can use a large or small zucchini, the size doesn’t matter. I know a lot of people like to use overgrown zucchini for baking and that is just fine. Don’t let those big zucchini go to waste.
  • Shred the zucchini with a cheese grater or food processor. I never peel the zucchini.
  • I don’t squeeze out the moisture in the zucchini for this recipe. You want the brownies to be moist. If your zucchini is extra watery, you can squeeze it out a little in a paper towel, but don’t get rid of all of the moisture.
  • The mixture will look dry when you start and that is ok. It will be just fine after you add in the zucchini. Just be patient:)
  • Stir in 1 cup of the chocolate chips into the batter and save 1/4 cup for sprinkling on top. The chocolate chips make the brownies even more chocolaty, which is a very good thing!
  • This recipe makes a 9×13-inch pan, which makes this brownie recipe a great one to share!
  • Pro tip-cut the brownies with a plastic knife after they have cooled. A plastic knife is magic and doesn’t make a lot of crumbs.

If you are still looking for ways to use up your garden zucchini, give these chocolate chip zucchini brownies a try! They are a favorite at our house!

  1. Just a tip, you can totally substitute unsweetened apple sauce for the oil, you’ll never know the difference . Just as moist & yummy , less fat and more vitamins

    I made this recipe today and must say they turned out very good. I have a son and daughter in law with food restrictions so finding recipes that they can eat can be tough. This is one that they can enjoy and will become a family favorite. Thank you.

  3. I want to try these ..but dont like Chocolate chips..don’t know how it’s going to work but I’m going to try white chocolate chips..Cocoa is fine ..just not chocolate except white

    1. I made them without the chocolate chips and they were divine! I may add nuts next time because I like nuts in my brownies.

    These are the moistest brownies I have ever made! They were a huge hit. I peeled the zucchini so that the picky eaters would not recognize it. They ate them and asked for more!

      Love this recipe. Have made several times . Moist and delicious. Most importantly, no one thought there was healthy zucchini in them. I find that if the zucchini is watery, I’ll squeeze some of the liquid out but save it. If it seems dry will add a little of the liquid until desired consistency. I also bake the brownies in my cast iron pan. Thank you for an easy and delicious treat!

    I had the same issue as some other readers – the batter was crumbly and would not have poured into the pan so I assed abou 1/3 cup of water which turned it into a wonderful batter (of course I taste-tested)! The issue must have been that my zucchini wasn’t moist enough, but adding the water did the trick. They are baking now, thanks for a great idea. 

    1. Mine was very dry like sand, I read the reviews until I saw yours and added the water they are must better now and are baking! Thanks for your review 🙂

    Just made two batches of these gorgeous brownies – one as a Thank You and the other for weekend company. I couldn’t resist and took a small piece – amazing- so good. Thank you for a great, easy to make brownie recipe. I was worried at first that my zucchini was dry but I just mixed the batter a little longer and everything incorporated well and turned out perfectly.

    Amazing. My son said it was the best thing he’s ever eaten. A few bites in I told them they were zucchini brownies and they didn’t care.

  8. I just got this recipe from a friend last week, and I have got nothing but rave reviews on these. I am taking them to two family reunions this weekend, but I am sure they will be a hit there as well. I did however, decrease the sugar by 1/4 cup, and I also peeled the zucchini and removed the seeds, since some people don’t care to see the green flecks of the peel… Love these….

    I love this recipe! I actually am on a restricted diet, so I can’t eat it. However, I love to bake and have made it twice for friends and family. I just entered a plate in the local fair and won first prize! I’m really digging these zucchini recipes. Thanks!

  10. This is my favorite brownie recipe! My husband won’t eat anything containing zucchini. Well, up until now! LOL And when I want to make my adult version of this recipe I just add crushed, dried Thai peppers. OMG. Yum.

      I love this recipe, I’ve made these brownies several times, and it’s a hit at work potlucks. I’ve substituted coconut flour, almond flour, and quinoa flour (sometimes a mix of all three, and even with regular, refined wheat flour). I think the consistency is closest to regular flour when using quinoa flour (although it’s somewhat hard to find and costs a lot more). Also I’ve had to keep it in the oven longer (10-25 minutes longer) when I used flour substitutes.

      Always delicious!

    These brownies are to die for they are so moist.  I made them last week and we loved them.  I took some to a friend and left the rest home and my husband couldn’t get over how moist they stayed for a couple days.
    They were absolutely the best brownies I ever made and no one knew they had Zucchini in them.  I am
    Making them again today for a coming home party and can’t wait to hear the reactions of the people.
    Thanks again.

    I just made these brownies for my mother-in-law’s birthday. They were a hit with my in-laws and my two kids ages 4 and 16 months. The brownies came out moist and the perfect amount of chocolate. I will definitely be making these again! Thanks!

    These are fudgey brownies and super tasty! I made a batch to share at work and everyone loved them. No eggs or milk made them safe for everyone to enjoy as well!

    Just made this recipe this morning. I used 1/2 cup applesauce with a tablespoon of oil in place of the 1/2 cup of oil. They are delicious! Even my husband (who said “did you put zucchini in those brownies???” with a not-so-happy face) loved them!

    These are the best brownies! I love the recipe as is! Sometimes I use 1 cup turbinado sugar in place of the granulated sugar and kosher salt. They almost taste like salted caramel brownies! Next time I will try applesauce in place of the oil. But you cannot go wrong with the recipe as is!

  16. Thank you for sharing these amazing brownies. For several years now this is my go-to brownie all summer long when the chickens give up laying eggs, and sneaky zucchini-monsters play hide and seek in the garden. Sometimes I add a little milk or water if the mix looks a bit dry, but generally using the electric beater (try the dough hook) smashes enough liquid out of the zuc. to bind it. I occasionally add berries or nuts or a dollop of peanut butter. They freeze beautifully for packed lunches.

    Delicious! I used applesauce because I didn’t have any oil. Will have to make these again since I ate most of this batch!

    I made these today and everyone loved them. I squeezed out extra water from the zucchini and I am glad I did as mine turned out very moist like a fudge brownie, not a cake style brownie. I used mini chocolate chips so I probably used more than was required of the regular size which I am sure helped them be more moist but nobody was turning them down. I also didn’t tell them about the zucchini until they ate one and the only response was asking for seconds!

    These are delicious but they fell apart when I tried to cut and remove from the pan. I will definitely add eggs next time I make these!
