Whether you’re looking to make the most of an abundant zucchini harvest or just want a healthy, flavorful side dish, this casserole is a wonderful addition to your dinner table.
The beauty of this casserole lies in its simplicity. Shredded zucchini is the star ingredient, offering a delicate texture that combines beautifully with eggs, cheese, and breadcrumbs to create a creamy, hearty dish.

What makes Shredded Zucchini Casserole even better is its versatility. You can easily customize the flavors by adding herbs like garlic, basil, or thyme, or even throw in a bit of onion or bell peppers for extra depth. The cheese can vary too – try sharp cheddar for a bold flavor or mozzarella for a creamy, melty finish. For a touch of crunch, top the casserole with a sprinkle of Parmesan or a few extra breadcrumbs before baking.
This dish is not only delicious but also relatively light, making it a great choice for those seeking a healthier comfort food. It’s perfect as a side dish for grilled meats, roasted chicken, or even as a vegetarian main course. Plus, it’s easy to prepare ahead of time and reheats well, making it a convenient option for meal prepping or feeding a crowd.

Made this for dinner last night, everyone gobbled it up! Definitely making again!
I dunno, mine turned out mushy last time…maybe I added too much zucchini?
That’s awesome to hear! It’s such a simple yet delicious dish! What did you serve it with?
This was an awesome recipe! My family loved it! 😊
Zucchini is just a sponge for flavors!! 10/10 would recommend. Best veggie!
I tried it but it was too watery, maybe I needed to squeeze the zucchini more?
Just a bunch of green stuff, I don’t like it. Yuck! 🤢
Really don’t see the fuss over zucchini. This dish was just okay for me. 😒
Zucchini? Is that the green one?? My kids won’t eat this! No way! 🤷♂️
Zucchini? Yuk! I only tried it because my friend made it and I couldn’t say no, but I won’t make it myself. Just my opinion!
Meh. I thought it would be more flavorful. Needs more cheese, I think.
I actually found it quite tasty! Maybe try adding a sprinkle of parmesan on top for extra flavor next time.
More cheese? I think it has plenty already. Just try eating it with a cheesy side dish!
I dont like zucchini much, but this casserole was actually pretty good. Surprised me!
So easy to make, even my kids helped! They had fun shredding the zucchini.
I dunno… it seemed bland to me. Is the onion enough?
This is the best zucchini casserole I have ever made! So cheesy and delicious! 👍
I wasn’t sure about using zucchini like this, but it turned out great. I added some spices.
Zucchini casserole? More like a nightmare casserole lol.
Tried this and it was soggy… did I do something wrong? I followed the recipe.
Simples and good. Next time I will add some tomatoe and spice it up a bit. 😊
I substituted the zucchini for broccoli and it turned out awesome! Just saying!
Zucchini? Really? I ain’t tryin’ no green squishy stuff. No thank you.
Green squishy stuff? That’s a bit harsh! Zucchini is basically a vegetable superstar! 🙃
I used to think like you, but trust me, zucchini can be so good! You just gotta find the right recipe. Give it a chance!
This turned out great! The flavor is amazing, and my family loved it. Definitely a keeper!
Delicious! I added some spices like paprika and it was 🔥
This sounds delicious! Can’t wait to try it out. Love zucchini!
Looks good, but is it really that easy? My casseroles never turn out right.
Yum! Zucchini’s the best! Let me know how it turns out!
This was a hit at my dinner! Everyone loved it! Will definitely make again.
Super easy and I had everything on hand. I squeezed the zucchini dry like the internet says and it turned out great—no puddle!
so easy to prepare! i added some spices and it was great!!!!
I’m glad you enjoyed it! What spices did you add? I’m always looking to improve recipes.
Yummm! Perfect side dish and healthy too! 👍
Do I really need to add the eggs? Can it be vegan?
I don’t think I did it right. Mine came out soggy and undercooked.
Made this tonight—so good! The zucchini stayed moist and the cheese flavor really came through. I added a pinch of paprika and it was perfect.
Wait… 375°F for 40 minutes and it gets golden? I think my oven runs hot, because mine browned way too fast around 25 minutes and the middle wasn’t set. I had to tent with foil and keep baking. Still yummy, just need timing tweaks.
Super easy to make, but I think I added too much garlic. Next time I’ll tone it down a notch.
Way too much onion for my taste. I barely tasted the zucchini!
I followed the recipe exactly and mine came out a little watery. Maybe my zucchini was too wet? Still tasted nice though.
Yeah, zucchini can be SUPER watery—especially if it’s not squeezed/dried. Next time, try salting the shredded zucchini and letting it sit, then squeeze out the liquid. Also, baking until it’s fully set (sometimes a few extra minutes) helps a lot. Glad it still tasted nice though!
What a great way to use up all that zucchini from my garden! Yum!
I don’t know, something just felt off with the taste. Maybe too much garlic? 🤔
Simple, but just ok. I think it needed more spices or something. Maybe garlic powder?
I don’t understand why you’d mix cheese and zucchini. Sounds weird.
I followed the recipe but came out mushy. Maybe I squeezed the zucchini too much? I dunno.
Tried this, and it was soooo good! I added some ground beef for protein. Yummy in my tummy!
I’m not too sure about this. I mean, zucchini? I usually just steam it. Baking it seems weird.
I thought the same at first! But trust me, baking brings out a unique flavor in zucchini. You might love it!
Weird? Nah, just different! I tried it and it’s actually pretty good! Give it a shot!
Delicious! Perfect for summer veggies. I used mozzarella instead of cheddar.
Using mozzarella sounds like a great twist! I’ll try that next time. Thanks for the tip!
This turned out so good—comfort-food vibes but still feels lighter with all that zucchini. I added a pinch of paprika too and it made the whole thing taste more “done.” 40 minutes was perfect for my oven.
The casserole was burnt on the edges and gooey in the middle. Not worth it.
I accidentally used 3 cups of chopped zucchini not shredded 😅 but it still worked. I baked it a few extra minutes and it browned nicely.
Yum! Perfect dish for using up my garden zucchinis. Will make again!
Zucchini’s are gross, why would you even make this?
I made this and it was just meh…needed more flavor, I guess?
Only 40 minutes?? Mine took like an hour to set. Maybe my oven runs cold. Tasted good once it finally firmed up.
I mixed up the flour and forgot the salt…oops! Still ate it tho.
Who knew zucchini could be so good? I’m making this again for sure!
Yummy, but I used way too much garlic I think. Haha!
Garlic’s the best! A little extra can make things more flavorful! Just might need some mints after, haha!
This was a hit at dinner! My kids loved it!
So glad to hear that! My kids loved it too! It’s a great way to sneak in veggies.
So easy to make! Even my kids loved it. Will make again!
Yasss! Zucchini for the win! 🥒 I will make this for every potluck now!
Pretty good, but my casserole took closer to 50 minutes to set. Also squeezed the zucchini a bit next time because it seemed a tiny soggy. Still tasty though.
This is a game changer for my summer zucchini! Loved it!
I’m glad you loved it! Zucchini is so versatile; it really shines in this dish! 🍽️
Just made it, it smelled great while cooking! 🍽️
This is just like my mom used to make, brings back memories. 😊
I love that! My grandma used to make something similar too. Comfort food at its best! ❤️
Not bad, but I’m not sure about the flour amount. Mine turned out a bit dense, like an eggy loaf. Flavor was fine—cheddar and garlic carried it.
I think your flour was off somehow, or your zucchini was way wetter than average. Mine came out kinda like a frittata, but not dense. Next time try 1/3 cup flour or bake 5–10 min longer so it firms up.
Good catch. With zucchini, the moisture can really throw off the texture—if the zucchini isn’t well drained, it can go dense and “eggy.” I usually squeeze the shredded zucchini in a towel first and only use 1/4 cup flour as written. Also, letting it rest a few extra minutes helps it set.
Honestly I don’t get the hype. The texture is fine, but it’s missing that “wow” factor. Could’ve used more cheese.
I get where you’re coming from—this one is more “comfort casserole” than big wow. If you’re a cheese person, I’d honestly bump it up next time (extra cheddar or even a mix like mozzarella).
