Ingredients Needed For Zucchini Pizza Casserole
I love making this in the summer with fresh zucchini out of my garden. Yummy! The rest is simple ingredients that you either have on hand or are easily found at your local grocery store. Here is what you’ll need to make Zucchini Pizza Casserole:
- Zucchini: Fresh zucchini is the star here, forming the base of the cheesy zucchini crust.
- Salt and Black Pepper: Adds flavor and helps to draw out excess moisture from the shredded zucchini.
- Large Eggs: Binds the zucchini mixture together.
- Mozzarella Cheese: Used in both the crust and on top—because you can never have too much cheese.
- Cheddar Cheese: Adds a sharp, rich flavor to the crust.
- Parmesan Cheese: For that classic Italian touch in the crust.
- Pizza Sauce: Your choice of marinara sauce or Italian tomato pizza sauce.
- Pepperoni Slices: Classic topping, but feel free to add your personal favorites.
- Fresh Basil: Adds a fresh, herbaceous note as a garnish.
Variations
- Cheeses: Swap cheddar for Monterey Jack or try part-skim mozzarella cheese for a lighter option.
- Toppings: Mix it up with cooked Italian sausage, black olives, bell peppers, onions, artichoke, spinach, mushrooms, or red pepper flakes.
- Crust: If you’re feeling adventurous, replace the zucchini with cauliflower for a different take.
- Protein: Try adding cooked shredded chicken, ground turkey, or brown ground beef for a heartier dish.
How To Make Zucchini Pizza Casserole
Throwing this dish together doesn’t take very much prep work! Simply grate the zucchini and cheeses, combine with egg and put it in a baking dish, and bake.

I just made this today for dinner tonight. It was extremely helpful to use the food processor to grate the zucchini.
Has anyone tried to freeze a portion after cooking? I’m wondering how well it reheats after freezing…
This looks so good. I long for the days when we grew zucchini. I’m planning on making zucchini bread soon so I will be buying extra to make this. By the way that would be a big fat no to the chocolate cinnamon bears, but ice cream is very difficult to turn away from. Thanks for the recipe. (Karen too)
I totally wan to try this but 4 cups grated zucchini = how many zucchinis?
Thanks!
what are the net carbs?
Perfect…a recipe to help use up the zucchini out in the garden!!!
Wow! This recipe is very inspiring, so many possibilities. There are like no carbs, so all that cheese is totally justifiable, more cheese please!

I made this tonight for dinner. It was a huge hit! We all loved it. Thanks for sharing this family recipe.
Holy cow moly. Y’all. This exceeded all expectations. We all wolfed it down like we hadn’t eaten in days. I wanted more. I wanted the whole dish….who are these other people eating in my house?! I put my zucchini in a tea towel and squeezed the liquid out. Ohhhhhhhhhhhhhhh my goodness. Make this. Yesterday. Right now. Who cares what time it is.

THANKS!
This looks and sounds SCRUMPTIOUS! JUST LOVELY! I will DEFINITELY be trying this soon!
This is also gluten-free.
Laura … this looks fantastic. I am trying to find foods that will help me maintain my weight while taking my medication for cancer (according to the doctor it will put as much as 50 or 75 pounds on you if not careful over the 5-year treatment period). I love food, so this makes meal time even more depressing when there are things on the table you shouldn’t eat.
Thanks so much for this recipe. I love veggie pizza .. now I can have one with no regrets …. even the WHOLE thing if i want.
I’m new to your blog, butI shall be following fro now on.
Thanks again,
Diana

Just made and ate this! It’s delicious! Even my picky daughter gobbled it up!!!!! THANK YOU!!!!
Holy smokes is this GOOD!!!! I wasn’t sure if I would like it so I cut everything in half. I’ve eaten three bites and already know I will be making this again. I had a package of broccoli slaw so used 2 cups of that. I had some jalapeno cheddar so I used that. I didn’t realize I didn’t have any Parmesan until too late. I used a single serving container of ranch dressing and a baked chicken breast I cut into pieces as the toppings (along with more cheese of course). WOW!!!! If my version is this good, I can only imagine how amazing it would be if I followed the recipe. Thank you for sharing such a wonderful recipe.

Thanks for sharing!!

Made this tonight – didn’t have chedder so I only used the mozzarella & parmesan. For the sauce I used some leftover roasted garlic spaghetti sauce from Trader Joes, and for the toppings some leftover diced chicken, sliced cherry tomatoes, olives, and sliced red onion. This was so, so delicious and was so much like pizza that we didn’t even miss the crust. Leftovers for lunch tomorrow! Thanks so much Lauren – another weeknight homerun!
Wow, Lauren, this looks amazing! Thank you for sharing.
Ok, that is a whole lot of deliciousness in a pan right there. That looks amazing!
I am going to try this soon!
Hey Lauren,
So, I just had this for dinner. I did only use one egg instead of two, tooooootally by mistake. Whoops. On top, I used spinach and feta sausage, red peppers, onions, and mushrooms (put olives on my husband’s half). Basically, it tasted like baked cheese. I mean, don’t get me wrong, I love cheese, but I didn’t taste the zucchini at all in the “crust.” Just cheese. It was also SUPER thin and flimsy. Any idea what I did wrong? Is it all because I forgot an egg?
I just made it as well and I also felt it tasted like just cheese, but my husband and kiddo were ok with that, lol.

I WILL be making this!! YUMMMMMMO
This is brilliant! My family will LOVE it!
Thanks Lauren! My husband loves pizza but is watching his carb intake, this should do the trick.
PS… Chocolate and cinnamon just shouldn’t go together in my opinion. I don’t even like it when it’s together in cookies. It’s just tastes odd to me.
nice share…
thanks
What a great idea, Lauren. That base can be used so many ways. 🙂
Holy crap, this is brilliant!
Great way to sneak in some greens! Love it!
Love this idea, what a unique way to use zucchini!
Looks sooo good! I am so making this tonight.
My husband loves chocoloate covered cinnamon bears, which I never even knew existed until I met him. I’m with you, its so confusing.
Um, WHOA. I actually thought this was a pizza in a baking dish at first. Zucchini “crust” totally fooled me! My parents just imparted the last of their zucchini bounty to me; I am soo making one tonight!!
A zucchini crust?! Now this I can get onboard with! I wasn’t really feeling the whole cauliflower-crust trend but I totally am feeling this!
That looks fantastic! I will have to try that with the garden bounty that has been coming in.
PS- Chocolate covered gummi bears = yum. Cinnamon bears = not so much.
PPS- I’ve had a box of Samoas in the pantry since March. I keep it there for JUST IN CASE there is a sweets emergency. You know, when I run out of chocolate chips, brownie mix, ice cream, Easter/Halloween stashes, etc. You are probably just being conservative for the sake of possible sweets emergencies. Wise planning.
This looks so yummy! I love easy casseroles, and any way to incorporate more veggies into my life is A-Okay with me 🙂
It’s a zucchini crust! So healthy!
By the way, no no to the chocolate covered cinnamon bears. >_<
Oh my gosh, this looks amazing!!!
If I would like to use mushrooms as a pizza topping, do I cook the mushrooms first before the final bake!
I didn’t and it turned out great. I used some pre-sliced white mushrooms and sometimes they are sliced a little thick so I gave them a few chops with a knife before I put them on.
How fun! I have made the cauliflower crust for pizza several times now. Brilliant to use zucchini
This looks amazing! Can’t wait to try it this weekend.
Lauren! This is a great way to use that zucchini I’m covered up with right now! Love it!
I’m totally digging this! Love the cheesy zucchini crust!
This looks delicious! Must try it soon.
Made this tonight. It was insanely delicious. The crust is slightly reminiscent chile rellenos because of the eggy-cheesy goodness.
I prepared the recipe x 1.5 and baked it in two 8 x 8 pans. One to eat and one to give to another (small) family. It worked out great. Thanks for this fantastic recipe! This is a new favorite!! 🙂
