Zucchini Pizza Casserole | Low Carb
This casserole. Sweet merciful. This Zucchini Pizza Casserole makes my life worth living. Low on the carbs, good on the butt, a little crispy cheese action going on, plus lots of pizza toppings. This dish has a cheesy zucchini crust, is topped with pizza sauce, more cheese, and any desired pizza toppings you choose.
I got this recipe from my husband’s cousin Karen {Hi Karen!} when we were living in Idaho going to school/Gord was going to school while I brought home the bacon. She lives in Idaho with her family and had us over for dinner several times. We love them. Anyways, one time she made this for our dinner and I fell in love. So, I got the recipe eons ago and only found it recently. Feel free to send her love mail because I know you’re all going to love this as much as we do.

I can hardly wait for my zucchinis to get big enough to eat. I want to make this recipe very much.
I am not a fan of Cheddar Cheese and I can only have small amounts of any cheese. This is the perfect type of recipe I love to make. I will review it afterwards.
We all loved this—and no one missed the bread. Absolutely delicious, will definitely make again. Added garlic powder to the zucchini mixture, because I look for any excuse to add garlic 🙃
I needed to bake this much longer than 20 minutes. It was close to 30!
Cool
I’ve made this several times and the Fam says it is truly a keeper! Anyone ever freeze it?
I thought you might be exaggerating about how good this is. Nope. It’s amazing! I put Canadian bacon, mushrooms and black olives for toppings. Yummy!!
Amazing, can’t believe how good this was. I often cook with zucchinnis, but hadn’t tried this one. Thanks for a very yummy recipe.
I make this at least once a month and my family LOVES it!!

I try to eat low carb as much as possible. I have tried many recipes for that pizza fix and have not found something I LOVED that I wanted to always make. But I don’t know if putting the word casserole on the end of the title changes what I anticipate eating, but this recipe is marvelous for me. It is one of my favorite recipes for lunch or any other time. It is perfect.
Just made this last night and I think my husband and I could have ate the entire pan. So good!!!
Wow, my kind of recipe! Looking forward to making it!
I just made this tonight. For my picky gluten free hubby. And we are both shoveling it down. I did an extra cup of zucchini just because I didn’t want to toss. Topped with black olives, sausage, onions, pepperoni, and I’m so surprised! Even the kids wanted to try it.
Thank you so much for the recipe
I want to try this! I’m hoping my family will overlook the zucchini crust and love the overall taste…fingers crossed!
I have made this twice this summer, and shared with many! It is so good. We make it in a jelly roll pan, use the yellow cheese in the crust and use all mozzarella cheese on top! I will be buying zucchini all winter and making this!

gonna make this, my husband only eats zucchini when i make it as a dessert, but pizza might give it a fighting chance! Keep those recipes coming, love trying new ideas
Hi Lauren,
Do you think it’d be possible to make and bake the base ahead of time, say the night before and keep in the fridge? Thinking I could then load it up and stick in the oven when I get the kids in from school as I only have about 20 mins til I head back out to work. Have you ever tried it?
