Corn & Zucchini Casserole
Corn & Zucchini Casserole – An easy cornbread casserole filled with corn and fresh zucchini makes a perfect side dish!

I’m so excited to bring you this recipe today. I shared it a few months ago on Mandy’s Recipe Box, and I couldn’t wait to do the same here. Corn Casserole has to be one of my favorite side dishes. It is so easy and so good, and it all starts with a box cornbread mix! Well, with zucchini season in full swing, I thought it would be a great addition to a family favorite. It’s moist, buttery perfection and a perfect summer side!
I often hear from readers who make their own cornbread mix. That would work fine here too! Just use your own recipe and add in the chopped onion, cream-style corn, and the shredded zucchini. Don’t forget the butter either!
Hope you enjoy this summer side as much as we did! See y’all next week, and be sure to check out other perfect side dishes below!

Just made this tonight and I have to say, this is amazing!! Such comfort food and such a great way to use excess zucchini from our garden. I made it exactly as the recipe stated and it turned out better than expected!

So awesome to hear, Susan! Thanks for letting me know!!!
I have made this a few times now and it is delicious.
Making it for Thanksgiving and would like to double the recipe in a larger pan. Just not sure if I should use double the butter melted in the pan? Anyone have any experience doing that that?
Hi MiMi! I would double the butter 🙂
I forgot to say in my previous comment that I add some whole kernel corn to this as well (in addition to the cream style). 1 can, drained or 3/4 – 1 cup frozen. I don’t really measure, just put some in. ☺️
This sounds delicious! I have added finely chopped, steamed broccoli to corn casserole before, but never thought about adding zucchini (or summer squash!). Definitely going on the list for summer when it squash season again.
Hi LizaJo! I’ll have to try adding broccoli next time! Sounds great!
Made this tonight but used less butter. It was awesome! Thanks for sharing.
So glad you gave it a try!
