Zucchini Casserole Recipe Ideas
When late summer arrives, everyone is always trying to figure out what to do with all of their zucchini. Overflowing gardens and farmers markets inspire home cooks and recipe creators. Zucchini recipes are everywhere as people are doing everything they can to put that veggie to good use.
I don’t know about you, but I actually love zucchini all year long. It is always available in the grocery store. Plus it is delicious, easy to cook, and super versatile, showing up in everything from pasta to pancakes to zucchini oatmeal. Not to mention it is nutritious.
What are the benefits of eating zucchini?
Zucchini is extremely low in calories and carbohydrates and naturally gluten free, making it healthy for anyone to eat, regardless of their diet or nutritional needs.
In fact, 1 cup of raw zucchini has only about 60 calories and 14 grams of carbohydrates, of which 8 grams are from fiber. This is why zoodles have become so popular! SOURCE
It is high in A and B vitamins and minerals like iron and calcium. Zucchini is rich in antioxidants, and it’s high water and fiber content make it great for digestion, blood sugar control, and heart health. SOURCE
And that is why I created this total hodge podge of a recipe that has become a family favorite. Basically I took some extra zucchini, leftover rice, and basics that I keep in my pantry and fridge. I just tossed it together, and was absolutely floored at how awesome it was. And now it is something we make regularly.
Because you can always use more zucchini recipes!

Frequently Asked Questions
How do you keep squash casserole from getting watery?
The key step is making sure you squeeze all of the moisture out of the zucchini. Also, since leftover rice is often a little dried out, it helps to absorb some of the excess moisture. This will ensure that you have a zucchini rice casserole that is moist and creamy, but not watery.
Is it OK to eat leftover rice?
There has been some concern about risks of food poisoning associated with leftover rice. However, as long as it it stored properly, it is safe to eat for up to several days after it is cooked.
First, avoid leaving it at room temperature for an extended length of time. Try to cool it quickly by dividing it into shallow containers before placing it in the refrigerator. Then be sure to reheat it to a high temperature before eating the leftovers.
Is this a gluten free casserole?
Yes, all of the ingredients in this recipe are naturally gluten free. Rice is also a gluten free grain that is safe to eat for those with celiac disease or gluten intolerance.

About how many cups of shredded zucchini is “2 medium” zucchini?
Brianne @ Cupcakes & Kale Chips says
I’m gonna be honest, I made this recipe quite awhile ago and don’t know. I’ve made it several times since, but honestly, now I usually just eyeball it, so I don’t think the recipe is super-sensitive.
Candace @ Cabot says
Love the recipe, love the name. Keep ’em coming!
Brianne Izzo says
Haha, thanks! 🙂
Sonya says
I made this about a week or so ago and it was a HUGE hit! I was panicking because I hadnt planned out our meals very well and only had two zucchini to work with! so happy I found your recipe..we loved it..thank you!
Brianne Izzo says
So glad to hear! Thanks for letting me know!
Cindys Recipes and Writings says
I love cheese and zucchini together. The rice adds a nice touch!
Brianne Izzo says
Yep, the rice makes it a bit more substantial of a side dish. And helps to hide the zucchini enough for The Big to eat it, since it is one of the few veggies he doesn’t like.
Anne @ Webicurean says
The Hodge Podge looks great! It’s almost a frittata, but you’d need a few more eggs for that 😉
Brianne Izzo says
Thanks Anne! Yes, I was thinking it was a little like a frittata, but I wanted the cheese and zucchini to stand out more, so I stuck with just one egg to bind it.
Family Foodie says
I love recipes using leftovers and I’m always looking for more. Hodge Podge is a great name for this dish and it looks delicious.
Brianne Izzo says
Whenever I can use up stuff in the fridge, I am happy. And the name credit totally goes to one of my Facebook followers.
Micha @ Cookin' Mimi says
The throw bits and bobs together recipes usually turn out to be fabulous and my favorites. How can you go wrong with rice, zucchini, and cheese?
Brianne Izzo says
Cheese makes everything better! 🙂
Laura Dembowski says
I don’t get Facebook at all. It just makes my head spin, but I totally get this awesome zucchini dish! Looks great!
Brianne Izzo says
Thanks! It was yummy!
Nancy @ gottagetbaked says
I know what you mean, Brianne. I have over 900 fans on my FB page but the most who have seen my posts are about 300 people. Usually it’s under 100. What’s up with that?! Rant away, lady. And I love this cheesy zucchini hodge podge. It’s always the simple, random recipes that end up tasting the best!
Brianne Izzo says
Ugh, Facebook is so annoying and I am having such a hard time getting into Google+.
DB-The Foodie Stuntman says
Call it whatever you like, it looks delicious
Brianne Izzo says

Wow, that looks delicious! I love how creamy and cheesy it sounds!

Creamy and cheesy without being overly rich! We loved it.
Christine (Cook the Story) says
I love this hodge podge idea. But more than that, I love how you handled explaining the FB thing to your readers. I’m going to do the same thing soon. I might even quote you! You said it perfectly and kindly and in a way that explained the problem. Well done!
Brianne Izzo says
Thanks, it has been frustrating me because I miss the interaction I used to have.
kathia Rodriguez says
Leftovers are perfect for a fast meal, It can be a blessing sometimes.
Brianne Izzo says
The other night when the hubby wasn’t home, the Bug and I ate little bits of everything (including the last of this dish) and called it dinner. It was perfect, and kept me from throwing stuff away.
Amy Kim (@kimchi_mom) says
I love a good hodge podge recipe! Yeah, FB has such a wonky algorithm going on that I stopped trying to figure it out a while ago!
Brianne Izzo says
Sometimes the random stuff you throw together is the best.
Sarah Reid, RHNC (@jo_jo_ba) says
I’ve eaten almost all of those ingredients together but never as a “bake”! Good idea
Brianne Izzo says
Thanks – I am so glad it worked, but I had a feeling those ingredients would bake together well.
The Wimpy Vegetarian says
Oh my. This is exactly what I want for dinner. And I have all the ingredients !!
Brianne Izzo says
It definitely is hearty enough to be dinner!
The Wimpy Vegetarian says
I’m just waiting for the rice to finish cooking. I added some onion and herbs because I had them around and wanting to be used. Can’t wait to eat it!
The Wimpy Vegetarian says
I wanted to let you know that I made it and just LOVED it. It was so, so good. My husband loved it too. We finished it off at breakfast 🙂 Definitely making again.
Brianne Izzo says
Oh I am so glad! Love your addition of herbs and onion. I only had enough time to toss it together and throw it in the oven, so I didn’t know if the onion would cook enough without sautéeing it first. But I bet it made it taste even better.
Debra Elliott says
Oh my… I love zucchini and this is sure to be a favorite yummy in my tummy delish dish…

This is the type of think my mom would make for us growing up. So simple and tasteful! The name is great, but don´t get me started on fb… not my favorite social media place, at all
Brianne Izzo says
I am trying to like G+, but I am just so comfortable on Facebook.
Jen @JuanitasCocina says
You call it hodge podge, I call it lunch please!
Brianne Izzo says
I know! I’m kinda wishing I had some left for lunch today.
Courtney @ Neighborfood says
Oh man, the Facebook thing is SO FRUSTRATING. I feel you! We’re all in this together. 🙂
On another note, I need as many zucchini recipes I can get. My zucchinis are coming in way faster than I can eat them. Thanks for sharing!

I know! It is such a pain. My reach had been increasing, then I had the baby and put things on hold.
