This Zucchini Tomato Bake is a delicious way to use summer produce. The flavor combination of zucchini, tomatoes, onions, Parmesan and seasonings is absolutely amazing! Serve it as a side dish or over rice for a satisfying vegetarian meal.
My little summer garden is thriving and I’m so excited to be sharing one of my favorite veggie side dishes that I make with my harvest! This zucchini dish is a perfect accompaniment to just about any main course and couldn’t be easier to prepare.
Ingredients Notes
- You’ll need 4 to 5 small zucchini (about 2 pounds) – ends cut off and sliced into ¼ inch rounds.
- Cherry or grape tomatoes – sliced in half. You can also use chopped tomatoes.
- I enjoy the flavor of yellow onion in this recipe. Please note that the chopped onions are not completely soft when this dish comes out of the oven, they’re more of a crisp-tender texture. Feel free to omit the onions, if desired.
- Salt and black pepper – adjust the amounts to your liking.
- Parmesan cheese – finely shredded. You can also use shredded mozzarella or Italian blend shredded cheese.
- Minced fresh garlic – garlic powder can be substituted.
- I love the convenience of using Italian seasoning, but if you don’t have it on-hand, fee free to use a combination of dried basil, oregano, thyme and/or rosemary (or whatever dried herb(s) you think would be delicious!).
How to Make Zucchini Tomato Bake
- Combine all ingredients (reserve ¼ cup of the Parmesan cheese for topping) in a large bowl.
- Transfer to a baking dish that has been sprayed with cooking spray.
- Sprinkle with the reserved Parmesan cheese. Bake for 30 to 35 minutes, or until desired tenderness of the zucchini is met.
Enjoy!

I had to boost the temperature to 375 to get the squash to cook at all here at 5400 feet. Yummy result once I figured that out. I used random tomatoes without issue.
patrice
can i use beefsteak tomatoes? that is all i hvve
Amy @ The Blond Cook
Hey Patrice, I’ve never used beefsteak tomatoes in this recipe so I can’t say with certainty. Let us know if you try it! 🙂
Gladys Lopez
Amy, I was looking to make a quick yet tasty veggie dish and made this dish for a group of six. It was visually pretty to look at and tasted great. Needless to say it was all gone before I knew it. I look forward to making this on a regular basis and thank you for sharing it.
Amy @ The Blond Cook
Thanks, Gladys… happy to hear everyone enjoyed it! Happy New Year! 🙂
Joan
I liked the idea of this recipe and made it tonight. But——at 35 min, not cooked, added 8 minutes, still not cooked enough(onions crunchy) about to check after another 8 minutes. Success, now cooked, but it took~50 min in a recently calibrated electric oven
Amy @ The Blond Cook
Hi Joan, sorry that happened… I baked this is a newer oven less than a year old when I made it and timed the bake time. I do know that different altitudes affect baking time and mostly every oven cooks differently so hopefully that’s what it was. Hope you enjoyed it, though! 🙂
Broccoli Rob
This is excellent. Only things different i did was use Mexican 4 cheese from Tillamook, fresh rosemary and oregano instead of the italian seasoning, and pecorino romano instead of parmesan. thanks!
Amy @ The Blond Cook
Your version sounds delicious, Rob! Thanks so much… so glad you enjoyed it! 🙂
Vicki Leahy
Could this be done in a slow cooker?
Amy @ The Blond Cook
Hi Vicki, I’m not sure because I’ve never made this recipe in a slow cooker… if you try it, please let me know how it works for you! 🙂
Annie
Can you prepare this the day before you plan to cook it?
Annie
Amy @ The Blond Cook
Hi Annie, I would not recommend preparing this ahead of time, but preparing it right before you plan to bake it. Hope you enjoy!
Lenore
How many would this serve?
Amy @ The Blond Cook
Hi Lenore, this serves 4-6. Hope you enjoy! 🙂
Anne heard
No olive oil or anything??
Amy @ The Blond Cook
Hi Anne, no olive oil. The juices released from the veggies while baking (and the cheese) prevent it from being dry. Hope you enjoy! 🙂
Amanda
What size baking dish should’ve used?
Amy @ The Blond Cook
I used a round casserole dish but a 9 x 13 baking dish should be sufficient. Hope you enjoy! 🙂
Sheila
Could green tomatoes be used in this recipe?
Amy @ The Blond Cook
Hi Sheila, I’ve never made it with green tomatoes so can’t say… I wouldn’t think so but then again I’ve never made it that way. Hope you enjoy it if you make it! 🙂
