This creamy and savory Zucchini Tomato Casserole is so incredibly simple to make and it’s the perfect way to enjoy your garden’s summer veggies. Throw this in the oven, and 30 minutes later you’ll have a DELICIOUS side, or meal, to enjoy with your family. Or alone! My husband did… 😏 

Do you have a garden? I have been gardening together with my parents for the past 7 years – my dad prepares the soil, my mom and I plant –  and I can’t describe the amount of excitement and pride that I feel when I see results.

Take for instance this Zucchini Tomato Bake – the zucchinis and tomatoes in this dish all came from our vegetable garden. But, the tomatoes…ohhhh the tomatoes…wow!

Layers of zucchini slices and tomato slices topped with garlic.

To say that they are delicious would be an understatement. Juicy, yet firm, sweet, yet tangy. The perfect balance.

If you don’t like tomatoes, please hop on over to our recipe for Cheesy Zucchini Casserole – it’s really good! 

To add, you know you’ve got something good when you all run to the garden, pick a vegetable and eat it right there and then. No washing, cutting, plating.

What’s better is when you prepare something with those vegetables and there are no leftovers. This zucchini casserole was polished off in one sitting. 


I’ve come to realize that if I want this family to enjoy veggies more often, I must pair those veggies with cheese. Whatever works, eh?

  • We start with slicing up around 2 average-sized zucchinis and two large heirloom tomatoes. Slices of both veggies should be around 1/4-inch thick.
  • In a 9-inch baking dish layer the zucchini slices and then the tomato slices. In between each layer, sprinkle the tomatoes with fresh basil and garlic. Sprinkle the zucchini with salt and fresh ground pepper.
  • Combine cream cheese and milk in a bowl and whisk in a pinch of nutmeg, and Italian Seasoning. Add a layer of the cream cheese mixture over the tomatoes and sprinkle with shredded Italian blend cheese or mozzarella cheese. You can use whatever type of shredded cheese you have on hand.
  • Continue with one more layer of zucchini and lastly a layer of tomatoes. Spread the remaining layer of cream cheese mixture and add more cheese.
  • Bake for 25 minutes, or until bubbly, browned, and veggies are tender.
  • Let stand 10 minutes in room temperature.
  • Cut and serve.

This low carb and Keto-friendly Zucchini Tomato Casserole is an easy way to use up and enjoy summer vegetables. Fresh and full of flavor – this is one very delicious and light summer dish. 


  • Zucchini and tomatoes will release water during baking and that’s completely normal. 
  • If you don’t want to bother with adding salt, pepper, garlic, and basil in between layers, you can just mix them in with the cream cheese blend. 
  • For those that like a softer veggie, keep the dish in the oven for an extra 7 to 10 minutes. If you see that it’s browning too much on the top while baking, please loosely cover with foil while continuing to bake. 
  • Serve this casserole with grilled meat or chicken for a complete meal, or enjoy as a vegetarian dinner.

  • Store in airtight containers and keep in the fridge for up to 3 days. Makes for a delicious and quick work lunch! 


  •  I don’t recommend it because zucchini and tomatoes both release a lot of water and that will affect the taste and texture of the overall dish.

    My son doesn’t like cream cheese. Is it obvious after it’s cooked? He’s sometimes ok if you can’t tell it’s in there after it’s done. Is there something else I could use?

    1. Katerina Petrovska

      I haven’t tested this with anything other than cream cheese, but maybe you can try to make it with sour cream or plain yogurt.

    1. Barbara

      That’s the way I’m going to do it. Were you a Tyndall AFB in 1973? Can’t be tooo many Bill Smiths out there!

    1. Rosalind Paragus

      Terrible- i used a mandolin to slice zucchini- came out hard. Not impressed with this at all. Flavor-eh

  2. Tina

    Wow! This was fantastic! I didn’t have a problem with excess fluid as others mentioned but I used one of my over grown zucchini’s which was perfect. The only problem was that we all over ate! 😂

  3. Greta H

    The flavor was really incredible. I cooked it in a deep oval casserole dish and 25 min was not enough. Next time I’ll either cook it longer or use a shallower dish to distribute the layers. Thanks for the recipe!

  4. Helen

    One of the best things I have ever eaten! Thank you so much for sharing your fabulous recipe. I was able to use fresh garden tomatoes and zucchini.

    1. Linda

      Delish! I added heavy cream to cream cheese and added my garlic to this mixture. Thank you for great recipe‼️

  5. Leslie

    waaaaaaaaay too watery, sauce became a gross, grainy, clotty mess as it cooled. Leftovers (there were lots) went in the bin as I couldn’t imagine a way to salvage them. What a waste of perfectly lovely summer produce. This was a big miss.

  6. Jean

    What a delicious casserole! Made this tonight with zucchini, tomatoes and basil from my garden, I only had an 8oz. block of cream cheese so I used that and used 2 teaspoons of chopped fresh basil instead of dried. After baking and letting it sit a few minutes, I poured some of the liquid out of the pyrex dish. Just a wonderful flavor of the fresh vegetables and cheeses. I will be making this a lot, thanks for the recipe😊

    1. Lizzzzzie

      Of course! I actually did the same thing and it turned out great! But definitely don’t put in freezer for a second time… downs leave a great taste in your mouth after being frozen twice! Haha heheh!

    I love your recipes but I can hardly see them with all the dang ads. It is so annoying to maneuver around. Are there printable versions that we can pay for that don’t contain ads??

    1. Katerina Petrovska

      There’s a “Jump To Recipe” button at the top of every post; just click on that and it will automatically scroll you down to the recipe card. That should help you with seeing the least amount of ads. Unfortunately, we can’t run websites without ads; it costs far too much to do this without any compensation.

    Totally loved it!!! I had a little goat cheese in the fridge, which I added and put Romano in with the crumbs. So quick and easy!! We all gobbled it up!!!

    I’m jealous of your family garden! It’s a wonderful way to teach children about food we eat too. I live next to the canyon where we have wild animals who eat our plants! So gardening is like a dream to me. It must be so nice to use your own veggies to make this delicious food. The flavor is simple, not over killing the ingredients that you can appreciate the natural flavor. Love this recipe!

  10. Liz

    I’m so jealous of your garden, Kate! I have not gotten my usual tomato donations from friends this year due to the drought :/ Nothing better than delicious garden tomatoes and your casserole looks fantastic~

    1. Kate@Diethood

      Liz, I can probably count how many tomatoes we had in total … this drought killed everyone’s garden 🙁

  11. Kate

    This is beautiful! Great seasonal dish and I just adore those plates. I should really invest in some pretty plates. They’re captivating.

  12. Amy @ fragrantvanillacake

    This sounds delicious Kate! Tomatoes and zucchini are so wonderful this time of the year I try to eat as much as I can! Love the simplicity of this, my Mom used to make something similar and it was always a hit :)!

  13. Zoe

    Greetings from Australia!

    Totally agree with you that gardening is so rewarding. We get fresh foods and lots of family time together. Funny that we are expecting the Spring in a few weeks time and we are sowing zucchini and tomatoes seeds soon. This recipe will waiting for me to cook when our garden is ready for harvest during Xmas 😀

  14. Sommer@ASpicyPerspective

    Mmmm, perfect for the loads of tomatoes and squash I have coming out of the garden right now!

  15. Kristy

    I just love your pictures. They always make me so hungry! The plate is gorgeous too. And this dish is one that we would certainly enjoy. The bread crumbs were a great idea!
