Zucchini Tomato Casserole – Layers of baked Zucchini and Tomatoes coated with a creamy, cheesy blend and loaded with flavor! Serve it as a tasty appetizer, side dish, or a delicious vegetarian dinner.


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.

  1. This is really yummy. I tried to follow the recipe but did have to punt regarding the shredded Italian cheese and the cream sheets. I used a regular brick of softened cream cheese and as far as I can tell, that worked fine. For the shredded Italian cheeses, I made do with some string cheese thinking it would melt like mozzarella – it doesn’t, but it was fine. I’d like to try this again with some proper cheese though that melts hopefully before all the fresh garden tomatoes go away.

  2. Delicious summer harvest meal! Our guests asked for the recipe; the blend of herbs and cheeses really made it special. It is a keeper!

    1. Yep, that would be OK, too. Make sure to drain out the water that’s collected on the bottom of the baking dish, before you bake it.

    This was soooooo good. I added a 1/2 cup more italian blend cheese and doubled the fresh basil and sprinkled the top with italian seasoning. So good.

  4. Yum yum yum!! Made it for my keto vegetarian hubby and we LOVED it! I sliced the zucchini thin, salted, and pressed them to get out extra moisture and our bake came out soft and tender and ooey gooey. We wanted ours soft so we baked loosely covered for 30min and uncovered for 15 and yum! Thanks for the tasty recipe. ๐Ÿ™‚
