Having a low-carb, healthy side dish like this is the perfect addition to this amazing grilled Italian chicken or your favorite fish and it’s always a crowd-pleaser.
When I say this is easy, I mean really easy. All you have to do is slice and layer zucchini, yellow squash, tomatoes and onions in a casserole dish, sprinkle with the light seasoned crunchy topping, then bake in the oven.
It’s a wonderful way to get a rainbow of fresh vegetables into your meal. I have also made it with thinly sliced potatoes as well but that does up the carbs more.
This is one of those casseroles that doesn’t freeze well in my opinion. Zucchini has a tendency to hold water so freezing it may make it turn out mushier.
Also, if you prefer your vegetables more al dente, just reduce the cooking time and cook for only 15-20 minutes.

When struggling with carbs and what to eat because of blood sugar issues this is a great idea. I am tired of avoiding everything and finding nothing good to eat that does not violate my sugar/carb count.
This zucchini casserole looks so delicious layered with tomatoes, panko and parm! Pinning to try soon.
Can you substitute other veggies for the one listed? Such as cucumbers, green peppers, etc.
Definitely can make it with what you’d like 🙂
5 stars for being 65 calories! My kind of dish!
Can’t wait to try this, looks yummy and simple. And healthy, thanks!
This was amazing and so easy! Big hit at Easter dinner!
Nice looking recipe, but I don’t understand direction #3. Place what sliced one on the bottom?
I think I’ll try this anyway, it’s not rocket science.
Oh gosh! that should say “onion”! Thanks for letting me know!
My squash is starting to come in. I will definitely be giving this a try! Thanks so much for sharing with Let’s Get Real. Pinning to our group board.
Why does it say 65k cal? Is it 65 calories total or are we saying it’s 65,000 calories for the whole casserole. I wouldn’t think it would be that much. I’m just confused by the k.
One kcal is the same measurement as one calorie. For some reason that is the one used by the nutrition calculator.
I love the combination of summer veggies for this great bake! Thanks so much for sharing your awesome recipe with Full Plate Thursday. Hope you are having a great week and come back soon!

This looks amazing! I am doing weight watchers right now, so this looks like it will be low on the points! Thanks!
It is such a great “Light” side dish! I am planing on making it for a Memorial Day Picnic. 🙂
Sounds delicious! Thanks for the recipe.
Can’t wait to try your recipe! I’ve made something similar but yours looks way healthier & easy!! Michelle

Yum! I can’t wait to try this! We actually have all three of those veggies growing right now. I love that you made it without the potatoes, it seems like a lighter side dish. You’re right, it would totally compliment grilled chicken! Thanks for sharing the recipe and linking up to What’d You Do This Weekend. Pinned and scheduled to share on FB 🙂
