A lot of us have been inspired to plant home vegetable gardens. If you’re like me, chances are you’ve included zucchini, maybe yellow squash, and tomatoes to your list of must-have veggies. Not only are they nutritious and easy to use in so many recipes – they also tend to grow in abundance! Ever run out of ideas how to use them? This recipe is perfect for showcasing the goodness of these great veggies!
Of course, you don’t need a home garden to create this dish. Pick up some zucchini, yellow squash & tomatoes at your local farmers market or grocery store and you’ll have practically everything you need to make this recipe.
This easy garden zucchini squash casserole is similar to a traditional French Ratatouille – a stewed vegetable dish which often includes eggplant, bell peppers, crushed tomatoes and herbs. This recipe is a simplified version – celebrating the flavors and textures of the squash and tomatoes.
What goes into a garden zucchini squash casserole?
This is such a simple dish to put together, but it looks so gorgeous, you would think you spent a lot of time preparing it!
Here’s all you’ll need:
- 2- 3 medium size zucchini
- 2-3 medium yellow squash

- 2 tbsp extra virgin olive oil – (omit for oil-free)

How to make a garden zucchini squash casserole
- Preheat oven to 400º
- Thoroughly wash zucchini, yellow squash, and tomatoes.
- Slice in thin rounds (about 1/3″ thick)
- Pour a small amount of olive oil in the bottom of a medium size or 7″ x 11″ baking dish. Spread around to coat bottom of dish.
- Begin stacking the veggies on end, in rows, staggering the colors. I find it easiest to tip the dish slightly on end while layering.
- Next, drizzle a small amount of olive oil over the veggies.
- Sprinkle with salt and pepper and Italian seasoning.
- Cover top of veggies with Italian Panko breadcrumbs. You can add vegan parmesan if you like . . . check out this easy recipe!
- Cover pan with foil. I prefer to place a layer of parchment paper between the food and the foil.
- Bake at 400º for 20 minutes. Remove foil/parchment and continue baking for 10 minutes, or until breadcrumbs turn golden brown and juice is bubbling in the bottom of the dish.
- Allow casserole to sit 5 – 10 minutes before serving. Sprinkle fresh basil over top.
This recipe makes a perfect side dish to serve with:
