Step-by-Step Cooking Instructions

1. Prepare the Vegetables
Start by washing and drying the zucchini and tomatoes. Using a sharp knife or a mandoline slicer, slice the zucchini and tomatoes into thin rounds, about ¼ inch thick. This ensures they cook evenly and layer beautifully in the baking dish. If the zucchini is particularly large, you might want to halve the slices so they’re easier to layer.
2. Preheat the Oven
Preheat your oven to 375°F (190°C). Lightly grease a 9x13-inch baking dish with olive oil or non-stick spray.
3. Layer the Vegetables
Begin layering the vegetables in the prepared baking dish. Start with a layer of zucchini slices, slightly overlapping them to cover the bottom of the dish. Next, add a layer of tomato slices, also overlapping them slightly. Sprinkle a little salt, pepper, and Italian seasoning over the layer. Add a portion of the minced garlic, a sprinkle of Parmesan cheese, and a bit of shredded mozzarella if using. Repeat the layering process—zucchini, tomatoes, seasoning, garlic, and cheese—until all the vegetables are used up. Make sure to finish with a generous layer of Parmesan on top.
4. Add the Topping (Optional)
For a crunchy topping, mix the bread crumbs with a tablespoon of olive oil and a bit of Parmesan cheese. Sprinkle this mixture evenly over the top layer of the bake. The bread crumbs will toast in the oven, adding a delightful crispy texture to the dish.
5. Bake the Dish
Place the assembled dish in the preheated oven and bake for 30-40 minutes, or until the vegetables are tender and the top is golden and bubbly. If the top is browning too quickly, you can cover the dish with foil during the last 10 minutes of baking.
6. Garnish and Serve
Once baked, remove the dish from the oven and let it cool for a few minutes. Garnish with freshly chopped basil or parsley before serving. This dish can be enjoyed warm or at room temperature, making it a versatile addition to any meal.

- Preheat the Oven: Set the oven to 375°F (190°C).
- Layer the Vegetables: Alternate layers of zucchini, tomatoes, garlic, and cheese in a baking dish.

Common Mistakes to Avoid
- Not Draining the Vegetables: Zucchini and tomatoes contain a lot of water, which can make the dish soggy. You can sprinkle the sliced vegetables with a little salt and let them sit for about 10 minutes, then blot them dry with paper towels before layering.
- Overcrowding the Dish: Avoid layering the vegetables too thickly, as this can cause uneven cooking. Stick to thin, even layers for the best results.
- Skipping the Seasoning: Properly seasoning each layer is key to a flavorful dish. Don’t forget to season with salt, pepper, and herbs as you go.
- Overcooking: Keep an eye on the bake to prevent the vegetables from becoming too mushy. They should be tender but still hold their shape.
