Ingredients Notes

If you don’t have fresh herbs, dried ones work just fine. And don’t worry about making it gluten-free – simply swap the breadcrumbs for a gluten-free version.
Recipe Steps
Step 1
Preheat your oven to 375°F (190°C). Grease a baking dish with olive oil or non-stick spray to ensure easy cleanup later.
Step 2
Slice the zucchini and tomatoes into even rounds, about 1/4 inch thick. This uniformity helps them cook evenly.

Step 4
In a small bowl, mix breadcrumbs, grated parmesan cheese, and chopped herbs. Sprinkle this mixture evenly over the arranged vegetables for a golden, crispy crust.
Step 5
Bake in the preheated oven for 25-30 minutes, or until the vegetables are tender and the top is golden brown. Allow to cool slightly before serving.
Storage Options
To store leftovers, let the casserole cool completely before transferring it to an airtight container. It will last in the refrigerator for up to 3 days. For longer storage, you can freeze the casserole for up to 3 months. To reheat, thaw in the refrigerator overnight and bake at 350°F until warmed through, preserving that delicious, crispy topping.
Variations & Substitutions
If you’re catering to different dietary needs, try swapping cheese for a plant-based option to make it vegan. For a Mediterranean twist, add olives and feta cheese. Love spice? Sprinkle some chili flakes into the breadcrumb mixture for a warm kick. Tailor the recipe to your personal taste!
