Ingredients
  

  • 3 medium zucchini, sliced2 cups marinara sauce
  • 2 cups marinara sauce
  • 2 cups shredded mozzarella
  • 1/2 cup grated Parmesan
  • 1/2 cup breadcrumbs
  • 1 tbsp olive oil
  • 1 tsp Italian seasoning

Instructions
 

  • Preheat the oven to 375°F (190°C), lightly grease a baking dish, and sprinkle the sliced zucchini with a small amount of salt.
  • Let the zucchini sit for about 10 minutes, then blot both sides thoroughly with paper towels to remove released moisture.
  • Spread a thin layer of marinara sauce across the bottom of the prepared baking dish and arrange a layer of zucchini slices over it.
  • Add more marinara, a portion of mozzarella, and some Parmesan, then repeat the layers until all ingredients are used.
  • Combine the breadcrumbs with olive oil and Italian seasoning, then sprinkle the mixture evenly over the final cheese layer.
  • Bake uncovered for 30–35 minutes until the casserole is bubbling and the breadcrumb topping is deeply golden.
  • Allow the dish to rest for 8–10 minutes before slicing so the layers hold together more cleanly.
