Ingredients

Scale

Vegetables

  • 4 medium zucchinis, thinly sliced

Dairy

  • 1 1/2 cups grated Parmesan cheese

Sauce

  • 2 cups marinara sauce

Instructions

  1. Prepare the zucchini: Wash and thinly slice the zucchinis evenly to ensure even cooking and layering.
  2. Layer the ingredients: In a baking dish, spread a thin layer of marinara sauce on the bottom. Arrange a layer of zucchini slices over the sauce, then sprinkle a generous amount of grated Parmesan cheese. Repeat the layering process—marinara, zucchini, Parmesan—until all ingredients are used, finishing with a layer of Parmesan cheese on top.
  3. Bake the casserole: Preheat the oven to 375°F (190°C). Place the assembled casserole in the oven and bake for about 30-35 minutes, or until the zucchini is tender and the top is golden and bubbly.
  4. Serve: Allow the casserole to cool for a few minutes before serving to let the layers set and flavors meld together perfectly.

Notes

  • For extra flavor, sprinkle dried Italian herbs or fresh basil between the layers.
  • You can substitute Parmesan with Pecorino Romano or a blend of mozzarella for a creamier texture.
  • Use homemade or high-quality marinara sauce for best results.
  • Cover with foil during the first half of baking to prevent excessive browning, remove foil to crisp up the top.
  • This casserole can be prepared ahead of time and refrigerated before baking.
