Prep time


Cooking time




  • 1 1/2 cups grated Cheddar cheese

  • 1/3 cup grated Parmesan cheese

  • 1/2 teaspoon dried oregano

  • 1/2 teaspoon dried basil

  • 2 cloves garlic, minced

  • salt and pepper to taste

  • 2 medium zucchinis, thinly sliced

  • 5 plum tomatoes, thinly sliced

  • 1/4 cup butter

  • 2 tablespoons finely chopped onion

  • 3/4 cup fine bread crumbs


  • Preheat oven to 375 degrees F (190 degrees C). Lightly butter a 9×9-inch pan.
  • In a large bowl, combine Cheddar, Parmesan, oregano, basil, and garlic. Season with salt and pepper, and set aside.
  • Arrange half of the zucchini slices in the pan. Sprinkle 1/4 of the cheese and herb mixture on top. Arrange half of the tomatoes, and top with another 1/4 of the cheese mixture. Repeat layers.
  • Melt butter in a skillet over medium heat. Stir in onions, and cook until soft and translucent. Stir in breadcrumbs; cook until they have absorbed the butter. Sprinkle on top of casserole.
  • Cover loosely with foil, and bake in a preheated oven for 25 minutes. Remove foil, and bake until the top is crusty and the vegetables are tender, about 20 minutes.
