How to Make Zucchini Parmesan

  1. Preparation: Preheat your oven to 325°F (165°C).
  2. Cook Zucchini: Bring a large pot of water to a boil. Add thinly sliced zucchini and cook until tender. Drain well.
  3. Sauté Vegetables: Heat 2 tablespoons of olive oil in a medium skillet over medium heat. Add 1 diced large onion and 2 minced garlic cloves. Cook until the onion is tender, about 2 minutes.
  4. Assemble Casserole: Combine the cooked zucchini, sautéed onion, and garlic in a 9×12-inch casserole dish. Pour a 16-ounce jar of marinara sauce on top and stir well. Top with 1 cup of shredded mozzarella cheese (or more, to taste).
  5. Bake: Place the casserole dish in the preheated oven and bake until the zucchini slices are heated through and the cheese is bubbly, about 20 minutes.

How to Serve Zucchini Parmesan

Serve this dish hot and fresh out of the oven. It pairs wonderfully with a crisp green salad or garlic bread for a complete meal. For an extra touch of flavor, sprinkle some freshly grated Parmesan cheese or chopped basil over the top just before serving.

How to Store Zucchini Parmesan

Store any leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, place the desired portion in a microwave-safe dish and heat until warmed through. Alternatively, reheat in the oven at 325°F (165°C) until hot and bubbly.
