Step-by-Step Instructions

Creating this Zucchini Ground Beef Casserole can be effortless by following these simple steps:
  1. Preheat Oven: Preheat your oven to 375°F (190°C).
  2. Cook Ground Beef: In a large skillet, heat olive oil over medium heat. Add the diced onion and garlic. Sauté until the onion is translucent, about 3 minutes. Next, add the ground beef and cook until browned. Drain any excess fat.
  3. Add Zucchini: Stir in the sliced zucchini and cook for an additional 5 minutes until they begin to soften.
  4. Add Tomatoes and Seasoning: Pour in the diced tomatoes (with juice), Italian seasoning, salt, and pepper. Mix well to combine and cook for another 5-7 minutes.
  5. Layer the Casserole: In a greased 9×13 inch baking dish, layer half of the meat and zucchini mixture. Sprinkle half of the mozzarella and cheddar cheese evenly over the top. Repeat the layers with the remaining meat mixture and cheese.
  6. Bake: Cover the dish with aluminum foil and bake in the preheated oven for 20 minutes. Then, remove the foil and bake for an additional 10-15 minutes, or until the cheese is bubbly and golden.
  7. Cool and Serve: Once done, remove from the oven and let it cool for 5-10 minutes before serving.
