Ingredients

Scale

Main Ingredients

  • 1 pound ground beef
  • 3 medium zucchinis, sliced
  • 1 medium onion, diced
  • 2 cloves garlic, minced
  • 1 ½ cups tomato sauce
  • 1 ½ cups shredded cheese (such as mozzarella or cheddar)
  • 1 teaspoon salt
  • ½ teaspoon black pepper
  • 1 teaspoon Italian seasoning

Instructions

  1. Preheat Oven and Prepare Dish: Preheat your oven to 375°F (190°C) and grease a medium-sized casserole dish with cooking spray or a little oil to prevent sticking.
  2. Sauté Ground Beef, Onion, and Garlic: Heat a large skillet over medium-high heat. Add the ground beef and cook until browned, breaking it apart as it cooks. Add diced onion and minced garlic, sautéing until the onion becomes translucent and fragrant.
  3. Add Zucchini and Tomato Sauce: Stir in the sliced zucchini, tomato sauce, salt, pepper, and Italian seasoning. Cook for an additional 5 minutes, allowing the zucchini to soften slightly and the flavors to meld.
  4. Transfer to Casserole Dish: Pour the cooked mixture into the greased casserole dish, spreading it out evenly.
  5. Top with Shredded Cheese: Sprinkle the shredded cheese evenly over the top of the mixture to create a cheesy crust when baked.
  6. Bake Until Cheese is Melted and Bubbly: Place the casserole dish in the preheated oven and bake for 20-25 minutes, or until the cheese is fully melted, bubbly, and slightly golden.
  7. Serve Warm: Remove from the oven and let it cool slightly before serving warm to enjoy the rich flavors and comforting texture.

Notes

  • You can use any cheese of your preference, such as mozzarella, cheddar, or a blend of Italian cheeses for varied flavor.
  • For a lower-carb option, replace tomato sauce with a homemade marinara made from fresh tomatoes with no added sugar.
  • Adding some chopped bell peppers or mushrooms can enhance the vegetable component of the casserole.
  • Leftovers can be stored in the refrigerator for up to 3 days and reheated in the oven or microwave.
