Preheat your oven to 375°F (190°C).

In a large skillet over medium heat, add the ground beef and brown for about 5-7 minutes.

Add chopped onions and minced garlic; sauté for about 3 minutes until onions are translucent.

Stir in the chopped zucchini and cook for another 5 minutes.

Pour in the tomato sauce and add spices; let simmer on low heat for 5 minutes.

Transfer the mixture to a greased baking dish, spreading it evenly.

Sprinkle cheese evenly over the casserole.

Bake for approximately 25 minutes until the cheese is bubbly and golden brown.

Let it cool for a few minutes before serving.
