1. Preheat your oven to 375°F (190°C).

2. Heat a large skillet over medium-high heat. Add the ground turkey and cook, breaking it apart with a spoon, until no longer pink. Drain any excess fat.

3. Stir in the chopped onion and minced garlic. Cook for 3-5 minutes, until the onion softens.

4. Add the shredded zucchini to the skillet. Cook for another 5-7 minutes, stirring occasionally, until the zucchini softens and releases its moisture.

5. Pour in the diced tomatoes (undrained) and tomato paste. Add the Italian seasoning, salt, and black pepper. Stir everything well to combine. Simmer for 5 minutes, allowing the flavors to meld for this ground turkey zucchini casserole.

6. Transfer the turkey and zucchini mixture to a 9×13-inch baking dish.

7. Evenly sprinkle the shredded cheddar cheese over the top, then follow with the mozzarella cheese.

8. Bake for 20-25 minutes, or until the cheese is melted, bubbly, and slightly golden.

9. Garnish with fresh parsley before serving. Enjoy your Easy Low Carb Ground Turkey Zucchini Casserole!
