Now, let’s dive into creating this incredible Savory Ground Turkey Zucchini Casserole. Follow these simple steps:

1. Preheat Oven: Preheat your oven to 375°F (190°C) and grease a 9×13-inch casserole dish with cooking spray or oil.
2. Cook Turkey: In a large skillet, heat olive oil over medium heat. Add ground turkey, onion, and garlic. Sauté until the turkey is browned and cooked through, about 5-7 minutes.
3. Add Tomatoes and Spices: Stir in the drained diced tomatoes, Italian seasoning, salt, and black pepper. Mix well and simmer for an additional 2-3 minutes.
4. Layer Zucchini: In the greased casserole dish, begin layering half of the sliced zucchini on the bottom.
5. Add Turkey Mixture: Spread half of the turkey mixture over the zucchini.
6. Add Quinoa or Rice (Optional): If desired, sprinkle the cooked quinoa or rice over the turkey layer.
7. Repeat Layers: Layer the remaining zucchini slices on top, followed by the rest of the turkey mixture.
8. Top with Cheese: Sprinkle the shredded mozzarella cheese evenly over the top and then add the grated Parmesan cheese.
9. Bake: Cover the casserole dish with foil and bake in the preheated oven for 25 minutes. Remove the foil and bake for an additional 15 minutes, or until the cheese is bubbling and golden.
10. Cool and Serve: Allow the casserole to cool for about 5 minutes before serving.

These steps are easy to follow, making the preparation of your savory dish a breeze!
