Creating your Ground Turkey Zucchini Casserole can be a stress-free experience. Just follow these simple steps:

1. Preheat your oven: Set the oven to 350°F (175°C).
2. Prepare the vegetables: Wash the zucchini and slice them into half-moons. Chop the onion and mince the garlic.
3. Cook the turkey: In a large skillet over medium heat, add olive oil, then add the onion and garlic. Sauté until the onion becomes translucent.
4. Add ground turkey: Stir in the ground turkey. Cook until browned, making sure to break it apart with a spatula, about 6-8 minutes.
5. Combine the vegetables: Add the sliced zucchini and diced tomatoes to the skillet. Season with Italian seasoning, salt, and black pepper. Cook for about 5-7 minutes until zucchini is slightly tender.
6. Layer the casserole: In a greased 9×13 inch baking dish, layer half of the turkey and zucchini mixture. Sprinkle half of the mozzarella cheese on top.
7. Add remaining vegetables: Layer the rest of the turkey mixture and top with remaining mozzarella and Parmesan cheese.
8. Add cream (optional): If using cream, drizzle it over the top for extra creaminess.
9. Bake the casserole: Place the baking dish in the preheated oven. Bake for 35-40 minutes or until cheese is bubbly and golden brown.
10. Cool before serving: Remove from the oven and let it cool for 5-10 minutes before serving.

Following these steps will ensure that you create a delightful Ground Turkey Zucchini Casserole that is bursting with flavor and goodness.
