Step-by-Step Instructions
- Preheat the oven to 375°F (190°C). Lightly grease a medium baking dish with olive oil or cooking spray.
- Cook the turkey: Heat olive oil in a large skillet over medium heat. Add ground turkey and cook for 5–6 minutes, breaking it apart with a spoon until no longer pink.

- Add tomatoes: Pour in the drained diced tomatoes. Simmer for 3–4 minutes until most liquid evaporates.
- Mix in creaminess: Turn off the heat and stir in sour cream (or yogurt) and half of the mozzarella cheese.
- Assemble: Spoon mixture evenly into the prepared baking dish. Sprinkle the top with the remaining mozzarella and all the Parmesan cheese.
- Bake: Place in the oven for 20–25 minutes, until bubbly and golden brown on top.
- Rest and serve: Let it cool slightly before serving. Garnish with a sprinkle of fresh basil if desired.
Pro Tips for Success
