👩‍🍳 How to Make Ground Turkey Zucchini Casserole

Step 1: Preheat Oven

Preheat oven to 375°F (190°C). Lightly grease a baking dish.

Step 2: Cook the Turkey

In a large skillet, heat olive oil over medium heat. Add ground turkey, season with salt, pepper, paprika, and Italian seasoning. Cook until browned and fully cooked, about 6–8 minutes. Remove from heat.

Step 3: Sauté Aromatics

Add diced onion and garlic to the skillet. Sauté for 2–3 minutes until fragrant and softened. Combine with cooked turkey and stir in tomato sauce.

Step 4: Layer the Casserole

In the greased baking dish, layer zucchini slices on the bottom. Spread half of the turkey mixture over zucchini. Repeat layers, finishing with zucchini on top. Sprinkle mozzarella and Parmesan evenly over the top.

Step 5: Bake

Bake for 20–25 minutes until zucchini is tender and cheese is melted and golden.

Step 6: Serve

Garnish with fresh basil or parsley. Serve warm as a healthy, comforting main dish.
