Ingredients
Main Ingredients
Ground Turkey: 1 lb lean (or ground beef as substitute)
Zucchini: 2 medium, sliced into rounds or thin strips
Yellow Onion: 1 medium, diced
Garlic: 1 tablespoon minced
Olive Oil: 2 tablespoons
Sauce and Seasoning
Diced Tomatoes: 1 can (14 oz), drained or 2 cups tomato sauce
Dried Oregano: 1 teaspoon
Dried Basil: 1 teaspoon
Italian Seasoning: 1 teaspoon
Paprika: 1 teaspoon
Salt: 1½ teaspoons
Black Pepper: 1 teaspoon
Toppings and Texture
Mozzarella Cheese: ¾ cup, shredded
Parmesan Cheese: ¾ cup, grated
Italian-Style Panko Breadcrumbs: ½ cup
Fresh Parsley: for garnish
Instructions
Preheat your oven to 190°C (375°F) and lightly grease a baking dish.
Heat olive oil in a large pan over medium heat. Add diced onion and cook until softened. Stir in minced garlic and cook for another 30 seconds until fragrant.
Add ground turkey to the pan. Cook until browned and fully cooked through, breaking it apart as it cooks.
Season the turkey with salt, black pepper, paprika, oregano, basil, and Italian seasoning. Stir well to combine.
Add the diced tomatoes or tomato sauce and simmer for about 5 minutes so the flavors blend together.
In a separate pan or microwave, lightly sauté zucchini slices for 2 to 3 minutes just to soften slightly (this helps reduce excess moisture in the casserole).
In the baking dish, layer half the zucchini at the bottom. Spread half the turkey mixture over it.
Repeat with the remaining zucchini and turkey mixture to form layers.
Top evenly with mozzarella cheese, Parmesan cheese, and panko breadcrumbs.
Bake uncovered for 25 to 30 minutes, until the top is golden, bubbly, and slightly crispy.
Remove from oven and let it rest for 5 to 10 minutes before serving. Garnish with fresh parsley.
Tips
Sauté zucchini lightly first to avoid a watery casserole
Drain tomatoes well if using canned to prevent excess liquid

Let the casserole rest before cutting so it holds shape better
Add cheese in layers for more even melt and flavor
Do not skip breadcrumbs if you want a crispy topping
Taste the turkey mixture before baking to adjust seasoning
Use fresh garlic for stronger aroma and depth
Avoid overcooking zucchini so it doesn’t turn mushy
Bake uncovered for a golden top layer
