Preheat oven to 400°F. Mix turkey, breadcrumbs, 1/2 cup Parmesan, 2 eggs, parsley, garlic, 1 teaspoon salt, 1/2 teaspoon pepper, and oregano in a large bowl; form 1-inch meatballs.
Bake on a greased baking sheet 18-20 minutes, until cooked through. Remove; reduce oven to 375°F.
Mix ricotta, 1 egg, basil, remaining salt and pepper, and 1 cup mozzarella in a bowl until smooth.
Spread 1 1/2 cups marinara in a deep 9x13 inch baking dish. Layer 5 noodles, half the ricotta mixture, half the meatballs, 1 1/2 cups sauce, and 1 cup mozzarella. Repeat once.
Top with remaining 5 noodles, sauce, mozzarella, and Parmesan.
Cover with foil; bake 45 minutes. Uncover; bake 10 minutes more, until cheese melts and bubbles.
Rest 20 minutes before slicing and serving.
