Grease/spray a small casserole dish with non-stick spray
In a bowl, combine boiled gnocchi, sauce, ¼ C parmesan, salt and pepper, and Italian seasoning. Mix well.
Transfer contents from the bowl to the casserole dish.
Sprinkle remaining parmesan cheese and mozzarella cheese on the top. You can also sprinkle a pinch of Italian seasoning on top of the cheese if you wish.
Bake for approximately 20 – 25 minutes or until the cheese is melted
