In a large skillet over medium heat, cook Italian sausage or ground beef until fully browned and crumbly. Drain excess fat, then add spaghetti sauce, tomato sauce, and Italian seasoning. Simmer gently for 5 to 10 minutes, stirring occasionally, until sauce thickens and aromas develop.

In a large bowl, mix cottage cheese, softened cream cheese, sour cream, beaten egg, and dried parsley. Stir until completely smooth and creamy, ensuring there are no lumps.

Lightly grease a 23x33 cm (9x13 inch) baking dish. Spread 240 ml (1 cup) of meat sauce evenly over the bottom. Layer six cooked noodles lengthwise in the dish, slightly overlapping to avoid gaps. Spread half of the cheese mixture gently over the noodles to avoid disturbing them. Arrange one third of the mozzarella slices in a single layer, spoon half of the remaining meat sauce over, and sprinkle with 15 grams (1/4 cup) grated Parmesan.

Repeat the layering process with the remaining noodles, cheese mixture, one third of mozzarella slices, remaining meat sauce, and another 15 grams (1/4 cup) Parmesan cheese. Finish by layering with the remaining mozzarella and Parmesan for a deeply cheesy top.

Cover the dish tightly with aluminum foil to prevent overbrowning. Bake in a preheated oven at 190°C (375°F) for 25 minutes. Remove foil carefully and bake uncovered for an additional 30 minutes or until cheese is golden and sauce bubbles. Allow to rest at room temperature for 15 minutes before slicing to ensure clean, set layers.
