Drain any excess grease.Add the chopped onion and minced garlic to the skillet and cook for 3–4 minutes until softened.Stir in the marinara sauce, tomato paste, Italian seasoning, sugar, salt, and black pepper. Simmer for 15–20 minutes.In a large bowl, combine the softened cream cheese, ricotta cheese, cottage cheese, Parmesan cheese, and egg. Mix until smooth and creamy.Spread a thin layer of meat sauce over the bottom of the prepared baking dish.Arrange a layer of cooked lasagna noodles over the sauce.Spread one-third of the cheese mixture over the noodles.Spoon one-third of the meat sauce over the cheese layer.Sprinkle with mozzarella cheese.Repeat the layers until all the ingredients are used, finishing with the remaining meat sauce and mozzarella cheese on top.Cover the dish with aluminum foil and bake for 45 minutes.Remove the foil and continue baking for 15 minutes, or until the cheese is melted, bubbly, and lightly golden.Let the lasagna rest for 15–20 minutes before slicing and serving.Garnish with fresh parsley and enjoy.Recipe NotesAllow the lasagna to rest before slicing to help the layers hold together.Freshly shredded mozzarella melts more smoothly than pre-shredded cheese.Simmering the meat sauce longer creates deeper flavor.Assemble the lasagna a day ahead and refrigerate until ready to bake.This recipe freezes well before or after baking.StorageRefrigerator: Store leftovers in an airtight container for up to 4 days.Freezer: Freeze tightly wrapped for up to 3 months.Reheating: Warm in a 350°F oven until heated through or microwave individual portions until hot.
