How to Make It
Preheat oven to 350°F. Stir together sausage, marinara, cottage cheese, ricotta, Parmesan, oregano, basil, black pepper, crushed red pepper, 2 1/4 cups of the mozzarella, and 1 teaspoon of the salt in a medium bowl. Spoon mixture into a 2-cup baking dish. Sprinkle remaining 3/4 cup mozzarella over top, and bake in preheated oven until golden and bubbly, 20 to 25 minutes. Sprinkle with chopped parsley.
While dip is baking, cook lasagna noodles according to package directions. Drain and pat dry with paper towels. Cut noodles into triangles.
Pour oil to a depth of 3 inches into a Dutch oven; heat over high to reach 360°F. Fry noodles in hot oil until golden brown and crispy, 2 to 3 minutes. Drain on paper towels, and sprinkle with remaining 1/2 teaspoon salt. Serve pasta chips with dip.
