Preheat oven to 350 degrees. Cook beef in large skillet over medium-high heat until meat is brown, stirring to separate meat; drain fat. Add spaghetti sauce. Reduce heat to low. Heat through, stirring occasionally; set aside. Combine cottage cheese and sour cream in medium bowl; blend well.
Spoon 1-1/2 cups of the meat sauce in bottom of 9x13-inch baking pan. Place 1/2 of the uncooked noodles over sauce, then 1/2 of the cottage cheese mixture, 1/3 of the mozzarella cheese, 1/2 of the remaining meat sauce and 1/4 cup of the Parmesan cheese. Repeat layers starting with the noodles. Top with the remaining 1/3 of the mozzarella cheese.
Pour water around the sides of the pan. Cover tightly with foil. Bake in preheated 350-degree oven for 1 hour. Uncover; bake 20 minutes more or until bubbly. Let stand 15 to 20 minutes. Garnish as desired. Makes 8 to 10 servings.
