1Spray 13x9-inch (3-quart) glass baking dish with cooking spray. In 12-inch skillet, cook beef, onions, salt and pepper over medium-high heat 5 to 7 minutes, stirring occasionally, until beef is brown; drain. Stir in tomato sauce and water. Heat to boiling; reduce heat to medium-low. Simmer uncovered 10 minutes.
2In medium bowl, beat egg with fork. Stir in ricotta cheese, Swiss cheese, parsley and 1/4 cup of the bacon.
3Spread about 1 cup of the beef mixture in baking dish. Top with 4 uncooked noodles. Spread half of the ricotta mixture, 2 cups beef mixture and 3/4 cup of the Cheddar cheese over noodles. Repeat layers once, starting with 4 noodles. Top with remaining noodles, beef mixture, Cheddar cheese and bacon. Spray 15-inch sheet of foil with cooking spray. Cover lasagna with foil, sprayed side down. Refrigerate at least 2 hours but no longer than 24 hours.
4Heat oven to 350°F. Bake covered 45 minutes. Uncover and bake about 30 minutes longer or until bubbly and golden brown. Cover and let stand 10 minutes before cutting.
