1. To make béchamel sauce, melt butter over medium heat in 4-quart stock pot. Stir in flour; cook and stir 2 minutes making sure flour doesn’t get brown. Slowly whisk in milk. Continue cooking, stirring constantly, until mixture has thickened and just starts to simmer. Remove from heat; let stand at room temperature.
2. To make pasta sauce, sauté onions, carrots, celery and garlic in olive oil until tender. Add sausage and beef; cook until browned. Add wine and simmer 5 minutes. Stir in remaining ingredients, except noodles and cheese; simmer 30 minutes or until desired thickness, stirring occasionally.
3. Heat oven to 375° F. Spoon about 1 cup tomato sauce into bottom of 13x9x2-inch pan. Top with 4 lasagna noodles. Spread half of the remaining pasta sauce and half the béchamel sauce over noodles. Sprinkle 1 ½ cups mozzarella over the top. Repeat layers with remaining noodles, sauces and mozzarella cheese. Sprinkle Parmesan over top.
4. Cover pan with foil and bake at 375° F. for 45 minutes. Remove cover and bake an additional 15 to 20 minutes until cheese is slightly browned on top.
