1 lb sweet Italian sausage
3/4-1 lb lean ground beef
1/2 c minced onion
2 cloves garlic, crushed
1 (28 ounce) can crushed tomatoes
2 (6.5 ounce) cans canned tomato sauce
2 (6 ounce) cans tomato paste
1/2 c water
2 T white sugar
4 T chopped fresh parsley, divided
1 1/2 t dried basil leaves
1 1/2 t salt, divided, or to taste
1 t Italian seasoning
1/4 t ground black pepper
12 lasagna noodles - can use oven ready
16 ounces ricotta cheese
1 large egg
3/4 lb mozzarella cheese, sliced
3/4 c grated Parmesan cheese
Cook sausage, ground beef, onion, and garlic in a Dutch oven over medium heat until well browned.
Stir in crushed tomatoes, tomato sauce, tomato paste, and water. Season with sugar, 2 tablespoons parsley, basil, 1 teaspoon salt, Italian seasoning, fennel seeds, and pepper. Simmer, covered, for about 1 ½ hours, stirring occasionally.
Cook lasagna noodles if not using oven ready.
In a mixing bowl, combine ricotta cheese with egg, remaining 2 tablespoons parsley, and 1/2 teaspoon salt.
Preheat oven to 375.
To assemble, spread 1 ½ cups of meat sauce in the bottom of a 9x13-inch baking dish. Arrange 6 noodles lengthwise over meat sauce, overlapping slightly. Spread with 1/2 of the ricotta cheese mixture. Top with 1/3 of the mozzarella cheese slices. Spoon 1 ½ cups meat sauce over mozzarella, and sprinkle with 1/4 cup Parmesan cheese.
Repeat layers, and top with remaining mozzarella and Parmesan cheese. Cover with foil: to prevent sticking, either spray foil with cooking spray or make sure the foil does not touch the cheese. Bake in the preheated oven for 25 minutes. Remove the foil and bake for an additional 25 minutes. Let sit for about 15 minutes before serving.
