1 pound (16 ounces) ground beef
1/2 cup diced white onion
1 teaspoon minced garlic
1 (24 ounce) jar spaghetti sauce
1/2 cup water
1 (15 ounce) container ricotta cheese
2 cups mozzarella cheese
1/4 cup grated Parmesan cheese
1 whole egg
2 Tablespoons fresh parsley or 2 teaspoons dried parsley
6 uncooked lasagna noodles
1 In a large skillet brown beef and onion. Add garlic and cook for one minute. Drain.
2 Add spaghetti sauce and water and simmer for about 5 minutes.
3 Mix ricotta, 1 1/2 cups mozzarella, 2 Tablespoons Parmesan, egg and parsley.
4 Pour 1 cup of spaghetti meat sauce into a 4 to 6 quart sized slow cooker. Place half of the noodles and half of the ricotta mixture on top of the sauce. Cover with 2 cups meat sauce. Top with remaining noodles (If the noodles don't fit exactly break them to fit) and cheese mixture and meat sauce.
5 Cook on low for 4 to 5 hours or until noodles are soft. Sprinkle with 1/2 cup of mozzarella and remaining parmesan. Cover with the lid to melt the cheese and let it sit for 10 minutes before serving.
6 Do not overcook and don't try to speed up the process by cooking it on high.
7 Works best with a 4 to 6 quart size slow cooker.
