Slow Cooker Beef Lasagna

1 lb. lean ground beef
1 small onion, chopped
1  garlic clove, minced
28 oz can crushed tomatoes
15 oz can tomato sauce
1 tsp salt
1 tsp dried oregano
1/2 tsp dried basil
1/4 tsp crushed red pepper flakes
1 cup part-skim ricotta cheese
1 1/2 cups shredded part-skim mozzarella cheese, divided
6 no-cook dry lasagna noodles
1/2 cup shredded Parmesan cheese

Instructions

Heat a large nonstick skillet  and add beef, onion and garlic; cook, stirring frequently, about 5 minutes. Stir in crushed tomatoes, tomato sauce, salt, oregano, basil and red pepper flakes; simmer 5 minutes to allow flavors to blend.

Meanwhile, in a medium bowl, stir together ricotta cheese and 1 cup of mozzarella cheese.

Spoon 1/3 of beef mixture into a slow cooker. Break 3 lasagna sheets in half and arrange over beef mixture; top with half of ricotta mixture. Repeat with another layer and finish with remaining 1/3 of beef mixture.

Cover slow cooker and cook on low setting for 4 to 6 hours. Remove cover; turn off heat and season to taste, if desired.

In a small bowl, combine remaining 1/2 cup of mozzarella cheese and Parmesan cheese; sprinkle over beef mixture. Cover and set aside until cheese melts and lasagna firms up, about 10 minutes.
