There's no need to cook the noodles first or stay home while this Italian classic slow cooks. Just let it sit a few minutes before serving so it can firm up a bit.
Ingredients

uncooked 93% lean ground beef

1 pound(s)

1 small, chopped

garlic clove(s)

1 medium clove(s), minced

Instructions

  1. Heat a large nonstick skillet over medium-high heat. Add beef, onion and garlic; cook, stirring frequently, breaking up meat with a wooden spoon as it cooks, about 5 to 7 minutes. Stir in crushed tomatoes, tomato sauce, salt, oregano, basil and red pepper flakes; simmer 5 minutes to allow flavors to blend.
  2. Meanwhile, in a medium bowl, stir together ricotta cheese and 1 cup of mozzarella cheese.
  3. Spoon 1/3 of beef mixture into a 5-quart 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.
  4. Cover slow cooker and cook on low setting for 4 to 6 hours. Remove cover; turn off heat and season to taste, if desired.
  5. 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.
  6. Serving size: 1/6 of lasagna
