Healthy Slow Cooker Lasagna


  • 1 pound uncooked 93% lean ground beef
  • 1 small uncooked onion, chopped
  • 1 medium clove garlic, minced
  • 38 ounces canned crushed tomatoes
  • 15 ounces canned tomato sauce
  • 1 teaspoon table salt
  • 1 teaspoon dried oregano
  • 1/2 teaspoon dried basil
  • 1/4 teaspoon crushed red pepper flakes, or to taste
  • 1 cup part-skim ricotta cheese
  • 1 1/2 cups shredded part-skim mozzarella cheese, divided
  • 6 items uncooked lasagna noodles
  • 1/2 cup shredded Parmigiano Reggiano cheese


  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.
  2. Stir in crushed tomatoes, tomato sauce, salt, oregano, basil, and red pepper flakes; simmer 5 minutes to allow flavors to blend.
  3. Meanwhile, in a medium bowl, stir together ricotta cheese and 1 cup of mozzarella cheese.
  4. 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.
  5. Cover slow cooker and cook on low setting for 4 to 6 hours. Remove cover; turn off heat and season to taste, if desired.
  6. 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.
