  • 1 pound ground beef or Italian sausage
  • 15 oz ricotta
  • 1 egg
  • 1 teaspoon salt
  • 1 teaspoon basil
  • 1/4 teaspoon pepper
  • 1/4 cup grated parmesan plus more for topping
  • 24 oz marinara sauce
  • 10 oz lasagna noodles no boil
  • 8 oz shredded mozzarella cheese


  • Spray entire slow cooker insert with non-stick spray.
  • Add ground beef to a large saute pan, and cook over medium-high heat until browned and cooked through. Add tomato sauce and diced tomatoes. Stir together. This will make your sauce.
  • In large bowl, mix Ricotta with egg, 1/4 cup parmesan cheese, basil, salt, and pepper.
  • Cover bottom of slow cooker with sauce.
  • Layer pasta on top of sauce. Layer about 4 lasagna noodles — breaking them into smaller pieces as needed to fit — evenly over the sauce to cover the bottom of the slow cooker.
  • Take 5 scoops of the ricotta mixture and drop onto noodles and spread evenly over noodles.
  • Top with a layer of mozzarella cheese.
  • Repeat these steps two more times. Sauce, noodles, ricotta, mozzarella.
  • Cook on high for 2 1/2 hours. (see note for boil or traditional noodles)
  • Serve with grated parmesan cheese on top.


If using traditional noodles or “boil” noodles increase cook time to 4 hours and check to see if noodles are soft using toothpick or skewer.
