Ingredients

Instructions

  1. 1
    In a large skillet over medium heat, brown ground beef (or sausage) until no longer pink. Add diced onion and garlic; sauté for 2-3 minutes. Drain excess fat and season with salt and pepper.
  2. 2
    In a medium bowl, mix ricotta cheese, egg, 1/4 cup Parmesan, and chopped parsley until well combined.
  3. 3
    Spray the inside of your slow cooker with nonstick spray. Spread a thin layer of marinara sauce on the bottom.
  4. 4
    Place 3-4 no-boil lasagna noodles on top of the sauce (break to fit as needed). Add 1/3 of the ricotta mixture, 1/3 of the meat, a sprinkle of mozzarella, and more marinara sauce. Repeat layers twice more, finishing with a thick layer of sauce and the remaining mozzarella and Parmesan on top.
  5. 5
    Cover and cook on LOW for 4-5 hours, until noodles are tender and cheese is melted. Let lasagna rest for 20-30 minutes before slicing and serving. Garnish with extra parsley.
