Ingredients

Scale
  • 1 pound ground beef or Italian sausage
  • 1 (24 ounce) jar marinara sauce
  • 1 (15 ounce) container ricotta cheese
  • 1 large egg
  • 1/4 cup grated Parmesan cheese
  • 1 teaspoon dried Italian seasoning
  • 1/2 teaspoon salt
  • 1/4 teaspoon black pepper
  • 12 no-boil lasagna noodles
  • 3 cups shredded mozzarella cheese
  • 1/2 cup water

Instructions

  1. In a skillet, brown the ground beef or sausage. Drain off any excess fat. Stir in the marinara sauce and simmer for 5 minutes. Set aside.
  2. In a medium bowl, combine the ricotta cheese, egg, Parmesan cheese, Italian seasoning, salt, and pepper. Mix until smooth.
  3. Lightly grease the bottom and sides of a 6-quart slow cooker. Pour 1 cup of the meat sauce mixture into the bottom of the slow cooker and spread evenly.
  4. Arrange 4 no-boil lasagna noodles over the sauce, slightly overlapping if necessary.
  5. Spread half of the ricotta cheese mixture over the noodles.
  6. Sprinkle 1 cup of the mozzarella cheese over the ricotta layer.
  7. Spoon half of the remaining meat sauce over the mozzarella. Add 1/4 cup of water around the edges of the slow cooker.
  8. Repeat the layering process: 4 noodles, the remaining ricotta mixture, 1 cup of mozzarella, and the remaining meat sauce.
  9. Top with the final 4 noodles and the remaining 1 cup of mozzarella cheese. Pour the remaining 1/4 cup of water over the top layer.
  10. Cover the slow cooker. Cook on LOW for 3 to 4 hours or on HIGH for 1.5 to 2 hours, until the noodles are tender and the cheese is melted and bubbly.
  11. Let the crockpot lasagna rest for 10 minutes before slicing and serving.

Notes

  • For a richer flavor, substitute half of the ground beef with Italian sausage.
  • If you prefer a less sweet sauce, use a high-quality crushed tomato base instead of jarred marinara.
  • This recipe works well for meal prep; you can assemble the layers the day before and refrigerate before cooking.
