A rich and comforting slow cooker lasagna made with tender no-boil noodles, a savory meat sauce, and layers of creamy, cheesy goodness—all with minimal hands-on effort.

Ingredients

  • 1 lb ground beef or Italian sausage
  • 1 medium onion, diced
  • 3 cloves garlic, minced
  • 3 cups marinara sauce
  • 2 tbsp tomato paste
  • 2 tsp Italian seasoning
  • 1 tsp salt
  • 0.5 tsp black pepper
  • 9 lasagna noodles, uncooked
  • 15 oz ricotta cheese
  • 1 large egg
  • 2 cups shredded mozzarella cheese
  • 0.5 cup grated Parmesan cheese
  • 1 tbsp olive oil

Instructions

  1. Heat olive oil in a skillet over medium heat. Cook the ground meat with the onion until browned. Add the garlic and cook until fragrant.
  2. Stir in marinara sauce, tomato paste, Italian seasoning, salt, and black pepper. Simmer for 5 minutes.
  3. In a bowl, mix ricotta cheese, egg, and half of the Parmesan cheese.
  4. Lightly grease the slow cooker. Spread a thin layer of meat sauce on the bottom.
  5. Add a layer of uncooked lasagna noodles, breaking them to fit if needed.
  6. Top with more sauce, dollops of the ricotta mixture, and a sprinkle of mozzarella.
  7. Repeat layers until ingredients are used, finishing with sauce, mozzarella, and remaining Parmesan.
  8. Cover and cook on low for 4–5 hours, until noodles are tender.
  9. Let rest for 15 minutes before slicing and serving.

Notes

  • No need to boil noodles before layering.
  • Letting the lasagna rest helps it set properly.
  • Use a 6-quart slow cooker for best results.
  • Customize with vegetables or different meats.
