Ingredients

  • 1 lb ground beef
  • 1 onion, diced

  • 4 cups marinara sauce
  • 15 oz ricotta cheese
  • 1 egg
  • 1/4 cup grated Parmesan cheese, plus more for topping

Instructions

  1. 1Brown the ground beef with the onion and garlic in a skillet over medium heat, then drain excess fat and stir in the marinara sauce.
  2. 2In a separate bowl, mix the ricotta cheese, egg, and Parmesan cheese with a pinch of salt and pepper.
  3. 3Spread a thin layer of the meat sauce in the bottom of the slow cooker, then break a layer of uncooked noodles over it, breaking them to fit as needed.
  4. 4Spread a layer of the ricotta mixture over the noodles, followed by a layer of mozzarella, then repeat the layers, ending with meat sauce and a final layer of mozzarella on top.
  5. 5Cover and cook on low for 4 hours or on high for 2.5 hours, until the noodles are tender when pierced with a fork.
