  • 1 lb Ground beef or Italian beef sausage
  • 1 medium Onion, finely chopped
  • 2 cloves Garlic, minced

  • 24 oz Marinara sauce, jarred or homemade
  • 15 oz Ricotta cheese, whole-milk Use part-skim for a lighter version
  • 8 oz Mozzarella cheese, shredded
  • 1/2 cup Parmesan cheese, grated

Noodles and Seasoning

  • 12 oz Lasagna noodles, regular Broken to fit the cooker
  • 1 tbsp Italian seasoning
  • to taste Salt and black pepper

Instructions
 

Preparation

  • Heat a skillet over medium-high. Add ground beef or beef sausage, chopped onion, and garlic. Cook until the meat is browned and the onion is soft. Drain excess fat.
  • Spoon a thin layer of marinara over the bottom of the slow cooker to prevent sticking.

Layering

  • Break noodles to fit and lay a single layer over the sauce. Dollop spoonfuls of ricotta across the noodles. Sprinkle mozzarella and some meat. Add another thin layer of sauce.
  • Continue layering noodles, ricotta, mozzarella, meat, and sauce until ingredients are used. Finish with a generous layer of mozzarella and a sprinkle of Parmesan.
  • Sprinkle Italian seasoning, salt, and pepper evenly over the top.

Cooking

  • Cover and set the slow cooker on low. Cook for about 4-6 hours, until the noodles are tender and cheese is melty.
  • Turn off the cooker and let the lasagna rest for 5-10 minutes before cutting to help it set for cleaner slices.

Notes

Store leftovers in an airtight container for up to 3-4 days in the refrigerator, freeze for up to 3 months. Reheat in microwave or a preheated oven.
