  • 1 tbsp. olive oil
  • 1 lb. ground beef
  • 1 lb. Italian sausage removed from the casing
  • 1 medium onion finely chopped
  • 2 cloves garlic minced, or 1 tbsp. garlic paste
  • 8 cups tomato marinara sauce
  • salt and pepper to taste
  • 32 oz. ricotta cheese
  • ½ cup parsley chopped, optional
  • 2 lbs. mozzarella cheese low-moisture, shredded
  • 1 cup Parmesan cheese grated
  • 1 lb. lasagna noodles uncooked, oven-ready
  • 4 eggs
  • 1 tbsp. Italian seasoning


  • Over medium heat, cook 1 medium chopped onion in a skillet until lightly browned. Add 2 cloves minced garlic and stir until browned.
    Then, add 1 lb. ground beef and 1 lb. Italian sausage removed from the casing and cook, breaking up the meat with a wooden spoon, until browned.
    Finally, stir in 8 cups tomato sauce and 1 Tbsp. Italian seasoning. Simmer on low for approximately 30 minutes, then season with salt and pepper to taste.
  • In a bowl, combine 32 oz. ricotta cheese with 1 cup Parmesan (reserve some to sprinkle while layering), ½ cup parsley (optional), 4 eggs, and salt and pepper to taste.
    Cover the bottom of your greased slow cooker with 1 cup meat sauce.

  • Top with 3 oven-ready lasagna noodles. Break to fit if necessary and place broken pieces where sauce is uncovered.

  • Ladle more meat sauce over the noodles and spread evenly. Then spoon on ¼ of the ricotta mixture and top with ¼ of the mozzarella cheese plus additional Parmesan.

  • Repeat the layers 3 times. Top the final layer with remaining mozzarella and parmesan. Sprinkle with green onions if desired.
    Cook on low for approximately 7 hours. When complete, set to warming mode and allow the lasagna to rest for 30 minutes before cutting into it. Enjoy!

  • To top with additional meat sauce, double the amount of meat sauce you make.
  • Slice the lasagna into smaller pieces, since it cooks in a deep dish.
  • Let your lasagna rest for 30 minutes on warming mode when it's done cooking before you slice into it so that it keeps its shape.
  • Drain fat from the sausage and ground beef before adding the marinara sauce.
  • Adjust salt and pepper according to how much seasoning is in the marinara sauce.
  • Cook the meat the night before and refrigerate until ready to assemble the dish to save time.
