Equipment

Ingredients

  • non-stick cooking spray
  • 16 oz. lasagna noodles (uncooked) I use Barilla brand - Regular lasagna noodles, not no boil noodles.

Meat Mixture

  • 1 lb. lean ground beef
  • 1 white onion diced
  • 1 tsp. salt
  • ½ tsp. ground pepper
  • 2 tsp. Italian seasoning
  • ½ tsp. garlic powder
  • 48 oz. Rao's Marinara Sauce (two 24-oz. jars)
  • 1 cup water

Cheese Mixture

  • 2 large eggs
  • 2 cups shredded mozzarella
  • 15 oz. whole milk ricotta
  • 1 cup shredded parmesan
  • ½ tsp. salt
  • 1 tsp. dried parsley or dried oregano or Italian seasoning
  • ½ tsp. garlic powder

Topping

  • 2 cups mozzarella cheese
  • dried parsley for garnish (optional)

Instructions

  • In a large skillet brown the meat with the onion. Season the meat with the salt, pepper, Italian seasoning, and garlic powder. Cook your beef until no longer pink. Draining isn’t necessary unless you’re using high-fat ground beef.
  • Pour the marinara sauce in, along with the water. Stir and set aside.
  • In a medium-sized bowl, whisk the eggs, then mix in the cheeses and seasonings. Add the salt, parsley and garlic powder, stir.
  • Before you start layering. Separate the lasagna noodles into 4 evenish piles. Noodle counts vary by brand, but plan for 4–5 noodles per layer
  • Spray slow cooker with non stick spray. Now it's time to layer:
  • 1.5 cups meat sauce mixture (bottom layer)
    4-5 lasagna noodles, can be broken up and can be stacked (1/4 of the box)
    1.5 cups meat sauce
    1/3 of the cheese mixture (dollop it on, then spread it out)
    4-5 lasagna noodles (1/4 of the box)
    1.5 cups meat sauce
    1/3 of the cheese mixture
    4-5 lasagna noodles (1/4 of the box)
    1.5 cups meat sauce
    1/3 cup cheese mixture
    4-5 Lasagna noodles (1/4 of the box)
    Remaining meat sauce - This will be a little over 2 cups; use it all.
    2 cups mozzarella - Sprinkle evenly on top.
  • Cook on LOW for 4 hours without opening the lid during the cooking time.
  • Serve and enjoy! Sprinkle with parsley if desired for garnish.

Notes

  • If your layers get out of order, don't fret. It will still turn out great!
  • Rao's sauce can be spendy. I find it drastically cheaper at Walmart compared to other stores and be sure to stock up if you ever see it on sale. The flavor of it can't be beat.
