Lazy Slow Cooker Lasagna

This slow cooker lasagna is so delicious! You don't even have to cook the noodles before you place them in the crockpot!
Prep Time: 30 mins
Cook Time: 4 hrs
Total Time: 4 hrs 30 mins
Servings: 14 servings

Ingredients
 

"The Sauce"

  • 2 lbs Italian sausage
  • 4 garlic cloves, minced
  • 2-24 oz jars marinara sauce
  • 1 cup water
  • 1 tablespoon Italian seasoning
  • salt and pepper - to taste

Herb Ricotta

  • 15 oz ricotta
  • 1/3 cup fresh parsley - chopped
  • 1 teaspoon Italian seasoning

Cheeses

  • 18 oz mozzarella, shredded
  • 4 oz parmesan, shredded (about 1 1/2 cups)
  • 2 oz romano cheese, shredded
  • 15-18 lasagna noodles, UNCOOKED - if you have a circular crock pot like me, you will probably only use 15 noodles. If yours is oval/rectangular you'll use 18)

Instructions
 

  • In a pot over medium heat, cook the sausage until brown, breaking it into small crumbly pieces as it's cooking. Towards the last minute or two of browning add the minced garlic. Remove from heat. Drain the sausage of any liquid or grease that may have accumulated.
  • Add the 2 jars of marinara and the 1 cup of water to the sausage bowl. Stir in the 1 tablespoon Italian seasoning. Taste, and season with salt and pepper. This will be referred to as "the sauce." Set aside. 
  • In a small bowl combine the ricotta, parsley, and Italian seasoning. Set aside.
  • Coat the inside and the sides of a large crock pot with nonstick cooking spray. Begin layering starting with the sauce. Being sure to add about 2 cups of the sauce to the bottom of the crockpot. Then top the sauce with noodles. Breaking the noodles if they don't fit, so that it covers all of the sauce.
  • Add a thin layer of ricotta atop the lasagna noodles. Generously sprinkle the shredded cheeses overtop the ricotta. Repeat these layers until all ingredients are used and it fills your crock pot. (Sauce, noodles, ricotta, cheeses, sauce noodles, ricotta, cheeses etc.) Ending with the shredded cheeses at the top. 
  • Cook on high for 4 hours. Serve warm with a sprinkling of fresh parsley. 

Notes

**Use a large crockpot. Mine is circular. It's easier to make in an oval/rectangular type crockpot. I've made it in my moms oval crockpot and it works great! Also works well in circular. 
I usually do about 5 lasagna noodle layers.
