Layers of tortellini, Italian sausage, and lots of cheese make this unique and delicious Slow Cooker Tortellini Lasagna. Your family will love this fun take on the classic Italian layered pasta dish.
To a large deep skillet over medium heat, add the sausage and onion. Break the sausage up and cook it through. Once cooked, remove any excess grease from the pan. Stir in the two jars of marinara sauce.
Make the cheese mixture by combining the cottage cheese, 1 cup of mozzarella, Parmesan cheese, and garlic in a medium bowl. Stir well.
Spray the inside of a large slow cooker with non-stick spray.
Start layering the ingredients 1/3 at a time, for a total of three layers. Pour 1/3 of the sauce into the bottom of the slow cooker, then add 1/3 of the tortellini, then 1/3 of the cheese mixture, and repeat. Top with the remaining mozzarella cheese.
Cover with a lid and cook on LOW for 6-7 hours or HIGH for 5 hours. Enjoy!
