Instructions

1. 1
   Add the ground Italian sausage to a large sauté pan and cook over medium-high heat until sausage is browned. Remove from heat and drain off any excess grease. Set aside.
2. 2
   Meanwhile, as the meat is cooking, begin to assemble the lasagna. Spray the insert of a large 6-quart slow cooker with cooking spray. Layer ¼ of the pasta sauce, four lasagna noodles (breaking them into smaller pieces as needed to fit evenly to cover the bottom of the slow cooker), ⅓ of the ricotta cheese, ¼ of the mozzarella, ¼ of the parmesan, ⅓ of the cooked ground meat and ⅓ of the chopped spinach. Repeat this process two more times. Then repeat with one more layer of noodles, sauce, mozzarella and parmesan.
3. 3
   Place the lid on the slow cooker and cook on high for 3-4 hours or on low for 6-8 hours, or until the noodles are tender.
4. 4
   Turn off the heat, and sprinkle the top of the lasagna evenly with additional parmesan and fresh basil. Serve immediately.
