Slow-Cooker Lasagna

Step 1
Mix ricotta cheese, 1 1/2 cups mozzarella cheese, 2 tablespoons Parmesan cheese, egg, and parsley in a medium bowl; set aside.

Step 2
Brown meat in large skillet; drain. Stir in spaghetti sauce and water.

Step 3
Spoon 1 cup meat sauce into a slow cooker; top with layers of half each of the noodles (broken to fit) and cheese mixture. Cover with 2 cups meat sauce. Top with remaining noodles (broken to fit), cheese mixture, and meat sauce. Cover with lid.

Step 4
Cook on LOW until liquid is absorbed, 4 to 6 hours. Sprinkle with remaining mozzarella and Parmesan; let stand, covered, until melted, about 10 minutes.
