Prepare pasta according to package instructions; you may cook for an extra two minutes to make the noodles extra soft. Strain in colander and do not rinse!
Place the noodles in a 9 x 13-inch pan and add 5 slices of American cheese, 1 cup of milk, ½ of the marinara sauce and ½ of the shredded cheese. Mix well in the pan.
Spread the remaining marinara sauce and cheese on top. Cover and bake for 50 minutes. Uncover and bake for 5 minutes. Enjoy!
