In bottom of ungreased 9x13 inch pan, spread 1 1/2 cups of meat sauce. top with 1/2 of noodles, 1/2 of the Ricotta cheese mixture, and 1/2 of cheese. Top with remaining meat sauce. Sprinkle with Parmesan cheese. Cover and refrigerate overnight. Heat oven to 350 degrees F. Uncover baking dish and bake 50-60 minutes or until noodles are tender and casserole is bubbly.

I do about the same thing except I go ahead and mix the cheese in with the ricotta, chives, egg and oregano.I leave the foil on the pan for 50-60 minutes then remove for 15 minutes more to brown. This is the only way to make lasagna. Works with whole wheat noodles too.
