Easy Lasagna

adapted by http://theresalwaysthyme.blogspot.com

1 box oven ready lasagna noodles
1 32-ounce jar of marinara sauce (or homemade)
1 15-ounce container of ricotta cheese
4 cups shredded mozzarella
1/2 cup grated or shredded Parmesan cheese

Preheat the oven to 375°F.

Pour a cup of sauce in the baking dish and then spread it on bottom of baking pan. Then layer the lasagna sheets on top of the sauce, overlapping them a bit, and spread 1/3 of the ricotta on the noodles, sprinkle a cup of mozzarella and spread another cup of sauce top.
Add another layer of noodles, make sure to overlap, and spread more ricotta, mozzarella and sauce. Repeat the layers and then spread remaining sauce on top of last noodle layer and then sprinkle Parmesan on top of sauce, then the last if the mozzarella!

Cover pan with foil, nonstick foil works well here, and bake for about 45 minutes! Remove foil and bake for another 15 minutes, until browned and bubbly! Let stand 10 minutes before cutting into it.
