Penne Pasta Bake

This dish is crazy easy and devoured by all.

1 box of penne
1 jar of marinara sauce
1 jar of a quality Alfredo  sauce - I have found that all Alfredo sauce is not created equal. Skip the value brands and go for a good quality sauce. I like new the Newmans brand.
2 cups of mozzarella cheese-divided
Parmesan to top

Cook the pasta as directed on the box. In a large bowl mix marinara and alfredo, add the hot pasta and combine. Add 1.5 cups of cheese and stir it until the cheese is evenly distributed. Pour into a 9X13 baking dish and top with the remaining cheese and grated Parmesan. Bake at 350 until the cheese is melted and bubbly, maybe 20-30 minutes but I really don't know the exact. I just watch it.
