What is the Cooking time for Stouffer's frozen lasagna?

"Read the box stupid!! it doesnt take a rocket scientist to read a box! its not even healthy eat some broccolli or something instead"

wow whoever put this is a jerk. how about answering the question instead of being rude?

anyway if you haven't found out already, preheat oven to 400 degrees, take the cover off of the lasagna, bend it a little & put it back on so it covers it a little.

cook for 1 hour 40 minutes if frozen & 55 minutes if thawed.
