How long....?!
Answers: do I cook 3 country style ribs for at 350?
Depends on the size of the ribs, but I would say about 45 min. then check them and see if they are done.

One hour, covered
until you get an internal temp of 160 deg. F. or 45 min in a preheated oven
45 minutes to 1 hour in a 350 oven.
