I am currently slow cooking a beef stroganoff for my family for tonight.

My husband just called me a moment ago and told me he has bought us all tickets to go to the movies around 5pm tonight... so I was wondering if it is possible to throw the pasta into the slow cooker with the rest of the ingredients? Will it cook through? How long should I need to cook the pasta for? If it could be done, it would be ideal as then I could just leave dinner, go see the movie, come home and serve it up to my hungry tribe!
TIA,
Lisa
