French Onion Rice

I made this side dish tonight and got mixed reviews; however, it is one of my favorite side dishes and I thought I'd share it with you.  It is so simple and great for potlucks.

1 cup rice (not instant) (I use brown)
1 can French Onion soup
1 can beef consume
1 stick of butter (I left this out and added 1 cup of water)
1 can drained mushrooms

Mix it all together in a 9x9 dish, bake at 350 for 1 hour (may need a bit more time), stir before serving.
