Super simple and super yummy!!! It does take a long time to cook, though, so plan ahead if you make this.
1C white rice
1 stick butter (you could use margarine, but not the tub kind, the stick kind)
1 can beef broth
1 can french onion soup
preheat oven to 300. pour rice, soup, and broth into ovenproof bowl, then cut butter into large chunks on top. cook uncovered for at least an hour.
Tonight, it cooked for over an hour, and was still liquidy and crunchy. I popped it in Leslie's oven at 375 for 10-15 more minutes and it was perfect. I think my oven doesn't work quite right, but you could try cooking it at a higher temperature, or just for longer.
