If it hasn't finished cooking yet, it's 118 to 20 minutes a pound for medium rare at 350. Rolled roast needs 5 to 10 minutes more per pound. If you're using a thermometer, it should be 140 (rare) to 170 (well done). So says The Joy of Cooking.

Thanks! I haven't started it yet, so I'll follow these suggestions.

Typo alert! 18 to 20 minutes.

Heh, I just browned a 3lb. beef eye round roast, popped it in the slow cooker, covered it with a bunch of cut up potatoes, onions, celery, carrots and mushrooms. Poured two cups of beef broth over the whole thing and turned it on about 10pm. Gonna smell GOOD when we get up in the morning!!
