I use a crockpot for my beef roasts. I take a small beef roast and a small pork roast and put them on about 8:00 am with a chopped up medium onion, seasoned salt and peper and about 3/4 cup of water. Set it on low and let it go for dinner at about 5. You can put carrots and potatos on top about an hour before or cook them seperate. The roasts stay nice and moist and falls apart when it is done. The juice then makes some of the best gravy you will ever eat. It is so simple and best of all it looks like you have slaved all day!!
