Do u put the roast beef in the crock pot raw?

Yes, you can put the roast beef in the crock pot raw. You can also sear it on all sides on high heat just before you put it in. I recommend adding a packet of Lipton's beefy onion soup with 1 - 2 cups of water, just enough water where the top is slightly exposed and also add about 2 tablespoons of Worcestershire sauce. You can cook it for 6-8 hours. Depending on the settings of your crock pot.
