Question: how long do you keep a roast in a crock pot?
Answer: Cook for 8-10 hours. If you are a bit short on time, you can turn the slow cooker on to "high" for one hour to get things boiling, then turn back down to low. I do NOT recommend cooking this on high for 4-5 hours. You can if you want, it will be cooked, but it will not be as tender!
