I have a recipe for pot roast of beef which has potatoes, carrots & onion in the bottom, a 2 to 3 pound boneless roast on top of that, then 1/2 cup water or brother poured over all. It says to cook on low for 10 to 12 hours or high for 5 to 6 hours.
I would rather cook it on low and I was wondering if I could brown the roast and put the meal on the night before, say around midnight, and cook until around 6:00 p.m. the next day? Or will it be too much? Should I leave the vegetables out?
I can't seem to find any information on overcooking a roast. Thanks for your help.
