This is my favorite way to cook a roast. You can do it in the crock pot, too, but then you don't braise it first. Your roast should be no less than 2 lbs but no more than 4 lbs. My recipe calls for a large amount of carrots but that's just because I love them when they're cooked with a roast. You don't have to add any veggies if you don't want to. Also, cheaper cuts of meat turn out great this way, don't waste your money on an expensive cut.
