Hmm. I always thought a pot roast was cooked in a pot and over the stove. Seems like a lot of wasted electricity to cook a roast in the oven. That said, I'm still trying to find a stove top pot roast that doesnt' turn out dry and leathery. I spent quite a few dollars on sirloin roast and cooked it over the the stove as suggested by someone in another forum. The first time, I turned out fine (but with too much water) but I used chuck the other time I didn't use sirloin.
