what temperature to slow roast a rump roast
Oven Cooking. To slow-cook a rump roast in the oven, set the oven to 250 F. At this temperature, the roast will cook in about four hours, depending on the size of your roast. Place the roast in an oven-proof pot or Dutch oven with a lid. Add 1/2 to one cup of broth or red wine, so that the roast is partially covered.
