In this pot roast with vegetables recipe, easy is the operative word. Use chuck roast for this beef pot roast, but brisket, 7-bone roast, and other tougher cuts also work well. The slow-braising method results in a remarkably tender and flavorful meal with natural pan gravy. Potatoes, carrots, mushrooms, garlic, and sweet onions cook with the roast for a built-in side dish.
