Twice-baked Beef Brisket with Onions
Purchase a whole fresh beef brisket (not corned) or 2 center-cut pieces. Oven-braise the brisket up to 2 days ahead; chill meat and pan juices separately. To serve, slice meat and reheat in sauce. If desired, divide pan juices and meat evenly between 2 casseroles (9 by 13 inch each) in step 3.
