Onion brisket Brisket is one tough piece of meat. This takes only a few minutes to put together, but does need oven time. 1 beef brisket, about 3 lbs. 2 medium onions, sliced thin Preheat oven to 300 degrees. Arrange heavy-duty foil in bottom of roasting pan to enclose brisket completely.
Scatter onion slices on foil.
Put brisket on top. Sprinkle with soup mix and seal tightly. Roast until meat is fork tender, about three to four hours. Serves about four to six. This is for those of you who saw me make this on Channel 9's Saturday show and requested the recipe.
