Trim and season your brisket the way you like it. Take a roasting pan, slice couple of onions into rings and line bottom. Put brisket on top fat side up. Take 2 cups of your favorite bbq sauce and pour on top IF you like sauce. Allows all the juices and fat to run underneath and season the brisket Cook at 250 till fork tender. Helluva lot better smoked with mesquite but works great as an alternative.
