Bake brisket for approximately 3 1/2 hours. The brisket is done when a fork slides into the meat easily. If the meat is still tough after the initial baking, bake for an additional 30 minutes. Once the brisket is removed from the oven, let rest for approximately 20 minutes before slicing. You can also chill, wrapped well in plastic wrap, until needed.
