This has to be the easiest recipe for brisket and it is so good, you can also make this same recipe using a pot roast! If you can make this a day ahead the sauce flavor intensifies the following day, just rewarm over low heat. If you are making a larger brisket then double the ingredients but still only use 2 onions and 1-2 tablespoons fresh garlic. This brisket is melt in your mouth tender!
