Step 1

Spray baking dish with cooking oil. Layer sliced onion on the bottom of the glass baking dish. Add just enough white wine to the bottom of the pan so the onions are slightly submerged. Place the brisket on top of the onions and sprinkle with onion soup mix, onion powder, garlic powder and pepper. Evenly spread A-1, Heinz 57, and Worcestershire sauces on the top of the meat.

Step 2

Cover and tightly seal with aluminum foil and bake at 275 °F for 4 – 5 hours. Test the doneness by using a fork. The fork should go in easily and the meat should start to pull apart as you lift it out of the pan.

Step 3

Let the brisket rest covered for at least ½ hour before carving. Once the brisket is carved, put back in the gravy and spoon gravy between the slices. Serve right out of the baking dish.
