2 pounds beef brisket
1 teaspoons salt
1/2 teaspoon pepper
2 cups sliced onions
For the Sauce
1/2 cup white wine
2 tablespoons tomato paste
2 tablespoons Worcestershire sauce
1-2 teaspoon liquid smoke
1 can 5 oz. tomato sauce
1 tablespoon corn starch mixed with 2 tablespoons water
Cut the brisket into 4 pieces.
Put salt and pepper on the brisket pieces and let it sit while you get your other ingredients together.
In a small cup or bowl, mix together all the ingredients for the sauce.
Place sliced onions in the inner liner of your pressure cooker or Instant Pot.
Place the sliced beef on top.
Pour over the mixed sauce.
Cook the meat at high pressure for 60 minutes for a brisket with some chew, and at 70-75 minutes for fork tender brisket.
Open the pot and remove the brisket with tongs.
Turn your Instant Pot to sauté and add the corn starch and slurry allow the sauce to thicken.
Cut into 1/4 inch slices and pour sauce over the slices.
