This tender beef brisket cooked in Instant Pot is the easiest and quickest way to cook it. Served with potatoes and Guinness gravy this hassle free meal will impress everyone!
Remove fat from the beef if there is any. (Some briskets are very lean and others are very fatty) Salt and pepper the brisket, then press the SAUTE button on your Instant Pot and brown in 1 tbsp oil on all sides until golden. This will take between 5-7 minutes. Remove to a separate plate. Then add chopped onions and sauté for 5 minutes, add pressed garlic and sauté for half a minute longer. Press CANCEL to stop the cooking process.
To the Instant Pot add Guinness, tomato passata or crushed tomatoes, brown sugar, Dijon mustard, thyme and bay leaf and mix to combine. Put the brisket in the liquid and spoon some liquid over it. Cover with a lid, turn the valve to sealing and cook on high pressure for 60 minutes. When done allow for a natural pressure release. Then remove to a platter to rest.
Press the SAUTE button on Instant Pot and bring the cooking liquid to a boil, then stir in the mixture of melted butter and flour and let it simmer until thickened. It should take around 1 minute. Taste for seasoning and add more salt if necessary.
Slice the brisket against the grain and serve with Guinness gravy.
