Beef Wellington is a luxurious British dish that consists of a tender beef fillet coated with pâté and wrapped in puff pastry. The beef is seared to seal in the juices and then spread with a layer of pâté, such as foie gras or mushroom duxelles. It is then wrapped in puff pastry and baked until the pastry is golden and crispy. Beef Wellington is often served with a rich red wine sauce and is a popular choice for special occasions or dinner parties.
