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, which adds flavor and helps to keep the meat moist. The puff pastry is then wrapped around the beef and baked until golden and crispy. Beef Wellington is often served with a rich red wine sauce and is considered a show-stopping centerpiece for special occasions or dinner parties.
