The beef is seared to seal in the juices and then baked until the pastry is golden and crispy. Beef Wellington is often served with a rich mushroom sauce and is a popular choice for special occasions and fine dining. It is a luxurious and elegant dish that requires skill and precision to prepare, making it a highlight in British food restaurants.
