Beef Wellington is a classic British dish that features 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 encased in a layer of flaky puff pastry and baked until golden and crispy. Beef Wellington is often served with a rich red wine sauce and roasted vegetables. It is an elegant and indulgent dinner option that is perfect for special occasions.
