Beef Wellington

Beef Wellington is a steak dish of English origin, made out of fillet steak coated with pâté and duxelles, wrapped in puff pastry, then baked. Some recipes include wrapping the coated meat in prosciutto, or dry-cured ham to retain its moisture and prevent it from becoming soggy. A whole tenderloin may be wrapped and baked, and then sliced for serving, or the tenderloin may be sliced into individual portions before wrapping and baking.
