means A whole beef fillet coated in mushroom duxelles and often a layer of ham or crêpe, wrapped in puff pastry, and baked until the crust is golden and the meat stays pink inside.

from The dish's name almost certainly honors Arthur Wellesley, the Duke of Wellington, though nobody can prove he ever ate it or that it was named in his lifetime — the earliest solid references are 20th-century, long after his famous 19th-century victories. Some food historians suspect the name was simply a patriotic British flourish slapped onto a beef-in-pastry preparation (a technique with older French roots, akin to filet de bœuf en croûte) to make it sound properly English and heroic. The popular tale of a chef inventing it specifically for the Duke, or shaping it to resemble a military boot, is charming but unverified folklore rather than documented history.
