Which British pie combines diced beef and beef kidney in a rich gravy, usually beneath a pastry crust?

Steak and kidney pie is a British pie combining diced beef and beef kidney in a rich gravy, usually beneath a pastry crust.

The filling is commonly made with pieces of steak, kidney, onion, and gravy. A pastry lid is characteristic, while some versions use pastry to line the dish as well. It is often served with vegetables and additional gravy.

The dish belongs to the long British tradition of savoury meat pies, which provided a practical way to cook and serve substantial fillings. Steak and kidney pudding is a related dish, but it uses steamed suet pastry rather than the baked pastry associated with the pie.

The kidney is the feature that distinguishes this pie from an ordinary steak pie. Recipes vary in seasoning and pastry style, but the pairing of beef steak and kidney gives the dish its canonical name.
