🇬🇧 Shepherd’s Pie

Shepherd’s pie is spiced lamb mince with vegetables, topped with creamy mashed potato and baked until golden. The fork marks on the mash create peaks that crisp up in the oven. It is simple, hearty, and satisfying.

History

Shepherd’s pie as we know it — lamb mince under mashed potato — is a 19th-century British invention. The dish evolved from cottage pie, which was made with beef, and the distinction between the two (shepherd’s pie for lamb, cottage pie for beef) became standard in the 20th century. The dish was popular in working-class households because it stretched a small amount of meat with vegetables and potatoes, and it was a way to use up leftovers. During both World Wars, the dish was promoted as a way to make meat rations go further. Today it is a beloved British comfort food, and the version made with slow-cooked lamb shoulder rather than mince is considered by many to be the finest.

The science

The crispy top of a shepherd’s pie is a deliberate result of how the mashed potato is treated before baking. Forking the surface of the mash creates ridges and peaks that expose more surface area to the oven’s heat, which encourages the Maillard reaction — the browning reaction that gives the top its golden colour and savoury flavour. Adding a little butter or egg yolk to the mash helps it brown more evenly and gives it a richer flavour. The filling underneath should be thick rather than watery — if the sauce is too thin, it will bubble up through the mash and make the top soggy. Simmering the filling until it is almost dry before it goes into the dish is the key to a clean, crisp top.

Substitutions

Lamb is traditional but beef, turkey, or a plant-based mince all work — just note that if you use beef, the dish is technically a cottage pie. For a vegetarian version, use a mix of lentils, mushrooms, and finely chopped vegetables, with a strong vegetable stock and a splash of Worcestershire sauce (or a vegan equivalent). For a dairy-free version, use olive oil and a plant-based milk in the mash. Adding a layer of sweetcorn or peas to the filling is a common variation, and a handful of grated cheese on top of the mash is a popular addition in many British households.

Chef's tip

Forking the mash creates peaks that crisp up beautifully.

Drink pairing

A dark ale or red wine. The richness of the lamb and the crisp potato topping both stand up well to a strong, malty beer or a medium-bodied red like a Côtes du Rhône.
