Traditional British Shepherd's Pie Recipe

The first thing I notice when this Shepherd’s Pie goes into the oven is the aroma of lamb, onions, and Worcestershire sauce settling into the kitchen. It is a particularly satisfying version because the filling uses a full 2 pounds of ground lamb, so every spoonful has a generous, savory bite rather than being mostly gravy and vegetables. Three onions cook down with the lamb, while carrots and peas bring sweetness and color. It is a traditional British combination, but the Worcestershire sauce gives the sauce a deeper, slightly tangy edge that keeps the richness of the lamb from becoming heavy. The topping is made with four medium potatoes and 2 tablespoons of butter, and the texture matters here. Mash the potatoes while they are still hot, but do not beat them until they turn gluey; a few soft, rustic ridges make a much better crust. Spread the mash all the way to the edges of the baking dish so the filling is sealed underneath. Those edges brown first, while the center stays tender and creamy. I like to drag a fork lightly across the top before baking, since the little ridges catch the heat and turn crisp. The main practical challenge is getting the filling thick enough before it meets the potatoes. After browning the lamb and softening the onions and carrots, add the beef stock and Worcestershire sauce and let the mixture simmer until it looks rich rather than soupy. If the filling is too loose, it will bubble up around the topping and leave the pie watery. Frozen peas should go in toward the end so they stay bright and do not become mushy. Also let the cooked pie rest for 5 to 10 minutes before serving; this gives the gravy time to settle and makes neat portions much easier to lift. With 25 minutes of preparation and about 40 minutes of cooking, this is well suited to a Sunday supper, a chilly evening, or a make-ahead family meal. Serve it straight from the baking dish with steamed green beans, buttered cabbage, or a sharp dressed salad to balance the lamb and buttery potatoes. A spoonful of mint sauce or a little English mustard at the table is welcome, though the Worcestershire-seasoned filling is flavorful enough to stand on its own. It serves six generously, especially with a simple vegetable alongside.
