This is home cooking at its best, and a great way of using up leftovers from your Sunday roast. If you have any leftover vegies or gravy, then throw them in as well. If you don’t have any leftovers – and to be honest, in my house we usually eat up every morsel – then shepherd’s pie can easily be made from scratch using raw minced lamb.
The most important thing, in my opinion, is to use a shallow baking dish with a large surface area, so you get lots of crunchy potato topping. Serve with buttered minted peas and tomato sauce.
