Leftover Lamb Pie with a Rosemary Crumb

This is a handy recipe for using up leftover lamb and potatoes from a Sunday roast. I sometimes get bored with my use-it-up standbys of shepherds’ pie, pilaf and curry, so for a change I tried this.

It’s unpretentious, homely cooking but it’s quick, it’s easy and it tastes good. You can make it in individual dishes if you want it to look less rustic. If you have too much crumble, it freezes well and comes in handy whenever you want an instant gratin topping.

Preheat the oven to  200C/400F/Gas Mark 6.

Heat a little oil in a frying pan and cook the onions until golden brown and mix them with the chopped lamb. Moisten with leftover gravy or a little stock and season to taste with salt and freshly ground black pepper.

Whizz the bread with the rosemary in a food processor until you have a green-flecked crumb. Add the grated cheese and pulse briefly to mix.

Layer the lamb and potatoes in an oven proof dish. Cover with the rosemary crumb, dot with butter and bake for 20-30 minutes until piping hot and browned.
