Step-by-step instructions

1. 1

   To make the filling, cut the lamb into 1/2-inch pieces. Stem and cut the mushrooms into 3/4-inch pieces.

2. 2

   In a large bowl, mix together the flour, salt, pepper, and allspice. Add the lamb and toss to coat evenly.

3. 3

   In a large nonstick fry pan over medium-high heat, warm 2 Tb of the olive oil. Add the lamb and saute until well browned, about 10 minutes. Transfer to a bowl.

4. 4

   Add the remaining 1 Tb oil to the pan. Add the shallots and garlic and stir for 1 minute.

5. 5

   Add the mushrooms and the bay leaf and saute until well browned, about 6 minutes.

6. 6

   Return the lamb to the pan, stir in the stock and tomato paste and bring to a boil. Reduce the heat to medium-low, cover and simmer until the lamb is tender, about 45 minutes.

7. 7

   Uncover and simmer until the juices thicken, about 2 minutes. Transfer the filling to a 9-inch pie dish.

8. 8

   Preheat the oven to 350°F.

9. 9

   To make the topping, pour water to a depth of 1 inch into a large pot and bring to a boil over high heat.

10. 10

    Peel and slice the potatoes into rounds 1/4 inch thick. Put the potatoes into a steamer basket and set the basket over boiling water. (The water should not touch the bottom of the steamer basket).

11. 11

    Cover and steam until the potatoes are tender when pierced with a small knife, about 12 minutes. Transfer the potatoes to a large bowl.

12. 12

    Add the milk, butter, salt, and pepper. Mash well with a potato masher. Stir in half of the chives. Spoon the potatoes on top of the lamb mixture to cover it completely.

13. 13

    Bake until the pie is heated through and the potatoes begin to brown, about 35 minutes.

14. 14

    Sprinkle with remaining chives and serve immediately.
