One of the great things about having a roast leg of lamb on Christmas Eve is all that leftover meat.
After dinner, I cut all of the meat from the bone and begin to prepare it for the casseroles that will be interspersed between other holiday meals. The bone itself is then boiled with any residual rosemary leaves for the broth. I split the meat into two batches: cubes for curry and some to be minced for Shepherd's Pie. Both the curry and the seasoned minced lamb freeze well, so creating meals a few weeks later is a breeze.
Shepherd's Pie is one of my favorite winter comfort foods. In the states, we often think of the pub versions with loads of cheese.
I'm more of a traditionalist with those sorts of foods, though, so my version has no cheese in it and I instead sprinkle each serving with a small amount of grated cheese just after plating.
To me, there are three secrets to really good Shepherd's Pie.
The first, of course, is the seasoning. It should be quite rich in flavor but still impart a homey and simple taste. Starting out with a well-seasoned leg of lamb and flavorful roasted veggies helps get the whole thing started out right.
The second is to include just enough of the rich sauce to cover the meat and no more. A soupy casserole is no good. The meat layer should be dense and the potato layer should be light and fluffy.
The third is stiff mashed potatoes. So no cream or other liquid added at all to the potato mash, just enough butter to flavor and bind.
Once you know those tricks, making perfect Shepherd's Pie is a piece of cake.
2 tablespoon olive oil
1 lb lean minced lamb
1 large onion, peeled and finely chopped
1 large carrot, peeled and finely chopped
2 cloves garlic, peeled and finely chopped
1 cup chopped mushrooms
1 cup peas (frozen are fine)
2 tablespoon Worcestershire sauce
1 teaspoon tomato purée
1 teaspoon chopped fresh thyme leaves
1 cup red wine
1 cup lamb stock
3-5 potatoes
2 tablespoons butter
Cook onion and carrot in olive oil until soft. Add minced lamb, cook until lamb is browned and pan begins to caramelize. Add mushrooms and garlic and cook for 3-4 more minutes.
Add tomato puree and Worcestershire sauce. I have a particularly heavy hand when it comes to Worcestershire sauce in Shepherd's Pie. It is, in my opinion, a key ingredient and one that shouldn't be skimped.
Add stock, wine, and herbs. Cook until reduced by half. Add peas.
Meanwhile boil potatoes until soft. Drain and return to hot pot, tossing until dry. Add butter, salt and pepper, and mash lightly.
Assemble lamb mixture in casserole. Carefully spoon potatoes on top and spread evenly, sealing edges well. Use a fork to make a criss-cross pattern then brush with melted butter.
Bake in 375' oven for 20 minutes or until slightly browned and edges are beginning to bubble.
Can be made a day ahead and refrigerated. Just bring to room temperature before cooking and add 10 minutes to cooking time.
