How to Make Shepherd's Pie

1. Heat butter in large skillet over medium-high heat until foaming. Add onion and carrots and cook until soft, about 8 minutes.

2. Add the lamb or beef and cook, breaking up meat into small pieces with wooden spoon or silicone spatula, until evenly browned, about 10-12 minutes. Add flour and tomato paste and cook until paste begins to thicken, then add Guinness.

3. Add chicken stock, A1 sauce, and rosemary and simmer over medium heat, stirring frequently, until mixture is thick but still saucy, 15 to 20 minutes.

4. If the sauce has a lot of fat floating on the top, skim off with a ladle and discard. Remove from heat, stir in peas, and season with salt and pepper to taste. Transfer to broiler-safe 2-quart casserole dish.

5. Adjust oven rack to upper-middle position and heat oven to 375 degrees F. Bring potatoes, 1/2 teaspoon salt, and water to cover, to a boil in a large saucepan over high heat. Reduce heat to medium-low and simmer until tender, 15 to 20 minutes. Drain potatoes, return to saucepan, and add roasted garlic. Mash potatoes with butter, cream, and chives until smooth. Season with salt and pepper to taste. Top the meat mixture with dollops of the mashed potatoes then spread them out over the top.

6. Brush with egg and drag fork across top to make ridges.

7. Bake the pie until the potatoes have begun to brown and the edges are bubbling, about 15 minutes. Let stand at room temperature for 15 minutes before serving.
