Traditional shepherd's pie is a layered dish consisting of ground lamb or beef, carrots, celery, peas, salt, pepper, beef stock and Worcestershire sauce. It is topped with mashed potato. Bake shepherd's pie in the oven at 400 degrees Fahrenheit for 20 minutes.
The main two components of shepherd's pie are meat and potatoes. Traditional Irish recipes make use of lamb or beef or a combination of both meats. Another important component of the dish is Worcestershire sauce, added for flavor. Combined with beef stock, Worcestershire sauce helps to season the meat and helps to form a moist gravy.
To make a traditional shepherd's pie, heat butter or oil in a large frying pan and add vegetables. Soften the vegetables over medium heat and then add the meat. Drain fat from the cooked meat. Add Worcestershire sauce and beef stock and allow the liquids to reduce slightly. Next, boil potatoes with salt for about 15 minutes, then mash with butter, milk or cream and salt. Spoon the meat into a large baking dish and pour pan juices over the meat, spreading evenly. Finally, spoon mashed potatoes over meat, spreading the potatoes evenly. Place the shepherd's pie into the oven and bake at 400 degrees Fahrenheit for about 20 minutes or until potatoes are browned and slightly crisp.
