Classic Shepherd's Pie

Shepherd's pie is a great way to use leftover potatoes from a Christmas feast, and that's exactly what I did! I used Alton Brown's Shepherd's Pie recipe for inspiration, using lean ground beef instead of lamb, leaving out the tomato paste and adding a 10 oz package of chopped mushrooms and extra corn. I also used Yukon golds to make the mashed potatoes. I used about 4-5 cups of mashed potatoes for the top. I also broiled the pie for about 3-5 minutes at the end to get it nice and brown.
