This being St. Patty's week I had already been making and planning Irish-themed meals. I couldn't remember if Alton Brown had done a recipe for this dish or not. A quick trip to the Food Network site proved he did, in fact, have a recipe for Shepherd's Pie.
Now, the reality is, since I used beef and not lamb, this would technically be a cottage pie and not a Shepherds Pie. But, no matter what you want to call it, I call it Good Eats.
I will try this with lamb. And I will update.
