Though these Cottage Pies bear a striking resemblance to traditional Shepherd’s Pies, there’s one key difference. Both boast a crust of mashed potatoes, but a Cottage Pie uses ground beef in the filling, while a Shepherd’s Pie relies on ground lamb. And we took what’s normally at least an hour-long process and cut the cooking time down to 40 minutes, total, by baking our Cottage Pies in individual ramekins as opposed to one large casserole dish. Here, you just need 20 minutes to mash the potatoes, brown the beef, and layer the ingredients in oven-safe dishes. After the pies bake for 20 minutes or less, a warm, comforting dinner is served.
