There may be a few steps to this culinary delight but just think of it as a potato adventure! First, you will first need to bake russet potatoes off, using a knife cut off the top and scoop out the filling. Make sure to use Idaho or Russet Potatoes in order to achieve a nice fluffy mash. Next, cream and butter them up to make mashed potatoes. Meanwhile, make your beef filling in a large skillet. Adding flour will thicken up the mixture to make a wonderful gravy. Finish off the filling with traditional Shepherd's Pie veggies of peas and carrots. Now it's time to build your creation. Add the meat filling right into the hollowed out potato skins and top with the mashed potatoes. You can use a piping bag with a tip for a fancy presentation or if you don't have one you can just spoon it right on with a spoon. Finally, bake off and serve! Enjoy!
