I'm out on a limb here but I think rehydrated potato flakes work perfectly with this. Lots of milk and butter and making sure the filling is of excellent quality and no one will know the difference. Saves time and mess.
Miss M., I’ll eat potatoes any way they come ;-)
(My husband does a Shepherd’s Pie that is low-carb, and uses cauliflower cooked in chicken broth and garlic and then mashed, for the topping...I haven’t quite warmed up to it yet ;-)

Even easier - get a package of Bob Evans mashed potatoes (they’re usually in the same refrigerator case as the sausage and kraut). They’re real mashed potatoes that you’re supposed to just heat up. One covers an average casserole dish. I’ve used them on many shepherd’s pies over the years.
