In my house growing up, when your birthday rolled around you got to make a special request for what the family would have for dinner, and every year without fail, i would ask my stepdad to make me twice-baked potatoes. He made them by scooping out the insides of tender baked potatoes and whipping them with butter, sour cream, and green onions before refilling the potato skins, loading the top with cheddar and bacon and popping them back in the oven to get hot and melty. They were entirely indulgent and entirely delicious. Now, to achieve those two qualities you could make them just as he did, or you could take the same ingredients and fashion them into a creamy and comforting casserole that makes it a little easier to feed a crowd. We did just that and its everything you could want a casserole to be.
