Nani's Creamy Twice Baked Potato Casserole
This comforting casserole takes all the best parts of a loaded baked potato and bakes them together in one bubbly, cheesy dish.
recipesbynani.comThere is something so special about a warm potato dish that brings everyone to the table. This recipe captures all the classic flavors of a twice baked potato but makes it much easier to serve for a big family dinner or a holiday gathering.
My favorite trick for this recipe is to make sure you shred your cheese fresh from a block. It melts so much smoother than the pre shredded bags, and it really makes a big difference in how creamy the final casserole turns out.
