Golden, crackly-skinned baked potatoes—split wide and steaming—get the full steakhouse treatment in this elevated comfort-food recipe. Instead of the usual chili-and-cheddar situation, these are piled with ground beef simmered until glossy in a red wine–shallot pan sauce, then finished with a cool dollop of truffle-kissed crème fraîche, a shower of crispy shallots, and a few salty curls of shaved cheese.
