Turnip Gratin

  • 2 tablespoons unsalted butter 
  • 1 tablespoon chopped thyme 
  • 1 1/2 teaspoons kosher salt 
  • Rounded 1/8 teaspoon cayenne 
  • 1 cup heavy cream 
  • 1 cup grated Parmigiano-Reggiano 
  • 1 bunch of white turnips

Directions

Preheat oven to 450°F with rack in middle. Melt butter in an ovenproof 12-inch heavy skillet, then cool. Slice turnips paper-thin, then arrange one third of slices, overlapping tightly, in skillet, keeping remaining slices covered with dampened paper towels. Sprinkle with about a third of thyme, kosher salt, and cayenne. Make 2 more layers. 

Cook, covered, over medium heat until underside is browned, about 10 minutes. Add cream and cook, covered, until center is tender, 20 to 25 minutes. Sprinkle evenly with cheese, then bake, uncovered, until golden and bubbling, 10 to 15 minutes. Let stand 5 minutes before serving.
