Ingredients

  • 4 tablespoons unsalted butter, plus more for greasing
  • 2 tablespoons extra-virgin olive oil
  • 2 1/2 pounds trimmed spinach (not baby spinach)
  • 4 shallots, finely chopped (1 cup)
  • 1 cup dry white wine
  • 2 cups heavy cream
  • Salted Herbs
  • Freshly ground pepper

Method

  • Preheat the oven to 425 degrees .
  • In a large saucepan, melt 2 tablespoons of the butter in 1 tablespoon of the olive oil.
  • Add the spinach in large handfuls, letting each batch wilt slightly before adding more.
  • Cook the spinach over high heat, stirring occasionally, until wilted, about 7 minutes.
  • Transfer the spinach to a strainer set over a large bowl to drain.
  • Let the cooked spinach cool slightly, then squeeze out all of the excess water from the leaves.
  • Wipe out the saucepan, then use it to melt the remaining 2 tablespoons of butter in the remaining 1 tablespoon of olive oil.
  • Add the shallots and cook over moderately high heat, stirring, until softened, about 3 minutes.
  • Add the white wine and cook, stirring, until absorbed, about 3 minutes.
  • Add the heavy cream and bring just to a boil.
  • Simmer over moderate heat, stirring occasionally, until reduced by half, about 7 minutes.
  • Stir in the Salted Herbs and season lightly with pepper.
  • Fold the spinach into the cream sauce and scrape the mixture into a buttered 1 1/2-quart baking dish.
  • Bake the creamed spinach for about 15 minutes, until bubbling and the sauce is thickened.
  • Let stand for 5 minutes before serving.
