Turnip and sweet potato gratin.

Serves 8

Ingredients

  • 1 1/2 pounds turnips (about 3 medium), peeled and cut into 1/4-inch-thick rounds
  • 1 pound sweet potatoes (about 2 medium), peeled and cut into 1/4-inch-thick rounds
  • Coarse salt and ground pepper
  • 1/4 cup all-purpose flour
  • 2 tablespoons unsalted butter, cut into pieces
  • 3/4 cup low-sodium chicken or vegetable broth
  • 1/4 cup dry white wine, such as Sauvignon Blanc
  • 1 cup grated Gruyere cheese (4 ounces)

Directions

  1. Preheat oven to 350°F. In an 8-inch square baking dish, arrange a single layer of turnips and sweet potatoes, overlapping slightly. Season with salt and pepper and sprinkle with one-third of the flour. Repeat to make three more layers, sprinkling with salt, pepper, and flour between layers. Dot top layer with butter, then slowly pour broth and wine into dish, keeping layers intact. Cover with foil and bake until vegetables are tender when pierced with a knife, 45 minutes.
  2. Increase oven temperature to 425°F. Remove foil and sprinkle cheese over dish. Bake until cheese is golden and bubbling, 12 to 15 minutes. Let gratin sit 10 minutes before serving.
