Thyme & White Cheddar Potato Gratin
  • 2 tablespoons butter, plus some to melt in pan
  • 2 pounds Yukon gold potatoes, peeled and sliced very thinly
  • 1 cup white cheddar cheese
  • 4 tablespoons chopped chives
  • 2 teaspoons chopped fresh thyme
  • Salt and freshly ground black pepper
  • 1 cup milk
  1. Heat oven to 400° with rack in center. Place a baking sheet on rack below to catch any drips from gratin. Brush a 10-by-5 1/2-inch gratin dish with melted butter.
  2. Cover bottom of gratin dish with one-third of potato slices in an even layer. Sprinkle potatoes with one-third each of thyme, cheese, and chives; season with salt and pepper. Dot with butter. Add a second layer, and season. Top with a third layer of neatly arranged potato slices. Pour milk over potatoes. Sprinkle with remaining third thyme, cheese, and chives, and dot with butter. Season to taste with salt and pepper. Cover with aluminum foil.
  3. Bake for 40 minutes. Remove foil, and continue to bake 10 to 20 minutes, until top is golden brown and potatoes are tender when pierced with the tip of a knife. If the top of the gratin is not golden brown but potatoes are tender, heat the broiler. Place gratin under the broiler for just a few seconds to brown nicely. Serve gratin hot, spooned out into individual servings. Potato gratin will hold well in a low oven (about 200°), covered with aluminum foil for up to 1 hour.
