Scalloped Potatoes

Ingredients

  • 2 Tbsp butter
  • 1 small onion
  • 2 garlic cloves, minced or pressed through a garlic press (about 2 tsp)
  • 4 lbs russet potatoes (about 8 medium), peeled and cut into 1/8 in slices
  • 3 c heavy cream
  • 1 c whole milk
  • 4 sprigs fresh thyme
  • 2 bay leaves
  • 2 tsp table salt
  • 1/2 tsp ground black pepper
  • 4 oz cheddar cheese, shredded (about 1 c.)

Instructions

  1. Adjust an oven rack to the middle position and heat the oven to 350 degrees. Melt the butter in a large Dutch oven over medium-high heat. Add the onion and cook until softened and lightly browned, 5 to 7 minutes. Add the garlic and cook until fragrant, about 30 seconds. Add the potatoes, cream, milk, thyme, bay leaves, salt and pepper, and bring to a simmer. Cover, adjusting the heat as necessary to maintain a light simmer, and cook until the potatoes are almost tender (a paring knife can be slipped into and out of the center of a potato slice with some resistance), about 15 minutes.
  2. Remove and discard the thyme sprigs and bay leaves. Transfer the potato mixture to a 3-qt gratin dish and sprinkle with the cheese. Bake until the cream has thickened and is bubbling around the sides, and the top is golden brown, about 20 minutes. Cool for 5 minutes before serving.
