Makes: 8 servings
Prep: 25 mins
Cook: 45 mins
- 2 cups milk
- 3 cloves garlic, smashed and peeled
- 3 pounds baking potatoes, preferably Idaho, peeled and sliced 1/4 inch thick
- 3 ounces Gruyere cheese, coarsely grated (about 3/4 cup)
- Pinch cayenne pepper
- Black pepper
- 1 cup heavy cream
- Place a rack in the top half of the oven and preheat to 375 degrees . In a large saucepan, combine 2 cups water with the milk, garlic and 1/2 teaspoon salt. Add the potatoes and bring to a boil over medium-high heat, stirring occasionally to prevent the potatoes from sticking to the bottom of the pan. Reduce the heat to medium and simmer until the potatoes are tender but still slightly firm, about 8 minutes.
- Remove the saucepan from the heat and, using a slotted spoon, transfer half the potatoes to a buttered 9-by-13-inch baking dish; arrange the potatoes in an even layer. Sprinkle with half the cheese and the cayenne; season with salt and pepper to taste. Repeat with the remaining potatoes and sprinkle with the remaining cheese. Pour the heavy cream evenly over the top. Bake the scalloped potatoes until golden and crisp on top, 40 to 45 minutes. Let stand for 5 minutes before serving.
- Try these worldly variations on the classic. French: Layer fresh tarragon into the potatoes and add a heaping spoonful of grainy mustard to the heavy cream. Greek: Substitute goat cheese for the gruyere and sprinkle a little grated lemon peel and chopped fresh oregano between the potato layers. Spanish: Add thinly sliced or diced chorizo and chopped piquillo peppers or pimientos to the mix.
