Ingredients
- Salt
- 3 pounds small potatoes (such as red or Yukon gold), sliced 1/8 inch thick
- 2 Tbsp unsalted butter, plus more for buttering dish
- 10 medium leeks white and light-green parts only, halved lengthwise and cut crosswise into 1-inch pieces (washed thoroughly)
- 4 garlic cloves, thinly sliced
- 2 cups heavy cream
- 1 cup milk
- 1/4 cup chopped fresh parsley, for garnish
Preparation
Step 1
1. Preheat oven to 375 degrees. In a large pot of salted boiling water, parboil potatoes for 5 minutes. Drain potatoes well and set aside.
2. In a large skillet, heat butter over medium heat. Saute leeks and garlic until leeks are tender, about 7 minutes. Set aside.
3. In a buttered 9-by-13-inch baking dish, arrange half of reserved potatoes in an overlapping pattern. Pour 1 cup cream and 1/2 cup milk over top and sprinkle with 1 teaspoon salt. Top with reserved leeks and arrange remaining potatoes. Pour remaining cream and milk over potatoes and sprinkle with 1/2 teaspoon salt. Bake until potatoes are tender, top of gratin is golden brown, and most of cream and milk have been absorbed, about 45 minutes. Garnish with parsley.
