This easy, casserole-style dish is rich with buttery leeks and Russet potatoes.
2 large leeks, white and light green parts only
1 tablespoons butter
⅛ cup water
¼ teaspoon sea salt
3-4 Russet potatoes, peeled and cut into small cubes
½ teaspoon sea salt
1 cup chicken broth, or enough to cover potatoes in a sauce pan
¼ cup cream
3 tablespoons butter
Sea salt and fresh ground pepper
1. To prepare confit, wash leeks and quarter them lengthwise, and then cut crosswise into quarter-inch pieces. In a medium sauce pan with a lid, melt butter, then add leeks, water, and salt and cook covered on medium low heat for 20 to 25 minutes, stirring frequently. When soft, remove the lid and cook a few more minutes until most of the liquid has evaporated. Set aside.
2. Boil the potatoes in the chicken broth until fork tender. Drain, reserving about ¼ cup of the broth. Mash the potatoes with a ricer or in a stand mixer.
3. Preheat oven to 350°. Warm the cream, broth and butter and mix into the potatoes. Add more cream if mixture seems dry. Season generously with salt and pepper.
4. Stir in 3 tablespoons of the leek confit and salt to taste, and spread the mixture into a buttered shallow 9- by 11-inch baking dish. Bake in the oven for 40 minutes, or until golden brown on top. Serve warm. (The casserole can be made the night before and refrigerated before being finished in oven.)
