Simple ingredients -- potatoes, eggs, cream, and gravlax, which is salmon cured with salt and sugar -- add up to a dish that manages to be homey and elegant at the same time. A simple salad of lightly dressed lettuce sets it off beautifully.

- Prep Time 40 minutes
- Total Time 2 hours 40 minutes
- Serves 10
- 3 pounds medium russet potatoes
- 1 tablespoon coarse salt
- 1/4 cup fresh dill, chopped, and stalks reserved
- 1/2 stick unsalted butter, divided, plus more for dish
- 1 medium onion, chopped (about 1 1/2 cups)
- 1 1/4 pound gravlax (sliced 1/8 inch thick)
- Freshly ground white pepper, for sprinkling
- 6 large eggs, lightly beaten
- 1 1/2 cups half-and-half
- 1 1/2 cups heavy cream
- 6 tablespoons unsalted butter, softened
- 1 tablespoon chopped fresh dill
- 1/4 teaspoon coarse salt
- Casserole: Place potatoes in a large pot, and cover with 2 inches water. Add salt and dill stalks. Bring to a boil, reduce heat, and simmer until you can just pierce potatoes with a fork, 7 to 10 minutes. Pour off water, and discard dill stalks. Place paper towel across top of pot (not directly on potatoes), and let potatoes steam and cool 1 hour.
- Preheat oven to 350 degrees. Peel potatoes, and cut into 1/4-inch-thick slices. Melt 3 tablespoons butter in a saute pan, and saute onion until softened, about 10 minutes.
- Butter a 9-by-13-inch baking dish. Layer potatoes and gravlax, beginning and ending with potatoes, sprinkling each layer with chopped dill, sauteed onion, and pepper.
- Whisk together eggs, half-and-half, and cream; season with pepper. Pour egg mixture over potatoes and gravlax, and dot with remaining 3 tablespoons butter. Bake until golden on top and bubbling around the edges, 45 minutes to 1 hour.
- Dill butter: Meanwhile, mix all ingredients together, and roll into a log.
- Let casserole cool slightly, 5 to 10 minutes, and serve warm with dill butter.
