Ingredients:

For the crust

• 9 ounces (2 cups) all-purpose flour

• 2 teaspoons granulated sugar

• 1 teaspoon kosher salt

• 8 ounces (1 cup) cold unsalted butter, cut into 1/2-inch cubes

• 4-6 tablespoons ice water

For the filling

• 1 ounce (2 tbsp.) unsalted butter

• 1/2 medium red onion, thinly sliced crosswise (1 cup)

• 24 frozen artichoke heart quarters, thawed

• 4 large eggs

• 1 cup heavy cream

• 1/2 cup whole milk

• 1 tablespoon roughly chopped fresh dill

• Kosher salt and freshly ground black pepper

• Pinch nutmeg

• 6 ounces hot-smoked trout, skin removed and roughly broken into 1/2-inch pieces (1 cup)

• 4 ounces fresh goat cheese, crumbled (3/4 cup)

Procedure:

Make the crust

1. In a stand mixer fitted with the paddle attachment, mix the flour, sugar, and salt on low speed. Add the butter and mix until the largest pieces are the size of peas. With the mixer still on low, add the ice water 1 tablespoon at a time until the dough just begins to come together— you may not need all the water. Transfer the dough to a piece of plastic and shape it into a disk. Wrap in the plastic and refrigerate for at least 30 minutes.

2. Roll the dough on a lightly floured surface into a 15-inch circle about 1/4 inch thick. Transfer to a 9-inch springform pan and press the dough into the bottom and up the sides, pressing any pleats flat against the sides. With scissors, unevenly snip any dough that overhangs the rim, to make a jagged edge. Prick the bottom of the crust all over with a fork. Freeze for 20 minutes.

3. Position a rack in the center of the oven and heat the oven to 350°F. Line the frozen crust with two overlapping sheets of parchment and fill two-thirds of the way with dried beans. Bake until the sides are set, about 25 minutes. Remove the beans and parchment and bake until the crust just begins to brown lightly, another 8 to 10 minutes. Remove from the oven and let cool on a rack. Meanwhile, raise the oven temperature to 400°F.

Make the filling

1. Melt the butter in a 10-inch sauté pan over medium-high heat. Add the onion and cook, stirring occasionally, until soft and turning translucent, about 3 minutes. Add the artichoke hearts and cook until softened and slightly browned, another 3 to 4 minutes. Remove the pan from the heat.

2. Beat the eggs in a medium bowl with the cream, milk, 1 teaspoon of the dill, 1/4 teaspoon of salt, 1/4 teaspoon of pepper, and the nutmeg.

3. Put the springform pan on a rimmed baking sheet. Pour about half of the egg mixture into the crust. Bake in the oven until the filling is partially set (it will still be slightly runny), about 20 minutes.

4. Scatter half of the onion and artichoke mixture over the partially set egg mixture. Distribute half of the trout and goat cheese on top. Pour on the remaining egg mixture and then scatter the remaining onions, artichokes, trout, and goat cheese over the egg. Sprinkle the remaining dill over the top.

5. Bake until the center is just set (use a paring knife to peek), another 40 to 50 minutes. Check about halfway through baking; if the crust seems to be browning too fast, shield it with strips of foil. Cool slightly on a wire rack.

6. To unmold, remove the springform ring and loosen the quiche from the pan’s bottom by running a thin-bladed knife between the two. Slide the quiche off its base onto a serving plate. Serve warm or at room temperature, cut in wedges.
