Buttery Pastry Shell:
2 cups unbleached flour, sifted. Plus more for dusting
1 teaspoon kosher salt
2 sticks chilled unsalted butter cut into 1/4 inch dice
1/4 cup ice water
canola oil for brushing
In the bowl of a standing mixer fitted with the paddle, mix 1 cup of the flour with the salt. At low speed, add the butter pieces a handful at a time. When all of the butter has been added, increase the speed to medium and beat until all of the butter is incorporated. Reduce the speed to low and add the last 1 cup of flour just until blended. Mix in the water just until throughly incorporated. Flatten the pastry on a floured board into an 8 inch disk. Wrap in plastic and refrigerate until chilled at least 1 hour or overnight.
Place the unwrapped pastry on a floured board and roll in out to a 14" to 16" round dusting with flour as needed. Carefully fit it into an oiled 9" springform pan. Pat it into the pan and trim the excess pastry from the top, leaving enough pastry to flute the top. Flute and gently press the top against the edge. Chill the pastry shell for at least 20 minutes.
Preheat the oven to 375 degrees F. Line the pastry shell with a 14" round of parchment paper and fill with dried beans or rice. Place the springform pan on a sheet pan and bake the pastry shell for about 40 minutes or until the fluted edges are lightly browned. Carefully remove the parchment paper with the dried beans. I used a scoop to remove most of the beans before lifting the parchment paper out. Return the shell to the oven and bake for an additional 15 minutes or until the bottom is lightly browned.
Transfer the baking sheet to a rack and let cool. The baked pastry shell can be covered with plastic and left at room temperature overnight if needed.
Quiche Filling:
8 slices of bacon, cubed and fried until crisp and then drained
1 pound of asparagus, trimmed and sliced and blanched in boiling water until crisp tender. Transfer to ice water to retain color. Dry thoroughly before adding to quiche
3/4 cup Swiss cheese
2 cups whipping cream
2 cups of milk
6 eggs
Pinch of nutmeg
Salt and pepper to taste
Scatter 1/4 cup of the Swiss cheese and 1/2 of the bacon and asparagus over the bottom of the pastry shell. In a blender or the bowl of a stand mixer blend together 1 cup of the cream, 1 cup of the milk and three of the eggs with 1 teaspoon of salt, 1/8 teaspoon of pepper and a pinch of nutmeg until frothy, about 1 minute. Pour over the asparagus mixture. Add 1/4 cup of the Swiss cheese and the remaining bacon and asparagus. Blend the remaining cream, milk and eggs until frothy and pour over the top. Add the remaining 1/4 cup of Swiss cheese to the top.
Preheat the oven to 325 degrees F and bake the quiche for about 1 1/2 hours or until the top is nicely browned and the custard is barely set in the center. Let cool in the pan until very warm. Remove springform ring, slice and serve.
