Lightly flour the bottom of a 9-inch pie or quiche pan and fit crust into the pan all the way up to the edge. Lightly prick the bottom and sides of the pastry 1 1/2 inches apart.
Step 3
Cut parchment paper to fit the bottom of the pan place parchment on the pastry and put pie weights or dried beans on top of the parchment.
Step 4
Bake on the center rack of the preheated oven for 10 minutes. Place pan on a wire rack remove the weights and the paper and allow to cool completely about 30 minutes.
Step 5
Meanwhile fill a large bowl with ice and cold water. Bring a large pot of lightly salted water to a boil. Add broccoli and cook uncovered until softened about 5 minutes. Drain in a colander and immediately immerse in ice water for several minutes to stop the cooking process. Drain.

Set quiche on a baking sheet and place on the center rack of the oven. Bake until egg mixture is set 45 to 50 minutes. Insert a knife in the center of the quiche to test for doneness; quiche is done when the knife comes out clean. Pace pan on a wire rack to cool for about 10 minutes. Serve warm.
