Remove second sheet and fit crust into pan, trimming edges evenly.
Transfer to freezer for 15 minutes.
Heat oven to 425 degrees.
Line frozen crust with foil and weight with dried beans or pie weights.

Lower oven temperature to 400 degrees.
For filling, melt butter with oil in a large, nonstick skillet over medium heat.
Add onions and stir to coat with butter and oil.
Sprinkle with salt and mix well.
Cook, stirring often, until onions are softened, about 10 minutes.
Add Reisling and continue cooking, until onions are limp and only about 1/4 cup liquid remains.
Remove from heat and cool slightly.
Transfer onions to a mixing bowl.
