Preheat oven to 425 degrees F. Spray a 9" pie plate with cooking spray. Squeeze as much liquid out of thawed potatoes as possible. To a medium bowl, add squeezed potatoes, oil and 1/4 cup cheese. Season with salt and pepper and toss to combine.
Firmly press potato mixture into prepared pie plate. Bake until potatoes are starting to brown, 25 to 30 minutes. Let cool slightly. Reduce oven to 350 degrees F.
Meanwhile, microwave broccoli according to package directions and drain very well. In a large bowl, combine eggs, milk and mustard. Whisk together until smooth. Season with salt and pepper.
Add broccoli and 3/4 cup cheese to crust. Slowly add custard over filling. Sprinkle remaining 1/4 cup cheese over the quiche. Bake until filling is just set, 35 to 45 minutes. Let quiche cool 10 minutes before serving.
