Preheat oven to 400 degrees F (200 degrees C).
In a small bowl whisk together eggs, half & half and seasonings until combined.
Pour egg mixture over the bacon, cheese and asparagus.
Bake in preheated 400 F. oven for 15 minutes. Then reduce heat, leaving the pie in the oven to 350 degrees F (175 degrees C) and bake for an additional 35 minutes.
The quiche will turn a nice golden brown on top, which should indicate doneness. The center of the quiche should be just set and barely jiggle when moved. It will continue to cook and set once removed from oven.
Remove from oven and allow to sit at least 25 minutes before serving. This quiche is fabulous when cooled to room temperature and can easily be reheated with great results.
