Alsatian Quiche Lorraine – Savory Pie with Eggs, Cheese, Onions and Mushrooms

The Alsace-Lorraine valley straddles the Rhine river between northwest France and northeast Germany. Quiche is considered a classically French dish but actual originated across the river in Germany during medieval times. This region has changed hands throughout history. The last was when it was rewarded back to the French as reparations for WWI. To get technical, a Quiche Lorraine doesn’t typically have onions. Add onions and you’ve got quiche alsacienne. Add both onions and mushrooms and you get the magnificent hybrid below, my Hungry Traveler’s version of the classic.
