Tarte à l'oignon

Tarte à l'oignon is a fragrant, savory onion tart from the Alsace region in France. Essentially, it is an open-face pie that is filled with a rich and flavorful custard of eggs, bacon, and onions. Although it is a cousin to the famous quiche Lorraine, it is not as deep as traditional quiches. The most popular story about the origin of the onion tart says that it was a baked good with which the bakers would test the heat of the ovens, depending on the time it took to bake it. If the tart was baked in a certain amount of time, that meant that the oven was hot enough for bread to be baked in it. Today, the tart is enjoyed throughout France, with the sweetness of the onions contrasting with the salty, smoky bacon. The whole dish is typically spiked with thyme, while anchovies are sometimes used in order to accentuate the flavors even more.
