Caramelized Mushroom and Onion Quiche with Goat Cheese and Zaatar

Quiche: Buttery pie crust filled with a savory egg custard.  Ask most people and they’ll tell you it’s a French dish, but it actually originated in Germany.  The word “quiche” coming from the German word “kuchen”, or cake!  Regardless of the origin, we love quiche for its versatility and savory deliciousness. 

This Caramelized Onion and Mushroom Quiche with Goat Cheese and Zaatar may sound fancy, but it’s really a breeze to make. Ready-made pie crust takes the work out of this brunch favorite while a boost of flavor comes from zaatar – a zesty, aromatic spice blend from the Middle East. Zaatar ingredients can vary, but we recommend one that consists of only the zaatar herb (wild thyme), sumac, sesame seeds, and little to no sea salt (never any fillers or artificial ingredients). These herbs and spices really brighten up this quiche and help to balance out the richness of the eggs and pie crust. 

Elegant enough for a Christmas Day brunch, yet simple enough for a quick, weeknight dinner, we hope you’ll give this unique quiche recipe a try!
