quiche with carmelized onions, mushrooms, spinach + feta cheese

Jump to Recipe·Print Recipe

It’s June and oh so gloomy outside.  Definitely not a beach day today.  So, what is a girl in Malibu to do on a day like this?  “Bake quiche!” I say.  Quiche is one of those dishes that I really enjoy cooking…and eating. I love to eat it cold, straight out of the fridge. When I make quiche, I cook two at a time, a quiche with carmelized onions, mushrooms, spinach + feta cheese and a quiche lorraine which I will soon share my recipe for. Hubby prefers the quiche lorraine, but I prefer the veggie. Both are equally delectable and super easy to make. Sometimes, I will bake my own pie crust, using a healthier pie dough such as a whole wheat pâte brisée pie crust, or if I’m short on time, I’ll use a purchased frozen pie crust. The choice is yours.

Quiches can be made ahead and are great for potlucks or brunches. They are definitely my go to dish for entertaining and one that pleases just about everyone.

I’m so happy today ended up being cloudy and gray, because hubby and I are sure enjoying our quiche.
