Authentic German Zwiebelkuchen recipe from the heart of Swabia in southern Germany! Loads of caramelized onions and savory bacon are packed into this incredibly delicious pie that has been a favorite for generations!
What is Zwiebelkuchen?
Autumn in Germany means a great many things to me, among them the brilliance of leaves changing color, harvested grapes from scenic hillsides, and Zwiebelkuchen, one of my favorite baked goods. This directly translates to “onion cake” but it’s actually a delicious savory pie. Growing up in southern Germany, I always looked forward to the Fall, one reason being that it meant enjoying this incredibly delicious German Zwiebelkuchen. Another reason – grape season. Traditionally Zwiebelkuchen is enjoyed with a glass of Federweisser, or grape must. Not being an alcohol drinker, I always enjoyed it with a glass of delicious freshly squeezed grape juice. During the Fall, right after the grape harvests, you can find roadside stands selling it in large jugs and never did a year go by that we didn’t stop at least once to load up. There are a few varieties of Zwiebelkuchen, depending which region you’re in. Some are flat and cut into squares with a thinner layer of the topping, others are thicker and deeper like pie. This version is from Swabia where I grew up. A favorite past-time is going to the Black Forest in the Fall and enjoying a slice of Schwäbischer Zwiebelkuchen at a Cafe, made with delicious local Black Forest bacon. Swabian Zwiebelkuchen is typically round and deep, like quiche, though the flat varieties can also be found in bakeries throughout southern Germany. But whatever the shape, traditional Zwiebelkuchen always consists of yeast dough, topped with buttery caramelized onions, savory bacon, and a thick creamy base. Often, as in this version, caraway seeds are also included which add a wonderful depth and dimension of flavor. I developed this recipe a few years ago as Autumn set in and I was craving the Zwiebelkuchen I always enjoyed in Germany. If you like onions, butter and bacon, you will love this Zwiebelkuchen, guaranteed!
Zwiebelkuchen Recipe
Let’s get started!
Use good quality bacon with a nice, smoky flavor for best results. Fry the bacon until crispy.
Add the onions and cook for 30-30 minutes until nicely caramelized.
Let the onion mixture cool.
Combine all the filling ingredients in a bowl.
Beat until combined.
Add the onion mixture and stir to combine.
Pour the filling mixture into the prepared crust in a 9 to 10 inch springform (see recipe card below for instructions for preparing the crust). A springform is critical as you will need to release the pie from it. In the pictures I’m using the Cuisinart Chef’s Classic Non-Stick Springform. Another good option is Fat Daddio’s aluminium springform.
Sprinkle with a few caraway seeds.
Bake in the oven preheated to 400 degrees F for 55-60 minutes or until the top is light brown and the center of the pie feels fairly firm to the touch.
Let cool for at least 20 minutes before serving. Can be eaten lukewarm or cold.
Enjoy!
