Angie’s Zwiebelkuchen with Puff Pastry crust

Zwiebelkuchen, German onion tart

Zwiebelkuchen is a popular German onion pastry. It is served with Federweissen (a new fermented wine). Those two just go hand in hand.

I developed my own recipe for this onion pastry. The crust can be bought, Puff Pastry dough (Pepperidge Farms) can be found in the freezer isle.
