Allgau Specialty Onion Cake – Zwiebelkuchen

The region Allgäu of the South is a popular vacation destination for all seasons. The region is known for their good food specialties and milk products as well. Popular is the Allgäuer Bergkäse” a cheese that is made in the mountains. Today learn how to make the Allgau Specialty Onion Cake – it’s a flat tart topped with onions, bacon (Speck) and cream. The original recipe is using the popular cheese from the Allgäu mountains and it is called “Bergkäse”. Unfortunately this cheese is not available in the USA or if any, you can find it in special cheese stores. We recommend to use cheese like Emmenthaler, Gruyere or a flavorful hard cheese; we don’t recommend to use American cheese. Happy Cooking!
