  • 1 tablespoon butter
  • 2 teaspoons olive oil
  • 4 sweet onions thinly sliced
  • 1 teaspoon salt
  • 1 teaspoon sugar
  • 6 ounces Roth Butterkäse grated
  • 2 sheets frozen puff pastry thawed
  • 2 teaspoons minced parsley


  • Heat a 12 inch heavy bottomed skillet over medium heat. Add the butter and oil to coat the bottom.
  • Add the onions to the skillet and stir well to coat in the butter and oil. Cook 10 minutes over medium low heat. 
  • Sprinkle the onions with the salt and sugar and stir well. 
  • Continue cooking for 50 minutes, stirring every 5 to 10 minutes, until the onions are soft and browned. You may need to reduce the heat to keep the onions from burning. If the onions start to look dry while cooking, add 2 tablespoons of water to the pan and stir.
  • When onions are finished cooking, unroll the puff pastry sheets and top each sheet with the cheese, onions, and parsley. Roll the sheets up jelly-roll style.
  • Slice into 8 rounds per sheet with a serrated knife. 
  • Place on a parchment lined baking sheet and bake at 400 degrees for 15 minutes. 
  • Serve immediately.
