08 -
200 g smoked bacon
09 -
1 tablespoon vegetable oil

# Steps:
01 -
Combine lukewarm milk, instant yeast, and sugar in a bowl. Mix and let sit for 10 minutes until foamy.
02 -
In a large bowl, mix flour and salt. Add the yeast-milk mixture and vegetable oil. Knead with a dough hook for about 5 minutes until a smooth, elastic dough forms.
03 -
Lightly oil a large bowl, place the dough inside, turning to coat. Cover with foil, plastic wrap, or a clean towel. Let dough rise in a warm place for 45 minutes until doubled.
04 -
Peel onions and slice into thin rings. Dice bacon.
05 -
In a large frying pan, heat vegetable oil over medium heat. Fry bacon until crisp, then add onions. Cook gently until onions are soft and translucent, about 10 minutes. Set aside to cool slightly.
06 -
In a bowl, whisk together sour cream and eggs. Stir in ground caraway. Mix this into the cooled onion-bacon mixture. Season with salt and pepper.
07 -
Preheat oven to 200°C. Grease a 30 x 40 cm baking tray with butter or line with parchment paper.
08 -
On a lightly floured surface, knead the risen dough briefly, then roll out to fit the tray. Transfer to the tray, pressing into corners and forming a rim.
09 -
Spread onion filling evenly over the dough. Bake in the preheated oven for 35 minutes or until the surface is golden and set.
10 -
Allow to cool slightly before slicing. Garnish with freshly chopped chives before serving, if desired.
# Notes:
01 -
For a vegetarian adaptation omit bacon and add leeks; cheese or thyme are popular additions.
