Step-by-Step Instructions

Prepare the Yeast Mix:

Pour lukewarm milk into a bowl and stir in the sugar and instant yeast. Let it rest for about ten minutes until bubbles appear on top showing the yeast is active.

Make the Dough:

Mix flour and salt in a large bowl. Add in the milk-yeast mixture and vegetable oil. Knead with a mixer and dough hook for five minutes until the dough is smooth and pulls away from the bowl edges.

Let the Dough Rise:

Lightly grease a big bowl. Place your dough in and turn it so it is coated in oil. Cover and let rise in a warm spot for about forty five minutes until it doubles in size.

Prep the Onion Filling:

Peel and finely slice the onions into thin rings. Cut the bacon into small cubes so it crisps up evenly.

Cook Onion and Bacon:

Heat a tablespoon of oil in a large pan. Fry the bacon over medium heat until crisp. Add onions. Stir well and cook gently for about ten minutes until the onions are tender and translucent. Slow cooking brings out their sweetness.

Mix Filling and Season:

Allow the onion mixture to cool slightly. In a separate bowl whisk together the sour cream and eggs until smooth. Stir egg-sour cream mix into the warm onions and bacon. Add caraway plus a little salt and pepper.

Shape the Dough:

Preheat your oven to two hundred degrees Celsius. On a floured surface knead and roll out the risen dough into a rectangle to fit your baking tray. Press it into the tray and form a small rim on the edges to hold the filling.

Bake the Zwiebelkuchen:

Pour the onion mixture onto the dough base. Smooth to the edges. Bake for about thirty five minutes until the edges are golden brown. Let it cool before slicing.

Garnish and Serve:

Finish with plenty of chopped chives once the Zwiebelkuchen has cooled a bit. Serve warm or room temperature.

Onions are the real star here. I never realized how much natural sweetness they bring until I tasted my first slice as a child at a fair in southern Germany. Now I always use extra onions for that melt in your mouth caramelized layer.

Storage Tips

Store leftover Zwiebelkuchen in an airtight container in the fridge. It will keep best for three days. For longer storage you can cut into slices and freeze. Freeze in a sealed container for up to three months then thaw at room temperature. To refresh just pop into a hot oven for five minutes and you will crisp up the crust nicely again.

Ingredient Substitutions

For a vegetarian version simply skip the bacon and toss in some thinly sliced leeks for extra flavor. If you do not have caraway use a pinch of dried thyme or leave it out for a milder taste. Store bought pizza dough or puff pastry can save time and still gives a tasty result if you are in a hurry.

Serving Suggestions

Zwiebelkuchen is lovely as a lunch with salad or as part of a buffet. In Germany it is often served with a glass of young white wine or fresh apple juice in autumn. It is just as at home at a picnic as at the dinner table with a light soup.
