Instructions
Caramelize onions
- 1Heat butter in a large skillet over medium heat; add thinly sliced onions and a pinch of salt.
- 2Cook onions slowly, stirring occasionally, for 20–25 minutes until soft, deeply golden and sweet; reduce heat if browning too fast.
- 3If using bacon, fry diced bacon in a separate pan until crisp, drain and set aside; stir caraway seeds into onions in the last minute of cooking.
Assemble and bake
- 1Preheat oven to 200°C (400°F). Line a rimmed sheet pan (about 30x40 cm) with parchment.
- 2Unroll the thawed puff pastry onto the prepared pan, gently pressing to fit and trimming any excess; dock the pastry lightly with a fork to prevent excessive puffing.
- 3In a bowl, whisk together sour cream, beaten eggs, salt and black pepper until smooth; fold in chopped herbs and the reserved crisp bacon if using.
- 4Spread the caramelized onions evenly over the docked pastry, then pour the sour cream and egg mixture on top, smoothing to an even layer.
- 5Bake in the preheated oven for 20–25 minutes, until the filling is set and puff pastry is golden and crisp at the edges.
- 6Let the Zwiebelkuchen cool for 5–10 minutes, then cut into squares and serve warm or at room temperature.

Tips
- Slice onions thinly and salt them lightly to draw out moisture for even, quicker caramelization.
- Cook onions low and slow for best sweetness; patience yields deep golden color and flavor.
- Serve warm squares with a crisp green salad and a chilled dry German white wine for balance.
