This Authentic German Onion Pie (Zwiebelkuchen) is one of Germany’s most beloved traditional dishes, especially popular in the fall during wine season. Imagine a flaky, buttery crust filled with sweet caramelized onions, smoky bacon, and a creamy egg mixture—it’s savory, hearty, and deeply comforting. I first tried this recipe while visiting friends in southern Germany, and after one bite, I understood why it’s such a cherished classic. The aroma of onions gently cooking with bacon fills your kitchen, and the pie itself tastes like pure comfort with every bite. Serve it warm with a glass of crisp white wine or Federweißer (young wine) for an authentic German experience right at home.

Description
Authentic German Onion Pie, known as Zwiebelkuchen, is a traditional savory pie from southern Germany made with caramelized onions, smoky bacon, and a creamy egg custard baked in a buttery crust. It’s rich, hearty, and perfect for fall gatherings or cozy dinners.
Ingredients
- 1 9-inch pie crust (homemade or store-bought)
- 4 large yellow onions, thinly sliced
- 4 slices thick-cut bacon, diced
- 2 tablespoons butter
- 1 tablespoon all-purpose flour
- 3 large eggs
- 1 cup sour cream
- 1/2 teaspoon salt
- 1/4 teaspoon black pepper
- 1/4 teaspoon nutmeg (optional, traditional addition)
- 1 teaspoon caraway seeds (optional, for garnish)
- 1 tablespoon chopped fresh parsley (optional, for garnish)
Instructions
- Preheat oven to 375°F (190°C). Roll out the pie crust and fit it into a 9-inch tart or pie pan. Prick the bottom with a fork and set aside.
- In a large skillet, cook diced bacon over medium heat until crisp. Remove bacon and drain on paper towels, leaving about 1 tablespoon of fat in the skillet.
- Add butter to the pan, then add the sliced onions. Cook over medium-low heat for 10–15 minutes, stirring occasionally, until soft and golden.
- Sprinkle flour over the onions and stir for 1 minute to combine. Remove from heat and let cool slightly.
- In a large bowl, whisk together eggs, sour cream, salt, pepper, and nutmeg.
- Stir the onion mixture and bacon into the egg mixture until evenly combined.
- Pour the filling into the prepared pie crust, spreading evenly.
- Sprinkle with caraway seeds if desired, then bake for 35–40 minutes, until the top is golden and the center is set.
- Let cool for 10 minutes before slicing. Garnish with chopped parsley and serve warm or at room temperature.
Notes
- Traditionally enjoyed during fall wine festivals in Germany, especially with a glass of Federweißer (young wine).
- For a vegetarian version, omit the bacon and sauté onions in olive oil or butter.

Ingredients
(Tip: You can find the complete list of ingredients and their measurements in the recipe card below.)
For the Dough:
- 2 cups all-purpose flour
- 1 teaspoon salt
- 1 teaspoon sugar
- 1 packet (2¼ teaspoons) active dry yeast
- ¾ cup warm milk (about 110°F)
- 3 tablespoons unsalted butter, softened
For the Filling:
- 4 large onions, thinly sliced
- 5 ounces bacon, diced
- 1 tablespoon butter or oil
- 3 large eggs
- 1 cup sour cream (or half sour cream, half heavy cream)
- 1 tablespoon all-purpose flour
- 1 teaspoon caraway seeds (optional, but traditional)
- Salt and freshly ground black pepper to taste
- A pinch of nutmeg
Directions
1. Prepare the Dough
In a small bowl, mix the warm milk, sugar, and yeast. Let it sit for about 5–10 minutes until frothy. In a large bowl, combine the flour and salt. Add softened butter and the yeast mixture, then knead until you get a smooth, elastic dough. Cover and let it rise in a warm place for about 45 minutes, or until doubled in size.
2. Prepare the Filling
While the dough rises, heat a large skillet over medium heat. Add the diced bacon and cook until it begins to render fat. Add the butter and sliced onions, then cook slowly, stirring often, for about 15–20 minutes until the onions are soft and translucent (not browned). Remove from heat and let cool slightly.
3. Combine the Cream Mixture
In a separate bowl, whisk together eggs, sour cream, flour, nutmeg, salt, pepper, and caraway seeds if using. Add the cooled onion and bacon mixture, stirring until well combined.
4. Assemble the Pie
Preheat the oven to 375°F (190°C). Roll out the dough on a lightly floured surface to fit a 9-inch tart or pie pan, pressing it up the sides. Pour the onion mixture into the crust and spread evenly.
5. Bake
Bake in the preheated oven for 40–45 minutes, or until the filling is set and the top is golden brown. Let it cool for 10 minutes before slicing and serving.
