How to Make German Onion Pie (Zwiebelkuchen) Recipe
Step 1: Prepare the Dough
Start by waking up your yeast. In a small bowl, combine the active-dry yeast with sugar and a splash of lukewarm milk. Let this mixture sit for about 5 minutes until frothy and bubbly—it’s a sign your yeast is alive and ready. Then, combine the flour, butter, salt, and remaining milk, kneading everything together until you get a smooth, elastic dough. Cover it and let it rise in a warm spot until it has doubled in size. This process builds a soft and airy base that will carry all those delicious flavors.
Step 2: Cook the Onions
While the dough is puffing up, peel and slice your yellow onions into rings. Gently cook them in butter over medium heat until they turn soft and translucent, releasing their natural sweetness. Stir in a little flour to help thicken the mixture, and let it cool down to maintain that perfect texture. Don’t rush this step—taking your time on the onions gives your pie depth and incredible flavor.
Step 3: Prepare the Filling
Mix together the eggs and heavy cream in a bowl until smooth and combined. If you love that traditional hint of spice, stir in the caraway seeds now. This creamy mixture is what sets this pie apart, blending beautifully with the softened onions and crispy bacon for a rich, comforting filling.
Step 4: Assemble the Pie
Butter your baking dish to prevent sticking and press the risen dough evenly into the pan, pushing it about an inch up the sides to create a nice crust edge. Spread the cooled onion mixture over the dough, then carefully pour the egg and cream mixture on top. Scatter diced bacon over the surface to add a smoky crunch that contrasts the sweet onions. Sprinkle extra caraway seeds if you’re feeling traditional.
Step 5: Bake to Perfection
Place the assembly in a preheated oven at 390°F (200°C) and bake for 35 to 45 minutes. You’ll want to watch as the crust turns a lovely golden brown and the custard filling sets just right. The aromas wafting from your oven at this point are part of what makes this recipe such a joy. When done, let the pie cool for at least 10 minutes before cutting—it allows the filling to firm up and makes serving easier.

This hearty pie bakes to golden perfection, offering a rich blend of textures and flavors that is perfect for festive occasions or cozy meals.
Ingredients
Dough
- 1 ¾ cups all-purpose flour
- ¼ cup butter
- 1 packet active-dry yeast (about 4 grams)
- 1 teaspoon salt
- 1 teaspoon granulated sugar
- ⅔ cup lukewarm milk
Onion Filling
- 4 medium yellow onions (about 500 grams)
- ¼ cup butter (for cooking onions, plus additional for greasing)
- 1 tablespoon all-purpose flour
- Salt, to taste
Egg Mixture
- 2 large eggs
- ⅓ cup heavy cream
- 1 teaspoon caraway seeds (optional)
Toppings
- 2 slices thick-cut bacon, diced
- Additional butter for greasing the baking dish
Instructions
- Prepare the Dough: In a small bowl, combine the active-dry yeast and granulated sugar with a portion of the lukewarm milk. Let the mixture sit for about 5 minutes until it becomes frothy, indicating the yeast is active.
- Mix and Knead Dough: In a larger bowl, mix the remaining lukewarm milk with flour, butter, and salt. Add the yeast mixture and knead the dough thoroughly for about 5 minutes until smooth. Cover and place it in a warm area to rise until doubled in size, roughly 1 to 1 ½ hours. Prepare your baking dish by greasing it with butter.
- Prepare the Onions: Peel and slice the yellow onions into rings. Heat butter in a large skillet over medium heat and cook the onions until they are soft and translucent, about 10 minutes. Stir in 1 tablespoon of flour to bind, then season with salt to taste. Allow the onion mixture to cool.
- Make Egg Mixture: In a bowl, beat together the eggs and heavy cream until smooth. Add caraway seeds if using, to incorporate their distinctive flavor.
- Assemble the Pie: Press the risen dough evenly into the greased baking dish, extending it about 1 inch up the sides. Spread the cooled onion mixture over the dough evenly. Pour the egg and cream mixture on top of the onions. Scatter diced bacon evenly over the surface and sprinkle with additional caraway seeds if desired.
- Bake: Preheat the oven to 390°F (200°C). Place the pie in the center of the oven and bake for 35 to 45 minutes, until the filling is set and the crust turns golden brown.
- Cool and Serve: Remove the pie from the oven and allow it to cool for at least 10 minutes before slicing and serving. This resting time helps the filling to set properly for clean slices.
Notes
- Using lukewarm milk is crucial for activating the yeast properly.
- If you prefer a vegetarian version, omit the bacon from the topping.
- Caraway seeds add authentic flavor but can be left out if unavailable or undesired.
- The pie is best enjoyed warm or at room temperature.
- For a thinner crust, use a larger baking pan than 9.5 inches.
