Ingredients You’ll Need
Don’t be intimidated by the list—this recipe relies on simple, classic ingredients that come together to deliver layers of texture and flavor. Each ingredient plays a key role, from the creamy richness of the butter to the delicate rise provided by yeast, creating the perfect foundation for the unforgettable filling.
- 1 ¾ cups all-purpose flour: The backbone of your dough, it should be measured carefully to ensure the perfect crust texture.

- â…” cup lukewarm milk: Activates the yeast and tenderizes the dough.
- 4 medium yellow onions (about 500 grams): Sweet and aromatic, they are the star of this pie.
- ¼ cup butter (for cooking onions): Adds richness and helps caramelize the onions gently.
- 1 tablespoon all-purpose flour: Thickens the onion filling for perfect consistency.
- 2 large eggs: Bind the filling and provide richness.
- â…“ cup heavy cream: Makes the filling velvety smooth and indulgent.

How to Make German Onion Pie (Zwiebelkuchen) Recipe
Step 1: Prepare the Dough
Start by waking up the yeast. In a small bowl, combine the packet of active dry yeast with sugar and a little bit of lukewarm milk. Let it sit until it becomes frothy—this usually takes about 5 minutes and is a telltale sign that your yeast is active and ready to go. This step is super important because it ensures your dough will rise beautifully.
Step 2: Knead and Rise the Dough
Next, mix the remaining lukewarm milk with all-purpose flour, butter, and salt. The butter should be softened but not melted, lending a tender crumb. Knead this mixture for around 5 minutes until smooth and elastic—don’t rush this; a well-kneaded dough makes all the difference. Cover it with a clean towel and let it rise in a cozy spot until it doubles in size, which usually takes an hour to an hour and a half.
Step 3: Cook the Onions
While the dough rises, peel and slice your yellow onions into thin rings. Heat butter in a large skillet over medium heat and gently cook the onions until they become soft and translucent. This slow cooking ensures the onions release their natural sweetness—the foundation of your filling’s flavor. Once they’re tender, stir in a tablespoon of flour to help thicken the mixture and season with salt. Then give it a bit of time to cool before moving on.
Step 4: Mix the Filling
In a separate bowl, beat the eggs with the heavy cream to create a smooth, silky custard base for the filling. If you love that extra layer of flavor, this is the moment to sprinkle in the caraway seeds. They might be optional, but I promise they add something special to the character of the pie.
Step 5: Assemble the Pie
Grease your baking dish with butter to prevent sticking. Press the risen dough evenly into the dish, letting it climb about an inch up the sides—this keeps all the luscious filling contained and gives you that classic pie look. If you want a thicker filling, use a smaller pan, but for thinner, crispier edges, a larger pan works great.
Step 6: Layer the Filling
Spread the cooked onion mixture gently over the dough base, making sure to distribute them as evenly as possible so every bite is balanced. Then, slowly pour the egg and cream custard over the onions. Scatter the diced bacon generously on the surface—this will crisp up beautifully during baking and add a smoky contrast that’s absolutely irresistible. If you like, sprinkle a few caraway seeds on top for visual appeal and flavor.
Step 7: Bake the Pie
Slide your pie into the oven preheated to 390°F (200°C) and bake it for 35 to 45 minutes. Keep an eye on it—the goal is a set, custard-like center and a golden-brown crust that looks like it’s begging to be eaten. This is where all your effort transforms into a spectacularly aromatic feast.
Step 8: Cool and Serve
Patience is key! Let the pie cool for at least 10 minutes after baking to let everything set properly. This waiting period makes slicing easier and allows the flavors to meld together beautifully. Then, grab a fork and enjoy this divine treat.
How to Serve German Onion Pie (Zwiebelkuchen) Recipe
Garnishes
Fresh herbs like finely chopped chives or parsley sprinkled on top can add a lovely pop of green and a fresh contrast to the rich filling. A dollop of sour cream on the side also complements the savory flavors perfectly, offering a creamy tanginess that brightens every bite.
Side Dishes
German Onion Pie is wonderfully satisfying on its own, but if you want to round out the meal, consider serving it with a crisp green salad drizzled with a light vinaigrette to cut through the richness. A simple cucumber salad with dill and lemon is another traditional pairing that keeps the plate refreshing and balanced.
Creative Ways to Present
If you’re hosting, try making mini versions of German Onion Pie (Zwiebelkuchen) Recipe in muffin tins for charming individual servings. This not only makes portion control easy but also adds an element of fun to your spread. Another idea is serving it alongside a flight of German white wines or crisp apple ciders to elevate the whole experience.
Make Ahead and Storage
Storing Leftovers
Once cooled completely, store your leftover onion pie in an airtight container in the refrigerator. It will keep well for up to 3 days, and the flavors actually develop more depth as it sits.
Freezing
If you want to save some for later, wrap the cooled pie tightly in plastic wrap and then in aluminum foil before freezing. It’s best to consume within a month for optimal taste and texture. When ready to enjoy, thaw overnight in the fridge.
Reheating
To reheat, bake slices in a preheated oven at 350°F (175°C) for about 10 to 15 minutes until warmed through and the crust regains its crispness. Avoid microwaving if you want to preserve that lovely texture!
FAQs
What type of onions work best for Zwiebelkuchen?
Yellow onions are traditionally used because they have a natural sweetness and a mellow flavor when cooked. They caramelize nicely, which brings out the best in this pie.
Can I make this pie without bacon?
Absolutely! While bacon adds a smoky flavor and crunch, you can omit it for a vegetarian version. Adding a pinch more salt or a smoked paprika can help mimic that depth if you like.
Is caraway seed necessary?
Caraway seeds are optional but highly recommended for authenticity. They add a subtle earthiness and a hint of anise-like aroma that many find irresistible in traditional German recipes.
How do I know when the dough has risen enough?
The dough should roughly double in size and look puffy. A gentle poke with your finger should leave an indentation that slowly fills back in, meaning it’s perfectly risen and ready for the next step.
Can I use active dry yeast straight into the dough?
It’s better to proof the yeast first with sugar and warm milk as the recipe states. This ensures the yeast is alive and will give your dough a reliable rise, leading to a lighter crust.

Instructions
- Prepare the Dough: In a small bowl, combine the yeast and sugar with a small amount of the lukewarm milk. Let it sit until frothy, about 5 minutes, to activate the yeast.
- Mix and Knead Dough: In a mixing bowl, combine the remaining lukewarm milk with flour, butter, and salt. Knead the mixture for 5 minutes until a smooth dough forms.

- Cook Onions: Peel and slice the onions into rings. In a large skillet over medium heat, cook the onions in butter until they become soft and translucent, about 10 minutes. Stir in the flour and cook briefly. Remove from heat and allow to cool slightly. Season with salt to taste.
- Prepare Egg Mixture: Beat the eggs and heavy cream together in a bowl. If using, stir in the caraway seeds now for added flavor.
- Assemble the Pie: Press the risen dough evenly into the greased baking dish, extending it about 1 inch up the sides. This helps contain the filling and creates a nice crust edge.

- Bake: Place the assembled pie in the middle rack of the oven preheated to 390°F (200°C). Bake for 35 to 45 minutes until the center is set and the crust is golden brown and crisp.
- Cool and Serve: Allow the pie to cool for at least 10 minutes to set properly before slicing and serving. This resting period enhances flavor and texture.

- Ensure the milk is lukewarm (not hot) to properly activate the yeast without killing it.
- This pie pairs exceptionally well with a light green salad or a glass of Riesling wine.
