Onion tart, or “Zwiebelkuchen,” is a beloved dish in German cuisine that brings comforting flavors and rustic charm to any table. This savory tart is traditionally made with a flaky crust, tender caramelized onions, and a creamy filling, making it a perfect choice for gatherings or a cozy dinner at home.
Ingredients:
For the crust:
2 cups allpurpose flour
1/2 cup unsalted butter, chilled and cubed
1/2 teaspoon salt
45 tablespoons cold water
For the filling:
3 large onions, thinly sliced
2 tablespoons olive oil
2 eggs
1 cup sour cream
1 cup shredded cheese (such as Gruyère or Emmental)
Salt and pepper to taste
Fresh thyme or chives for garnish (optional)
Home Cooking Method:
1. Prepare the crust:
In a large mixing bowl, combine the flour and salt.
Add the chilled butter and use a pastry cutter or your fingers to work it into the flour until the mixture resembles coarse crumbs.
Gradually add cold water, one tablespoon at a time, mixing until the dough comes together.
Shape the dough into a ball, wrap it in plastic, and refrigerate for at least 30 minutes.
2. Cook the onions:
In a skillet, heat the olive oil over medium heat.
Add the sliced onions and cook, stirring occasionally, until they are soft and golden brown, about 1520 minutes. Season with salt and pepper, and set aside to cool.
3. Prepare the filling:
In a mixing bowl, whisk together the eggs and sour cream until smooth.
Stir in the cooked onions and shredded cheese. Adjust seasoning with salt and pepper.
4. Assemble the tart:
Preheat your oven to 375°F (190°C).
Roll out the chilled dough on a lightly floured surface to fit a 9inch tart or pie pan.
Press the crust into the pan, trimming any excess dough.
Pour the onion and cheese mixture into the prepared crust, spreading it evenly.
5. Bake the tart:
Place the tart in the preheated oven and bake for about 3035 minutes, or until the top is golden and set.
Remove from oven and let it cool slightly before slicing.
Serving:
Onion tart can be enjoyed warm or at room temperature, making it a versatile dish for lunch, dinner, or as a tasty snack. Garnish with fresh herbs for an added pop of flavor. Pair it with a crisp salad or some seasonal vegetables, and you have a delicious representative of German culinary tradition right at home.
