Preparation time: 30 minutes
Baking time: 40 minutes
Total time: 1 hour and 10 minutes
Number of servings: 6

Ingredients for the dough:
- 200 grams of flour
- 100 grams of butter (at room temperature)
- 1/2 packet of baking powder
- a pinch of salt
- water as needed (about 4-5 tablespoons)

Ingredients for the filling:
- 700 grams of onion (preferably white or yellow onion)
- 1 medium potato (about 150 grams)
- 3 eggs
- 4 tablespoons of sour cream or 200 ml of milk
- 40 grams of flour
- 80 grams of butter (for sautéing)
- salt and pepper (to taste)
- cumin (optional, for extra flavor)
- fresh dill (for garnish, optional)

Step 1: Preparing the dough
Start by making the dough. In a large bowl, add the flour, baking powder, and salt. Mix the dry ingredients well. Add the butter cut into cubes and knead with your fingers until you get a texture similar to wet sand. It is important that the butter is at room temperature to incorporate easily into the flour.

Gradually add water, one tablespoon at a time, until the dough becomes elastic but not sticky. Form it into a ball, wrap it in plastic wrap, and let it rest in the refrigerator for one hour. This step is essential for obtaining a flaky dough that will roll out easily.

Step 2: Preparing the filling
Meanwhile, it’s time to prepare the filling. Peel and finely chop the onion. Grate the potato using a large grater. In a large skillet, add the butter and let it melt over medium heat. Add the onion and grated potato, stirring constantly to prevent burning. Cook for about 10-15 minutes, until the onion becomes translucent and the potato starts to soften. Allow the mixture to cool slightly.

In a separate bowl, beat the eggs as for an omelet. Add the sour cream or milk and mix well. Incorporate the flour, salt, pepper, and cumin (if using). Once the onion and potato have cooled, combine them with the egg mixture and mix well. Make sure the ingredients are homogeneous.

Step 3: Assembling the tart
Preheat the oven to 180°C. Remove the dough from the refrigerator and roll it out on a lightly floured surface until you obtain a thin sheet. Transfer the dough to a tart pan (about 24 cm in diameter), making sure to cover the edges well. Trim the excess dough from the edges, leaving a little to prevent the filling from leaking.

Carefully pour the onion and egg mixture into the tart crust, ensuring it is evenly distributed.

Step 4: Baking
Place the tart in the preheated oven and bake for 40 minutes, or until the surface is golden and the filling is well cooked. This is a perfect time to prepare a fresh salad or a yogurt sauce with dill to complement the tart perfectly.

Step 5: Serving
Let the tart cool for 10 minutes before cutting it. You can serve it warm or at room temperature. A garnish of freshly chopped dill provides a pleasant contrast and a flavorful note.

Practical tips:
- You can experiment with different types of onions: red onion offers a sweet note, while green onion can add freshness.
- If you want a vegetarian version, you can add vegetables like zucchini or spinach.
- The tart pairs excellently with a glass of white wine or fresh lemonade.
