Preparation time: 30 minutes
Baking time: 30-40 minutes
Total time: 1 hour and 10 minutes
Servings: 6-8

Ingredients:

For the dough:
- 250 g flour
- 50 g butter (melted but not hot)
- 12 g fresh yeast
- 1 teaspoon salt
- 1 teaspoon sugar
- 150 ml lukewarm milk
- Dried thyme (optional, for flavor)

For the filling:
- 500 g onion (white or yellow, depending on preference)
- 50 g butter (for sautéing the onion)
- 1 tablespoon flour
- 2 eggs
- 100 ml sour cream (unsweetened)
- Salt and pepper (to taste)
- Cumin (optional, for extra flavor)
- 75 g smoked sausage or bacon (optional, for a richer taste)

Instructions:

1. Activating the yeast: Start by dissolving the fresh yeast along with the sugar in 50 ml of the lukewarm milk. Let the mixture sit covered for 10 minutes until it becomes frothy. This step is essential for achieving a fluffy dough.

2. Preparing the dough: In a large bowl, sift the flour and make a well in the center. Add the activated yeast, salt, and thyme (if using). Pour in the remaining lukewarm milk and begin kneading the dough. As the dough starts to form, add the melted butter. Continue kneading until the dough is elastic and no longer sticks to your hands. Cover the bowl with a clean towel and let it rise in a warm place for about 1 hour, until it doubles in size.

3. Preparing the filling: While the dough is rising, prepare the filling. Melt 50 g of butter in a pan over medium heat and add the sliced onions. Sauté the onions, stirring constantly, until they become translucent and soft (about 10 minutes). Once the onions are ready, remove the pan from the heat and add 1 tablespoon of flour, mixing well to avoid lumps. Allow the filling to cool slightly.

4. Finalizing the filling: In a separate bowl, beat the eggs and add the sour cream. Season with salt, pepper, and cumin if desired. Incorporate the cooled onion mixture into the egg and sour cream mixture. Mix well until you achieve a homogeneous filling.

5. Assembling the tart: Preheat the oven to 180°C. Once the dough has risen, roll it out on a floured surface to create a sheet that completely covers a buttered tart pan (preferably 28 cm in diameter). Carefully lift the dough and place it in the pan, ensuring the edges are well covered.

6. Adding the filling: Pour the onion filling over the dough and level it with a spatula. If using smoked sausage or bacon, cut it into small pieces and sprinkle it evenly over the filling. Finish with a sprinkle of cumin and a few small pieces of butter.

7. Baking: Place the tart in the preheated oven and bake for 30-40 minutes, until the edges are golden and the filling is well cooked.

8. Serving: Allow the tart to cool slightly before slicing. You can serve it warm or cold, alongside a glass of red wine, which will highlight the delicious flavors of the onions and sausage.

Helpful tips:
- Use different types of onions (white, yellow, red) to vary the flavors.
- If you want a vegetarian version, you can omit the sausage and add vegetables like peppers or mushrooms.
- The tart can be stored in the refrigerator for 2-3 days and can be reheated in the oven, maintaining its crispy texture.

Nutritional benefits:
Onion tart is a good source of fiber, vitamins, and minerals, thanks to its high onion content. Onions are known for their antioxidant and anti-inflammatory properties, contributing to the maintenance of cardiovascular health. Additionally, the eggs and sour cream add a portion of protein and calcium, making this tart a nutritious and satisfying dish.

Frequently asked questions:
- Can I use dry yeast instead of fresh yeast?

- How can I vary the filling?
You can add goat cheese, feta cheese, or olives for a more interesting flavor.
