The Story of the Recipe

The origins of the Alsatian onion tart are deeply rooted in culinary traditions that emphasize simple ingredients and cooking techniques that highlight natural flavors. This tart has evolved over time in regions with a rich agricultural culture, where onions were a staple ingredient in daily diets. Today, the Alsatian tart is appreciated for its crispy texture and rich filling, becoming a symbol of conviviality and the joy of eating together.

Preparing the Dough

1. Preparing the ingredients: Start by preparing all the ingredients. Make sure the butter is cold, as this will help achieve a flaky tart.

2. Mixing the ingredients: In a large bowl, combine the flour and salt. Add the diced butter and, using your fingers, crumble it into the flour until you achieve a texture similar to wet sand.

3. Adding the eggs: Make a well in the center of the flour mixture and add the eggs. Begin mixing with a spatula, being careful not to over-knead the dough.

4. Hydrating the dough: Gradually add the cold water, one tablespoon at a time, until the dough comes together and becomes smooth. Form it into a ball, wrap it in plastic wrap, and refrigerate for at least 30 minutes.

Preparing the Filling

5. Caramelizing the onions: In a large skillet, add a teaspoon of butter over medium heat. Add the sliced white onion and red onion. Cook for about 15-20 minutes, stirring frequently, until they become soft and golden. Add a pinch of sugar to enhance the sweetness.

6. Adding the bacon: Cut the bacon into cubes and add it to the skillet, continuing to cook until it becomes crispy. This step will add a salty and savory flavor, balancing the sweetness of the onions.

7. Mixing the ingredients: Once the onion and bacon mixture has cooled slightly, transfer it to a large bowl. Add the grated cheese, eggs, liquid cream or sour cream, and then season with salt, pepper, and nutmeg to taste. Mix well to combine all the ingredients.

Assembling and Baking the Tart

8. Preparing the pan: Preheat the oven to 200°C. Remove the dough from the refrigerator and roll it out on a floured surface until you achieve a thin sheet. Place the tart dough in a greased tart pan, making sure to adjust it along the edges.

9. Preparing the dough: Use a fork to prick the dough in several places, which will help prevent air bubbles from forming during baking.

10. Adding the filling: Pour the onion and bacon filling over the crust, ensuring it is evenly distributed.

11. Baking: Bake the tart in the preheated oven for 30-35 minutes, or until the top is golden and the filling is set.

Serving and Suggestions

Once the tart is ready, let it cool for a few minutes before slicing. You can serve it warm or cold, alongside a fresh green salad for a delicious contrast.

Serving suggestions: Add a few strips of arugula or a light vinaigrette to complement the rich flavor of the tart.

Variations: You can experiment with other types of cheese, such as feta or mozzarella, or add herbs like thyme or rosemary for an extra flavor boost.

Nutritional Benefits

This tart offers a balanced combination of protein from the eggs and bacon, carbohydrates from the flour, and nutrients from the onions, which are known for their antioxidant properties. When consumed in moderation, the Alsatian tart can be a good choice for a satisfying meal.
